The axon is a single process extending from the axon hillock, sometimes covered by a fatty layer called a myelin sheath that conducts nerve impulses away from the cell body of the neuron.
Distal tips of axons are telodendria, each of which terminates in a synaptic knob.
axon terminal
sacs are Synaptic vesicle.
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
in a nerve cell the axon terminals send signals or messages to other cells
Motor end plate of a cell is the dendritic portion that have cholinergic receptors to receive neurotransmitters in order to propagate an action potential.
Its the synaptic cleft found at the end of the axon terminal.
synaptic vesicles
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
Neurotransmitters are released when an action potential reaches an axon terminal (aka: end foot, synaptic knob, bouton), causing voltage-gated calcium ion gates to open, allowing calcium ions into the axon terminal, which causes vesicles containing the neurotransmitters to fuse to the cell membrane, which creates an opening to release the neurotransmitters into the synapse.
sacs are Synaptic vesicle.
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
Neurotransmitters are released in order to transmit the message from the axon terminal to the other neuron by having said synapse "jump" to the neighboring dendrite.
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel across the synapse. Once they reach the receiving cell, they create a new electrical signal.
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel acrross the synapse. Once they reach the receiving cell, they create a new electrical signal.
a neural impulse(electrical impulse) is released and it travels down the axon of a neuron to the axon terminals. At the axon terminal there are sacs called synaptic vesicles which contain chemicals called neurotransmitters. When the neural impulse reaches the terminal it causes the sacs to move closer to the membrane of the axon terminal and release the neurotransmitters inside. Then neurotransmitters travel across the synaptic gap and stimulate the dendrites of another neuron and the whole process starts again.
Impulses in the cell body (soma) of a neuron and move on along its axon, which conducts the impulse to a synapse at the end of the axon. There neurotransmitters are released into the synaptic cleft, so that the impulse can stop or go on to the next neuron or a gland/motor end plate, depending on the kind of neurotransmitter. Different types of neurotransmitters are: acetylcholine, adrenaline, noradrenaline, serotonine.
An axon terminal is the structure of a neuron (a single cell of the central or peripheral nervous system) at the end of it's axon that forms a synapse with another neuron. Generally, the axon terminal is the point at which a neuron passes information to the neurons with which it is connected.
