When neuron is sufficiently stimulated this process starts the movement of ions across the axon membrane?
Depolavization
When the what reaches the end of the axon the neurotransmitter is released?
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
Do axon contain a nucleus?
No, the axon is a fiber that emerges from a neuron, while the nucleus is in the center of the neuron.
A synapse consist of?
A synapse is the connection between two neurons. It consists of the synaptic cleft (the physical gap between one neuron's axon and the other's dendrite). Neurotransmitters cross the gap from the axon to the dendrite and affect whether the next neuron fires.
Which ion causes neurotransmitter vesicles to fuse with the axon's membrane during the conduction of a nerve impulse from one neuron to the next?
calcium
What is a axon hillock?
An axon hillock is a special cell body that connects an axon to a neuron. It is the last place where propagated membrane potentials are transmitted to the axon.
During the absolute refractory period along an axon membrane of a neuron?
the neuron is unable to respond to a stimulus of any intensity
When the blank reaches the ends of the axon the neurotransmitter is released and diffuses to the muscle cell membrane?
Synaptic vesicle
What reaches the end of the axon when the neurotransmitter is released and diffuses to the muscle membrane to combine with receptors there?
nerve impulse
When neuron is sufficiently stimulated this process starts the movement of ions across the axon membrane?
Depolavization
In addition to the nucleus cytoplasm and cell membrane a single neuron possesses what?
Several dendrites and one axon
The first voltage-regulated gates encountered along the neuron membrane which initiate the formation of action potentials are located on the neuron near the?
axon hillock
What events occur in a neuron between the stimulus of a nerve and the stimulation of its target cell?
When a nerve is stimulated, its cell membrane is depolarised so that the inside of the cell becomes less negative. The potential is conducted along the axon to the axon terminal. At the dendrite it stimulates the release of a chemical transmitter, which diffuses across a synapse. The transmitter binds to receptor sites on the postsynaptic cell membrane to stimulate the generation of another impulse.
When the what reaches the end of the axon the neurotransmitter is released?
When the _____________reaches the ends of the axon the neurotransmitter is released and it diffuses to the muscle cell membrane to combine with receptors there?Sarcolemma
Do axon contain a nucleus?
No, the axon is a fiber that emerges from a neuron, while the nucleus is in the center of the neuron.
A synapse consist of?
A synapse is the connection between two neurons. It consists of the synaptic cleft (the physical gap between one neuron's axon and the other's dendrite). Neurotransmitters cross the gap from the axon to the dendrite and affect whether the next neuron fires.
Voltage regulated channels can be found where?
in the membrane that covers axonsThey are located in the axon hillock, nodes of Ranvier, and presynaptic terminal of the neuron.
