Question

Given below is a diagram of the bones of the left human hind limb as seen from front. It has certain mistakes in labelling. Two of the wrongly labelled bones are :-

• A. Tibia and tarsals
• B. Femur and fibula
• C. Fibula and phalanges
• D. Tarsals and femur

Answer 1

The correct option is C Fibula and phalanges

Tibia and fibula are the two long bones located in the lower leg. The tibia is a larger bone on the inside, and the fibula is a smaller bone on the outside. The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and large toe, which possess only two.

Tarsals – a set of seven irregularly shaped bones. They are situated proximally in the foot in the ankle area. Metatarsals – connect the phalanges to the tarsals. There are five in number – one for each digit.

The femur is the only bone in the thigh and the longest bone in the body. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal.
Correct labelling of the given diagram is as follows-
