The Anatomy and Function of the Poll

Understanding the anatomy and function of the poll area is crucial for maintaining a horse's health and performance. The poll, located at the top of the head, plays a key role in the horse's overall mobility and comfort. This area includes important structures such as the atlas and axis vertebrae, the temporomandibular joint (TMJ), and the temporalis muscle. Each of these components contributes to the horse's ability to move, eat, and perform effectively. By exploring the specific functions and common issues associated with these structures, we can better appreciate the importance of proper poll care and the benefits of innovative solutions like the EquineGlow Poll device.


Atlas and Axis Vertebrae

The atlas (C1) and axis (C2) vertebrae are the first two vertebrae in a horse's spine and are crucial for the extensive range of motion in the horse's head and neck. The atlas, being the first cervical vertebra, supports the skull and allows for the nodding motion of the head (up and down movement). The axis, the second cervical vertebra, enables the rotation of the head (side to side movement). Together, these vertebrae provide the most mobility in the horse's spine, second only to the tail. This mobility is essential for various daily activities, including grazing, drinking, and responding to rider cues. A healthy and flexible poll area allows the horse to perform these actions smoothly and without discomfort.


Common Issues

Poll tension is a common issue that can arise from multiple factors, including poor riding habits, improper equipment, aging, or injury. When a horse is ridden with improper technique, or when the tack does not fit correctly, it can place undue stress on the poll area, leading to tension and discomfort. Additionally, as horses age, the natural wear and tear on their bodies can also result in poll tension. Injuries, whether from accidents or repetitive strain, can further exacerbate this issue.


Signs of poll tension include resistance to bending and difficulty in flexing the neck. A horse with poll tension may show stiffness and reluctance to perform tasks that require head and neck movement. This can be particularly evident during riding, where the horse might resist contact with the bit or show discomfort when asked to flex or bend. In severe cases, the horse might display signs of pain, such as head tossing, ear pinning, or overall irritability.


Addressing poll tension is crucial for maintaining a horse's comfort and performance. Regular check-ups with an equine chiropractor or physiotherapist can help identify and alleviate poll tension. Ensuring that the tack fits correctly and that the horse is ridden with proper technique can also prevent the development of tension in the first place. For horses already experiencing poll tension, therapies such as massage, acupressure, and red light therapy can provide significant relief. The EquineGlow Poll device, for instance, uses advanced red light therapy to target the poll area, helping to alleviate tension and promote overall well-being.


Temporomandibular Joint (TMJ)

the TMJ is important to keep healthy in horses and the poll cap can help

The temporomandibular joint (TMJ) is a pivotal component in a horse's anatomy, crucial for chewing and overall jaw movement. This joint connects the lower jaw (mandible) to the skull, allowing for the opening and closing of the mouth as well as lateral (side-to-side) movements necessary for grinding food. The TMJ's proper function is vital for a horse's ability to eat efficiently and comfortably. Beyond feeding, the TMJ also plays a significant role in a horse's performance, particularly in activities that require bit acceptance and responsiveness to rein aids. A healthy TMJ ensures that the horse can move its jaw freely, facilitating smooth and effective communication between the horse and rider.


Common Issues

TMJ tension or soreness is a common problem that can significantly impact a horse's comfort and performance. This tension often stems from dental issues, such as improperly shaped or misaligned teeth, which can create uneven pressure and strain on the TMJ. When a horse's teeth are not correctly aligned, the chewing motion becomes inefficient, causing the jaw muscles to overwork and leading to TMJ tension. Regular dental care, including floating (filing down) the teeth, is essential to maintain proper alignment and function.

Symptoms of TMJ problems can vary but often include:

  • Difficulty Chewing: Horses with TMJ tension may struggle to chew their food properly, leading to slower eating times, incomplete digestion, and potential weight loss.

  • Head Shaking: Horses may exhibit head shaking or tossing as a sign of discomfort or pain in the jaw area. This behavior is often a response to the constant strain on the TMJ.

  • Reluctance to Accept the Bit: A horse experiencing TMJ soreness may be unwilling to take the bit or may show discomfort when pressure is applied through the reins. This can manifest as resistance to bridling, head tossing, or general irritability under saddle.


Addressing TMJ issues requires a multifaceted approach. Regular dental check-ups by an equine dentist or veterinarian can help identify and correct dental problems before they lead to severe TMJ tension. Additionally, ensuring that the horse's tack fits correctly, especially the bridle and bit, can help minimize undue pressure on the TMJ.


Therapies such as massage, acupressure, and red light therapy can provide significant relief for horses suffering from TMJ tension. The EquineGlow Poll device, for instance, uses red light therapy to target the TMJ area, helping to alleviate soreness and improve overall jaw function. This advanced therapy promotes increased blood circulation, reduces inflammation, and accelerates the healing process, making it an effective solution for managing TMJ-related issues and enhancing a horse's comfort and performance.


Temporalis Muscle

The temporalis muscle is a significant muscle involved in the chewing process and plays a crucial role in supporting the jaw. It is a broad, fan-shaped muscle located on the top and side of the head, stretching from the temporal fossa (a shallow depression on the skull) to the coronoid process of the mandible (the upper part of the jawbone). The temporalis muscle's primary function is to elevate the mandible, allowing the horse to close its mouth and grind food efficiently. This muscle works in conjunction with other masticatory muscles to facilitate the complex movements required for chewing, ensuring that food is adequately broken down for digestion. The temporalis muscle is easily visible on the forehead, near the forelock hair, especially when it contracts during chewing.


Common Issues

Overdevelopment or tension in the temporalis muscle is a common issue that can arise due to various factors, primarily related to dental health. When a horse has dental problems such as uneven teeth, sharp edges, or malocclusions, it can lead to improper chewing mechanics. To compensate for these dental irregularities, the temporalis muscle may become overworked, resulting in tension and hypertrophy (overdevelopment). This excessive strain can lead to muscle bulging, making the temporalis muscle visibly more prominent on the horse's forehead.


Signs of issues with the temporalis muscle include:

  • Muscle Bulging: One of the most noticeable signs of overdevelopment or tension in the temporalis muscle is the visible bulging on the forehead. This bulging can be observed as two lumps near the forelock hair, which become more pronounced when the horse is chewing.

  • Uneven Muscle Development: Horses with dental issues may exhibit asymmetrical muscle development, where one side of the temporalis muscle is more developed than the other. This imbalance can be a clear indicator of underlying dental problems and the horse's attempt to compensate for discomfort.

  • Discomfort During Chewing: Tension in the temporalis muscle can cause significant discomfort for the horse while chewing. Signs of discomfort include reluctance to eat, slow or hesitant chewing, and dropping partially chewed food. The horse may also display general irritability and discomfort during feeding times.


Addressing issues with the temporalis muscle requires a comprehensive approach focusing on dental health and muscle relief. Regular dental examinations and treatments, such as floating (filing down) the teeth, are essential to correct any misalignments and ensure proper chewing mechanics. This preventative care helps reduce the strain on the temporalis muscle, preventing overdevelopment and tension.

In addition to dental care, therapeutic interventions can provide significant relief for horses suffering from temporalis muscle tension. Massage therapy can help relax the muscle and alleviate tension, promoting better blood flow and reducing discomfort. Acupuncture and acupressure can also be effective in targeting specific points to relieve muscle stress.


Red light therapy, such as that provided by the EquineGlow Poll device, is another valuable tool for managing temporalis muscle issues. Red light therapy works by penetrating the muscle tissue with light wavelengths that promote increased blood circulation, reduce inflammation, and accelerate the healing process. By using the EquineGlow Poll device, horse owners can target the temporalis muscle specifically, helping to relieve tension, reduce visible bulging, and improve the horse's overall comfort and ability to chew efficiently.


In summary, the temporalis muscle plays a vital role in a horse's chewing process and jaw support. Regular dental care, combined with therapeutic interventions like red light therapy, can help prevent and alleviate issues related to muscle overdevelopment and tension, ensuring that the horse remains comfortable and healthy.


The Role of Red Light Therapy in Addressing Poll Tension

Red light therapy is a non-invasive therapy that uses specific wavelengths of red light to penetrate deep into tissues, promoting healing and reducing inflammation. This therapy has been widely used in both human and veterinary medicine due to its therapeutic benefits, which include pain relief, enhanced tissue repair, and improved circulation. The process involves exposing the affected area to red light, typically through a device designed to emit these wavelengths.


Therapeutic Benefits of Red Light Therapy

The therapeutic benefits of red light therapy are extensive and particularly beneficial for addressing poll tension in horses. Some of the key benefits include:

  • Pain Relief: Red light therapy helps reduce pain by stimulating the production of endorphins and other natural pain-relieving chemicals in the body.

  • Reduced Inflammation: The light penetrates the skin and underlying tissues, reducing inflammation by decreasing the production of pro-inflammatory cytokines and increasing the production of anti-inflammatory cytokines.

  • Enhanced Tissue Repair: Red light stimulates cellular processes that promote tissue repair and regeneration. This includes increased ATP (adenosine triphosphate) production, which provides cells with the energy needed to repair and regenerate.

  • Improved Circulation: The therapy promotes vasodilation, which increases blood flow to the affected area, delivering more oxygen and nutrients necessary for healing.


The Science Behind Red Light Therapy

Red light therapy operates on the principle of photobiomodulation, where light energy is absorbed by cellular photoreceptors, leading to biological changes. Here’s a closer look at how it works:

  • Light Absorption: Red light, typically in the wavelength range of 600 to 700 nanometers, is absorbed by chromophores within the cells. One of the primary chromophores is cytochrome c oxidase, a component of the mitochondrial respiratory chain.

  • Increased ATP Production: The absorption of red light by cytochrome c oxidase enhances the electron transport chain's activity in mitochondria, leading to increased ATP production. ATP is the energy currency of cells, and higher ATP levels accelerate cellular processes, including repair and regeneration.

  • Reduction of Oxidative Stress: Red light therapy helps reduce oxidative stress by enhancing the production of antioxidants within the cells. This reduction in oxidative stress further aids in reducing inflammation and promoting healing.

  • Gene Expression Modulation: Exposure to red light can influence gene expression, leading to the upregulation of genes associated with cellular repair and the downregulation of genes involved in inflammation. This modulation supports the overall healing process.
