Smooth muscle. You use smooth muscle to help digest food
Answer: PARALYSIS
Explanation: Paralysis is a nervous system disorder that is characterised by a complete or partial loss of muscle function.
It is caused by either stroke or spinal cord injury which affects the normal functioning of muscles and nerves in the body.
Paralysis can also be caused by accident of trauma to any of the structures of the nervous system which in turn affects the nerves or muscles.
It can also be caused by a damage to the chain of nerves and muscles that deliver impulses to and from the brain and spinal cord to the nerves and muscles.
When the brain,spinal cord or nerves is damaged by any of the causes mentioned above,the relay signal to the muscles and nerves is damaged or altered,so the signal for one to move do not make it through to the muscles and this results to paralysis.
So Joseph suffers from a loss of of sensation and movement due to injury to his nervous system. He is therefore experiencing PARALYSIS.
True.
A neuron is nerve cell. It is considered the functional unit of the nervous system and it carries electrical impulses to the appropriate part of the nervous system or interprets the impulse and allows a response.
The electrical impulse or message is carried through the fibrous extensions of the neuron called dendrites to the cell body. It passes through the cell body via the axon and finally to the end brush , a collection of fibers that extend off the axon.
The electrical impulse then triggers a release of chemicals which permit the impulse to jump through the synapse, the space between the axon of one neuron and the dendrites of the next neuron.
