Crest

extension and projection

Answer 5

A narrow ridge (iliac crest of the pelvis)

Condyle

articulation

Answer 20

A rounded knob that articulates with another bone (occipital condyles of the skull)

Question 21

Foramen

passage and cavity

Answer 21

A hole through a bone, usually round (foramen magnum of the skull)
