The costocervical trunk is a short artery that usually stems from the upper portion of the distal segment of the subclavian artery, distal to the thyrocervical trunk. The origin of the costocervical trunk is located at the level of the lower pole of the inferior (cervicothoracic/stellate) ganglion.

What does thyrocervical trunk mean?

The thyrocervical trunk is one of the 3 branches of the first part of the subclavian artery and gives off numerous branches to supply viscera of the neck, the brachial plexus, neck muscles and the scapular anastomosis.

What does Costocervical mean?

[kos″to-ser´vĭ-k’l] pertaining to the ribs and neck.

Where does the thyrocervical trunk supply?

Primarily, the thyrocervical trunk is tasked with supplying oxygenated blood to the viscera of the neck, which includes the thyroid and parathyroid glands, the trachea and larynx, as well as the pharynx and esophagus in the throat.

Are there two Thyrocervical trunks?

The thyrocervical trunk can have up to five branches, but in most cases, it has two to four. These branches usually include: inferior thyroid artery, suprascapular artery, ascending cervical artery and the transverse cervical artery.

What does costocervical trunk come off of?

Though there may be some variation, the costocervical trunk arises from the upper portion of the distal segment of the subclavian artery, which is the portion that runs outward toward the shoulders.

What is the brachiocephalic trunk?

The brachiocephalic artery, brachiocephalic trunk, or more commonly referred to clinically as the innominate artery, is one of the three great vessels of the aortic arch that supplies blood to the head, neck and upper extremities.

What is the carotid triangle?

The carotid triangle includes the common carotid artery and its bifurcation into the external carotid artery (ECA) and internal carotid artery (ICA). It usually contains the superior thyroid, lingual, facial, occipital, and ascending pharyngeal arteries.

Where do intercostal arteries come from?

The first two intercostal arteries arise from the highest intercostal artery. The highest intercostal artery is a branch of the costocervical trunk, which arises from the subclavian artery. The intercostal arteries course between the intercostal vein superiorly and the intercostal nerve inferiorly.

Where is the Suprascapular artery?

The suprascapular artery is a branch of the thyrocervical trunk, which emerges from the first part of the subclavian artery. It runs across the front of your neck and behind the clavicle (collarbone) to supply blood to the muscles, skin, and bones in your chest and shoulder.

Where is aortic arch?

The aortic arch is the section of the aorta between the ascending and descending aorta. As it arises from the ascending aorta, the arch runs slightly backward and to the left of the trachea. The distal segment of the aortic arch then traverses downwards at the fourth thoracic vertebra.

What comes off of thyrocervical trunk?

Visible branches of the thyrocervical trunk include the (3) inferior thyroid artery, (4) ascending cervical artery, and (5) suprascapular artery. Note faint vascular blush of the thyroid gland at distal branches of the (3) inferior thyroid artery. Distally, the (6) costocervical trunk opacifies.

How many branches come off of the Thoracoacromial trunk?

The thoracoacromial artery travels a short course deep to the medial border of the pectoralis minor muscle and then passes through the clavipectoral fascia. It then divides into four branches including the clavicular, acromial, pectoral, and deltoid branches 2.

Where is the Thoracodorsal artery?

The thoracodorsal artery is a terminal branch of the subscapular artery that originates in the axillary region. It runs inferomedially along the lateral border of the scapula, then courses posteriorly passing deep to the latissimus dorsi muscle.

What is the facial artery?

The facial artery is a branch of the external carotid artery that supplies the anatomic structures of the superficial face. The facial artery arises from the carotid triangle which is formed by the superior belly of the omohyoid muscle, the sternocleidomastoid, and the posterior belly of the digastric.
