Answer 1

Hint:-The cranium is a group of bones which encase the brain and provide shape to the head and face. The upper jaw is a part of the cranium. The human cranium, the element that consists of the brain, is globular and comparatively huge in contrast with the face.

Complete answer:
The bones on your cranium may be divided into the cranial bones, which shape your cranium, and facial bones, which make up your face. The bones of the cranium consist of the following: the frontal, parietal, occipital, temporal, sphenoid, ethmoid, zygomatic, maxilla, nasal, vomer, palatine, inferior concha, and mandible.
There are two types of bones in the cranium-
- Flat bones
- Irregular bones
There are 8 cranial bones and each has their unique shape, below are the names of each bone-
- Frontal bone
- Temporal bones (pair of bones)
- Parietal bones (pair of bones)
- Occipital bone
- Sphenoid bone
- Ethmoid bone
- There are 14 facial bones-
- Nasal bones (paired)
- Maxilla (paired)
- Vomer
- Mandible
- Palatine bones (paired)
- Lacrimal bones (paired)
- Zygomatic bones (paired)
- Inferior nasal concha (paired)
Hence, correct answer is (d) 22

Note:- The skull is composed of two parts; neurocranium and viscerocranium. Cranium are the bones that form the skull. All together they form a group of bones which makes our posterior shapes for our face. The mandible, or jaw bone, is the only movable bone of the skull. Our occipital bone contains the foramen magnum, the hole through which the spinal cord enters the skull to attach to the brain.
