The dorsal scapular nerve is a branch of the brachial plexus. It supplies rhomboid major muscle, rhomboid minor muscle, and levator scapulae muscle. It causes the scapula to be moved medially towards the vertebral column. Dorsal scapular nerve syndrome can cause a winged scapula, with pain and limited motion.
In human anatomy, the subclavian arteries are paired major arteries of the upper thorax, below the clavicle. They receive blood from the aortic arch. The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. On the left side of the body, the subclavian comes directly off the aortic arch, while on the right side it arises from the relatively short brachiocephalic artery when it bifurcates into the subclavian and the right common carotid artery.
The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart. The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart. The pulmonary veins are part of the pulmonary circulation.
The rhomboid major is a skeletal muscle on the back that connects the scapula with the vertebrae of the spinal column. In human anatomy, it acts together with the rhomboid minor to keep the scapula pressed against thoracic wall and to retract the scapula toward the vertebral column.
The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
The small saphenous vein, is a relatively large superficial vein of the posterior leg.
The subscapular artery, the largest branch of the axillary artery, arises from the third part of the axillary artery at the lower border of the subscapularis muscle, which it follows to the inferior angle of the scapula, where it anastomoses with the lateral thoracic and intercostal arteries, and with the descending branch of the dorsal scapular artery, and ends in the neighboring muscles.
The circumflex scapular artery is a branch of the subscapular artery and part of the scapular anastomoses.
The transverse cervical artery is an artery in the neck and a branch of the thyrocervical trunk, running at a higher level than the suprascapular artery.
Dorsal scapular may refer to:
The suprascapular artery is a branch of the thyrocervical trunk on the neck.
The vitelline veins are veins that drain blood from the yolk sac and the gut tube during gestation.
The common cardinal veins, also known as the ducts of Cuvier, are veins that drain into the sinus venosus during prenatal development. These drain an anterior cardinal vein and a posterior cardinal vein on each side. Each of the ducts of Cuvier receives an ascending vein. The ascending veins return the blood from the parietes of the trunk and from the Wolffian bodies, and are called cardinal veins. Part of the left common cardinal vein persists after birth to form the coronary sinus.
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:
The posterior intercostal veins are veins that drain the intercostal spaces posteriorly. They run with their corresponding posterior intercostal artery on the underside of the rib, the vein superior to the artery. Each vein also gives off a dorsal branch that drains blood from the muscles of the back.
In human anatomy, the dorsal veins of the penis comprise the superficial dorsal vein of the penis and the deep dorsal vein of the penis.
The dorsal metatarsal veins are veins which drain the metatarsus of the foot.
The deep dorsal vein of clitoris is a vein which drains to the vesical plexus.
The following outline is provided as an overview of and topical guide to human anatomy:
The dorsal lingual veins are veins which drain the tongue.
