Brain Stem
Midbrain: visual/auditory info
Pons: somatic/visceral motor control
Medulla oblongota: relay info and autonomic function
Interneurons
divergence
convergence
serial processing
parallel processing
reverberation
Cerebrospinal Fluid
cushions structures
transports nutrients
supports brain
produced by ependymal cells in choroid plexus (inside ventricles)
Nerve Plexus
lumbar plexus
brachial plexus
cervical plexus
sacral plexus
Cranial Meninges
Arachnoid mater: weblike and non-conforming
*ventricles are lined by ependymal cells that produce cerebrospinal fluid
Dura Mater: fused to periosteum of cranial bones
Dural folds
Subdural space
Pia Mater: in direct contact with cerebral cortex
Reflexes
tendon
withdrawl
plantar
babinski
Organization
PNS
afferent (sensory)
efferent (motor)
autonomic
somatic
CNS
enteric nervous system
Spinal Nerve Anatomy
Endoneurium
Perineurium
Epineurium
Neuron Functional classification
Interneurons: between
sensory & motor neurons
Motor Neurons: cell body in
CNS & axon processes
extend to peripheral effectors
Sensory Neurons: unipolar neurons with
cell body in sensory ganglia and
processes extending to CNS
somatic sensory neurons
visceral sensory neurons
