SET 1
the nervous system
• Master control
• Has three overlapping functions
• Sensory receptors
• monitor inside and outside the body
• from PNS to CNS
• Processes and interprets sensory input
• Makes decisions - integration
• Dictates a response by activating effector organs
• Response
• Muscles
• Glands
• From CNS to PNS
1. sensory input
2.integration
3. motor output
central nervous system
brain (gray matter)and spinal cord (white matter)
integrating and command center
gray matter
in the spinal cord
• H-shaped region - surrounds central cavity
• Cell bodies are clustered in the gray matter
• Nucleus vs. ganglia

white matter
in the spinal cord
• External to gray matter
• No neuronal cell bodies, but millions of axons
• Myelin sheath - white color
• Consists of axons running between different parts of the
CNS
• Tracts - bundles of axons traveling to similar
destinations
• vs. nerve
neuronal regeneration
• Neural injuries may cause permanent dysfunction
• If axons alone are destroyed, cells bodies often
survive and the axons may regenerate
• PNS—macrophages invade and destroy axon distal
to the injury
• Axon filaments grow peripherally from injured site
• Partial recovery is sometimes possible
• CNS—neuroglia never form bands to guide regrowing
axons and may hinder axon growth with
growth-inhibiting chemicals
• No effective regeneration after injury to the spinal
cord and brain
peripheral nervous system
outside the CNS
nerves from brain and spinal cord
