The vitreous humor is a transparent, colorless, gel-like substance that fills the cavity of the eyeball. The front of the vitreous body is: the lens, the zonular ligament and the ciliary processes, and the back and sides are the retina.
The ductus deferens (ductus deferens), a paired organ, is a direct extension of the duct of the epididymis and terminates at the fusion site with the in vivo duct of the seminal vesicle.
The spine (vertebral column, columna vertebralis) is formed by 33-34 vertebrae, of which 7 cervical, 12 thoracic, 5 lumbar. Five sacral vertebrae fuse, forming a single bone - the sacrum (sacrum). The coccyx consists of 3-5 coccyx vertebrae.
Vertebra has a body and an arc. The vertebral body (corpus vertebrae) faces anteriorly and serves as its supporting part. The arc of the vertebra (areus vertebrae) connects from behind with the vertebral body with the legs of the vertebrae (pedunculi areus vertebrae).
Isolate the superficial and deep veins of the upper limb. They are connected by a large number of anastomoses and have numerous valves. Surface (subcutaneous) veins are more developed than deep veins (especially on the back of the hand).
The common iliac vein (v. Iliaca communis) is a large valveless vessel. It is formed at the level of the sacroiliac joint with the fusion of the internal and external iliac veins.
The veins of the lower limb are divided into superficial and deep. Superficial veins of the lower limb. The rear digital toes of the foot (ww. Digitales dorsales pedis) exit the venous plexuses of the fingers and flow into the posterior venous arch of the foot (arcus venosus dorsalis pedis).
The internal jugular vein (v. Jugularis interna) is a large vessel into which blood, from the head and neck, from the areas corresponding to the branching of the external and internal carotid and vertebral arteries, is collected, as well as into the external jugular vein.
Given the structure of the walls, there are two types of veins: the muscle and the muscle. The veins of the jawless type are the veins of the hard and soft meninges, the retina of the eye, bones, spleen and other organs of the immune system.
Outer nose. The number of cartilage of the nose varies, often their number is less than usual. In 20% of cases in the back of the septum there are right and left vesicular-nasal cartilages. The size and shape of the nose, the configuration of the nostrils are very variable.
Among violations of kidney development, there are anomalies due to the number. There is an additional kidney, which is formed from any side and lies below the normal kidney.
In the abdominal cavity and in the pelvic cavity there are various vegetative nerve plexuses of the largest size, consisting of vegetative nodes and bundles of nerve fibers connecting them.
The vagina (vagina, s.colpos) - an unpaired hollow organ shaped like a tube, is located in the cavity of the small pelvis and extends from the uterus to the genital gaps. At the bottom of the vagina passes through the urogenital diaphragm.
