Broca area

Bro·ca cen·ter

(brō-kah'), the posterior part of the inferior frontal gyrus of the left or dominant hemisphere, corresponding approximately to Brodmann area 44; Broca identified this region as an essential component of the motor mechanisms governing articulated speech. Synonym(s): Broca area, Broca field, motor speech center

Broca area

The area of the left hemisphere of the brain at the posterior end of the inferior frontal gyrus. It contains the motor speech area and controls movements of tongue, lips, and vocal cords. Loss of speech may follow any stroke affecting this area. Synonym: Broca center; Broca convolution; motor speech area; speech center See: motor aphasiaSee also: Broca, Pierre-Paul
