coordinates swallowing, coughing, breathing and blood pressure
what does the pons control?
works with the medulla for maintenance of posture and regulation of breathing
what does the midbrain control?
control of eye movement and contains nuclei for auditory and visual systems
what is the function of the cerebellum?
coordination of movement, planning and executing movement, maintenance of posture and coordination of head and eye movement
what is the main role of the thalamus?
process almost all sensory information traveling to the cerebral cortex and almost all motor information coming from the cerebral cortex
what is the role of the hypothalamus?

what are the functions of the frontal lobe?
working memory and executive functions
what are the functions of the parietal lobe?
somatosensory and motor functions
what are the functions of the temporal lobe?
audition
what are the functions of the occipital lobe?
vision
what is the hippocampus involved in?
memory
what is the amygdala involved in?

what are glial cells and what is their function?
supporting cells for neurons that include oligodendocytes, astrocytes and microglia
what are the functions of astrocytes?
- supply metabolic fuel (lactic acid)
- synthesis neurotransmitters
- secrete trophic factors
- modulate cerebral blood flow
- help maintain extracellular K+
- help form blood brain barrier
what is a glioblastoma?
form of astrocytoma and more malignant form of brain cancer
