BASIC NEURON PHYSIOLOGY - Ben Best.
Nervous system anatomy and physiology The nervous system is involved in nearly everything we do - from how we see, to how we walk and talk. The nervous system is divided into the central nervous system, so the brain and the spinal cord, and the peripheral nervous system, which is further divided into the somatic and the autonomic nervous systems.
The upper motor neuron has its cell body in the cerebral cortex and synapses on a cell in the gray matter of the spinal cord. The lower motor neuron is that cell in the gray matter of the spinal cord and its axon extends into the periphery where it synapses with a skeletal muscle in a neuromuscular junction.

Neuron, also called nerve cell, basic cell of the nervous system in vertebrates and most invertebrates from the level of the cnidarians (e.g., corals, jellyfish) upward.A typical neuron has a cell body containing a nucleus and two or more long fibres. Impulses are carried along one or more of these fibres, called dendrites, to the cell body; in higher nervous systems, only one fibre, the axon.
Major Parts Of The Nervous System. The central nervous system (CNS) comprises of the brain and spinal cord. According to (Hull, 2011, p. 200) 'it has three functions: sensory, integrative and motor.'.
