Question

Two halves of pectoral girdle fuse in:
(a) Lateral sides
(b) Mid-dorsal sides
(c) Mid-Ventral Line
(d) Both dorsal and ventral line.

Answer 1

Hint: The shoulder girdle is the anatomical mechanism that allows for all upper arm and shoulder movement in humans. This shoulder girdle consists of five muscles that attach to the clavicle and scapula and allow for the motion of the steno-clavicular joint and acromioclavicular joint. These five joints that can be divided into two groups. Three of these joints are true anatomical joints while two are physiological joints. Within each group, the joints are mechanically linked so that both groups simultaneously contribute to the different movements of the shoulder to variable degree.

Complete answer
A pectoral girdle or shoulder girdle attaches the bones of the upper limb to the axial skeleton.
Each pectoral girdle is formed of two halves. Each half of the pectoral girdle consists of a scapula and circle. The scapula articulates with the clavicle and humans. The clavicles or collop’s bones are slender, doubly curved long bones, which articulate with the sternum.
Two halves of pectoral girdle (left and right) fuse in a mid-ventral line, each adjacent to a developing human.
pectoral girdles are responsible for providing structural support to your shoulder region on the left and right side of your body. They also allow for a large range of motion, connecting muscles necessary for shoulder and arm movement.

Hence option ‘C’ is the correct answer.

Note: The pectoral girdle is weaker than the pelvic girdle because the pelvic girdle is the primary weight. bearing and locomotion structure for the body.
Pectoral girdle is massive and one has a more sheller socket and more flexibility.
The pectoral girdle serves as a location of attachment for many muscles of the back, chest and neck that her upper limbs move.
