Nerve/command signals are sent from one place to another in the body through conductors called nerve fibers. These conductors can hand-off/relay these signals to other nerve fibers, or to organs, such as muscles, that take action on the command. Neurotransmitters are chemical substances located where the nerve hands off these signals. They enable the signal to pass the nerve carrying the signal to the receiving fiber.
What else can I help you with?
Where are neurotransmitters found in the body?
Neurotransmitters are found in the brain and the nervous system throughout the body. They are stored in vesicles at the end of nerve cells and are released into the synapse to transmit signals between neurons.
Based on the main neurotransmitters the sympathetic nervous system can be classified as what?
The sympathetic nervous system can be classified as adrenergic, based on the main neurotransmitters used.
What system in the body releases neurotransmitters?
The Central Nervous System.
From where are neurotransmitters secreted?
Neurotransmitters are secreted from the axon terminals of neurons in the brain and nervous system.
How are signals transmitted using neurotransmitters in the human nervous system"?
Neurotransmitters are chemicals that carry signals between nerve cells in the human nervous system. When a nerve cell is stimulated, it releases neurotransmitters into the synapse, the gap between nerve cells. These neurotransmitters then bind to receptors on the receiving nerve cell, triggering a response and transmitting the signal. This process allows for communication and coordination within the nervous system.
Which subdivision of the autonomic nervous system operates using the neurotransmitters norepinephrine and epinephrime?
sympathetic
What is a system of membrane channels?
In the nervous system the system of membrane channels is called the neuroreceptors. Neurotransmitters use the neuroreceptors as binding sites.
Do neurotransmitters form the myelin sheath?
No, not at all. The myelin sheaths are actually made by other living cells in the nervous system known as glia. Two types of glia myelinate the nervous system: oligodendrocytes and Schwann cells. The oligodendrocytes for myelin in the central nervous system (brain and spinal cord) and the Schwann cells form myelin in the peripheral nervous system (everything outside the brain and spinal cord).
Are chromosomes composed of neurotransmitters?
No, chromosomes are structures found in the nucleus of cells that contain genetic material in the form of DNA. Neurotransmitters are chemical messengers used by neurons to transmit signals across synapses in the nervous system. They are not directly related to chromosomes.
What will happen to a person if his neurons fail to produce neurotransmitters?
The nervous system can't transmit messages without neurotransmitters. A person will die if his neurons fail to produce them.
What is a system of membrane channels called?
In the nervous system the system of membrane channels is called the neuroreceptors. Neurotransmitters use the neuroreceptors as binding sites.
How is information processed and transmitted in the nervous system?
It is transmitted along action potentials by way of chemical neurotransmitters.
