Out of the following pairs of the human skeletal parts, identify the w...
The wrongly matched pair is option 'B' - Clavicle and glenoid cavity are not related to each other.
Explanation:
The human skeletal system is divided into two main parts - the axial skeleton and the appendicular skeleton. The axial skeleton consists of the skull, vertebral column, ribs, and sternum, while the appendicular skeleton consists of the limbs and the girdles that attach the limbs to the axial skeleton.
Let's analyze each option to understand the correct and incorrect matches:
a) Sternum and ribs - Axial skeleton
The sternum is a flat bone located in the center of the chest that connects to the ribs via cartilage. Ribs are long, curved bones that form the rib cage and protect the vital organs in the thoracic cavity. Thus, this pair is correctly matched.
b) Clavicle and glenoid cavity - Pelvic girdle
The clavicle (collarbone) is a long bone that connects the shoulder blade (scapula) to the sternum. The glenoid cavity is a shallow depression on the scapula that forms a joint with the humerus (upper arm bone). Thus, this pair is wrongly matched.
c) Humerus and ulna - Appendicular skeleton
The humerus is the long bone in the upper arm that extends from the shoulder to the elbow joint. The ulna is one of the two bones in the forearm that extends from the elbow to the wrist. Thus, this pair is correctly matched.
d) Malleus and stapes - Ear ossicles
The malleus, incus, and stapes are the three tiny bones in the middle ear that transmit sound vibrations from the eardrum to the inner ear. The malleus is attached to the eardrum, the incus connects the malleus to the stapes, and the stapes is connected to the oval window of the inner ear. Thus, this pair is correctly matched.
Therefore, the correct answer is option 'B' - Clavicle and glenoid cavity.
