The transverse cervical artery provides the dominant blood supply of the trapezius muscle. The trapezius flap remains an extremely useful regional flap for head and neck reconstruction, particularly for resurfacing defects of the posterior aspect of the head and neck such as the occipital region.
Where does the transverse cervical artery go?
The transverse cervical artery originates from the thyrocervical trunk, it passes through the posterior triangle of the neck to the anterior border of the levator scapulae muscle, where it divides into deep and superficial branches.
Is dorsal scapular artery the same as transverse cervical artery?
The dorsal scapular artery arises from the second or third part of the subclavian artery in 67% of sides. It is a branch of the transverse cervical artery in only 30%.
What comes off the thyrocervical trunk?
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 the suprascapular artery do?
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 the transverse facial artery?
The transverse facial artery (TFA) is found in the lateral face and supplies the parotid gland and duct, facial nerve, facial muscles, and skin.
What muscle is supplied by the transverse cervical vein?
The transverse cervical artery provides the dominant blood supply of the trapezius muscle.
What does ascending cervical artery supply?
The ascending cervical artery is a small branch that arises from either the inferior thyroid artery (in about 60% of people) or the thyrocervical trunk (30%). It gives off numerous small branches that supply the spinal cord, vertebral bodies and muscles of the neck.
Where is deep cervical artery?
The deep cervical artery arises from the costovertebral trunk and travels between the facet joints toward the posterior spinal muscles,45 while the occipital artery stems from the external carotid artery on its way to supply the posterior scalp.
What muscles does dorsal scapular artery supply?
The dorsal scapular artery (DSA) supplies the levator scapulae and rhomboid muscles, and contributes to the arterial anastomosis around the scapula.
Where is dorsal scapular artery located?
The scapular dorsal artery (DSA) is usually described as the last branch of the subclavian artery (SCA). In this case its origin is located below the anterior scalenus muscle.
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 are the branches 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.
What is the largest artery in the human body?
How large is the aorta? The aorta is the largest blood vessel in your body. It’s more than 1 foot long and an inch in diameter at its widest point.
Where does suprascapular artery come from?
The suprascapular artery usually originates from the thyrocervical trunk of the subclavian artery (Figure 1), before crossing the laterally situated scalenus anterior muscle, phrenic nerve, brachial plexus, and subclavian artery.
What is Subscap?
The subscapularis is the largest, strongest muscle of the rotator cuff. The rotator cuff muscles are important in shoulder movement and help maintain glenohumeral joint stability. The subscapularis muscle lies at the anterior surface of the scapula.
