SSC Selection Post 2019 PYQ — Question 35

The correct answer is option 2 i.e. 22.

The human skull is composed of 22 bones, which are categorized into two main groups: the cranial bones and the facial bones. The cranial bones, totaling eight, form the protective case around the brain and include the frontal bone, two parietal bones, two temporal bones, the occipital bone, the sphenoid bone, and the ethmoid bone. The facial bones, numbering fourteen, constitute the structure of the face and support the teeth and eyes. These include the nasal bones, maxillae, zygomatic bones, palatine bones, lacrimal bones, inferior nasal conchae, vomer, and the mandible. These bones are interconnected by immovable joints known as sutures, which fuse over time, particularly after birth. The skull's primary functions are to protect the brain, support the structures of the face, and house the organs of the senses.
