kk4 the role of neurotransmitter in the transmission of the neural information between neurones to produce excitatory effects Flashcards
what is a synapse gap?
a synapse gap in a junction between the axon tip of the
sending neuron and the dendrite or cell body that is receiving the neuron. it can also be known as a cleft
what are receptor sites
receptor sites are the areas on the surface of receiving
neurons that are sensitive to both neurotransmitters and
hormones
what is a neurotransmitter?
Neurotransmitters are chemical messengers that transmit a signal from a neuron across the synapse to a target cell,
which can be a different neuron, muscle cell, or gland cell.
whats the lock and key process?
the lock and key process is when specific receptor sites are receiving neurotransmitter
molecules that fit perfectly into them
what happens when receptor sites receive the neurotransmitter molecules
once the receptor site receives the neurotransmitter molecules there is a chemical reaction it can result in
either an excitatory ↑effect or an inhibitory↓ effect.
whats an excitatory neurotransmitter?
an excitatory neurotransmitter is a reaction that speeds
up the neural activity and ↑increases the chances that
the excitatory signal is sent.
whats an inhibitory neurotransmitter?
an inhibitory neurotransmitter is a reaction where it
slows down the process of neural activity and decreases
↓the chances of the inhibitory signal sent
what do inhibitory neurotransmitters include?
it includes aminobutyric acid.
It is the major inhibitory neurotransmitter in the CNS and plays a major role in regulating anxiety and reducing stress
It improves mental focus while calming the nerves.
