The way nerves relay messages is a rather complex process. The simplified version is as follows: Ions are no equally distributed across across the cell membrane of the nerve cell (neuron), and this leads to an electrochemical potential difference. The inside is negative with respect to the outside. Put another way, the cell is "polarized". When ions move across the membrane, the cell can either be depolarized or hyperpolarized. This then leads to chemical transmitters either being released or not released from the neuron. The released transmitter interacts with the next neuron in the chain, and either excites it or inhibits it. Again, all the mechanisms involved in each step are very complex. This process continues and that is how chemical messages are sent from one neuron to another.
What else can I help you with?
Do nerves relay messages?
Nerves relay messages by transmitting an electrical impulse.
What are the two channels which relay the messages to and from the brain and to the body parts that will do the action?
These "channels " are actually nerves termed as Afferent and Efferent nerves usually called motor and sensory nerves.
What relays information between the spinal cord and cerebrum?
nerves.. NERVES RELAY ALL MESSAGES TO THE BRAIN WHICH THEN THE BRAIN SENDS INFORMATION BACK THROUGH THE NERVES TO THE WHOLE BODY
Which nerves carry messages from organs to brain?
Sensory nerves.
What are nerves?
nerves are also called neurons and they transport impulses(messages)
Do nerves carry messages for responses lead to the spinal cord?
Yes, nerves carry messages from sensory receptors throughout the body to the spinal cord. These messages are transmitted through sensory neurons, which relay information about stimuli such as pain, temperature, and touch. The spinal cord processes these signals and can initiate a reflex response before sending information to the brain for further interpretation. Thus, nerves play a critical role in the communication of sensory information to the spinal cord.
