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.
What does the deep transverse cervical artery supply?
The transverse cervical artery (also called the transverse artery of the neck) is a small blood vessel located in your neck. This artery provides blood supply to your trapezius muscle, a large muscle in your back that helps raise your arms.
What does 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%).
What is transverse cervical?
The transverse cervical nerve (superficial cervical or cutaneous cervical) arises from the second and third spinal nerves, turns around the posterior border of the sternocleidomastoideus about its middle, and, passing obliquely forward beneath the external jugular vein to the anterior border of the muscle, it …Where is the transverse cervical vein?
Venous anatomy of the region In general, the arteries in the neck are accompanied by two veins. These venae comitantes drain into a large vein crossing the neck horizontally, the so-called transverse cervical vein.
What does circumflex scapular artery supply?
The circumflex scapular artery is the largest terminal branch of the subscapular artery. … They contribute to the blood supply of three muscles (deltoid, teres minor, triceps brachii), glenohumeral joint and two small cutaneous areas partially overlying the scapula.
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.
What 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.What does the transverse cervical nerve innervate?
The transverse cervical nerve, also known as the superficial cervical nerve, cutaneous cervical nerve or anterior cutaneous cervical nerve of the neck, is a cutaneous branch of the cervical plexus that innervates the skin covering the anterior cervical region.
What nerves are in the cervical plexus?An assortment of branches arises from the cervical plexus and includes the ansa cervicalis, lesser occipital, greater auricular, supraclavicular, transverse cervical, and phrenic nerves.
Article first time published onWhat artery is above collar bone?
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 arteries supply the infraspinatus?
The infraspinatus is supplied arterially by the suprascapular and circumflex scapular arteries. The suprascapular artery either originates from the thyrocervical trunk or the subclavian artery.
What artery supplies the teres minor?
The teres minor is supplied by the subscapular artery and one of its branches, the circumflex scapular artery, as well as the posterior circumflex humeral artery. The subscapular artery and the posterior circumflex humeral artery arise from the third, most distal portion of the axillary artery.
What does the superficial cervical artery supply?
The transverse (middle) part of the trapezius is supplied by the superficial cervical artery (SCA; superficial branch of the transverse cervical artery). The ascending (inferior) part of the trapezius is supplied by the dorsal scapular artery (DSA; deep branch of the transverse cervical artery).
Where is deep cervical artery?
The deep cervical artery is a branch of the costocervical trunk of the subclavian artery on each side. It originates anterior to the neck of the first rib. It then passes superiorly and arches inferior to the transverse process of the C7 vertebra.
Where is the vertebral vein?
The vertebral vein is a paired vessel found in the transverse foramina of the cervical vertebrae on either side of the neck. It arises at the level of the sixth cervical vertebra from a venous plexus that surrounds the vertebral artery and travels as far as the brachiocephalic veins.
What does the internal thoracic artery supply?
The internal thoracic artery functions to supply the anterior chest wall, from the clavicle to the umbilicus. This area of supply also includes supply to the sternum and breasts.
What 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.
What is the brachial artery?
The brachial artery is the main vessel supplying blood to the muscles in your upper arm and elbow joint. It’s often used to measure your blood pressure. The brachial artery is near the surface of your skin, so it’s susceptible to damage from traumatic injuries like arm fractures.
What does anterior circumflex humeral artery supply?
The anterior humeral circumflex artery runs horizontally, beneath the coracobrachialis and short head of the biceps brachii muscle, in front of the neck of the humerus. On reaching the intertubercular sulcus, it gives off a branch which ascends in the sulcus to supply the head of the humerus and the shoulder-joint.
What is circumflex artery?
The circumflex artery branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the outer side and back of the heart.
What does the posterior humeral circumflex artery supply?
Supply. The posterior circumflex humeral artery provides part of the blood supply to the glenohumeral joint, teres major and minor, and deltoid muscles 1.
What muscles in the neck do the nerves of the cervical plexus innervate?
The muscular branches pass deeply from the plexus to supply the rhomboids, the serratus anterior, the sternocleidomastoid, the trapezius, levator scapulae, and the scalenus medius. There are also branches that supply the muscles of the suboccipital triangle.
What is scapular anastomosis?
The scapular anastomosis is a system connecting certain subclavian artery and their corresponding axillary artery, forming a circulatory anastomosis around the scapula. It allows blood to flow past the joint in case of occlusion, damage, or pinching of the following scapular arteries: Transverse cervical artery.
What artery supplies the levator scapulae?
Blood supply The levator scapulae is supplied by the dorsal scapular artery. Normally, this artery has a small branch which passes laterally to the supraspinatus fossa of the scapula, and in a third of cases, this branch supplies the muscle.
What gives rise to the dorsal scapular 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 is the main nerve in the cervical plexus?
Cervical plexusFMA5904Anatomical terms of neuroanatomy
What is the most important nerve of the cervical plexus?
The most important clinical correlate with respect to the cervical plexus is the injury of the phrenic nerve, an important branch of the cervical plexus. Phrenic nerve severance or injury results in the paralysis of one half of the diaphragm.
What cervical plexus Innervates the diaphragm?
The phrenic nerve arises from the anterior rami of C3-C5. It provides motor innervation to the diaphragm. After arising from the cervical plexus, the nerve travels down the surface of the anterior scalene muscle and enters the thorax.
What is the space between your collarbones called?
The thoracic outlet is a narrow space between your collarbone (clavicle) and your first rib. Nerves and blood vessels exit from your chest to your arm through this space.
What causes Costoclavicular syndrome?
A scissoring action of the clavicle against the first rib narrows the costoclavicular passage and shears the neurovascular bundle. The first rib elevates toward/against the clavicle. This often occurs in clients who have laboured breathing. Tight anterior and middle scalenes and subclavius can also cause this to occur.
