Brain Structures & Functions Flashcards
Pons
1/3 components of brain stem, functions are sleep, breathing, taste, eye movement
Medulla
lower part of brainstem, functions are heart rate & breathing
Thalamus
Top of brain stem, Relay function: receiving/processing info from sensory receptors & relaying to appropriate structure in cortex
Hypothalamus
Cluster of neurons that sits below thalamus, function is body temperature, hunger/ thirst, sleep
Amygdala
in temporal lobes, process emotions and memories
Hippocampus
in medial temporal cortex, formation of memories
Broca’s Area
in frontal lobe of ONE hemisphere (usually L), controls speech production
Wernicke’s Area
controls written and spoken language
Basal Ganglia
fine tune voluntary movements, memory, eye movements, motivation
Cerebellum
planning & movement, damage can effect language/ decision making
Prefrontal Cortex
front of frontal lobe, planning, memory, personality, decision making, & emotional reactions
Corpus Callosum
thick layer of neural fibers that connects the two hemispheres of the brain
3 structures that make up brain stem
medulla, pons, and midbrain
4 lobes of the cerebral cortex
frontal, parietal, temporal, & occipital
Largest lobe of brain
Frontal
Parietal Lobe
sensory information and movement
Occipital Lobe
visual processing
Hills and Valleys of Cerebral Cortex
hills= gyrus, valleys= sulcus
Temporal Lobes
2 on either side, process sound, L hemisphere usually processes speech
Brain Stem
base of cerebrum, regulates reflexes (heart rate, breathing), relays info from brain to spinal cord
