What part of the eye sends the image through an electrical impulse to the brain?
Light rays reflect off the object and into the eye where they are refracted by the cornea and focussed by the lens on to the retina, the optic nerve then carries the messages to the brain and an image is formed.
Where does a motor neuron send its message?
The Motor in an abafatirc muscle so it sends an inpluse to the heart
When a single neuron sends a strong enough impulse to a muscle that how many muscle fibers does it cause to contract?
This will depend upon the number of muscle fibers the nerve innervates. However, all fibers innervated by the nerve should contract in response to the neuronal impulse.
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.
What regulates the pituitary glands?
The brain. It sends chemicals to the pituitary gland to activate all that puberty stuff
What does a pacemaker control in the heart?
A pacemaker sends electrical shocks to the heart to beat it at a particular speed. It pulsates the heart at a set rate (eg. 60bpm) to help those who are have a slower than normal heartbeat.
How does your heart pump?
The AV node sends out an electrical impulse that causes the heart to contract.
The purpose of defibrillation is to?
It is to "restart" the heart's electrical conductivity and electrical rhythym. It, in general, sends out an electrical impulse to the heart to kickstart it.
What sends an impulse to a muscle or gland?
axon
Structure that carries the heart electrical impulse into the ventricle?
The atrioventricular (AV) node sends the signal to the AV bundle, where the wave of contraction travels from the atria to the ventricles.
What monitors muscle length and sends an impulse to the spinal cord to initiate the stretch reflex?
What monitors muscle length and sends an impulse to the spinal cord to indicate the stretch reflex
How does a shark find food?
It uses its incredible sense of smell more then anything. Some sharks especially hammerheads have a sixth sense that helps locate food on the ocean floor. It sends receives electrical signals sent out into the ocean by other fish. When ever a heart beats it send out an electrical impulse some fish can pick up on this electrical impulse to better target their food.
Does blood kept your heart going?
Nope, your heart pumps in a rythym due to automatic electrical impulses sent from your hypothalamus (reptillian brain) to a node (Sinoatrial) in the atrial wall (heart muscle), this node in turn sends the impulse to the atrioventricular node which makes the muscle cells in the rest of the hear contract, the noise of your heartbeat is these two seperate contractions which happen close together
An electrical signal causes the atria to?
bubble up and popno one knowsthe signal causes the atria to contract.
Application of feedback control system in electrical?
One application of feed back control is where the speed of a motor has to be maintained at a certain RPM and the load it drives is variable. Feedback from the load tells the VFD (Variable Frequency Drive) motor controller what to do. As the load drags the motor speed down the feedback unit sends a electrical impulse to the VFD to increases the speed of the motor. As the load drops off the feedback unit sends a electrical impulse to the VFD to decreases the speed of the motor. These interactions keep the motor RPM at a constant speed. This is a very simplified version of what happens.
What is an excitable nerve cell that sends electrical signals?
A neuron is an excitable nerve cell that sends electrical signals when stimulated
What statements characterizes an excitatory neuron?
It sends an impulse back to the cell body of the neuron
