Tips. The pile squat is effective if you can achieve proper form and a complete range of motion. A lack of flexibility in the ankles will affect your form. To correct this, stand with your heels on two small blocks. The floor may limit your range of motion.
OTHER FORMS OF HYDROCEPHALUS. Hydrocephalus ex vacuo: dilatation of the cerebral ventricles due to loss of brain tissue. This is a common sequel of wasting brain diseases (leukodystrophies, multiple sclerosis, multiple strokes, Alzheimer's disease, Huntington's disease, etc.).
Exocytosis. Exocytosis is the reverse of endocytosis. And that is just as well. In 30 minutes an active cell like a macrophage (right) can endocytose an amount of plasma membrane equal to its complete plasma membrane. It restores the normal amount of plasma membrane. 2  Any molecules dissolved in the fluid contents of these vesicles are discharged into the extracellular fluid-this is called secretion. 3  Example: the various components of the extracellular matrix are secreted by exocytosis.
