Question

Number of bones in hind-limb of human is
(A). 21
(B). 24
(C). 30
(D). 14

Answer 1

The lower consists of high region, leg region and foot region. The femur, or thigh bone is the longest and strongest bone of the body. Femur joins the patella. Tibia is the medial bone of the leg and is larger than the fibula, with which it is paired. The posterior half of the foot is formed by seven tarsal bones. The mid foot has meta- tarsal bones and the toes contain the phalanges.

Complete answer:
The human body consists of around 210 bones, depending upon the counting of sternum, this may range from 206 to 210 bones. The bones of the limb along with their respective girdles constitute the appendicular skeleton. The hind-limb contains the following bones :- Femur( the longest bone ), Tibia, Fibula, Tarsal, Metatarsal, Patella and Phalanges. Counting the number of bones, these are
Femur $\to$ 1
Fibula $\to$ 1
Tibia $\to$ 1
Patella $\to$ 1
Tarsals $\to$ 7
Metatarsals $\to$ 5
Phalanges $\to$ 14
Thus, the Hind-limb of humans consists of a total 30 bones.

So, the correct answer here is option (C).

Note:
Limbs are very important for processes like walking, running or climbing.
The lower limb is divided into three regions. The thigh is that portion of the lower limb located between the hip joint and knee joint.
Some interesting facts about hind-limb are:-
(a). Fovea capitis is depression in the head of the femur.
(b). Femur is the longest and strongest bone of the body.
(c). Patellar groove is found in the distal end of femur.
(d) Phalanges formula = 2,3,3,3,3
(e). Thumb of the foot is called hallux.
