SL8 Flashcards
In the CNS what is a group of axons travelling together called
tract, pathway or comissure
what is a nuclei/ganglia and what is the difference
they are a group of similar function neurons that cluster together, in the CNS this is called Nuclei and in the PNS this is the ganglia
what makes up the hindbrain
pons, medulla oblongoata and the cerebellum
in the cerebral hemispheres describe the 3 layers of the brain
- cerebral cortex: superficial grey matter
- white matter: deep tracts of myelinated axons
- subcortical nuclei: grey matter that is deep to white matter
what is the difference between grey and white matter
grey matte is cell bodies while white matter is myelinated axons
what connects the lef tand right hemisphere and what is mainly comprised of
this is corpus collosume, it is made of a large bundle of axons
what parts make up the cerebral cortex and what does it do
-frontal, perital, occipital and temporal
-site of complex integration of info
what does sucortical neucli do
it is important for controlling movement, posture and complex aspects of behaviour
what parts of the brain make up the limbic system and what is its purpose
-frontal, temporal, hypothalamus, thalamus and the pathways that connect them
-learning, emotional experience, behaviour, visceral/endocrine function
what does the thalamus do
-integration center for most inputs going to the cortex
-arousal, focusing attention and filtering extraneous info
what does the hypothalmus do
master comman center for neural-endocrine codination, as well it controls the pituitary gland
what does the epithamlus do
contains the pineal gland which helps with your circadian rhythm (realise melatonin)
