What are the branches of the transverse cervical artery?
What are the branches of the transverse cervical artery?
As the transverse cervical artery travels underneath the omohyoid muscle in the neck, it extends further back in the neck near the anterior (front) portion of the trapezius muscle, where it divides into two smaller branches, the superficial cervical artery and the dorsal scapular artery.
What does transverse cervical artery supply?
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 transverse cervical nerve do?
The transverse cervical nerves will pass horizontally directly over the SCM from Erb’s point….
| Transverse cervical nerve | |
|---|---|
| From | cervical plexus (C2 and C3) |
| Innervates | Cutaneous innervation of the anterior and lateral parts of the neck |
| Identifiers | |
| Latin | nervus transversus colli |
What does the 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 muscle is supplied by the transverse cervical vein?
The transverse cervical artery provides the dominant blood supply of the trapezius muscle.
What are the branches of axillary artery?
It has three branches that are variable in their order: the subscapular trunk, the anterior humeral circumflex artery, and the posterior humeral circumflex artery.
What does ascending cervical artery supply?
The ascending cervical artery helps to supply the neck musculature and the posterior elements of the cervical vertebrae. b. Superficial (transverse) cervical artery. This artery supplies the superficial and deep back muscles of the cervical and upper thoracic regions.
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.
What nerve supplies the diaphragm?
The phrenic nerve originates from the anterior rami of the C3 through C5 nerve roots and consists of motor, sensory, and sympathetic nerve fibers. It provides complete motor innervation to the diaphragm and sensation to the central tendon aspect of the diaphragm.
What nerves make up the cervical plexus?
The cervical plexus is formed from the anterior primary rami of C1–C4, deep to the sternocleidomastoid muscle and in front of the scalenus medius and levator scapulae muscles. Sensory branches include the greater and lesser occipital nerves, great auricular nerve, cutaneous cervical nerves, and supraclavicular nerves.
What does the dorsal scapular nerve innervate?
The DSN is a motor nerve that innervates the levator scapulae, rhomboid major, and rhomboid minor muscles. These muscles work dynamically and collectively are considered periscapular stabilizing muscles. Individually they can retract and elevate the scapula.
What gives rise to the dorsal scapular artery?
The dorsal scapular artery (or descending scapular artery) is a blood vessel which supplies the levator scapulae, rhomboids, and trapezius. It most frequently arises from the subclavian artery (the second or third part), but a quarter of the time it arises from the transverse cervical artery.
