Question

When a client has poor motor control it increases his/her risk of joint pain and injury because of what two reasons

Answer 1

Answer: Poor motor control impairs;

--> the smoothness and

--> accuracy of joint movement.

Explanation:

The peripheral nervous system controls the motor system in vertebrates. The motor system also consists of two parts which includes:

--> The somatic nervous system and

--> The autonomic nervous system.

The motor neurones that carry instructions to voluntary muscles, that is, those muscles that we can control consciously, makes up the SOMATIC NERVOUS SYSTEM. These motor neurons are part of some of the spinal and cranial nerves. Their cell bodies are in the central nervous system; their nerve fibres extend all the way to the skeletal muscles

Impulses that speed along these fibres stimulate( excite) the muscles to being about the appropriate movements.

The somatic nervous system controls all skeletal movements. These movements include:

--> all voluntary actions like clapping ( which we can choose to do or not to do), and

--> control of the body equilibrium

Poor muscle control can occur due to injury, illness, or inherited disorder. An individual with poor muscle control is at a higher risk of joint pain and injury because of the damage to the motor neurones that innervates the skeletal muscles attached to joints. This is turn will lead to a decrease in the smoothness and accuracy of joint movement.
