Cavernous hemangioma, also called cavernous angioma, venous malformation, or cavernoma, [1] [2] is a type of venous malformation due to endothelial dysmorphogenesis from a lesion which is present at birth. A cavernoma in the brain is called a cerebral cavernous malformation or CCM.
These formations are made of a sponge-like tissue containing trabeculae, irregular blood-filled spaces lined by endothelium and separated by septum of the penis. [ 7 ] [ 8 ] The male anatomy has no vestibular bulbs , but instead a corpus spongiosum , a smaller region of erectile tissue along the bottom of the penis, which contains the urethra ...
Cerebral cavernous malformation (CCM) is a cavernous hemangioma that arises in the central nervous system.It can be considered to be a variant of hemangioma, and is characterized by grossly large dilated blood vessels and large vascular channels, less well circumscribed, and more involved with deep structures, with a single layer of endothelium and an absence of neuronal tissue within the lesions.

The vermis is the unpaired, median portion of the cerebellum that connects the two hemispheres. [9] Both the vermis and the hemispheres are composed of lobules formed by groups of folia. There are nine lobules of the vermis: lingula, central lobule, culmen, clivus, folium of the vermis, tuber, pyramid, uvula and nodule. [9]
One way Samuel likes to think about organizing the muscle groups of the body is by dividing them into two groups: The main muscles and accessory muscles. Major Muscle Groups Your main muscles are ...
The bulbospongiosus muscles (in older texts bulbocavernosus and, for female muscle, constrictor cunni) are a subgroup of the superficial muscles of the perineum. [1] They have a slightly different origin, insertion and function in males and females. In males, these muscles cover the bulb of the penis, while in females, they cover the vestibular ...
The medulla can be thought of as being in two parts: an upper open part or superior part where the dorsal surface of the medulla is formed by the fourth ventricle. a lower closed part or inferior part where the fourth ventricle has narrowed at the obex in the caudal medulla, and surrounds part of the central canal.
