In human body which one is anatomically correct:

Question

Accepted Answer

The correct option is 3: Floating ribs -2 pairs.
In the human rib cage, there are 12 pairs of ribs. The first seven pairs are known as true ribs because they connect directly to the sternum (breastbone) via their own costal cartilage. The next three pairs (8, 9, and 10) are called false ribs because their cartilage attaches indirectly to the sternum by joining the cartilage of the rib above them. The last two pairs, the 11th and 12th ribs, are unique; they are called floating ribs because they do not attach to the sternum or to the cartilage of other ribs at all. Instead, they are only attached to the vertebrae posteriorly. This arrangement allows for greater flexibility in the lower thoracic cage and is anatomically correct as two pairs.

The incorrect option is 1: Salivary glands -1 pair.
Humans actually have three pairs of major salivary glands: the parotid glands, the submandibular glands, and the sublingual glands. Each of these three types is present as a pair, making a total of three pairs, not just one.

The incorrect option is 2: Cranial nerves -10 pairs.
The human body has 12 pairs of cranial nerves, not 10. These nerves originate directly from the brain and brainstem, and they are crucial for various sensory and motor functions of the head and neck.

The incorrect option is 4: Collar bones -3 pairs.
Humans have only one pair of collar bones, also known as clavicles. These two bones are located horizontally at the base of the neck, forming the anterior part of the shoulder girdle and connecting the scapula to the sternum.
