Gross anatomy pt 1 Flashcards
two divisions of NS
central and peripheral
brain and spinal cord
central NS
everything besides the brain and spinal cord
peripheral NS
contain the sensory and motor nerves
PNS
- has afferent and efferent divisions
- voluntary control
- skeletal muscles and skin
- branch of PNS
somatic nervous system (SNS)
- visceral organs and glands
- involuntary control
- has afferent and efferent divisions
- branch of PNS
autonomic nervous system (ANS)
- prepares for fight or flight
- accelerates heart rate, constricts blood vessels, induces perspiration, mobilizes glucose
- part of ANS
sympathetic
- conserves energy
- slows heart rate
- sleeping and relaxing
- GI Tract for digestion
- part of ANS
parasympathetic
the ridge/hill landmark in brain
gyrus
groove/valley landmark in brain
sulcus
divides two hemispheres of the brain
longitudinal fissure
- fissure of rolando
- top and bottom (frontal and parietal)
central sulcus
- cuts temporal lobe from frontal and parietal
lateral sulcus
connected by the corpus callosum
cerebrum
personality, decision making, logic, intelligence, motor areas
frontal
- contains primary and association sensory areas
- spatial oraganization
parietal
- back of head
- vision
occipital
- bottom of cerebrum
- hearing
- language (wernickes)
temporal
- emotion
- memory
limbic
- frontal
- parietal
- occipital
- temporal
- limbic
telecephalon
- thalamus
- hypothalamus
- basal ganglion
diencephalon
sensory relay- gateway to cortex
thalamus
regulates autonomic and endocrine functions such as water balance, fat metabolism
hypothalamus
deep in the cerebrum
initiates motor activity
basal ganglion
