Nerves transmit messages through electrical impulses known as action potentials. When a nerve is stimulated, ion channels in its membrane open, allowing sodium ions to flow in, which depolarizes the membrane. This change in voltage triggers adjacent ion channels to open, propagating the impulse along the nerve fiber. Once the impulse reaches the end of the nerve, it typically causes the release of neurotransmitters, which transmit the signal to the next nerve or target cell.

How are messages from the femoral nerve sent to the brain?
Messages from the femoral nerve are sent to the brain through a series of electrical impulses. These impulses travel along the nerve fibers of the femoral nerve until they reach the spinal cord, where they are then transmitted up to the brain via the spinal cord's sensory pathways. Once in the brain, the messages are interpreted and processed to produce a response or sensation.
What nerves carries messages of sound to the brain?
The auditory nerve, also known as the vestibulocochlear nerve, carries messages of sound from the inner ear to the brainstem and then to the brain where sound is processed and interpreted.
How does a nerve cell function in a human?
The function of a nerve cell is to carry messages around someones body. To adapt to their job, they're very long and are branched at each end. Nerve cells also receive, carry and pass electrical impulses through someones body.
Messages are carried from the eyes to the brain by?
Messages are carried from the eyes to the brain by the optic nerve. The optic nerve is responsible for transmitting visual information to the brain for processing and interpretation.
How do nerves send messages along their length?
Nerves send messages along their length through a process called action potentials. When a nerve cell is stimulated, ion channels in its membrane open, allowing sodium ions to flow in, causing a rapid change in the electrical potential across the membrane. This electrical signal travels along the axon of the nerve cell, and when it reaches the end, it triggers the release of neurotransmitters that transmit the signal to the next nerve cell or target tissue. This process is facilitated by the myelin sheath, which insulates the axon and speeds up signal transmission.
What transmits messages between nerve cells?
Nerve messages pass from the axon of one nerve into the dendrite of another through a space separating them called the synaptic cleft.
How are nerve impulses initiated and transmitted?
Nerve impulses are initiated and transmitted according to nerve reactions and messages that get passed along or transmitted along nerve synapses and zones.
These cells are able to pass messages back and forth?
Neurons are the cells responsible for sending and receiving messages in the nervous system. They can pass messages back and forth by transmitting electrical signals along their length and releasing chemical messengers called neurotransmitters at the synapses to communicate with other neurons or target cells.
How does an action potential pass along a nerve?

Which direction do messages pass down the nerve cells?
Nerve impulses are carried by neurons and passed to other neurons at junctions called synapses. cells pass messages The signal may be directly transferred or can be carried across the gap by chemicals called neurotransmitters.
How do nerves pass along messages throughout your body?
They send the messages along some cords ing your body from the brain to where ever, and then you do what they say.
What do nerve agents do?
Nerve Agents are also known as nerve gases. They disrupt the mechanism by which nerves transfer messages to the organs. ---- More specifically, nerve agents interfere with the transmission of messages along nerves, interfering with the chemical interactions that pass a message from one end of a nerve cell to the next nerve cell. They disrupt the electro-chemical processes at the synapses (junctions between nerve cells) by blocking acetylcholinesterase, a key enzyme. By inhibiting nerve message passing, they prevent key messages from being sent to various critical body functions. As such, they cause involuntary muscle spasms in increasing intensity, and eventually lead to fatal asphyxia as the loss of respiratory control progresses.

Why do messages not get mixed up passing through the spinal cord?
There are ascending and descending tracts in the spinal cord. These tracts are nerve fibers bundled together. Messages going to the brain pass through the ascending tracts while messages coming from the brain pass through the descending tracts. These separate paths prevent messages from getting mixed up.
What happens to your nerve?
As a nerve the nerve begins to bring messages through out the body
What is the high-speed signals that pass along the axons of nerve cells called?
The high-speed signals that pass along the axon are called action potentials. They spread in a wave of depolarization.
