Q

A projection or outgrowth of a tissue from a larger body

A

Process

Ex. Mastoid process

3
Q

Rounded elevation on the surface of a bone

A

Protuberance

Ex. posterior surface of the occipital bone (Occipital protuberance)

4
Q

Projection of bone located at articulation points

6
Q

Shallow indentation that transmits blood vessels and nerves

A

Groove

Ex. the internal surfaces of skull bones will contain grooves for various arteries, veins and venous sinuses

7
Q

Large opening in the skull

A

Aperture

Ex. piriform aperture (part of nasal passageway)

8
Q

Circular or oval-shaped opening in the skull bones

A

Foramen

Ex. Foramen magnum (largest opening in the skull to allow the spinal cord to exit the skull)

9
Q

Narrow, cleft-like opening between adjacent parts of a bone or bones forming a passageway for blood vessels and nerves

A

Fissure
Ex. Superior orbital fissure (narrow opening between the greater and lesser wings of the sphenoid bone)

Inferior orbital fissure (narrow opening between the greater wings of the sphenoid and the orbital surface of the maxillary bone)

10

The mastoid process is a feature of which bone of the cranium?

A

Temporal bone
