what is frontal lobe
control movement of voluntary muscles(e.g./ walking and speech), linked with intellectual activity and personality
what is temporal lobe
associated with vision and hearing, linked to memory and interpretation
parietal lobe
associated with touch, temperature, pain, pressure. linked to emotions and interpreting speech.
occipital lobe
associated with vision. linked to interpreting visual information
what does the thalamus do
relays sensory information received to cerebrum
what does the hypothalamus do
maintains homeostasis through hormone regulation, connected to the posterior pituitary through the nervous system and the anterior pituitary through releasing hormones
what does the cerebrum do and what do each of the sides do
responsible for thinking in the human brain;
right side is considered to be the side for visual patterns & spatial awareness
left side is considered to be the side for verbal skills and logical thought
what does corpus callosum do
allows both hemispheres to communicate with each other
what does the cerebellum do
controls fine motor control(muscles, balance, etc)
what does the pons do
passes information between the cerebellum and the medulla oblongata
what does the medulla oblongata do
connects the CNS with PNS
controls involuntary muscle movements
- breathing movements
- swallowing
- heart rate
controls autonomic nervous system (don’t need to think about)
motor axons cross here, results in right hemisphere controlling left side of body etc
what is the PNS split into
autonomic and sensory somatic nervous system
what does the autonomic nervous system control and what part of the brain controls it
parasympathetic and sympathetic system
medulla oblongata
parasympathetic nervous system what does it do
return to rest and digest
constricts bronchi, constricts pupils, stimulates digestive activity
sympathetic nervous system what does it do
fight or flight
secretion of epinephrine and norepinephrine
relaxes bronchi
inhibits salivation
dilates pupils
