Question

When a joint allows restricted movement in one plane only, it is known as a-
a) Hinge joint
b) Gliding joint
c) Angular joint
d) Pivot joint

Answer 1

Hint: Joints in the human body are used to connect two bones together. Almost all joints are movable allowing bones to move. While some are immovable. Cartilage covers the bones in the joint part. If a joint would not have been present the bones won’t have any movement. Several joints are present in human body let us discuss about that-

Complete answer:
Option A: Hinge joint- in hinge joint the movement will be from one side like a door the other part or side of the joint is fixed. Example- elbow joint.
Option A is the correct answer.
Option B: Gliding joint- gliding joint is also known as planar joint is a type of synovial joint between bones which provides flat surfaces.
Option B is not the correct answer.
Option C: Angular joint- the joint which is movable in a particular angle or certain angle type is called an angular joint.
Option C is not the correct answer.
Option D: Pivot joint- pivot joint has a cylindrical shaped bone which contains a ring inside the joint.
Option D is not the correct answer.

Hence, Option A is the correct answer.

Note:
There are several joints in the body named as- ball and socket joint which is present in hip and shoulder joints. They show backward and forward movements. Hinge and pivot joint we had discussed. There are other joints like- the Saddle joint, the Condyloid joint and the Ellipsoidal joint. The strongest joint in the body is the Hip joint. It has the strongest ligaments and muscles making it the strongest joint in the body.
