Q: In which part of the human body carpal bones are found ?

A: Wrist

B: Femur

C: Neck

D: None of these



Correct Option: A  [ Wrist ]

Remark:

Explanation: Carpal bones are the eight small bones that make up the wrist (also known as the carpus) in the human skeletal system. These bones are arranged in two rows — a proximal row (closer to the forearm) and a distal row (closer to the hand). They connect the bones of the forearm (radius and ulna) to the bones of the hand (metacarpals) and allow for the flexibility and movement of the wrist. The carpals are essential for various hand motions like bending, rotation, and gripping.


Q: Number of spinal nerves in human are:

A: 11 pairs

B: 27 pairs

C: 32 pairs

D: 31 pairs



Correct Option: D  [ 31 pairs ]

Remark:

Explanation: In humans, the spinal cord gives rise to 31 pairs of spinal nerves. Each spinal nerve is a mixed nerve containing both sensory and motor fibers. They are divided into groups based on the region of the vertebral column from which they originate:

  • 8 pairs — Cervical nerves
  • 12 pairs — Thoracic nerves
  • 5 pairs — Lumbar nerves
  • 5 pairs — Sacral nerves
  • 1 pair — Coccygeal nerve

These spinal nerves connect the central nervous system (CNS) to different parts of the body, transmitting sensory information to the brain and motor commands to muscles.

Q: The ingredient that assists clotting of blood is:

A: Vitamin A

B: Folic acid

C: Vitamin D

D: Vitamin K



Correct Option: D  [ Vitamin K ]

Remark:

Explanation: Vitamin K plays a crucial role in the blood clotting process. It helps the liver synthesize prothrombin and other clotting factors required to stop bleeding when injuries occur. Deficiency of Vitamin K can lead to excessive bleeding and delayed clot formation. Green leafy vegetables, broccoli, spinach, and intestinal bacteria are major natural sources of this vitamin.

B: Scattering of Sunlight

C: Refraction of Sunlight

Q: Adult Filaria worms live in human:

A: Blood

B: Lymphatics

C: Liver

D: Intestine



Correct Option: B  [ Lymphatics ]

Remark:

Explanation: The adult filarial worm, Wuchereria bancrofti (and Brugia malayi), lives in the lymphatic vessels and lymph nodes of humans. These worms block the lymphatic system, causing a condition known as lymphatic filariasis or elephantiasis, characterized by severe swelling of legs, arms, or genitals. The disease is transmitted by the bite of infected Culex mosquitoes, which carry t
