Parts of the brain Flashcards
(20 cards)
What does the parietal lobe do?
body sensations
What does the occipital lobe do?
vision
What does the temporal lobe do?
hearing, advanced visual processing
What does the frontal lobe do?
planning of movements, recent memory, some aspects of emotions
What does the post central gyrus do?
primary somatosensory cortex
What does the pre central gyrus do?
primary motor cortex
What is the medulla?
an extension of the spinal cord into the skull - retains autonomic nervous system (heart rate, breathing)
relays sensory to and motor info from brain to spain
What are the pons?
large bulge in brain stem
pons = bridge. relays info from the cerebral cortex to the cerebellum
sleep & arousal
What is the cerebellum involved in?
“little brain”
contains 2 hemispheres
used for control of fine detailed motor movement & control. Constitutes only 10% of brain mass but has 50% of brain cells.
What does the cerebrum do?
contains the cerebral cortex
contains hippocampus, basal ganglia, olfactory bulb etc.
with assistance of the cerebellum, controls are voluntary actions of the body
What is the limbic system?
located on both sides of the thalamus, under the cerebrum
supports a variety of functions including emotion, behaviour, motivation, long-term memory & olfaction
emotional life
what is in and what does it do - basal ganglia
thalamus, caudate nucleus, putamen
control of voluntary movements, habits, procedural learning
What is the dorsal surface in the midbrain called
tectum
What is the periqueductal grey in the midbrain involved in
defence mechanisms
Discuss midbrain
midbrain = superior colliculus receives direct info from eye, inferior colliculus from ear > allows quick responses from stimuli & relays info to thalamus
What is thalamus
known as sensory and motor relay area
What is hypothalamus
involved in survival mechanisms
What is pituitary gland
release hormones into bloodstream following instruction from hypothalamus
What is hippocampus
looped, looks like seahorse - involved in memory
works opposite amygdala to stop release of stress
what are the caudate nucleus, putamen and globus pallidus known as
striatum
