Report Abuse. A lysosome is like the cleanup crew of the cell. One of its functions is the digestion of lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell. Lysosomes are also involved in the breakdown of organellesthat have outlived their usefulness. Source(s): My biology book :).
What is spinal muscular atrophy (SMA)? SMA is a rare genetic neuromuscular disease that affects the part of the nervous system that controls voluntary muscle movement. In spinal muscular atrophy, there is a loss of important cells in the spinal cord called motor neurons, which are essential for muscle strength and movement.
The supplementary motor area (SMA) is a part of the primate cerebral cortex that contributes to the control of movement.It is located on the midline surface of the hemisphere just in front of (anterior to) the primary motor cortex leg representation.In monkeys the SMA contains a rough map of the body.In humans the body map is not apparent.he role of the SMA was further substantiated by Cunnington et al. 2003, showing that SMA proper and pre-SMA are active prior to volitional movement or action, as well as the cingulate motor area (CMA) = anterior mid-cingulate cortex (aMCC).
