aka cerebral aqueduct, tectum & tegmentum
t & t
2 parts of the metencephalon aka 4th ventricle
pons and cerebellum
part of the myelencephalon
medulla, (reticular formation) - keeps us physiologically alive

abstract thought, regulate movements, make decisions
what disease is caused by a degeneration of some of the parts of the BASAL GANGLIA
Parkinson's is caused by the degeneration of the dopamine neurons in the caudate nucleus and putamen
3 parts of the basal ganglia
-caudate nucleus
-globus pallidus

relay station for sensory info
what does the hypothalamus do?
controls the autonomic nervous system, hormonal controls - 4 Fs

-periaqueductal gray matter
-substancia nigra
2 colors
2 parts of tectum and function
-superior colliculi - vision
-inferior colliculi - hearing
see, hear
what does cerebellum mean and what does it do
"little brain" - fine motor coordination

how many lumbar
the names of the 2 fused spinal structures
coccyx, sacral
what does the dorsal root do?
spinal root that contains incoming (afferent) sensory fibers
what does the ventral root do?
spinal root containing outgoing (efferent) motor fibers
what does the central nervous system include
brain, spinal cord
what are the divisions in the peripheral nervous system
somatic, autonomic (sympathetic, parasympathetic)
2 main, 2 branches
what does the sympathetic autonomic system do
what does the parasympathetic autonomic system do
what is phagocytosis
cells that engulf dead neurons

oligodendrocytes in the pns, schwann cells in cns
afferent neurons are..
interneurons do what?
relay messages between sensory and motor neurons
efferent neurons are...
what is the history of neuron doctrine?
nervous system is made up of discrete cells called neurons
at rest, the inside of a cell is ____ compared to outside
what is diffusion
movement of molecules to areas of low concentration from areas of higher concentration
what is electrostatic pressure
"opposites attract" - attractive force between atomic particles charged with opposite signs or the repulsive force between 2 atomic particles charged with same sign
what is exocytosis
when the vesicles migrate, fuse, and deposit contents into synaptic cleft
what is an epsp?
