brain pt1 Flashcards
principal and most anterior part of the brain
cerebrum
part of the brain at the back of the skull
cerebellum
ridge on the brain
gyrus/gyri
indentation or depression on the brain
sulcus/sulci
separates the human brain into two hemispheres
longitudinal fissure
fissure separating cerebellum from cerebrum
transverse fissure
an “island-like” sulci located deep within the brain, separating temporal lobe from frontal and parietal lobes
insula
sulci forming the boundary between the frontal and the parietal lobes on the lateral and medial surfaces
central sulcus
sulci separating parietal and occipital lobes
parieto-occipital sulcus
superficial sulcus separating temporal lobe from the frontal and parietal lobe
lateral sulcus
gyri on the lateral surface of each frontal lobe, anterior to the central sulcus and before precentral sulcus
precentral gyrus
gyri on the lateral surface of the parietal lobes between the central sulcus and postcentral sulcus
postcentral gyrus
Generates signals to direct the movement of the body. located anterior to the central sulcus
primary motor cortex
involved in planning and organizing movements and actions
motor association area
receives sensory information from the somatic senses, plus proprioceptive senses and some visceral senses
primary somatosensory cortex
area where sensory information is interpreted and made logical
somatosensory association area
receives visual signals
primary visual cortex
helps recognize and makes sense of what we see
visual association area
detects sound and discrimination of frequency
primary auditory cortex
responsible for processing acoustic (sound) signals that the brain interprets as sounds, speech or music
auditory association area
controls complex movement resulting in speech
motor-speech cortex/Broca’s area
intelligently regulates our thoughts, personality, actions and emotions through extensive connections with other brain regions
prefrontal cortex
