Question

Number of bones in cranium, face, hyoid and middle ear are respectively

Answer 1

Hint: The skull contains a total of 29 bones out of which some are cranial bones and some are facial bones. The hyoid bone and ear ossicles, present in the middle ear, are also a part of the skull.

Complete answer:
To answer this question, let us know about the human skeletal system. The human skeletal system forms the structure and shape of the body. It is composed of bones and cartilages. It is composed of 206 bones and is divided into the Axial skeletal system and appendicular skeletal system.
- The axial skeletal system runs along the body’s central axis and consists of the bones of the skull (29 bones), rib cage (25 bones) and vertebral column (26 bones)
- The appendicular skeletal system consists of the pectoral girdle (2 bones), upper limbs (60 bones- 30 left and 30 right), lower limbs (60 bones- 30 left and 30 right) and the pelvic girdle (4 bones).

As stated above, the skull consists of 29 bones which are-
- Cranial bones- 8 (Occipital, Two Parietals, Frontal, Two Temporals, Sphenoidal, Ethmoid)
- Facial bones- 14 (Two Nasals, Two Maxillae, Two Lacrimals, Two Zygomatics, Two Palatines, Two Inferior - Nasal Conchae, Vomer and Mandible)
- Hyoid bone- 1
Ear ossicles present in the middle ear- 6 (Malleus, Incus and Stapes)

Hence, the number of bones in the cranium, face, hyoid, and middle ear are respectively 8, 14, 1 and 6.

Note: The main functions of skeletal system are-
- Provide structure and shape to the body
- Protection of vital organs
- Production of blood cells
- Storage of minerals
- Help in movement
