brain Flashcards
what is in the hindbrain
Medulla oblongota, cerebellum and pons
what nerves come from medulla oblongota?
whats its function
CN’s 9-12
- HR
- respiration
whats cerebellum function
motor coordination, cognitive functions- temporal coordination and planning
what nerves come from pons
cranial nerves V, VI, VII, VIII
what nerves come from midbrain
III and IV
whats in the midbrain
- cerebral peduncles (fibers connecting forebrain to hindbrain- descending axons of upper motor neurons)
- corpora quadrigemina ( superior colliculi= visual tracking, coordination of head turning and eye movements, and inferior colliculi = sound location, focusing attention to auditory stimuli)
- substantia nigra (makes dopamine, damaged in parkinsons)
whats in the forebrain
- thalamus
- hypothalamus
- basal nuclei (basal ganglia)– fornix at top of caudate nucleus
- amygdala (at tail of caudate nucleus but not part of the basal ganglia)
- hippocampus (right before amygdala)
whats the thalamus do
-sensory relay for all afferents EXCEPT olfaction
whats the hypothalamus do
regulation
- body temp
- hunger
- thirst
- sexual activity
- endocrine
- visceral motor systems
whats the basal nuclei
part of forebreain
-collection of deep brain structures- modulate and integrate components of motor activity and cognitive functions. system depends on dopamine- affected by parkinsons disease
-caudate nucleus, putamen, and globus pallidus – slide 14
whats the amygdala function
lies at tail of caudate nucleus, not part of it tho functionally
-control of rage, aggression and sexuality
whats the hippocampus function
formation of new memories involvement, specifically episodic memories.
where are the primary motor/sensory cortexs?
primary motor is in the prefrontal cortex next to the central sulcus
where is the primary sensory cortex
next to central sulcus, in the parietal lobe
which lobes are the auditory and visual cortex in?
auditory= lateral of temporal lobe
visual=posterior area occipital lobe
