Bone Terminology Bone Terminology • Process – – – – – A prominent projection Example: coronoid process Example: zygomatic process Example: styloid process Example: mastoid process • Condyle – A rounded process which articulates with another bone – Example: occipital condyle – Example: femur • Crest – Narrow, ridge-like projection – Example: iliac crest • Epicondyle – Projection located above a condyle – Example: humerous – Example: femur More Bone Terminology Skull (lateral) coronoid process RETURN Skull (lateral) zygomatic process of temporal bone RETURN Skull (lateral) styloid process

Examples: infant skull • Foramen – An opening through a bone – Example: foramen magnum – Example: vertebral and transverse foramina • Fossa – Deep depression – Example: humerous More Bone Terminology
