system that receiving signals from and sending commands
to different areas of the body also known as communication system
nervous system

the 2 major division of nervous system
Central nervous system and peripheral nervous system
carries information about the different
tissues of the body to the CNS and delivers commands from the
CNS to other body tissues that alter body activities.
PNS or peripheral nervous system
composed of sensory neurons, Responsible for sensation
sensory division
-Composed of motor neurons,responsible for response
motor division
a motor division system that involves voluntary movement
Somatic
a motor division system that involves involuntary movements
autonomic
responsible for generating and spreading action potentials
neurons
the main body of the neurons.Has organelles like nucleus nucleoulus,er,golgi apparatus
cell body
packages the proteins in vesicles
golgi aparatus
group of cell bodies in CNS
nuclei
group of cell bodies in PNS
ganglia
Short branched extensions that received the action potential and relay it to the body
dendrites
-a long extension from the body that transmits action potential to other cells
axon
