Question

The finger bones do not have joints.
A) True
B) False

Answer 1

Hint: PEN created in the process of double fertilization in the angiosperms (flowering plants). This cell later develops into the endosperm, which is the main source of nutrition for growing embryos.

Complete answer:
Our body consists of many joints which enable a range of movement. For example – joints are present in our wrist, knee, elbow, etc.
There are also some kind of joint which does not allow to move. For example – joints between the bones of cranium.
Our fingers also consist of joints.
Finger joints:
Each of the fingers has three joints. That are:-
>Metacarpophalangeal joint (MCP)
>Proximal interphalangeal joint (PIP)
>Distal interphalangeal joint (DIP)
Metacarpophalangeal joint(MCP):
Metacarpophalangeal joint is the joint at the base of the finger.
This joint is located where the hand bone meets the finger bone.
And this joint is referred to as ‘Knuckle’.
These joints are too important because they allow us to bend and spread our fingers.
Proximal interphalangeal joint(PIP):
Proximal interphalangeal joint is the joint in the middle of the finger.
This joint is located between the two bones of the finger.
This allows the finger to bend and extend.
Distal interphalangeal joint(DIP):
Distal interphalangeal joint is the joint closest to the fingertip.
This joint is located at the fingertip just before the fingernail starts.

So, in the above discussion we have seen that each finger has three joints. So, the above statement i.e. finger bones do not have joints is incorrect.

Hence, option B is the right answer for this question.

Note:The joints present in the finger allow us to have several kinds of movement. Without these joints one can not hold anything, cannot write, in short he/she will be unable to move, bend or extend his/her fingers.
