Is the transverse cervical artery the same as the dorsal scapular artery?
Structure. As mentioned above, it divides into two branches: A superficial branch, which is the superficial cervical artery, travels upward after it branches from the transverse cervical artery. A deep branch, which is the dorsal scapular artery, travels downward after it branches from the transverse cervical artery.
How do you find a transverse cervical artery?
The transverse cervical artery arises from the thyrocervical trunk and can be located at the root of the neck accompanied by the transverse cervical vein (see Figure 4.1).
Where is the 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 is dorsal scapular artery?
The dorsal scapular artery is a branch of either the transverse cervical artery (from the thyrocervical trunk off the first part of the subclavian artery) or an independent branch from the third (or less commonly second) part of the subclavian artery.
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.
Where is superficial branch of the transverse cervical artery?
Superficial branch: It ascends beneath the anterior margin of the trapezius, distributing branches to it, and to the neighboring muscles and lymph glands in the neck, and anastomosing with the superficial branch of the descending branch of the occipital artery. It has an ascending branch and a descending branch.
What does transverse cervical artery supply?
Supplies. The trapezius and Sternocleidomastoid muscles.
What does the dorsal scapular artery innervate?
The dorsal scapular nerve branches from the ventral ramus of C5 and descends from the cervical region down to the medial border of the scapula. It innervates three muscles: the levator scapulae, the rhomboid major, and the rhomboid minor.
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 is cervical plexus?
cervical plexus: plexus of nerves that supply the neck muscles with branches named by muscles supplied, a portion of which is called the ansa cervicalis. facial nerve: supplies some facial muscles and sensation; also called seventh cranial n.
What happens if the subclavian artery is blocked?
The symptoms that do occur are tied to the area that is blocked. You may experience arm pain or muscle fatigue when using your arms above your head, or doing any activity that demands more oxygen-rich blood flow to the arms. Other symptoms can include: Dizziness (vertigo) with arm activity.
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.
