The deep branch, which is the dorsal scapular artery, supplies blood to the levator scapulae muscle, the rhomboid muscles, and part of the trapezius muscle, which are superficial muscles of the upper back.
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.
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).

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.Where does the deep cervical artery come from?
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 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 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%).
What are cervical veins?
The deep cervical vein (posterior vertebral or posterior deep cervical vein) accompanies its artery between the Semispinales capitis and colli. It begins in the suboccipital region by communicating branches from the occipital vein and by small veins from the deep muscles at the back of the neck.What are deep cervical lymph nodes?
Anatomical terminology The deep cervical lymph nodes are a group of cervical lymph nodes found near the internal jugular vein in the neck.
What does superior thoracic artery supply?The main function of this artery is to provide blood supply for the pectoralis major, pectoralis minor, subclavius and serratus anterior muscles. … Additionally, it supplies the muscles and adjacent skin of the first two intercostal spaces.
Article first time published onWhat 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 is the brachial artery?
The brachial artery is the extension of the axillary artery starting at the lower margin of the teres major muscle and is the major artery of the upper extremity. The brachial artery courses along the ventral surface of the arm and gives rise to multiple smaller branching arteries before reaching the cubital fossa.
What does lateral thoracic artery supply?
The lateral thoracic artery supplies the axillary lymph nodes, serratus anterior, pectoralis major, pectoralis minor and subscapularis muscles. … Additionally, it can provide blood supply to the breast in females.
What is the profunda brachii artery?
The profunda brachii artery also referred to as the deep brachial artery, is the first and largest branch of the brachial artery. It originates from the posterior portion of the brachial artery, just inferior to the lower border of the teres major muscle.
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 does the Musculophrenic artery supply?
The function of the musculophrenic artery is to provide blood supply to the muscles of the thoracic wall, together with the superior intercostal artery, branches from the thoracic part of the descending aorta, and the subcostal and superior thoracic arteries.
Which artery supplies blood to most of the cerebrum?
The brain receives blood from two sources: the internal carotid arteries, which arise at the point in the neck where the common carotid arteries bifurcate, and the vertebral arteries (Figure 1.20). The internal carotid arteries branch to form two major cerebral arteries, the anterior and middle cerebral arteries.
What 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 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.
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.
Which muscle is supplied by suprascapular nerve?
The suprascapular nerve has a motor and sensory innervation. Its motor innervation is to the supraspinatus and infraspinatus muscles. The supraspinatus and infraspinatus muscles are two of the four muscles that make up the glenohumeral (shoulder) joint.
What is the function of cervical lymph nodes?
Cervical lymph nodes, like the rest of the body’s lymph nodes, are responsible for fighting infection. They do this by attacking and destroying germs that are carried into the node through lymph fluid.
Are supraclavicular lymph nodes deep?
[3][4] If classified by region, the supraclavicular lymph nodes would qualify as inferior deep cervical nodes.
What does a swollen supraclavicular lymph node mean?
Enlarged lymph nodes above the collarbone: Enlarged lymph nodes above the collarbone (supraclavicular lymphadenopathy) are always considered abnormal. These generally suggest cancer or an infection in the region close by. Examples include lung infection, lung cancer, lymphoma in the chest cavity, or breast cancer.
What does the transverse cervical vein 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.
How deep in the neck is the jugular vein?
Right Internal Jugular Approach The internal jugular vein is located deep to the confluence of the two heads of the sternocleidomastoid muscle (SCM). More specifically, it is located deep to the clavicular head of the SCM, about one-third of the distance from the medial border to the lateral border of the muscle.
How many veins are in the neck?
The internal jugular vein is a major blood vessel that drains blood from important body organs and parts, such as the brain, face, and neck. Anatomically, there are two of these veins that lie along each side of the neck.
Does superior thoracic artery supply Subclavius?
It runs medially along the superior border of the pectoralis minor muscle, inferior to the subclavius and distal to the lateral border of the first rib — branches of the superior thoracic artery supply the first and second intercostal spaces.
What does the Thoracodorsal artery supply?
The thoracodorsal artery supplies predominantly the latissimus dorsi muscle but also gives branches to the serratus anterior muscle, the axillary skin, the subscapular and teres major muscles.
