What is the difference between synaptic and nerve impulse transmission?
Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
What is accomplished by synaptic transmission?
Synaptic transmission, also called neurotransmission, refers to the process wherein neurotransmitters are released by a neuron to activate the receptors of another neuron. Communication between two nerve cells is accomplished by synaptic transmission.
What is one dietary factor that affects synaptic transmission of nerve impulses?
vitamen b12
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of nerve cells.
What part of the neuron that facilitates synaptic transmission of a signals is called?
the part that facilitates the the transmission of signals is collectively known as the axon but more peculiarly known as the nerve endings.
When a nerve impulse reaches the end of the axon the tiny sacs that store the neurotransmitters move to the surface and release the neurotranmistters These tiny sacs that store the neurotransmitters?
are called synaptic vesicles. They contain specific neurotransmitters that are released into the synaptic cleft when the nerve impulse reaches the end of the axon. The neurotransmitters then bind to receptors on the neighboring neuron, continuing the signal transmission.
Where do nerve impulses leave the neuron?
Nerve impulses are transmitted down the axon and leave the neuron via the terminal bouton at the synaptic interface, releasing neurotransmitters into the synaptic cleft to affect the post-synaptic cell..
What is the effect of the myelin sheath on synaptic transmission?
Myalin sheath gives insulation to the neurons. They also hasten the nerve conduction by saltatory conduction.
What is the normal sequence of events that occur during synaptic transmission at a motor end plate?
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.
What is a synaptic gap?
This is the junction between two neurons. At the one end you have the pre-synaptic membrane - the terminal end of the previous neuron, the pre-synaptic neuron - and on the other side you have the post-synaptic membrane, part of the post-synaptic neuron. Action potentials typically cross the cleft by the use of neurotransmitters. Examples include ACh (Acetyl Choline), often used in the synaptic clefts of parasympathetic neurons.
Neurotransmitters are released from what end of an axon?
synaptic vesicles
Is a flow chart appropriate to illustrate the process of synaptic transmission?
no, because a diagram should be used to represent the processFlow chart to illustrate the events occurrung in an axon of a neuron with the arrival of a nerve impulse
