bipolar neurons
are found in some special sensory organs such as olfactory, muscosa, eye, ear
Mutipolar neurons
most abundant in body
Unipolar neurons
found mainly in the PNS
Unipolar neurons
common only in dorsal root ganglua of the spinal cord and sensory ganglia of cranial nerves
Fore brain
cerebral hemisphere diencephalon
Fore brain
thalamus and hypothalamus and pituitary gland
Hind brain
medulla oblongata and pons
Spinal cord
caudal continuation of the medulla oblongata
Sensory signals
are carried from sensory receptors through the PNS into the CNS
Motor signals
are carried away fro, the CNS and through the PNS to the effectors, which are muscles and glands
somatic
outer body
visceral
mainly inside the body
spinal nerves
nerves of PNS
mixed
nerves that contain sensory and motor axons are called
plexuses
. The appendages are supplied by braid like arrangements of nerves called
Spinal nerves
supply sensory abd motor fibers
Autonomic nervous system
a system of motor neurons that innervate the smooth muscle, cardiac, and glands of the body
Autonomic nervous system
the general visceral motor division of the peripheral nervous system are in what system
Sympathetic
prepares the body for fight or flight
Parasympathetic
are active during rest and digest
