What does thyrocervical trunk supply?

What does thyrocervical trunk supply?

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 vessels originate from the 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.

Is costocervical trunk the same as thyrocervical trunk?

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 the costocervical trunk supply?

The costocervical trunk is a branch of the subclavian artery which supplies the upper extremities and contributes partly to the blood supply of the head and neck.

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.

What does the suprascapular artery supply?

The suprascapular artery supplies the supra- and infraspinatus muscles and travels with the suprascapular nerve. It is a direct branch from the subclavian artery (12%), the thyrocervical trunk (27%) or the internal thoracic artery (11%).

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.

Where is the Thyrocervical artery?

The thyrocervical trunk is a branch of the subclavian artery arising from the first portion of this vessel, i.e. between the origin of the subclavian artery and the inner border of the scalenus anterior muscle. It is located distally to the vertebral artery and proximally to the costocervical trunk.

Where does the costocervical trunk arise from?

the subclavian artery
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 causes subscapularis pain?

In young people, an injury is the most common cause of a subscapularis tear. This usually happens when your arm is overextended. In older people, subscapularis tears are usually caused by age-related degeneration. Shoulder impingement can also cause a subscapularis tear.

Which muscle does the suprascapular artery supply?

The suprascapular artery supplies the supra- and infraspinatus muscles and travels with the suprascapular nerve.

What is the thyrocervical trunk?

The thyrocervical trunk is a wide vessel that arises from the first segment of the subclavian artery. It has a relatively short course in the anterior portion of the neck . The branches arising from this trunk are extremely variable.

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.

What is a thyrocervical dissection?

Superficial dissection of the right side of the neck, showing the carotid and subclavian arteries. The thyrocervical trunk is a branch of the subclavian artery arising from the first portion of this vessel, i.e. between the origin of the subclavian artery and the inner border of the scalenus anterior muscle.

Do the scapular and superficial cervical arteries arise separately?

In the rest, the dorsal scapular and superficial cervical arteries arise separately. The suprascapular artery and transverse cervical artery both head laterally and cross in front of (anterior to) the scalenus anterior muscle and the phrenic nerve.
