The '''thyrocervical trunk''' arises from the anterior aspect of the [[subclavian artery]], posterior to the [[vagus nerve]] and anterior to the [[anterior scalene muscle]]. It ascends for a short distance and divides into four branches: the [[inferior thyroid artery]], [[transverse cervical artery]], [[suprascapular artery]], and [[ascending cervical artery]].
The '''thyrocervical trunk''' is a major artery of the [[neck]] that arises from the [[subclavian artery]]. It is an important vessel that supplies blood to several structures in the neck and upper back region.


=== Inferior Thyroid Artery ===
===Anatomy===
The thyrocervical trunk originates from the first part of the [[subclavian artery]], which is located just medial to the [[anterior scalene muscle]]. It is a short, thick vessel that quickly divides into several branches.


The [[inferior thyroid artery]] is the largest branch of the thyrocervical trunk. It ascends to the lower part of the [[thyroid gland]], supplying it with blood.
===Branches===
The thyrocervical trunk typically gives rise to three main branches:


=== Transverse Cervical Artery ===
* '''[[Inferior thyroid artery]]''': This artery ascends to supply the [[thyroid gland]], [[parathyroid glands]], and adjacent muscles and tissues.
* '''[[Transverse cervical artery]]''': This artery courses laterally across the neck, supplying the [[trapezius muscle]] and other structures in the posterior triangle of the neck.
* '''[[Suprascapular artery]]''': This artery travels laterally and posteriorly to supply the [[supraspinatus]] and [[infraspinatus]] muscles of the [[shoulder]].


The [[transverse cervical artery]] runs laterally in the posterior triangle of the neck, supplying blood to the [[trapezius]] and [[rhomboid muscles]].
In some individuals, a fourth branch, the [[ascending cervical artery]], may also arise from the thyrocervical trunk. This artery supplies the [[prevertebral muscles]] and the [[spinal cord]].


=== Suprascapular Artery ===
===Function===
The primary function of the thyrocervical trunk is to provide arterial blood supply to the thyroid gland, neck muscles, and parts of the shoulder. It plays a crucial role in maintaining the vascular supply to these regions, which is essential for their normal function.


The [[suprascapular artery]] runs laterally across the anterior scalene and phrenic nerve, supplying blood to the [[supraspinatus]] and [[infraspinatus muscles]].
===Clinical Significance===
 
The thyrocervical trunk is of clinical importance due to its proximity to other vital structures in the neck. It is often encountered during surgical procedures involving the neck, such as [[thyroidectomy]] or [[cervical lymph node dissection]]. Understanding its anatomy is crucial for avoiding vascular injury during such procedures.
=== Ascending Cervical Artery ===
 
The [[ascending cervical artery]] is a small branch that ascends on the anterior tubercles of the transverse processes of the cervical vertebrae, supplying them with blood.
 
== Clinical Significance ==
 
The thyrocervical trunk and its branches are important in several clinical scenarios. They can be involved in [[thyroid disorders]], [[neck injuries]], and [[surgical procedures]] in the neck region.

Thyrocervical Trunk[edit]

Diagram of the thyrocervical trunk and its branches.

The thyrocervical trunk is a major artery of the neck that arises from the subclavian artery. It is an important vessel that supplies blood to several structures in the neck and upper back region.

Anatomy[edit]

The thyrocervical trunk originates from the first part of the subclavian artery, which is located just medial to the anterior scalene muscle. It is a short, thick vessel that quickly divides into several branches.

Branches[edit]

The thyrocervical trunk typically gives rise to three main branches:

In some individuals, a fourth branch, the ascending cervical artery, may also arise from the thyrocervical trunk. This artery supplies the prevertebral muscles and the spinal cord.

Function[edit]

The primary function of the thyrocervical trunk is to provide arterial blood supply to the thyroid gland, neck muscles, and parts of the shoulder. It plays a crucial role in maintaining the vascular supply to these regions, which is essential for their normal function.

Clinical Significance[edit]

The thyrocervical trunk is of clinical importance due to its proximity to other vital structures in the neck. It is often encountered during surgical procedures involving the neck, such as thyroidectomy or cervical lymph node dissection. Understanding its anatomy is crucial for avoiding vascular injury during such procedures.
