Final answer:
Fossae and foramina are depressions and openings in bones that provide pathways for the passage of vessels and nerves, such as those in the skull for major nerves and arteries.
Step-by-step explanation:
The depressions and grooves formed for the passage of vessels and nerves in bones are known as fossae and foramina. Foramina are holes through the bone that provide pathways for nerves and blood vessels. Fossae refer to the depressions on the surface of bones, which often serve as sites for muscle attachment or articulation with other bones. Examples of these include the cranial fossae, subdivided into anterior, middle, and posterior, which hold corresponding parts of the brain. Other significant openings include the foramen ovale and carotid canal, which allow for the passage of major nerves and arteries respectively.
