What part of the cerebral cortex receives sensory input for touch and body position?

• A. Frontal lobes
• B. Parietal lobes
• C. Occipital lobes
• D. Temporal lobes

Answer: (B)

The part of the cerebral cortex that receives sensory input for touch and body position is the parietal lobes. This region is responsible for processing sensory information related to tactile sensations, proprioception (the sense of body position and movement), and spatial awareness. The primary somatosensory cortex, located within the parietal lobes, is specifically involved in interpreting signals from the skin, muscles, and joints, allowing individuals to perceive sensations like pressure, pain, and temperature. In contrast, the frontal lobes are primarily involved in higher cognitive functions such as decision-making, planning, and motor control; the occipital lobes are dedicated to visual processing; and the temporal lobes play a key role in auditory processing and memory. Each of these other lobes has distinct functions that do not directly address the processing of tactile and proprioceptive data, making the parietal lobes the correct choice for this question.
