When you speak, your brain sends a signal to your vocal cords, which vibrate to create sound. This signal travels down your throat, through your chest and into your lungs. The air pressure created by your lungs forces the sound out of your mouth.
The sound waves travel through the air and hit your listener’s ears. Inside the listener’s ear, the sound waves cause the eardrum to vibrate. This vibration is transmitted to the middle ear, where it causes the tiny bones to vibrate. This vibration is transmitted to the inner ear, where it causes the fluid in the cochlea to vibrate. This vibration is transmitted to the brain, where it is interpreted as sound.

How does a signal travel through a neuron?
A neuron is a specialized cell in the nervous system that transmits electrical impulses. These electrical impulses allow the neuron to communicate with other neurons and muscles. The signal that travels through a neuron is called an action potential.
The action potential begins when the neuron receives a signal from another neuron. This signal is called a synaptic potential. The synaptic potential causes the neuron to become electrically excited. This electrical excitement causes the neuron to generate an action potential.
The action potential travels down the neuron’s axon. The axon is a long, thin fiber that extends from the neuron’s cell body. The action potential travels down the axon at a speed of about 120 miles per hour.
Near the end of the axon, there are specialized structures called axon terminals. The axon terminals are in contact with other neurons or muscles. When the action potential reaches the axon terminals, it causes the release of neurotransmitters.
The neurotransmitters travel across the synaptic cleft and bind to receptors on the other neuron. This causes the other neuron to become electrically excited and generate its own action potential.

How does a signal travel down a neuron quizlet?
A neuron is a type of cell found in the nervous system. It has a long, thin extension called an axon, which sends signals to other cells. The signals travel down the axon as electrical impulses.
At the end of the axon is a structure called a synaptic terminal. This is where the signals are received by other cells. There are special structures in the synaptic terminal called receptors, which bind to the signals and pass them on to the cells.
The signals travel from the receptors to the cells’ nucleus, where they are interpreted and acted on. This process allows the cells to communicate with each other and coordinate their activities.
How a signal travels down an axon?
When you speak, your brain sends a signal down your spinal cord to the muscles in your throat, which vibrate to create sound. That signal travels down your axon, a long, thin nerve cell, to your vocal cords.
Axon:
The axon is a long, thin nerve cell that carries signals from the brain to the rest of the body. It’s covered in a protective layer of myelin, which helps it to transmit signals quickly and efficiently.
Vocal Cords:
The vocal cords are a pair of thin muscles in the throat that vibrate to create sound. They are controlled by the muscles in the neck and the brain, and they can be used to produce a wide range of sounds.
How do impulses travel across a synapse?
How do impulses travel across a synapse?
A synapse is a junction between two nerve cells, where the signal transmission between the cells occurs. The impulse or signal is transmitted from the first cell, or the pre-synaptic cell, to the second cell, or the post-synaptic cell. The impulse is transmitted as a rapid change in the electrical potential across the cell membrane.
The impulse is transmitted across the synapse through the release of neurotransmitters from the pre-synaptic cell. The neurotransmitters bind to receptors on the post-synaptic cell and this triggers the changes in the electrical potential across the cell membrane.
The changes in the electrical potential cause the release of neurotransmitters from the post-synaptic cell. This in turn, triggers the changes in the electrical potential across the membrane of the pre-synaptic cell, and the impulse is transmitted to the next cell.
What is the signal that spreads down the axon of a neuron called?
The signal that spreads down the axon of a neuron is called a nerve impulse or action potential. The impulse is a brief electrical charge that travels down the axon at speeds of up to 250 miles per hour. The nerve impulse is created when the voltage across the neuron’s membrane suddenly changes. This change in voltage is caused by the flow of positively charged ions, or atoms with a net positive charge, into the neuron.
In what order does a neuron signal travel quizlet?
In what order does a neuron signal travel?
A neuron signal travels from the dendrite, to the cell body, to the axon hillock, and finally to the axon. The signal is then transmitted down the axon to the next neuron.
How does a neural signal travel from one neuron to another quizlet?
How does a neural signal travel from one neuron to another quizlet?
A neural signal is transmitted from one neuron to another through a process called synaptic transmission. This occurs when the axon of one neuron releases neurotransmitters into the space between it and the dendrite of the next neuron. The neurotransmitters bind to receptor proteins on the dendrite and initiate a electrical signal that travels down the neuron to the cell body and then to the axon of the next neuron.
