In human anatomy, the common iliac veins are formed by the external iliac veins and internal iliac veins. The left and right common iliac veins come together in the abdomen at the level of the fifth lumbar vertebra, forming the inferior vena cava. They drain blood from the pelvis and lower limbs.
The external iliac veins are large veins that connect the femoral veins to the common iliac veins. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins.
The facial artery is a branch of the external carotid artery that supplies structures of the superficial face.
In the human body, the lateral thoracic artery is a blood vessel that supplies oxygenated blood to approximately one-third of the lateral structures of the thorax and breast.
The thyrohyoid muscle is a small skeletal muscle of the neck. Above, it attaches onto the greater cornu of the hyoid bone; below, it attaches onto the oblique line of the thyroid cartilage. It is innervated by fibres derived from the cervical spinal nerve 1 that run with the hypoglossal nerve to reach this muscle. The thyrohyoid muscle depresses the hyoid bone and elevates the larynx during swallowing. By controlling the position and shape of the larynx, it aids in making sound.
The foramen spinosum is a small open hole in the greater wing of the sphenoid bone that gives passage to the middle meningeal artery and vein, and the meningeal branch of the mandibular nerve.
In human anatomy, the superior epigastric artery is a terminal branch of the internal thoracic artery that provides arterial supply to the abdominal wall, and upper rectus abdominis muscle. It enters the rectus sheath to descend upon the inner surface of the rectus abdominis muscle. It ends by anastomosing with the inferior epigastric artery.
The thyrocervical trunk is a short artery of the neck. It arises from the subclavian artery, then promptly divides into its branches: the inferior thyroid artery, suprascapular artery, and (sometimes) the transverse cervical artery.
The right colic artery is an artery of the abdomen, a branch of the superior mesenteric artery supplying the ascending colon. It divides into two terminal branches - an ascending branch and a descending branch - which form anastomoses with the middle colic artery, and ileocolic artery (respectively).
The infraorbital artery is a small artery in the head that arises from the maxillary artery and passes through the inferior orbital fissure to enter the orbit, then passes forward along the floor of the orbit, finally exiting the orbit through the infraorbital foramen to reach the face.
The ligament of the head of the femur is a weak ligament located in the hip joint. It is triangular in shape and somewhat flattened. The ligament is implanted by its apex into the anterosuperior part of the fovea capitis femoris and its base is attached by two bands, one into either side of the acetabular notch, and between these bony attachments it blends with the transverse ligament.
The angular artery is an artery of the face. It is the terminal part of the facial artery. It ascends to the medial angle of the eye's orbit. It is accompanied by the angular vein. It ends by anastomosing with the dorsal nasal branch of the ophthalmic artery. It supplies the lacrimal sac, the orbicularis oculi muscle, and the outer side of the nose.
The internal iliac vein begins near the upper part of the greater sciatic foramen, passes upward behind and slightly medial to the internal iliac artery and, at the brim of the pelvis, joins with the external iliac vein to form the common iliac vein.
The short posterior ciliary arteries are a number of branches of the ophthalmic artery. They pass forward with the optic nerve to reach the eyeball, piercing the sclera around the entry of the optic nerve into the eyeball.
The artery to the ductus deferens is an artery in males that provides blood to the ductus deferens.
The deep circumflex iliac vein is formed by the union of the venae comitantes of the deep iliac circumflex artery. It drains venous blood from the walls of the iliac fossa. It empties into the external iliac vein about 2 cm superior to the inguinal ligament, just distal to where the inferior epigastric vein does so. The DCIV runs across the external iliac artery. It forms anastomoses with the iliolumbar vein, and lower two lumbar veins.
The anterolateral central arteries or lenticulostriate arteries are a group of small arteries mostly arising from the middle cerebral artery that enter the brain through the anterior perforated substance to provide arterial supply to parts of the basal ganglia. They are end arteries.
The thalamogeniculate artery is either a single artery or group of smaller arteries arising from the posterior cerebral artery. It is part of the posterolateral central arteries. It supplies parts of the thalamus.
The anterior auricular muscle, the smallest of the three auricular muscles, is thin and fan-shaped, and its fibers are pale and indistinct. It arises from the lateral edge of the epicranial aponeurosis, and its fibers converge to be inserted into a projection on the front of the helix.
The retroduodenal arteries are several small arteries which usually arise from the gastroduodenal artery posterior to the superior part of duodenum, but may also arise from the posterior superior pancreaticoduodenal artery. They are distributed to the superior part (I) and proximal portion of the descending part (II) of duodenum, as well as the bile duct. The arteries pass anterior to the retroduodenal segmant of the bile duct.
