Question

What will happen if – There are no joints in the body?

Answer 1

The connection between bones in the body that links the skeletal system into a functioning whole is known as a joint or articulation (or articular surface). They're made to allow for a variety of degrees and types of mobility. Some joints, such as the knee, elbow, and others, are self-lubricating and nearly frictionless, allowing them to tolerate compression and high loads while continuing their functional movements.

Complete answer:
Our bodies would resemble a collection of disconnected bones if they lacked joints. We won't be able to do things like bend and stretch because we won't be able to bend and stretch. We will also be unable to move since joints are important for joining the bones and making the skeleton flexible.
Our body would lose its structure and form if there were no joints in it. The vital organs which remain protected through well connected (jointed) bones will no longer be protected.
The muscles of the body which function while remaining affixed on jointed bones will turn out to be functionless.
In the most precise form without joints in the body, the present dynamic features of human life will be lost abruptly.

Note:
The skeleton is held together by joints, which allow mobility. Joints can be classified in two ways. The first is through joint function, which is also known as range of motion. The substance that binds the bones of the joints together is the second approach to categorize joints; this is a structure-based classification. Based on the range of movement, joints can be immovable, slightly movable and highly movable while based on structure they can be fibrous, cartilaginous or synovial.
