Neurotransmitters the are means by which neurons communicate with one another. There are more than 30 compounds known to be neurotransmitters, and dozens of others are thought to be so. You will only find them in the peripheral nervous system as the central nervous system uses mainly electrical signals.

Where are synaptic nodes?
Synaptic nodes, also known as synapses, are found at the junctions between neurons, where communication occurs. They are located on the axon terminals of the presynaptic neuron and the dendrites or cell body of the postsynaptic neuron. These nodes facilitate the transmission of signals through the release and reception of neurotransmitters, allowing for the propagation of nerve impulses.
What are neurouns?
Neurons are specialized cells in the nervous system responsible for transmitting information throughout the body. They communicate via electrical impulses and chemical signals at synapses, enabling processes such as sensation, movement, and cognition. Neurons consist of three main parts: the cell body, dendrites, and axon, each playing a crucial role in receiving and sending signals. Together, they form complex networks that facilitate communication within the brain and between the brain and the rest of the body.
What are animal cells that are specialized for conducting electrochemical impulses known as?
Animal cells specialized for conducting electrochemical impulses are known as neurons. Neurons have unique structures such as dendrites, axons, and synapses that allow for the transmission of electrical signals within the nervous system.
What are the synases?
Synapses are specialized junctions that facilitate communication between neurons or between neurons and other types of cells, such as muscle cells. At a synapse, the presynaptic neuron releases neurotransmitters, which cross the synaptic cleft and bind to receptors on the postsynaptic cell, triggering a response. There are two main types of synapses: chemical synapses, which use neurotransmitters, and electrical synapses, which allow direct electrical signals to pass between cells. Synapses play a crucial role in neural communication, influencing processes like learning, memory, and reflexes.
Why is synapse important to the nervous system?
Synapses are important because they enable signal transmission in the body. These signals are the nerve impulses, which go across and between neurons. This process occurs in the synaptic cleft of the central nervous system.
What is the name of the chemicals that transmit impulses at synapses?
Neurotransmitters
Transmission of nerve impulses across the synapses is brought about by the secretions of very low concentrations of the chemicals known as?
neurotransmitters
How does the impulses get over the synapses?
Neurotransmitters. It's purely chemical.
What is receiving and carrying impulses towards the cell bodies?
neurons and synapses
What are the cells that transmit nerve impulses between parts of the nervous system?
yes
How do chemicals travel through the human blood?
Synapses
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.
How do depressants slow down the transmission of nerve impulses?
they stop the signals travelling down the nerves by blokcing the synapses
What is the part of the neuron that carries impulses to the body?
Synapses. Net flow of charged ions ("impulses") in neuronal cells trigger additional ion flow (ionotropic signaling) or neurotransmitter release (metabotropic signaling) to both neuronal and non-neuronal cell types ("the body") at junctions called synapses.
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.
What is synapses?
A synapse is a small gap at the end of a neuron that allows information to pass from one neuron to the next.
When acetylcholine is blocked from neuron endings what happens?
Blocking acetylcholine from neuron endings can prevent the transmission of nerve impulses across synapses. This can lead to muscle weakness, impaired movement, and other symptoms associated with conditions like myasthenia gravis or drug-induced paralysis.
