individual cells in the nervous system that receive, integrate and transmit information.
soma (cell body)
contains the nucleus and chemical machinery common to most cells. The bulbous end of a neuron.
receives information and from other cells
thin fiber that transmits information away from the soma to other cells.
speeds up the transmition of information on the axons
clump at the end of the axon that secretes chemicals called neurotransmitters
a junction at the end of the axon that secretes neurotransmitters
the stable, negative charge of a neuron before action potential
what floods neuron in order to change its charge to positive
brief change in the neuron's charge that travels along the axon. They are all the same size; it is their rate of firing that changes.
the neurotransmitter between neurons and volutnary muscles. only one at muscular junction
controls voluntary movement and plays a large role in reward systems of the brain
widely distributed inhibitory transmitter that also helps regulate sleep, anxiety, and arousal
motory output that goes through the ventral
front of the spinal code
incoming sensory input goes through the dorsal
back of the spinal cord
part of the brain that handles basic, fundamental life actions
part of the hindbrain that organizes sensory info, but mainly guides movement, motor skills, balance
part of hindbrain that regualtes unconcious functions like breathing and circulation
Network of nerurons. houses the dopamine system, integrates sensory info, alertness, arousal, eye coordination.
located in the midbrain. big player in sleep and arousal
meticular (activating) formation
midbrain muscle reflexes, pain perception, sleep, arousal
motor neural control center
part of the forebrain through which the sensory information (not smell) pass through to reach the cerebral cortex
part of the forebrain responsible for meeting reguating basic bodily needs. Homeostasis and pituitary gland.
part of the limbic system involved in learning and memory
system involved in emotional experience and expression.
touch, body sensory, touch cortex
muscle movement cortex
structure that connects the two halves of the brain
hemisphere of the brain associtaed with verbal processing
hemisphere of the brain associated with nonverbal processing
