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%).
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 Musculophrenic artery supply?
The musculophrenic artery runs along the costal slips of the diaphragm. It supplies the 7th, 8th and 9th intercostal spaces with paired anterior intercostal arteries, as well as fine branches that supply the superior part of the anterior abdominal wall.
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.
Article first time published onWhat does C2 nerve innervate?
C1, C2, and C3 (the first three cervical nerves) help control the head and neck, including movements forward, backward, and to the sides. The C2 dermatome handles sensation for the upper part of the head, and the C3 dermatome covers the side of the face and back of the head.
What's in carotid sheath?
The carotid sheath plays an important role in head and neck anatomy and contains several vital structures, including the carotid artery, jugular vein, vagus nerve, and sympathetic plexus. It arises in the base of the neck and terminates at the skull base. It is derived from mesoderm.
What is subclavian artery?
The subclavian arteries lie just below the clavicles, providing blood supply to the bilateral upper extremities with contributions to the head and neck. The right subclavian artery derives from the brachiocephalic trunk, while the left subclavian artery originates directly from the aortic arch.
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 does the lateral thoracic artery supply?
Pectoral branches of the thoracoacromial and lateral thoracic arteries supply both the pectoralis major and minor muscles and must be identified during surgical dissection of the axilla. The lateral thoracic artery is of particular importance in surgery of the breast as it supplies the lateral mammary branches.
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.
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 is in the circle of Willis?
The Circle of Willis is the joining area of several arteries at the bottom (inferior) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the cerebrum.
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 does superior epigastric artery supply?
The superior epigastric artery is a terminal branch of the internal thoracic artery that contributes to the blood supply of the anterior abdominal wall. … Along its course, it gives several collateral branches that supply the muscles and the skin of the anterior abdominal wall.
What is Musculophrenic?
Definition of musculophrenic : supplying the muscles of the body wall and the diaphragm musculophrenic nerve musculophrenic blood vessel.
What does the Lima supply?
When the bilateral internal mammary artery (BIMA) is grafted in situ, the left internal mammary artery (LIMA) is generally used for the left descending artery (LAD) and the RIMA for the right coronary artery (RCA), or for the lateral wall, usually going through the transverse sinus. …
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 is transverse cervical artery?
The transverse cervical artery (transverse artery of neck or transversa colli artery) is an artery in the neck and a branch of the thyrocervical trunk, running at a higher level than the suprascapular artery.
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 causes deep cervical lymph nodes to swell?
Any infection or virus, including the common cold, can cause your lymph nodes to swell. Cancer can also cause lymph node inflammation. This includes blood cancer, such as leukemia and lymphoma.
Is supraclavicular lymph node deep or superficial?
[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?
Swelling and pain in the lymph nodes are signs of an infection and sometimes, a malignancy (a cancerous tumor). The swollen supraclavicular lymph nodes are easily felt as small tender lumps at the top of the collarbone.
What does C5 nerve innervate?
The muscles innervated by C5 are: Serratus Anterior, Deltoid, Ifraspinatus, Teres minor, Teres major, Pectoralis major, Supraspinatus, Biceps, Brachialis, Brachioradialis, Supinator.
