Must Know Broadmann's Areas Flashcards
Broadmann’s Area 4
primary cortex area
somatotopic organization
Size of areas is proportional to the degree of skill involved with movement
Broadmann’s Area 3,1,2
Primary Somatosensory Area
Somatotopically organized
Areas of cortex proportional to sensory discrimination of the area not to the amount of surface area
Broadmann’s Area 43
Primary Gustatory Cortex
Anterior part of parietal operculum
Posterior part of Area 43 is the secondary somatosensory area however the somatotopy is poorly defined
Broadmann’s Area 41 and 42
primary auditory cortex
Tonotopic organization
High frequency sounds posteromedial, and low frequency sounds anterolateral
Broadmann’s Area 44 and 45
Broca’s Area
Part of the inferior frontal gyrus
Functions in speech
Broadman’s Area 22
auditory association cortex
Wernicke’s area (posterior part of 22)
Language understanding and formulation
