What is the name for the impulse generated when a neuron fires?
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
Sensory receptors of the ear?
The ear contains sensory receptors such as hair cells in the cochlea, responsible for detecting sound waves, and the semicircular canals, which detect changes in head position and movement to help with balance. These receptors convert physical stimuli into electrical signals that are transmitted to the brain for interpretation.
A Traveling wave of excitation is what you know as?
A traveling wave of excitation is commonly known as an action potential. It is a brief electrical impulse that travels along the length of a nerve cell or muscle fiber, allowing for rapid communication and coordination within the body.
The point at which an impulse from one nerve cell is communicated to another nerve cell is what?
The point at which an impulse from one nerve cell is communicated to another nerve cell is called a synapse. This is where neurotransmitters are released from the presynaptic neuron, cross the synaptic cleft, and bind to receptors on the postsynaptic neuron, transmitting the signal.
What is the first wave of an ECG?
I believe it is the P Wave. A good way to remember is all of the Waves are in alphabetical order. P Wave, Q-R-S Waves and the T Wave
What A wave pattern travels down the length of the axon of a cell.?
A wave pattern travels down the length of the axon of a nerve cell. A nerve cell, also called a neuron, is a specialized cell that transmits nerve impulses.

What is impulse in the nervous system?
electrical wave conducted along the nerve generated by the voltage difference across the cell membrane of the nerve cells.

Write note on nerve impulse?
A nerve impulse is an electrical signal that travels along nerve cells, allowing for communication between different parts of the body. It is generated when there is a change in the voltage across the cell membrane, causing a wave of depolarization and repolarization to propagate down the length of the neuron. Nerve impulses play a crucial role in various bodily functions, including movement, sensation, and communication between the brain and other organs.
The events of a nerve impulse?
The electrical impulse in a nerve cell begins when ions move through the cells surface through ion channels.The nerve impulse.A nerve impulse is a wave of excitation that quickly travels within the surface of a neurone (nerve cell). This nerve impulse usually travels on certain parts of the nerve cell: on a dendrite or an axon. Within a neurone the first event depends on the type of 'nerve impulse'; there are two important types:1- nerve impulses generated at dendrites2- self propagating nerve impulses (action potentials) that travel along the axonNerve impulses generated at dendrites.Dendrites feed into the 'cell body' (soma) of a neurone. Nerve impulses that are generated in these dendrites travel toward the cell body.A sequence of events occur at the surface of a dendrite when the nerve impulse is sparked. The first event is transduction; this involves the transformation of one form of energy outside the dendrite into electrical energy within the dendrite.Nerve impulses that travel along axons.Nerve cells often have many dendrites but often only have a single axon. The essential difference between the two parts of the nerve cell is:- in dendrites electrical impulses travel TOWARDS the cell body of the neurone- in the axon the electrical impulses travel AWAY from the cell body of the neuroneThe nerve impulse that travels along an axon begins at the 'base of the axon', where the cell body and axon merge. This site is called the 'axon hillock' and is found to be the site where the first event in the formation of a nerve impulse actually occurs. Again, the first event is transduction at the axon hillock.Conclusion; the first event.For both of the cases above, and for virtually any other case, the nerve impulse begins with a process of transduction. The electrical nerve impulse begins once the first 'ions' leave or enter the nerve cell. Usually sodium ions enter, sometimes calcium ions are the firs to enter, sometimes potassium ions are the first to leave.
Traveling wave of excitation is known as?
Traveling wave of excitation is known as an action potential in nerve cells or an impulse in muscle cells. This wave allows for communication and coordination of cell activities in the body.
Why you hear a sound when you clap your hands together.?
the hands make a compression wave that travels through the air. Your ears pick up that compression wave and turns it into a neuron impulse that your brain registers as sound.
Sensory receptors of the ear?
The ear contains sensory receptors such as hair cells in the cochlea, responsible for detecting sound waves, and the semicircular canals, which detect changes in head position and movement to help with balance. These receptors convert physical stimuli into electrical signals that are transmitted to the brain for interpretation.

How is nerve impulse conducted along a myelinated nerve fiber?
In non-myelinated axons, the nerve impulse is going to be produced when the action potential accross a membrane makes a wave of depolarization followed by a wave of repolarization. With the absence of the myelin, the impulse is transmitted continuously throughout the membrane. In a non-myelinated nerve, once an end of the cell, the dendrite, is depolarized, the depolarization a.k.a., the action potential, moves along the nerve membrane, and the area of membrane immediately behind the depolarized section becomes repolarized.
