Function and Location of Part of Brain Flashcards
primary motor cortex
-located on pre-central gyrus of frontal lobe
-controls voluntary muscle movements on opposite side of body, involved in skilled, complex, or delicate movements (thumbs, fingers, lips)
premotor cortex
-located anterior to precentral gyrus of frontal lobe
-controls learned skilled movements and the “programs” for carrying out sequential muscle movements
Broca’s speech area
-located in only the left frontal lobe
-involved in planning and production of speech (relaying impulses to motor cortex and muscles of tongue, cheek, larynx and lips)
What is the function of the association right area of Broca’s area in the frontal lobe?
contains the affective language area (gives ability to put emotion into speech)
Frontal Eye Field
-located anterior to premotor cortex
-controls voluntary movements of the eyes (looking L vs R)
Primary somatosensory cortex
-located on post-central gyrus of parietal lobe
-receives general sensory receptors in skin (touch, pressure, hot/cold, itch)
-allows for spatial discrimination (identify body location that is being stimulated)
Somatosensory association area
-located posterior to primary somatosensory area
-integrates and interprets sensations (position of limbs, location of touch/pain, determination of weight, texture, shape, stores past memories of sensation)
Primary Visual cortex
-located in occipital lobe
-allows for recognition of shape, color, movement of visual stimuli
Visual association area
-located in occipital lobe
-allows for recognition of visual stimuli, relates past and present visual experiences (deja vu)
Primary Auditory complex
-superior margin of temporal lobe
-interprets sound (pitch, loudness, rhythm, location)
Auditory Association area
-posterior to temporal lobe
-ability to recognize speech, music, noise, memory of past sounds stored here (how you’d recognize someone’s voice)
Olfactory complex
-located on the medial aspect of temporal lobe
-provides ability to recognize different smells
Gustatory cortex
-located on the insula
-perception of taste (sweet vs salt)
Visceral sensory area
-located on the insula
-provides perception of visceral sensations (upset stomach, full bladder, lungs going to burst when holding breath)
Multimodal association areas
-aids in learning (giving meaning to information received, store it to memory, tie to previous experience, decide action)
-impulses relayed to premotor cortex then primary motor cortex
