== Deep Cervical Artery ==

The Deep Cervical Artery is a significant blood vessel in the human body that supplies blood to the muscles and structures in the neck region. It is a branch of the costocervical trunk, which itself is a branch of the subclavian artery.

Anatomy[edit | edit source]

The deep cervical artery typically arises from the costocervical trunk, which branches off from the subclavian artery. It ascends in the back of the neck, running between the semispinalis capitis and semispinalis cervicis muscles. The artery supplies blood to these muscles as well as to the cervical vertebrae and the spinal cord.

Function[edit | edit source]

The primary function of the deep cervical artery is to provide oxygenated blood to the muscles and structures in the posterior part of the neck. This includes the semispinalis capitis, semispinalis cervicis, and other deep muscles of the neck. It also contributes to the blood supply of the spinal cord in the cervical region.

Clinical Significance[edit | edit source]

Injuries or conditions affecting the deep cervical artery can lead to compromised blood flow to the neck muscles and the spinal cord. This can result in muscle weakness, pain, or more severe neurological deficits. Understanding the anatomy and function of the deep cervical artery is crucial for surgeons and clinicians dealing with neck injuries or surgeries.
