Document Summary
Responsible for voluntary motor (movement) and reflex motor control. Single presynaptic neuron which directly signals to muscle. It will happen whether you want it to or not. Aggregation of neuron cell bodies outside of cns (spinal cord/brain) Preganglionic neuron > postganglionic neuron > effector organ. Normal physiologic response at rest (gut motility, etc) S and ps actions oppose one another. Anatomic regions can be mapped to function. Evolution > increase in forebrain size and complexity. Maps are specific but can be disproportionate by body system represented. A device such as a pattern of letters, ideas, or associations that assists in remembering something. Aiding or designing to aif the memboru. Create a mnemonic to help you remember regions or functions of the brain/brain stem from front to back. Contains neurons cell bodies, dendrites and fibers (neuropil) In the brain - grey matter surrounds white matter. Grey matter is central with surrounding white matter.
