biotech action

Can anyone give me an overview of biotechnology?

In particular, please prosthesis. Maybe a little on the nervous system. Oh, and how get muscle action of the brain transmitted to the muscle? I heard there is a chemical change of electric charge or something. Maybe a little on the brain would be nice too.

Wow, that's a lot of questions. I'll try to answer the how the muscle action is transmitted from the brain. Preproplanning of a specific movement began in the supplementary area (area 6) of the motor cortex. That receives input from the lymph thalamus, cerebellum and the base, until a precise program "(a specific set of muscle movement commands) is formed. This program is transmitted to their respective cells pyramid of the primary motor cortex. The primary motor cortex in area 4 of the frontal lobe of the brain, neurons that are really starting the momentum that controls movement. The drive down through the pyramidal tract, near the level crossing of the midbrain and pons. It continues its transmission in the spinal cord to corticalspinal through the lateral and ventral pathways until it reaches the alpha motor neurons, the neuron contacts the muscle fibers. Alpha motor neurons outputs of the spinal cord and extends to the neuromuscular end plate, where it releases acetylcholine nicotinic receptors opens the muscle fiber. A generally alpha motor neuron commands a group of muscle fibers. Open nicotinic receptors increases the flow of sodium ions into the muscle, producing a final depolarization potential plate. The end plate potential travels through the muscle fiber membrane in the T-tubules to the sarcoplasmic reticulum, where it opens dependent calcium channel voltage, which in turn releases intracellular calcium initiates muscle contraction.
