Question

Total number of bones in the human skull is?
A. 22
B. 29
C. 35
D. 72

Answer 1

In human skeleton, the bony structure forming the head is known as the skull/human skull. It consists of the cranial bones and the facial skeletal bones. It provides protection to the brain against various injuries.

Complete answer:
The cranium or the human skull in general is considered to be formed of twenty two bones. Some of these bones occur in pairs while others are not found paired up. Of the twenty two bones, eight bones are the cranial bones while the rest fourteen are referred to as the facial skeletal bones. The Neurocranium is composed of two parietal bones, two temporal bones, one occipital bone, one ethmoid bone, one sphenoid bone and one frontal bone. However, facial bones consist of two nasal bones, two maxillary bones, two lacrimal bones, two palatine bones, two inferior nasal conchae, two zygomatic bones, one vomer and one mandible.
Some of the neurocranial bones like frontal bone, parietal bone, occipital bone and some facial skeleton bones like lacrimal bone, vomer bone, nasal bone are the flat bones. They help in supporting the facial structures and in the formation of cavities for the brain.

Hence, the correct answer is option (A).

Note: Sutures which are also known as the synarthrodial joints are the immovable joints that join together all the skull bones except for the mandible. Bony ossification helps in formation of these joints with Sharpey’s fibers which provide them with some flexibility.
