Question

the depression of the skull at m is called the ____ ____ (two words).

Explanation:

To determine the depression at M in the cranial floor (internal skull view), we recall anatomical terms for skull depressions. The area at M (on the occipital bone, near the foramen magnum - H) is the "hypoglossal fossa" or more commonly, the "cerebellar fossa" is incorrect. Wait, no—correction: The depression at M (part of the occipital bone, forming the cranial floor's posterior fossa region) is the cerebellar fossa? No, more accurately, the "hypoglossal fossa" is for the hypoglossal canal, but M is in the posterior cranial fossa. Wait, the posterior cranial fossa has depressions for the cerebellum, so the correct two - word term is "cerebellar fossa"? No, actually, the depression at M (on the occipital bone, part of the posterior cranial floor) is the cerebellar fossa? Wait, no, let's think again. The posterior cranial fossa contains the cerebellum, and the depressions there are called the "cerebellar fossae" (plural), but for a single depression (M is likely one of the cerebellar fossae). Wait, another approach: The cranial floor has three fossae: anterior, middle, posterior. The posterior cranial fossa (where M is, near the foramen magnum H) has depressions for the cerebellum, so the depression at M is the "cerebellar fossa". But wait, maybe "hypoglossal fossa" is wrong. Wait, the hypoglossal canal is near, but M is more posterior. Wait, the correct term for the depression in the occipital bone (part of posterior cranial fossa) for the cerebellum is the "cerebellar fossa". Alternatively, "jugular fossa" is for the jugular foramen, but G is near jugular. Wait, M is on the occipital bone, posterior cranial fossa. The posterior cranial fossa's depressions are the cerebellar fossae. So the two - word term is "cerebellar fossa". Wait, no, maybe "hypoglossal fossa" is incorrect. Wait, let's check anatomical terminology: The posterior cranial fossa is divided into the cerebellar fossae (for the cerebellum) and the clivus. So the depression at M (part of the occipital bone, posterior cranial fossa) is the "cerebellar fossa".

Answer:

cerebellar fossa
