The joint which help in movement in all directions is:
A.Pivotal joint
B.Ball and socket
C.Hinge Joint
D.Fixed Joint
Solution
Synovial joints which are present between two adjacent bones allow the maximum movement in the body. Fixed Joints are the one which does not allow any movement. The Joints which are capable for forward, backward, sideways and rotating movements are the one which allow all type of movement.
Complete answer:
The point at which two or more bones meet is called a joint, or articulation. Joints are responsible for limb movement, and body stability. There are many types of joints, including joints that don’t move. The joints which do not show any movement are called "fixed" or "immovable" joints. These types of joints do not have joint cavities and are connected by fibrous connective tissue. The skull bones are connected by fibrous joints and are a type of fixed joint.
Hinge joints are the ones which allow movements in only one direction such as in the fingers, knees, elbows, and toes, which allow only bending and straightening movements. A pivot joint is a type of synovial joint in which the axis of a convex articular surface is parallel to the longitudinal axis of the bone. It allows a certain type of rotational movement.
Ball-and-socket joints have a rounded, ball-like structure at an end of one bone fitted into a cuplike socket of another bone. This organization allows the maximum type of motion, as all movement types are possible in all directions. Examples of ball-and-socket joints are the shoulder and hip joints
Hence, the correct answer is option (B)
Note: A joint is the connection made between two bones in the body which are connected with each other as the skeletal system into a functional whole. Joints are categorized based on their structural
