The Human Nervous System Flashcards
What does the central nervous system consist of
the brain and the spinal cord
what is the central nervous system function
to coordinate a body response to external stimulus
what is the pathway of the human nervous system (i.e input process output)
Receptor –> CNS –> Effectpr
what are receptors
gland or muscle cell that detect a change in/outside your body
what do receptors detect
stimulus
what are effectors
the movement of muscles or hormone release as a result of stimulus
what is the thin tube called that runs through all neurones
the axon
what are the 3 neurones called
sensory
motor
relay
what do all neurones function as
transmitters for electrical impulses throughout the nervous system
what does the sensory neurone function as
transmitter of electrical impulses from receptor to CNS
what does the motor neurone function as
transmitter of electrical impulses from CNS to effectors
what does the relay neurone function as
connect system.
transmit electrical impulses through CNS from sensory to motor
What does the CNS act as for the whole system
coordinator
