Question

Patella groove is found on which bone of the following?
A. Femur
B. Tibia-fibula
C. Depression between femur and tibia-fibula
D. Tarsus

Answer 1

Hint: The hard, supportive or protective structure of the human body constitutes the skeletal system or skeleton. The skeleton which is external is called the exoskeleton and the skeleton which is present inside the body is called the endoskeleton. The endoskeleton consists of a framework of bones and a few cartilages.
Bone is a hard connective tissue in which the ground substance is very hard and contains calcium salts. The ground substance has enormous irregular spaces, called lacunae, in which the osteocytes are present.

Complete answer:
 Human skeleton consists of 206 bones. Bones provide the framework to our body. There are a total of 60 bones in our legs.
Femur is the longest bone of the body. It is present in the thigh. Its upper end has a rounded head, a constricted neck and a greater trochanter. The head of the femur articulates into the acetabulum of the pelvic girdle. There is a long shaft. The lower end is divided into two condyles. Patella (knee cap) is a flat, triangular, sesamoid bone which anteriorly articulates with the condyles of the femur. Patella is attached with quadriceps tendons proximally and to the patellar tendon distally.
Tibia and fibula are present in the lower leg. Tibia is longer and thicker, and lies more medially and forwardly while fibula is shorter and thinner, and lies more laterally and deeply. There are 7 tarsals present in the ankle and 5 metatarsals present in the sole. So, the patellar groove is not present on the tarsus bone.

So, the correct answer is “Option A”.

Note:
The bones of legs are the part of the appendicular skeleton and support the muscles of lower limbs and help in standing, running, walking, etc. these bones are strong because they support the weight of the whole body.
The bones strengthen the legs to bear body weight, to balance the body while standing and to aid in locomotion.
