MCQ Detailed View

The human skull is the bony structure that forms the head and protects the brain, eyes, and inner ears. In adults, the skull is made up of 22 bones in total. These bones are grouped into two main types:

1. 
   

   Cranial bones (8) – These bones form a protective case around the brain. Examples include the frontal, parietal, occipital, temporal, sphenoid, and ethmoid bones.

   
   


2. 
   

   Facial bones (14) – These bones form the structure of the face, including the maxilla, mandible, zygomatic, nasal, lacrimal, palatine, vomer, and inferior nasal conchae.

   
   

The skull provides a strong protective covering for the brain and sensory organs. It also serves as a support structure for the face, and attachment points for muscles used in chewing, speaking, and facial expressions.

Other options are incorrect:

• 
  

  25 and 26 are not correct counts for the adult skull without including the small ear bones separately.

  
  

Understanding the 22 bones of the skull is important in biology, especially in human anatomy and physiology. It helps students learn how the head is structured, how the bones protect vital organs, and how facial features are formed.

In short, the human skull has 22 bones, combining cranial and facial bones, providing protection, support, and structure for the head and its organs.
