Ch 11: organization of nervous tissues Flashcards
Receiving sensory input
Monitor internal and external stimuli
Integrating information
The brain and spinal cord processes the sensory input and initiate responses
What are the three central nervous system’s that are on the midline?
Brain, brain stem, and spinal cord
What are the three peripheral nervous system?
Cranial nerves, spinal nerves, peripheral nerves
Sensory receptors of PNS
Endings of neurons specialize cells that detect temperature pain and etc
What is another name for sensory of PNS?
Afferent
What is another name of motor for PNS?
Efferent
What does sensory of PNS do?
- sensory: afferent *
Transmit action potential from receptors to central nervous system 
What does motor of PNS do?
- motor: efferent *
Transmit action potential from central nervous system to detect muscles glands
