physiology - Organisation of the Nervous System Flashcards
Ipsilateral
contralateral
- on same side of body or brain
- on opposite ‘’
Myelencephalon
contains…. function
medulla oblongata….
has nuclei that controls breathing and skeletal muscle tone
function of cerebellum
receives info from sensory systems, vestibular sys and muscles
THEN coordinates this info to produce smooth movements
function of pons
involved in sleep and arousal
function of Red Nucleus in midbrain
coordinates sensorimotor info
function of substancia nigria
makes dopamine and project to basal ganglia
periaqueductal grey matter function
involved with pain suppression due to high conc of endorphins
function of thalamus
interconnected nuclei get info from sensory systems and the pass on the info in sensory processing areas in cortex.
relay system and can influence almost whole brain
learning and memory
hypothalamus
made up of
control
functions
22 nuclei and pituitary gland
endocrine system and autonomic nervous system
releases hormones
regulated body temp and emotional response
controls appetite
The hemispheres are separated by
longitundinal fissure
why is it called grey matter
cortex has grey appearance since cells predominate in cortex
why is it called white matter
underneath the surface of cortex there are myelonated axons
The hemispheres are connected by
corpus callosum
Spinal cord functions:
Neuronal link between brain and PNS
spinal cord
spinal nerves
cns
pns
