Question

Glenoid cavity is associated with
A. Scapula
B. Humerus
C. Femur
D. Both A and B

Answer 1

Hint: Glenoid Cavity: It is a superficial depression on a bone into which another bone is placed to form a joint.
It is located on the lateral angle of the scapula.
It is governed laterally and in forward direction and which further articulates with the head of the humerus.
It is broader at the base than the upper portion and its vertical diameter is the longest.

Complete answer:
The shoulder consists of a group of structures in the area of the joint.
The main joint in the shoulder is the shoulder joint.
It is a ball and socket joint that allows the arm to rotate in a circular angle.
The glenoid cavity or glenoid fossa is a part of the shoulder.
It is a superficial, pyramidal surface which is located on the lateral side of the scapula.
This cavity forms the gleno-humeral joint with the humerus.
This type of joint is categorized as a
1. Synovial Joint
2. Ball Joint
3. Socket Joint
The humerus is held in place within the glenoid cavity with the biceps tendon.
Scapula: It is a bone that connects the humerus and the clavicle with each other.
Humerus: It is the longest bone in the arm that runs from the shoulder to the elbow.
It connects the scapula and the two bones of the lower arm, the radius and ulna.
In the human thigh, only femur bone is present.
It is regarded as the longest and the strongest bone in the human body.

So, the correct option is option is option D. Both A and B.

Note:
A pectoral girdle or shoulder girdle attaches the bones of the upper limb to the axial skeleton.
Each pectoral girdle is produced by two halves.
Each half of the pectoral girdle consists of a scapula and clavicle.
The Glenoid cavity articulates with the humerus to form shoulder joints.
