ANATOMY OF THE NERVOUS SYSTEM
nervous system
central nervous system (CNS)
peripheral nervous system (PNS)
somatic nervous system
autonomic nervous system
describe location
ventral
dorsal
anterior
posterior
superior
inferior
lateral
spinal cord
communicates with sense organs & muscles
Bell-Magendie law
entering dorsal roots
carry sensory info
exiting ventral roots
carry motor info
cell bodies of sensory neurons
dorsal root ganglia
grey matter
center of spinal cord
white matter
carries info from grey matter to brain/other areas of spinal cord
autonomic nervous system
sympathetic nervous system
prepares organs for rigorous acitivites
parasympathetic nervous system
facilitate nonemergency response
sends & receive messages to regulate automatic behaviours of body
brain structure
hindbrain
medulla
cranial nerves
pons
reticular formation
descending portion
ascending portion
raphe system
cerebellum
midbrain
tectum
superior colliculus & inferior colliculus
tegmentum
substantia nigra
forebrain
cerebral cortex
limbic system
olfactory bulb
hypothalamus

amygdala
cingulate gyrus
subcortical regions
thalamus
hypothalamus
pituitary gland
basal ganglia
basal forebrain
nucleus basalis
hippocampus
central canal
venricles
cerebrospinal fluid (CSF)
meninges
cerebral cortex
most prominent part of brain
divided into 2 halves
joined by 2 bundles of axons
corpus callosum
anterior commissure
organisation
6 distinct laminae
cells of cortex divided into columns
divided into 4 lobes
4 lobes
occipital lobe
highly responsible for visual input
parietal lobe
contains postcentral gyrus
essential for spatial info & numerical info
temporal lobe
auditory info & processing spoken language
Kluver-Bucy syndrome
temporal lobe damage
frontal lobe
precentral gyrus
control fine motor movement
prefrontal cortex
responsible for
abstract thinking & planning
ability to remember recent events & info
