Autonomic nervous system: involuntary muscles and internal organs, b. maintaining homeostasis a. i. a. ii. Glia cells: serve supportive and protective functions, helping neurons to do their work, also supply oxygen and nutrients to neurons, remove dead cells and germs and importantly, serve as protective insulation around axons of neurons. Tract: nerves that are entirely within the brain and spinal cord (i. e. , the cns) Receptor --> sensory neuron --> integration center --> motor neuron --> effector. Transmission of pain o o o o o. Involves release of neurotransmitters, binding with receptors that excite or inhibit activity of postsynaptic cell. Psychology 100 online lesson 5 o o o. Amines: dopamine, epinephrine (energy), norepinephrine, serotonin (mood) and.
