The NS Parts Flashcards
This system includes sensory nerves and motor nerves
PNS
This is a part of the PNS that regulates nonconscious or automatic functions
ANS
This is a branch of the ANS that is activated during emotional arousal by a release of epinephrine and norepinephrine from adrenal glands
sympathetic NS
This is a branch of the ANS that does fight or flight reaction
sympathetic branch
This is a branch of the ANS that balances the actions of the opposing branch by opposing opposite effects
this does normal maintenance
parasympathetic branch (primarily cholinergic)
What are the 3 major divisions of the human brain
hindbrain
midbrain
forebrain
This is a member of the hindbrain and is located above the spinal cord.
this is responsible for the regulation of basic life functions
Medulla Oblongata (Hindbrain)
This part of the hindbrain controls breathing, HR,vomiting,swallowing,BP and digestive processes
if toxic levels are met the vomit center is triggered to purge the body
medulla oblongata (hindbrain)
This is a member of the hindbrain and controls sleep and wakefulness
pons
this is apart of the pons and is responsible for alertness and arousal
reticular activating system
this is a part of the hindbrain and is used for motor control such as balance, coordination, and speech
cerebellum
(major target of alc)
what are the 4 parts of the midbrain
inferior colliculi
superior colliculi
susbtantia Nigra
ventral tegmental system
this is a part of the midbrain that is the auditory system
inferior colliculi
this is a part of the midbrain that is the localization of visual stimuli
superior colliculi
this is a part of the midbrain that produces dopamine that is transported through the motor pathway
ex. Parkinson’s disease (less and less of dopamine available)
substantial Nigra
this is a part of the midbrain that has dopamine neurons involved in reward
ventral tegmental area
this is a part of the forebrain and is the relay station that receives incoming sensory stimuli and relays info to the brain
thalamus (forebrain)
this is a part of the forebrain and is used for motivation of behavior.
it also regulates eating,drinking, body temp,aggression and sexual behavior
hypothalamus
this is the system found in the forebrain
limbic system
This is found in the limbic system of the forebrain and mediates aggression fear and emotional experiences
amygdala
This is found in the limbic system of the forebrain and is used for memory storage
hippocampus
This is found in the limbic system of the forebrain and has three parts that are important for motor movement
basal ganglia
(caudate nucleus, putamen, and globus pallidus)
What are the 3 main parts of the basal ganglia responsible for motor movement
caudate nucleus, putamen, and globus pallidus
This lobe is responsible for visual projection (back of the brain)
occipital lobe
this lobe is responsible for auditory stimulation (ex. language)
temporal lobe
this lobe is responsible for the initiation of movement
involved in emotionality, intelligence and personality
frontal lobe
his lobe is responsible for tactile stimuli and body sensations
parietal lobe
