A Guide to the Muscles Neck

muscles neck

The muscles neck are important for the human head’s stability and alignment. The head weighs 8 to 15 pounds, which includes the brain, and is supported by the upper cervical vertebrae (the atlas and axis). These muscles must maintain balance. However, when an individual experiences structural abnormalities, the neck muscles may be negatively affected. If the weight of the head is unevenly distributed across the neck, the muscles will become stressed and spasm.

Scalene muscles

If you’re experiencing pain in the neck, you might be suffering from a trigger point in the Scalene muscles. These muscles can be easily targeted through trigger point massage. The scalenes neck muscles are located in front of the transverse processes, the sides of the vertebrae. Massage these muscles until you feel them twitch.

These muscles attach to the thoracic cage and help stabilize the spine. They also help lift the rib cage during respiration. They run from the neck down to the rib cage, where the subclavian artery travels. These arteries supply blood to the rib cage and the arm. The nerves of the brachial plexus run between the scalene muscles and the subclavian artery. They also innervate the neck muscles and supply sensory information to the entire arm.

Erector spinae muscles

The erector spinae muscles of the neck are responsible for the extension and rotation of the spine. These muscles are divided into three groups: longissimus, spinalis cervicis, and iliocostalis. All of these groups function to control the spinal column. The longissimus muscle is the largest of the erector spinae. In addition, it is the longest muscle in the human body.

The transversospinalis muscle group arises from the transverse processes of the cervical spine and passes between the erector spinae muscles. The erector spinae muscles and transversospinalis muscle are two of the deep intrinsic muscles. The erector spinas muscle originates from the sacrum and divides into three columns just below the last rib. The iliocostalis muscle inserts into the cervical transverse processes at C4-C6. The iliocostalis has six segments.

Trapezius muscle

The trapezius muscle is responsible for holding the spine in a neutral position, and it also helps stabilize the neck and shoulders during certain movements. When strained, this muscle can lead to severe discomfort and even a muscle tear. Proper stretching and strengthening exercises can help prevent strain. Moreover, a healthy diet and lifestyle are essential for maintaining the health of this muscle.

This muscle originates from the base of the neck and extends across the top of the shoulder. The upper portion helps tilt the head, and it also helps raise and lower the shoulder girdle. The middle part brings the shoulder blade back and assists with shoulder rotation.

Transversospinalis cervicis

The Transversospinalis cervix muscles help to tilt and stabilize the head. They extend from the base of the skull to the thoracic and lumbar spines. The other muscles that make up this group include the rectus capitis anterior and lateralis and the longus colli.

The Transversospinalis cervix is composed of four muscles that originate from the transverse processes of the vertebrae T1-T6. The semispinalis cervicis and longissimus cervicis attach to the spinous processes of vertebrae C2 to C5. These muscles stretch over the cervical region and are positioned on the spinous processes of the second, third, and fifth cervical vertebrae.

Transversohyoid muscle

The Transversohyoid muscle is located in the neck. It is a long muscle whose fibers pass medially and slightly downwards across the front portion of the hyoid bone. The muscle is innervated by the superior ramus of the ansa cervicalis and the hypoglossal nerve. Its attachment to the scapula is variable and ranges from millimeters to 2.5 cm.

This muscle is divided into two bellies by an intermediate tendon. Its central tendon originates on the scapula and inserts on the inferior surface of the hyoid bone. Its function is to elevate and depress the hyoid bone. It is located on the midline of the neck.
