The efferent division of the peripheral nervous system carries out the motor commands that are sent from the central nervous system. These commands or signals are then sent directly through the nerve fibers of the peripheral nervous system to the ta Continue Reading...
What happens is this over production of neurons results in a kind or "pre-programmed 'suicide' mechanism called apoptosis" (Marino, 2010). So if the brain kills off these neurons on purpose, what happens to the dead neurons? Journalist Melissa Marin Continue Reading...
Parkinson's Disease The human central nervous system is a miraculously designed functional piece of our bodies that helps us conduct the most essential tasks to help in our survival. It is therefore very important to investigate and understand how t Continue Reading...
These indications then proceed to the neuromuscular connections of skeletal muscles. From there, acetylcholine is released from the axon terminal knobs of alpha motor neurons and received by postsynaptic receptors of muscles, thereby communicating t Continue Reading...
