A cricket player is fast chasing a ball in the field. Which one of the following groups of bones are directly contributing in this movement
Femur, malleus, tibia, metatarsals
Pelvis, ulna, patella, tarsals
Sternum, femur, tibia, fibula
Tarsals, femur, metatarsals, tibia
D.
Tarsals, femur, metatarsals, tibia
Tarsal- Tarsal, any of several short, angular bones that in humans make up the ankle and that—in animals that walk on their toes (e.g., dogs, cats) or on hoofs—are contained in the hock, lifted off the ground. The tarsals correspond to the carpal bones of the upper limb.
Femur- Femur, also called thighbone, or hind leg. The head forms a ball and socket with the hip (at the acetabulum), being held in place by a ligament (ligamentum teres femoris) within the socket and by strong surrounding ligaments.
Metatarsals- Anatomical terms of bone. The metatarsal bones, or metatarsus are a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes
Tibia- The tibia, also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertiberates (the other being the fibula, behind and to the outside of the tibia), and it connects the knee with the ankle bones.
Given diagram shows bone of the left human hindlimb as seen from front. It has certain mistakes in labeling. Two of the wrongly labelled bones are
tibia and tarsals
femur and fibula
fibula and phalanges
tarsals and femur
