ipselateral means
on the same side (of the midline)
motor output leaves the spinal cord through the
ventral roots
a nerve is ____ and is located in the ___ nervous system
where dorsal and ventral roots meet; peripheral
dorsal roots are responsible for
somatosensory input
spinal nerves exit the spinal cord through
notches in each vertebra
afferent neurons carry info ___ the CNS and efferent carry info ____ the CNS
afferent = towards; efferent = away
somatosensory neurons are considered
afferent
efferent neurons innervate
muscles and glands

pia mater
what is the role of the choroid plexus?
makes CSF
the CNS develops from which primary developmental layer?
the ectoderm (same as skin)
how many spinal nerve pairs are there?
31
what is the role of the pons
attention/arousal; communication of info between cerebellum and ctx
what is the metencephanlon
pons and cerebellum
what does the tegmentum contian?
the snr (reward/movement) VTA (reward) PAG (pain control) also involved in eye movement, arousal, aud/visual relay
what is a general role of the parietal lobe?
somatosensation
what happens when you damage the insula?
cessation of drug taking behavior
a lissencephalic brain would not have
folding
what is the role of the mamilary bodies?
declaritive memory, integration of emotion with semantic info
