What connects bone to bone?
None of these.
Ligaments.
Tendons.
Syndesmosis.
The Correct Answer is B
A ligament is a type of fibrous connective tissue that connects bone to bone. It usually serves to hold structures together and keep them stable.
For example, the anterior cruciate ligament (ACL) connects the femur and the tibia in the knee joint.
Choice A is incorrect because none of these is not a valid answer.
Choice C is incorrect because tendons are fibrous connective tissues that connect muscle to bone.
For example, the Achilles tendon connects the gastrocnemius muscle to the calcaneus bone in the ankle.
Choice D is incorrect because syndesmosis is a type of fibrous joint that connects two bones by a ligament or an interosseous membrane.
For example, the distal tibiofibular joint is a syndesmosis joint.

Correct Answer is ["The olecranon fossa"]
Explanation
The olecranon fossa is a depression located on the posterior aspect of the distal end of the humerus bone, just above the trochlea.
It is part of the elbow joint and serves as a resting place for the olecranon process of the ulna bone during elbow extension.
The fossa is bordered by the medial and lateral epicondyles of the humerus and is separated from the trochlea by a thin medial ridge.
The olecranon fossa is an important landmark for orthopedic surgeons as it provides access to the distal humerus for surgical procedures, such as total elbow replacement.
Injury to the olecranon fossa can result in fractures or dislocations of the elbow joint.
