Study Notes
Frontal Lobe
- Mainly concerned with control of movements
- Lies anterior to the central or rolandic sulcus
- Contains motor areas, including:
- Motor area (4): initiates voluntary motor activity of the opposite half of the body, located in the floor of the central sulcus
- Premotor area (6): shares the function of area 4, located in the anterior part of the precentral gyrus
- Other areas include:
- Motor speech center (Broca's area 44): responsible for speech, located in the middle part of the inferior frontal gyrus of the dominant hemisphere
- Writing center (Exner's area 45): located in the posterior part of the middle frontal gyrus
- Area 8 of voluntary conjugate eye movement: causes conjugate eye movements to the opposite side of stimulation, located in the posterior part of the middle frontal gyrus
- Prefrontal area: concerned with higher mental functions of memory, orientation, thinking, intelligence, and personality, occupies the anterior pole
Parietal Lobe
- Lies behind the central sulcus
- Mainly concerned with sensation
- Areas of particular importance include:
- Cortical sensory areas 1, 2, 3: concerned with perception of cortical sensations from the opposite half of the body, located in the posterior central gyrus
- Visual psychic area 39 of speech: concerned with recognition of written speech, located in the dominant hemisphere
This quiz covers the functions and structures of the frontal lobe, including the motor area, premotor area, and motor speech center. Test your knowledge of the frontal lobe's role in controlling movements and voluntary motor activity.
