Chemicals that facilitate the movement of impulses at synapses?

∙ 13y ago
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.

Message sent by releasing chemicals that jump across synapses involve?
transformations
How does a message jump across the synaptic gap and passes to the next neuron?
Nerve impulses, which are electrical, do not jump across the synaptic gap at synapses. Instead, the arrival of a nerve impulse at the axon terminal triggers the release of chemicals called neurotransmitters from the axon terminal into the synaptic gap, the nerve impulses then travel across the chemicals to the place where it needs to go to
What part in the nervous system moves?
Its the impulses sended from neuron to neuron via synapses... it can travel within a fraction of second which helps us to escape from dangers rapidly...
Describe how transmission of impulses across synapses can be controlled?
They can be controlled by neurotransmitter levels, function, and by pre- and postsynaptic receptors, as well as by their component messengers and intermediaries (such as cyclic AMP and others).
Where do nerve impulses travel?
Nerve impulses travel up through nerves, into the spinal cord and into one of the different lobes of the brain depending on where the impulse comes from. For example, if the impulse comes from your ear, the impulse would travel to the temporal lobe.
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.
Part of a neuron that conducts nerve impulses?
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.
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.
Message sent by releasing chemicals that jump across synapses involve?
transformations
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.
