Final answer:
The inferior parietal lobe consists of two parts: the supramarginal gyrus and the angular gyrus. These parts handle various functions including sensory processing, language perception, and spatial cognition.
Step-by-step explanation:
The two parts that make up the inferior parietal lobe are the supramarginal gyrus and the angular gyrus. These regions are involved in various functions related to sensory processing and integration. For instance, the supramarginal gyrus plays a role in language perception and processing, while the angular gyrus is involved in complex language and number processing, as well as spatial cognition. This localization of functions within the parietal lobes ties into the larger role of the parietal lobe in terms of somatosensation and proprioception, with additional involvement in reading and arithmetic tasks. The parieto-occipital sulcus is a notable anatomical feature separating the parietal and occipital lobes, indicating the interrelated functions of these cortical regions.
