Sensory receptors of the ear?
The cochlea; sound wave are transferred through the ear canal and vibrated the ear drum which is connected to the cochlea and amplified the sound wave. When the sound wave reached the cochlea, sound wave is converted into nerve impulse and transferred through the nerve to the brain. Receptor is a converter of stimulus to electrical nerve impulse ; cochlea converted sound wave into nerve impulse and so cochlea is the sensory receptor of the ear.
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
A Traveling wave of excitation is what you know as?
nerve signal
What one of these is not particle proton neutron alpha gamma ray or a beta particle?
The gamma ray is not a particle but is just an EM wave that transmits energy.
What does your brain do when you want to wave your hand?
It sends an impulse to the hand area to move so basically it sends impulses to tell the hand what to do cause its the command center
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.
A wave pattern travels down the length of the axon of what kind of 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.
A nerve impulse consists of a wave of?
Action Potentials

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.

Nerve impulse consists of a wave of moving away from a point of stimulation?
action potentials
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.

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.
Transmits wave of excitation?
Neurons.
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.
