MCQ Detailed View

Each human hand is made up of 27 bones, which provide both strength and flexibility. These bones allow us to perform a variety of tasks, from gripping and holding to delicate movements like writing or drawing.

The bones in the hand are divided into three main groups:

1. 
   

   Carpals (8 bones) – The small wrist bones that connect the hand to the forearm.

   
   


2. 
   

   Metacarpals (5 bones) – These form the middle part of the hand and connect the wrist to the fingers.

   
   


3. 
   

   Phalanges (14 bones) – These are the finger bones. Each finger has three phalanges (proximal, middle, distal), except the thumb, which has two phalanges.

   
   

When you add them together:

• 
  

  8 carpals + 5 metacarpals + 14 phalanges = 27 bones per hand.

  
  

This bone arrangement allows the hand to be highly flexible and functional, supporting a wide range of motions and precise movements. The bones also work with muscles, tendons, and ligaments to ensure smooth and coordinated hand actions.

Other options are incorrect:

• 
  

  26, 28, and 30 do not correctly represent the total number of bones in a single hand.

  
  

Understanding the number of bones in the hand is a key part of biology, particularly in human anatomy and physiology. It helps students learn how the skeletal system supports movement, dexterity, and coordination in daily life.

In short, each human hand has 27 bones, including carpals, metacarpals, and phalanges, giving it the structure and flexibility needed for complex activities.
