What are electrical impulse sensors called?
Electrodes
What is the brief electrical impulse transmitted along the axon called?
Butter Steak.
How are hormones similar to neurotransmitters?
A neural impulse is similar to an electrical signal in three ways: 1. there are electrical voltages involved in the movement of the neural impulse; 2. an electrical signal can convey information, as can a neural impulse; 3. an electrical signal can cause an action, like a car starter switch starting the engine, and a neural impulse can cause a muscle to contract to move a limb. (note that with respect to the voltages involved in the neural impulse, the voltages are created by the movement of chemicals, charged particles called ions, somewhat similar to how batteries produce voltages.) (also note that the neural impulse is the signal which moves along the axon, as an action potential.)
When the heart stops beating because of interference of its electrical impulse it results in a condition called?
Cardiac Arrest.
What connects the motor neurons to the sensory neurons?
What connects sensory and motor neuron is the impulse called interneuron or connector neuron are connected by means of electrical impulse called synape from sensory to motor neuron.
What is the minimal impulse that can initiate a muscle contraction?
Threshold stimulusThe minimal level of stimulation required to cause a fiber to contract is called the THRESHOLD STILULUS.
What is meant by impulse?
impulse is also called as sudden force or energy and called sudden shock impulse = force * displacement
How is the message caried from one neuron to another it there is a space between them?
The synaptic gap is the space between the dendrites of one neuron and the axon of the next. The impulse is carried across this space by chemicals called neurotransmitters which conduct the electrical impulse.
What is it called when a muscle contract involuntarily?
A twitch is when only one muscle is affected, usually the result of a nerve impulse, while a spasm is when multiple muscles contract involuntary, due to a chemical imbalance.
Atrioventricular node at the bottom of the?
The heart beats regularly because it has it's own pacemaker. The pacemaker is a small region of muscle called the sinoatrial, or SA, node. It is in the upper back wall of the right atrium. The node triggers an impulse that causes both atrium to contract. Very quickly, the impulse reaches the atrioventricular, or AV, node at the bottom of the right atrium. Immediately, the atrioventricular node triggers an impulse that causes both ventricles to contract.
What is impulse votage?
Sudden rise in Voltage is called Impulse voltage.
Define rated impulse voltage?
Simply, the voltage which is withstand by the test object as an impulse is called as rated impulse voltage.
