What is the total number of bones present strictly in the hand region (comprising the wrist, palm, and digits) of a single human forelimb?

Options

  1. A27
  2. B30
  3. C29
  4. D26

Correct answer

A. 27

Step-by-step solution

The hand region of a human forelimb consists of the wrist, palm, and digits. According to NCERT, the number of bones in these regions of one forelimb are: Wrist bones (Carpals) = 8 Palm bones (Metacarpals) = 5 Digit bones (Phalanges) = 14 Total number of bones = 8 + 5 + 14 = 27. The total number of bones in the entire forelimb is 30, which includes the humerus (1), radius (1), and ulna (1), but these are not part of the hand region. Answer: 27
