Gap between nerve cells?
SynapseSynapse.The gap between the axon of one nerve cell and the dendrite of another nerve cell is called the synapse. Synapses are the space into which neurotransmitters are released from the axon to act on the dendrite, and thus transmit a signal between neurons.If the axon and the dendrite are from the same cell (i.e., the neuron is making a synapse with itself), this gap is called an autapse ("auto-synapse").Synapsea synapseA synapse or synaptic gap.Its a cool name.Neat huh?synapseSynapseSynapse
Why is the synapse not a structural feature of a neuron?
Because it is a small gap between the axon of one neuron and the receiving dendrite of another neuron.
What is the space between a dendrite and an axon called?
The space between neuronal celll bodies is the extracellular space, which is filled with extracellular fluid. The space between neurons in contact with one another via a synapse is called a synaptic cleft.
How do impulses travel throughout the nervous system?
An impulse travels from one nerve to another by release & subsequent diffusion of chemicals called neurotransmitters across a very small gap between neurons, called a synapse.How neurotransmitters are released: As an impulse reaches an end of a neuron (the axon terminal), the impulse opens ion pores in that axon terminal which allows Calcium ions to enter, which cause the movement of small membrane bounded packets of neurotransmitter chemicals, called vesicles (like tiny water balloons), to move to the cell membrane, where the vesicles fuse into the cell membrane, thus releasing the contents, the neurotransmitters, into the small space (the synaptic cleft) between the axon terminal and the dendrite of the post-synaptic neuron (the neuron the impulse is traveling to).What neurotransmitters do when they reach the post-synaptic neuron: The post-synaptic neuron has many receptor structures each of which are like a combination of a "well", and an open-and-closeable tunnel or pore. The "well" (or hole with a bottom surface) is a RECEPTOR for the neurotransmitter chemical, in that the neurotransmitter FITS into that well like a key into a lock. And when a neurotransmitter diffuses to and enters that well, it affects the shape of the companion tunnel (ION PORE), such that the ion pore OPENS, thus allowing Sodium ions to enter the post-synaptic neuron (normally at a dendrite, the manifold tiny input structures for a neuron).A previous answer slightly improved: Nerve impulse travelingThe impulse is like an electrical current which 'flows' along the nerves cells, their inputs ('branches' called dendrites), their outputs (axons), and the junctions between nerves; but it is not so simple as a regular electrical wire, because a complex biochemical process is also involved. This process is responsible for the initial creation of the electrical current, to its re-creation some additional times along its passing (- otherwise it would have died out because of the long lengths such an impulse travels), and to its re-creation in any 'new' nerve cell it reaches.
Does Dendrites generate and send signals to other cells?
Dendrites are a characteristic of neurons. Neurons are comprised of a soma, or cell body, dendrites, and axons. The soma is located in the center of the neuron and is the location of the nucleus, mitochondria, and other organelles. The dendrites are attached to the cell body; there can be multiple dendrites, up to thousands, or there can be just one. The final structure is what is called an axon. A neuron can only have one axon, which can branch off. At the end of the axon are end terminals, or terminal buttons. These are what "connect" to other neurons (by connecting to their dendrites). The connection goes: terminal button, dendrite, soma, axon, terminal button, dendrite, soma, etc. However, the terminal button and dendrite never actually come in contact; they are separated by a very small gap known as the synaptic cleft.
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.

What is the small space between the end of one axon and the next neuron?
The Synapse is the area between an axon and a dendrite
Why is the synapse not a structural feature of a neuron?
Because it is a small gap between the axon of one neuron and the receiving dendrite of another neuron.
What is the space between a dendrite and an axon called?
The space between neuronal celll bodies is the extracellular space, which is filled with extracellular fluid. The space between neurons in contact with one another via a synapse is called a synaptic cleft.
The actual gap between an axon ending and the muscle cell is called what?
Neuromuscular junction.
Does ionic current exist in chemical synapse?
not within the synaptic CLEFT (gap) itself, across which neurotransmitters diffuse, but yes, in the axon & axon terminal leading up to the synapse, and in the dendrite coming from the synapse.
What is the structure that connects two neurons?
The synapse. It's comprised of 3 parts: an end of the pre-synaptic neuron (called an axon terminal, or axon button), the beginning of the post-synaptic neuron (usually a dendrite, or often a dendritic spine), and the gap in between them (called the synaptic cleft).The synapse is held in place by small molecules called synaptic adhesion molecules, which protrude from each of the axon terminal and the dendrite, and stick together along parts of their lengths, like the two end joints of two fingers, one from each hand, laying against one another and glued together there.
What are the Chemicals that cross the synaptic gap and bind to receptors on another neuron called?
Synapse is a narrow gap containing communicating junction between two neurons where an axon terminal comes near contact with dendrite terminal of next neuron. A narrow fluid filled space, called synaptic cleft, occurs between the two.As the impulse reaches the presynaptic knob, it stimulates release of neurotransmitter into the cleft.
Gap between axon terminal and muscle cell?
The gap between the axon terminal and muscle cell is called the synaptic cleft. It is defined as the small gap, measured in nanometers, between an axon terminal and any of the cell membranes in the immediate vicinity.
What does the axon bulb do?
It starts the transmission of a neural signal from one neuron to another.An axon ends in an axon terminal, which ends in a small rounded tip called the axon bulb. Each terminal lies very close to either a dendrite or a cell body of another neuron, and the combination of the end of the first neuron, the beginning of the next, and the space between them is known as a synapse; when a neural impulse reaches the axon bulb, it is stimulated to release chemical messengers called neurotransmitters into the synaptic cleft (gap), which diffuse over to the second neuron, conveying the signal to the second neuron.
What is the gap called that separates the myelin sheaths?
The gap that separates the mylene sheaths is the axon.
