Final answer:
The area between the apex and the back of the parietal ridge involves part of the parietal lobes, responsible for sensory functions and some cognitive skills like reading and arithmetic, as well as areas below the vision-controlling occipital lobes.
Step-by-step explanation:
The area of the head located between the apex and the back of the parietal ridge corresponds to the region of the cranial cavity that houses important structures related to our sensory functions. The apex of the head is typically representative of the highest point on the skull, and the back of the parietal ridge, which denotes the posterior border of the parietal bones, forms the division between the middle and posterior cranial fossae. This area would, therefore, be involved in some of the functions of the parietal lobes, which include sensation, such as temperature, touch, and taste, as well as reading and arithmetic. It also encompasses areas just below where the occipital lobes are found, which are primarily responsible for vision. Detailed anatomical structures within this region include the petrous ridge, which houses the middle and inner ear structures.
