Because it is a small gap between the axon of one neuron and the receiving dendrite of another neuron.
Yes, a synapse is the space (a VERY SMALL one!) between the axon of one neuron and the dendrites of the next neuron.
A synapse is a small gap at the end of a neuron that allows information to pass from one neuron to the next.
dendrite
Dendrite
A dendrite (or often a small protrusion from it called a dendritic spine) is the structure of a neuron that is usually the input to the neuron. A synapse is what makes the input to a neuron, via chemical messengers called neurotransmitters. And inputs to a neuron cansometimes be made to the soma (body) of a neuron, or even to the axon. But the dendrites are the "normal" input structures.
The Synapse is the area between an axon and a dendrite
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.
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.
It is the junction between terminal part of one axon and the dendrite of the adjacent neuron .Synapse helps in the transmission of impulses from one neuron to another neuron.
The end of one neuron, the presynaptic button, sends messages to other cells by releasing neurotransmitters (chemical messengers) into the synaptic cleft (a small space between two neurons). The other cell, whether it be a neuron, a muscle, a sweat gland, etc., will receive this message at the post synaptic membrane of its cell, and will respond accordingly.
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.
