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.
This can be done in terms of the chemical elements present, or by molecular structure e.g., water, protein, fats (or lipids), hydroxyapatite (in bones), carbohydrates (such as glycogen and glucose) and DNA. In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc.
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.

Hydrostatic skeletons can be controlled by several different muscle types. Length can be adjusted by longitudinal muscle fibers parallel to the longitudinal axis. The muscle fibers may be found in continuous sheets or isolated bundles, and the diameter can be manipulated by three different muscle types: circular, radial, and transverse. [2]
Closeup of the trunk of an Asian elephant. Muscles provide the force to move a muscular hydrostat. Since muscles are only able to produce force by contracting and becoming shorter, different groups of muscles have to work against each other, with one group relaxing and lengthening as the other group provides the force by contracting.
Fibromuscular tissue is made up of fibrous tissue and muscular tissue. New vascularised connective tissue that forms in the process of wound healing is termed granulation tissue. [13] All of the special connective tissue types have been included as a subset of fascia in the fascial system, with blood and lymph classed as liquid fascia. [14] [15]
The skeletal muscles of the body typically come in seven different general shapes. This figure shows the human body with the major muscle groups labeled. The gross anatomy of a muscle is the most important indicator of its role in the body. One particularly important aspect of gross anatomy of muscles is pennation or lack thereof. In most ...
