Question

Humerus bone is present in the
A. Upper arm
B. Lower arm
C. Lower jaw
D. Thigh

Answer 1

Hint:The skeletal system is a system of hardened external and internal structures, living or dead, which form the supporting, protective, and joint framework of the body. The skeleton is made up of hard or soft, internal or external components of the animal body, such as bones and cartilage. The movement or locomotion of various parts of the body is the responsibility of the skeletal system.

Complete answer:
The skeleton of the arms, the pectoral and pelvic girdles that shield and hold the skeleton of the limbs from the spine are included in the skeleton of the appendix. The pectoral girdle is called the girdle that supports the forelimb, and the girdle that supports the hind legs is called the pelvic girdle. The appendicular skeleton thus consists of the limb bones, the pelvic girdle, and the pectoral girdle. It is situated on the lateral side, which extends outwards from the main axis.
Let’s now find a solution from the options given:
Upper Arm: A pair of forelimbs are present in humans. Each forelimb consists of 30 upper, lower and lower bones. The humerus is a single long bone in the upper arm.

Lower arm: ulna and radius are bones in the lower arm. These two bones may be crossed or parallel to each other. The radius is shorter than the ulna.
The lower jaw (mandible) supports the lower row of teeth and gives form to the lower face and to the chin. It's the bone that swings when the mouth opens and closes. The upper jaw (maxilla) contains the upper teeth, forms the middle of the face, and protects the nose.
Thigh: A pair of hind limbs are present in humans. There are 30 bones in each hind limb that make up the hip, shank, knee, and foot. The longest and strongest bone in the thigh is called the femur.

So the correct answer is option A - Upper arm.

Note: The hand consists of 27 bones, 8 bones in the wrist region, 5 bones in the pain region, and 14 bones in the fingers. The 8 wrist bones are called carpals, the 5 palm bones are called metacarpals, the 14 finger bones are called "phalanges".
