The nerve impulse travels through and reaches the threshold potential which opens Na+ Channels in the cell membrane. The Na+ ions diffuse into cell. The charges reverse at that point on the neuron, and which the cell becomes depolarized.

What does the brainstem do a part from sending messages to the body?
It controls the axis and atlas which is connected to your vertebrae. This allows your head to move up and down and also right to left. It helps you move youre body in many directions and controls sending messages throughout your entire body.
What is the difference between motor and sensory neurons?
The main difference is that motor neurons move signals away from the central nervous system and spinal cord where as sensory neurons move signals towards the central nervous system and spinal cord.
How does movement of electrical impulse relate to the contraction of the chambers of the heart?
The impulse shocks the left and right atria of the heart. This pumps blood into the left and right ventricle. The ventricles then receive the impulse and pump the blood. The movement of the electrical impulse allows the blood to move through multiple areas of the heart with only one impulse.
Where are the sensory and motor cortex located?
The motor cortex is in the frontal lobe of the brain whilst the sensory cortex is in the parietal lobe. Another main difference is that the motor cortex controls movements of fine and gross motor skills whereas the sensory cortex controls feelings of touch and sensation.
When you want to move your arm your brain sends a message where does the message go?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineEach nerve impulse begins in the dendrites of a neuron's. the impulse move rapidly toward the neuron's cell body and then down the axon until it reaches the axon tip.a nerve impulse travels along the neuron in the form of electrical and chemical signals.Acetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction.
How does the skeletal system interact with the sensory system?
The skeletal system is the framework of the human body and holds up the other body parts in place. When the sensory, or nervous, system uses the muscular system to move the body, the muscles move the skeleton as well.

Can you define an impulse movement in dance?
An impulse move in dance is when the dancer "tweaks" his or her body suddenly. These movements look like sudden jerks or twitches.
How do muscles vary throughout the body?
Muscles vary throughout the body by voluntary and involuntary, voluntary is the muscles you can move and involuntary is the muscles you can't move.
What is the difference between motor and sensory neurons?
The main difference is that motor neurons move signals away from the central nervous system and spinal cord where as sensory neurons move signals towards the central nervous system and spinal cord.
What are the advantages of being bilaterally symmetric?
sensory organs at the front of the body and more streamlined (can move faster)
What do sensory seizures consist of?
Sensory seizures begin with numbness or tingling in one area. The sensation may move along one side of the body or the back before subsiding.
What is metastasized?
Cancer that can move throughout the body and spread to other organs
Which part is forced to move blood throughout the body?
Veins and arteries
What is a response caused by the spinal cord interpreting an impulse from sensory receptors?
The only response by the spinal cord is not an interpretation but a reflex. A sensory impulse comes in and at the cord a reflexive arc occurs taking information to muscles or glands. The brain does the interpretation. You touch a hot stove and that info goes to the spinal cord which causes a reflexive action where the muscles move the hand away. All that happens before the brain gets an "incident report".

Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
