Describe Synapses And Synaptic Transmission Flashcards
How many directions can a synaptic transmission travel?
Synaptic transmissions only travel in one direction.
What are transmissions carried by?
They are carried by neurotransmitters which are biochemicals
What occurs when the nerve impulse reaches the synaptic knob?
When the impulse reaches the synaptic knob the synaptic vesicles release neurotransmitters.
What occurs to these neurotransmitters?
They diffuse across the cleft to react with certain receptors located in the postsynaptic neuron membrane. This in turn excites or inhibits a postsynaptic cell.
What is the purpose of a nerve pathway?
The nerve pathway carries nerve impulses.
What is a synapse?
A synapse is a junction between any two communicating neurons.
The gap between two neurons is called?
The gap between two neurons is called the synapse gap.
What is the name given to a neuron carrying an impulse into a synapse?
This is a presynaptic neuron.
What is the name given to a neuron receiving an impulse?
This is called a postsynaptic neuron.
What is the process of an impulse crossing a synaptic cleft called?
This is called a synaptic transmission.
Can neurons function as both presynaptic and post synaptic neurons?
In most cases, yes.
What is an axodendritic?
An axodendritic synapse are those between axons a neuron dendrites. Of other neurons.
What is an axosomatic synapse?
This is a synapse between axon endings of one neuron and cell bodies of another.
What is a neuromuscular junction?
This is a synapse between a neuron and muscle cell.
What is a glandular Junction?
These are neurons that regulate or control the activities of secretory cells at the. Glandular junction.
