Question

Part of pectoral girdle is
A. Ileum
B. Glenoid cavity
C. Acetabulum
D. Sternum

Answer 1

It is a pyriform, shallow, articular surface that stands on the side corner of the scapula. The articulate forms the shoulder joint with the humerus.

Complete answer:
The shoulder girdle or pectoral girdle is an arrangement of bones on either side of the appendicular skeleton. It consists of a clavicle and a scapula in humans. The coracoid, clavicle, and scapula are included in those animals which have 3 bones in the shoulder. There are only such mammalian animals (such as the dog and the horse). The pectoral girdles are in the upper limbs, while the pelvic girdle is in the lower limbs; the girdles are the portion of the skeleton connected to the axial skeleton.
The ileum is the third and last part of the small intestine. It traces the jejunum and ends at the junction between the Ileum and the cecum through the Ileocecal valve. The ileum terminal interacts with the cecum.

The glenoid cavity or glenoid scapula fossa is a shoulder portion. The articular surface is pyriform and shallow and is located at the side angle of the scapula. The humerus head is directed laterally and forward. It is wider than above and it has the longest vertical diameter.
The pelvic surface is a concave acetabulum. The femur's head meets the acetabulum pelvis and shapes the hip joint.

The sternum is a long, flat bone in the middle of the chest. It binds to the ribs by cartilage and forms the front of the rib cage to protect the cardiovascular system against injury.
Thus, the correct answer is option B. i.e., Glenoid cavity.

Note: The shoulder girdle is the mechanism of anatomy which enables all movements of the upper arm and shoulder of a man. The shoulder girdle consists of five muscles which attach to the clavicle and scapula and permit the motion of the sternoclavicular joints and acromioclavicular joints. The five muscles which provide the shoulder girdle function are the trapezius, levator scapulae muscle, the rhomboid muscles, the anterior serratus muscle and the pectoralis minor muscle.
