what actually is the trapezius?
The trapezius muscle is a flat, thin muscle that lies directly under the horse's skin. But it's not much wider than one or two fingers, even in a very well-trained horse. The first part runs from the neck to the side of the shoulder blade; the second part runs from the shoulder blade to the thoracic vertebrae.
there is actually 2 type of trapezius on a horses body....
these are called cervical trapezius and thoracic trapezius. it is a beautiful, fan-shaped superficial muscle originating on the nuchal and supraspinatus ligaments from C2 to T10, having a cervical and thoracic portion. The cervical portion inserts on the entire spine of the scapula, while the thoracic portion inserts only in the dorsal third of the scapular spine.
The trapezius muscle in horses, like in humans and other mammals, is an important muscle involved in the movement and support of the neck, shoulders, and forelimbs. Here are some key facts about the trapezius muscle in horses:
Location:
The trapezius muscle in horses is located in the upper back and neck region. It extends from the withers (the highest point of the shoulder) to the nuchal crest (the bony ridge at the back of the horse's neck).
Function:
The trapezius muscle in horses plays a crucial role in several movements, including lifting and lowering the head, flexing and extending the neck, and stabilising the shoulder and forelimb during locomotion. It assists in controlling the position and movement of the scapula (shoulder blade) and influences the horse's balance and posture.
Shape and Structure:
The trapezius muscle in horses is triangular in shape, with a broad base and a tapering apex. It consists of three main parts: the descending (or lateral) portion, the transverse (or middle) portion, and the ascending (or medial) portion. These segments contribute to different movements and functions of the muscle.
The trapezius muscle is considered one of the major muscles of the horse's back and is essential for the horse's overall movement and coordination. Its development and strength can vary depending on the horse's breed, conformation, and individual training.
here is 3 added facts!
- Attachment Points:
The trapezius muscle in horses has various attachment points along the spine, including the spinous processes of the thoracic and lumbar vertebrae. It also attaches to the scapula (shoulder blade) and the fascia of the neck. This extensive attachment allows the trapezius muscle to provide stability and support to the neck and back.
- Development and Conditioning:
The development and conditioning of the trapezius muscle can significantly impact a horse's performance. Through specific exercises, such as long and low stretching or collected work, the trapezius muscle can be targeted and strengthened, enhancing the horse's ability to engage the hindquarters, maintain balance, and execute precise movements.
- Massage and Therapy:
The trapezius muscle is often a focal point for massage and therapy in horses. Tension, stiffness, or soreness in the trapezius muscle can result from issues such as poor saddle fit, incorrect training techniques, or muscular imbalances. Targeted massage and therapy techniques can help alleviate discomfort, improve circulation, and promote overall muscle health.
