Question

Sometimes , while eating we bite our own fingers or tongue by mistake ? Justify​

Answer 1

The answer is:

Explanation:

• While eating a coordinated movement occurs between the muscles of the tongue, muscles of the jaws, and the muscles of the hand.
• These movements are simultaneously mediated by the motor neurons that bring the impulse for contraction and relaxation from the brain or spinal cord to these muscles at the appropriate time.
• But at times, due to lack of concentration on eating or operation of different thoughts in the brain there can be a disturbance in this coordinated cumulative movement.
• This can cause us to bite our own fingers or tongue.
