How do nerve impulses travel across the synapse?
By a chemical released by an axon.
When a neuron responds to a particular neurotransmitter by opening gated ion channels the neurotransmitter is serving as which part of the signal pathway?
The neurotransmitter functions as the ligand that binds to the receptor on the neuron's membrane, causing a conformational change that opens the ion channels. This allows ions to flow into or out of the neuron, resulting in a change in its membrane potential and ultimately transmitting the signal.
What effect does an action potential have on a vesicle?
It causes the vesicles (which are in the axon terminal) to move to the cell membrane at the end of the axon terminal, where they merge with the cell membrane, releasing their load of neurotransmitters into the synaptic cleft (gap), where they quickly diffuse to receptors in the post-synapticneuron's dendrites, initiating a graded potential which moves down the dendrites, along the soma,to the axon hillock where it can cause an action potential in that secondneuron.

How does synaptic transmission take place?
The synaptic transmission is where the communication between the terminal button and the dendrite occur. What happens is the impulse moves along the axon and release neurotransmitter from the end plate of the presynaptic neuron and are diffused across the synaptic cleft. This creates a depolarization of the dendrites of the postsynaptic neuron. When that happens the postsynaptic's sodium channels to open and start the action potential. Once the channels are open an enzyme called cholinesterase is released from postsynaptic membrane and it acts to destroy the neurotransmitters. When they are destroyed the sodium channels close and begins recovery.

When neurotransmeter released from nerv terminal?
After the neurotransmitter is released from the nerve terminal, it moves across the synapse. At that point, the neurotransmitter may bind with receptors.
What is the space between two neurons called?
The space between the ending of one neuron and the communication with the next neuron is called the synapse, or sometimes it is called the synaptic gap or synaptic cleft. But synapse is the common term.
Do neurons touch each other?
Not exactly; as an impulse moves from one neuron to another it crosses a small space between the neurons called a synapse. The neurons as said to 'not touch' because the cell MEMBRANES of the two neurons do NOT touch, nor merge, nor consequently is there any sharing of cytoplasm between the two neurons. The two neurons ARE, however, HELD TOGETHER at that synapse by small molecules called SYNAPTIC ADHESION MOLECULES, which protrude FROM each neuron into the synaptic cleft or gap and then stick to one another. In this sense, PARTS of neurons do 'touch' PARTS of other neurons, in a MECHANICAL or structural manner, but NOT in an electrical or signal sense. The neural SIGNAL passes through the synaptic cleft or gap via neurotransmitter chemicals which are released by one neuron, diffuse quickly through the gap, and then stimulate a signal in the receiving neuron.
What transfers a signal from the afferent nerve to the efferent nerve?
Neurotransmitters are released from the terminal bouton of the afferent nerve, cross the synaptic cleft, and bind with receptors on the efferent nerve. If enough neurotranmitter binds to reach the minimum potential, an action potential is created and the signal moves down the efferent nerve.
What is affected by parkinson's disease?
i was diagnosed of parkinson disease 5 years ago,i started azilect,then mirapex as the disease progressed in february last year,and i started on parkinson disease herbal medicine from ultimate life clinic,few months into the treatment i made a significant recovery,almost all my symptoms are gone,great improvement with my movement and balance,it been a year and life has been so good for me,reach them through there website at www .ultimatelifeclinic. com
