  1. BONE LANDMARKS Bone landmarks are specific locations at which major muscles, ligaments, or other connective tissue attach. The following will familiarize you with basic landmarks and their specific locations on bones.

  2. Surface Markings on Bones Depressions & Openings • Foramen • Rounded opening through which blood vessels, nerves and ligaments pass • i.e. Foramen magnum of the skull • Fossa • A broad, shallow depressed area. • Depression in or on a bone • i.e. Olecranon fossa of the humerus

  3. Projections • Process • A relatively large projection or prominent bump. • Any prominent roughened projection • i.e. Mastoid process of temporal bone • Condyle • A large, rounded articular process. • A large convex prominence • i.e. Medial/lateral condyle of femur • Epicondyle • A projection near to a condyle but not part of the joint. • A projection located just above a condyle • i.e. Medial/lateral epicondyle of femur • Head • Rounded projection supported on the neck of the bone • i.e. Head of the humerus

  4. Tuberosity • A projection or bump with a roughened surface • Large rounded, usually rough, process • i.e. Radial tuberosity of the radius • Tubercle • A projection or bump with a roughened surface, generally smaller than a tuberosity. • Small rounded bones • i.e. Greater tubercle of the humerus • Trochanter • One of two specific tuberosities located on the femur. • Very large blunt projection • i.e. Greater trochanter of the femur • Crest / Spine • Prominent border or ridge on a bone • i.e. Crest of the ilium
