Question

The Peak of the Scapula, the Lateral Part of the Spine. It Articulates to Clavicle in a Synovial Joint. Serves as an Insertion Point of the Trapezius.

a) Acromion
b) Glenoid fossa
c) Coracoid process
d) Spinous process

Answer 1

The part of the scapula described in the question is the acromion, which forms a synovial joint with the clavicle and serves as an insertion point for the trapezius.

Step-by-step explanation:

The peak of the scapula that articulates with the clavicle in a synovial joint and serves as an insertion point for the trapezius muscle is known as the acromion. The acromion is a flattened bony process that extends laterally from the spine of the scapula and forms the bony tip of the shoulder, noted for articulating with the lateral end of the clavicle to form the acromioclavicular joint. This should not be confused with the coracoid process, which is a hook-like process projecting anteriorly and the glenoid fossa, which is the part of the scapula that joins with the humerus to form the shoulder joint.
