Bone depressions
The medical term is "articular surfaces." These are the areas on bones where they come together at joints to form depressions and hollows that allow for movement and stability.
Depressions are indentations or hollowed-out areas on bones, while processes are bony projections or outgrowths that serve as attachment sites for muscles, ligaments, or tendons. Depressions can accommodate other bone structures or provide passageways for blood vessels and nerves, while processes play a role in joint formation and movement.
The axial skeleton.
The body consists of long bones, flat bones, irregular bones, short bones and sesmoid bones. The short bones include bones in the wrist and foot.
The group of bones of the wrist are the carpals, and of the ankles are the tarsals. Each of the carpals and tarsals has an individual name as well. The bones of the palm are the metacarpals, and the bones of the sole are the metatarsals. The finger bones and toe bones are both called phalanges.
Anticyclones are high pressure arear and depressions are low pressure areas.
The depressions on the moon are impact craters formed by collisions with asteroids and comets.
There are 8 cranial bones in the human skull. They include the frontal bone, parietal bones, temporal bones, occipital bone, sphenoid bone, and ethmoid bone.
The superior bones of the skull include the frontal bone, parietal bones, and occipital bone. These bones form the top and back part of the skull, providing protection for the brain.
Bumps and depressions in the skull are more closely related to the thickness and contour of the skull bones themselves rather than the development of underlying brain areas. They can be influenced by genetics and environmental factors, but do not necessarily correlate with the development of specific brain regions.
Bony prominence is developed by muscle pull. That is why you have well marked bony markings in case of a male bones. But then it requires the comment from the expert as to why there are depressions on some muscle origins or insertions.
