Between which two bones is the Acromioclavicular joint?
Ulna and Scapula.
Scapula and Clavicle.
None.
Humerus and Scapula.
The Correct Answer is B
The acromioclavicular joint is the articulation between the acromion of the scapula and the acromial end of the clavicle.
It is a plane synovial joint that allows movements of the shoulder girdle. Choice A is incorrect because the ulna and scapula do not form a joint.
The ulna is a bone of the forearm that articulates with the humerus and radius. Choice C is incorrect because none is not a valid option.
There is a specific joint between two bones that is called the acromioclavicular joint.
Choice D is incorrect because the humerus and scapula form a different joint, called the glenohumeral joint.
This is a ball-and-socket synovial joint that allows movements of the shoulder.

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.
Correct Answer is ["linea aspera"]
Explanation
The linea aspera is a ridge of bone on the posterior surface of the femur.
It is a prominent feature that serves as a site of attachment for several important muscles, including the adductor magnus, vastus medialis, and the long head of the biceps femoris.
The linea aspera extends from the greater trochanter of the femur to the lateral condyle of the femur, dividing the posterior surface of the bone into two distinct regions.
The medial lip of the linea aspera serves as an attachment site for the adductor magnus, while the lateral lip provides attachment for the vastus medialis and the long head of the biceps femoris.
Injuries to the linea aspera can occur as a result of direct trauma or repetitive stress and can cause pain and discomfort in the thigh.
