Question

Skull of man is made up of:
A. $10$ bones
B. $22$ bones
C. $30$ bones
D. $24$ bones

Answer 1

In vertebrates, the skull is a bone structure that forms the head. It provides a protective cavity for the brain and supports facial structures. The cranium and the mandible are the two pieces of the skull. The neurocranium and the viscerocranium (facial skeleton), which encompasses the mandible as its largest bone, are the two components of the human skull.

Complete explanation:
Option A: The cranial part of the skull alone contains $8$ bones. Above that, the facial part has more than $2$ bones ($14$ bones actually).
Hence, option A is incorrect.
Option B: The skull is made up of $22$ bones divided into two groups: cranial and facial. The number of cranial bones is eight. They shape the cranium, the brain's hard protective outer covering. The front portion of the skull is made up of $14$ skeletal elements that make up the facial area.
As a result, the human skull is made up of $22$ bones, and therefore the correct answer is '$22$ bones.'
Hence, option B is the correct answer.
Option C: The facial portion of the skull encompasses $14$ bones, and the cranial part of the skull has $8$ bones. So, the total of these two parts is not $30$.
Hence, option C is incorrect.
Option D: The total bones in the skull encompass the $8$ bones of the cranium and the $14$bones of the facial part of the skull. The total of this goes to $22$. There are no two extra bones in the skull. $24$ is not the correct number.

Hence, option D is the correct answer.

Note:
The skull's functions include protection of the brain, adjusting the distance between the eyes to allow stereoscopic vision, and adjusting the location of the ears to allow sound localization of sound direction and distance. The skull also serves a defensive role in certain species, such as horned ungulates (mammals with hooves), by providing amount (on the frontal bone) for the horns.
