A condyle is a rounded knob that articulates with another bone.
A crest is a narrow ridge.
A tubercle is a small, rounded process.
A fossa is a shallow, broad, or enlongated basin.
A sulcus is a groove for a tendon, nerve, or blood vessel.
A foramen is a hole through the bone that is usually round.
Work Step by Step
Condyles are the rounded parts that articulate with other bones and are usually found on the ends on bones. Examples include the medial and lateral condyles of the femur which connect to the tibia and help form the knee join.
Crests are narrow ridges or raised surfaces. A good example of a crest is the iliac crest of the pelvis.
Tubercles are small, rounded processes. Larger tubercles are also known as tuberosities. Examples include the greater and lesser tubercles of the humerus which connect the humerus to the scapula.
Fossa are a shallow, broad, or enlongated basins. They can also be described as a depression or a hollow. The mandibular fossa, which is the depression in the temporal bone that connects to the mandible, is a good example.
A sulcus is a groove for a tendon, nerve, or blood vessel. An example is the intertubercular sulcus of the humerus for the tendon of the long head of the biceps muscle.
A foramen is a hole through the bone that is usually round. An excellent example is the foramen magnum of the skull allowing for the passage of the spinal cord to the brain.
