Prevertebral muscles
Prevertebral Muscles
The Prevertebral Muscles are a group of muscles located in the neck region, anterior to the vertebral column. They are involved in the movement and stabilization of the cervical spine. The group includes the longus colli, longus capitis, rectus capitis anterior, and rectus capitis lateralis.
Etymology[edit | edit source]
The term "prevertebral" is derived from the Latin words "prae" meaning "before" and "vertebra" referring to the bones of the spine. Thus, "prevertebral" literally means "before the vertebrae".
Anatomy[edit | edit source]
The prevertebral muscles are located deep in the neck, anterior to the vertebral column. They are covered by the prevertebral fascia, a layer of connective tissue.
Longus Colli[edit | edit source]
The longus colli is the largest of the prevertebral muscles. It extends from the base of the skull to the third thoracic vertebra. It is involved in flexion, lateral flexion, and rotation of the neck.
Longus Capitis[edit | edit source]
The longus capitis is a broad, flat muscle that lies on the anterior surface of the vertebral column. It is involved in flexion and rotation of the head.
Rectus Capitis Anterior[edit | edit source]
The rectus capitis anterior is a small, short muscle that extends from the base of the skull to the first cervical vertebra. It is involved in flexion and rotation of the head.
Rectus Capitis Lateralis[edit | edit source]
The rectus capitis lateralis is a small muscle that extends from the first cervical vertebra to the temporal bone. It is involved in lateral flexion of the head.
Function[edit | edit source]
The prevertebral muscles play a crucial role in the movement and stabilization of the cervical spine. They allow for flexion, extension, lateral flexion, and rotation of the neck and head.
