Intro to Neuroscience Flashcards
(31 cards)
any or all sciences that study the structure and function of the nervous system and brain
neuroscience
what is the primary roll of the nervous system
communicate and excite other cells
receive afferent/sensory information
dendrites
body
soma
helps increase speed of signals due to gaps and also helps protect the axon
myeline sheath
motor/behavior output
axon
skipping of signal along myeline sheath
saltatory conduction
cranial nerves CNS or PNS?
all are peripheral except olfactory
organization of the CNS in order of complexity in both structure and function
- spinal cord
- medulla
- pons
- midbrain
- cerebellum
- diencephalon
- cerebral hemispheres
what are the 3 meninges
dura matter, arachnoid matter, pia matter matter
is dorsal root sensory or motor
sensory
is ventral root sensory or motor
motor
brainstem stroke can lead to a syndrome in which you cannot speak or move, you can only move your eyes
locked in syndrome
the nervous system has a lot of overlap to make sure we can still function and not lose everything if there is an injury to the nervous system
redundancy
what are the 5 lobes of the cerebral hemisphere
frontal, parietal, occipital, temporal, insula
abstract thoughts, explicit memory, mood, motivation, foresight and planning, decision making, emotional control, social judgement, voluntary motor control, speech production
frontal lobe
taste, pain, visceral sensation, consciousness, emotion and empathy, cardiovascular homeostasis
insula
taste, somatic sensation, sensory integration, visual processing, spatial perception, language processing, numerical awareness
parietal lobe
visual awareness and visual processing
occipital lobe
hearing, smell, emotion, learning, language comprehension, memory consolidation, verbal memory, visual and auditory memory, language
temporal lobe
think receiving/processing
gray matter
neuronal cell bodies, ganglia in PNS, nuclei in CNS, brain (cortex and subcortical gray)
gray matter
think sending/transmitters
white matter
axons, myelinated, CNS tracts, PNS nerves, brain, internal capsule, corone radiata
white matter
