Question

Which one acts as a shock absorber to cushion when tibia and femur came together
(a) Ligament
(b) Cartilage
(c) Tendon
(d) Disc

Answer 1

Hint: It is soft, rubbery, blue-white connective tissue. It is a tissue that gives some structure with versatile support. It is a major structural feature of the body. It is a firm tissue, but it is thinner than bone and much more flexible.

Complete answer:
Shock is a physiological condition where there is not enough blood flow for both the body's organs and tissues. This deprives cells and tissues of oxygen (carried in the blood) and allows waste products to build up. Muscles avoid shock, so they typically act in pairs to move our joints. By contracting out they will show off a joint push in the opposite direction.
Let us now discover the solution from the options offered—
Cartilage is a solid connective tissue at the end of long bones such as that of the femur, tibia, and humerus, forming a pad. As a shock absorber, cartilage helps to cushion the weight of each other and provide protection from stress due to joint movement.
A connective fibrous tissue that connects the bones to other bones is a ligament. They are brittle, with an unreliable blood supply. It tends to be the crisscross bands. They are composed of thick collagen fibers, arranged in parallel coils.
A tendon is a flexible band of connective fibrous tissue that connects muscle to bone and can sustain stress.
A significant and special organ in the spine is the vertebral disk. The discs in the spine have three main functions: they act in the spine as shock absorbers, positioned in each bony vertebra.
Hence, the correct answer, therefore is choice (b), i.e., cartilage.

Note: Around the femur and the tibia, the meniscus acts as a cushion and shock absorber. That is the bent fibrous cartilage found in certain joints like the knee.
