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).

Chemicals that facilitate the movement of impulses at synapses?
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.
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 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...
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 part of a neuron transmits information to other neurons?
Dendrites receive information from other neurons. A dendrite is a short branched extension of a nerve cell where impulses received from other cells at synapses are transmitted to the cell body.
Transmission of nerve impulses across the synapses is brought about by the secretions of very low concentrations of the chemicals known as?
neurotransmitters
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 name of the chemicals that transmit impulses at synapses?
Neurotransmitters
How does the impulses get over the synapses?
Neurotransmitters. It's purely chemical.
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.
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 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 the nerves transmit signals to the brain?
Nerves use electrical impulses to transmit signals to the brain. The gaps between the nerve endings are called synapses.
