PSY 1012 Lecture Notes - Lecture 30: Peripheral Nervous System, Efferent Nerve Fiber, Central Nervous System
Document Summary
First neurotransmitter to be identified; found at the synapses between neurons and muscle cells; stimulates the skeletal muscles to contract but actually slows contractions in the heart muscle; involved in arousal, attention, memory, and controls muscle contractions. Excitatory or inhibitory; involved in sleep, mood, anxiety, and appetite. Major inhibitory neurotransmitter; involved in sleep and inhibits movement. Major excitatory neurotransmitter; involved in learning, memory, formation, nervous system development, and synaptic plasticity. Process by which neurotransmitters are taken back into the synaptic vesicles. Process by which the structure of a neurotransmitter is altered so it can no longer act on a receptor. The brain and spinal cord, controls the life sustaining functions, as well as thought, emotion, and behavior. The bundle neurons that serves two vital functions for the nervous system. Carries messages from the senses to the spinal cord. Carries messages from the spinal cord to the muscles and glands.
