Questions and Answers

Describe a Condyle. Provide an example.

A bump/ projection at the end of a bone that forms a joint with another bone. There is a lateral and medial condyle on the end of the femur.

What is a Head in bone structure? Give an example.

The rounded projection at the end of a bone which forms a joint. There is a head on the rib that connects to the spine and there is one on the femur to connect to the hip bone.

Study Notes

Bone Features

  • Articular Surfaces:

    • Condyle: A rounded projection at the end of a bone that forms a joint. Examples include the lateral and medial condyles of the femur.
    • Head: A rounded projection at the end of a bone that forms a joint. Examples include the head of a rib connecting to the spine and the head of the femur connecting to the hip bone.
    • Trochlea: A groove on the end of a bone that allows movement in joints. An example is the trochlea on the end of the humerus interacting with the radius/ulna for the elbow joint.
  • Depressions:

    • Fossa (Pl., Fossae): A depression in a bone. Examples include the supraspinous and infraspinous fossae on the scapula.
  • Projections for Tendon and Ligament Attachment:

    • Crest: A raised part of a bone edge. An example is the iliac crest on the ilium of the coxal bone.
    • Epicondyle: A bump on a long bone where tendons and ligaments attach to muscles. Examples include the medial and lateral epicondyles of the humerus.
    • Line: Lines or impressions on bone from the texture of the surrounding tissues. Or the epiphyseal line.

Other Bone Features

  • Process:

    • Trochanter: A bony projection for the attachment of muscles, tendons, or ligaments. An example is the greater and lesser trochanters of the femur.
    • Tubercle: A small bump on a bone. Examples include the greater and lesser tubercles on the head of the humerus.
    • Tuberosity: A rounded area on a bone where muscles and ligaments attach. An example is the ulnar tuberosity below the olecranon process on the ulna.
  • Openings:

    • Canal: A tubular passageway. Example: the carotid canal in the temporal bone.
    • Fissure: A narrow split or groove. Examples include the superior and inferior orbital fissures.
    • Foramen (Pl., Foramina): A hole in the bone where structures pass through. Example: the foramen magnum connecting the brain to the spinal cord.
    • Sinus: Hollow spaces inside bones. Example: sphenoidal sinus, located behind the eyes.
