parts of the brain Flashcards
pons
bridge between medulla and other parts of the brain
allows sleeping and dreaming
reticular formation
made of nuclei: clusters of neurons
regulates sleep and waking up
cerebellum
allows motor control
medulla
controls reflexes like breathing, heart rate
essential for life! damage = death
substantia niagra
produces dopamine
allows fluid movements and starting/stopping
basal ganglia
allows voluntary control in learned tasks
pituitary control
controls growth, stress, etc. through hormones
amygdala
controls fear and related behaviours
hippocampus
retains short-term memory until it’s stored elsewhere
thalamus
integrates information that allows us to associate things
relays visual and auditory information to the cortex
hypothalamus
regulates motivation and basic needs through endocrine system
cerebral cortex
controls complex functions like thought and language
sensory cortex
info from sensory nerves
motor cortex
info from motor nerves
association cortex
involved in higher levels of thinking
frontal lobe
intellectual thinking and relationships
voluntary movement controlled by primary motor strip
occipital lobe
for vision, located on back of the head
parietal lobe
top of the brain somatosensory strip that allows sensation
allows spatial awareness and hand-eye coordination
pre-frontal lobe
allows planning, morality, and short-term memory
temporal lobe
allows auditory processing and complex visual processing like facial recognition
contains wernicke’s area and broca’s area for language understanding and speech respectively
glia
cells that make up nervous system other than neurons
astrocytes
makes up blood brain barrier that heals and allows brain communication
microglia
removes dead cells to prevent infections
oligodendroglia
provides myelin that insulates neurons and speeds up neural transmissions
