Which is the plural form of 'foramen', meaning a hole that nerves, arteries and veins pass through?

Correct Answer: B

Rationale: The plural of 'foramen' (Latin for hole) is 'foramina,' following Latin grammatical rules, as seen in terms like 'foramen magnum.' 'Foramens' is an incorrect Anglicized plural.

Rationale: Red marrow, located in spongy bone cavities (e.g., vertebrae, pelvis), produces blood cells (hematopoiesis), including red blood cells, white blood cells, and platelets.
