Question

Axosomatic synapse is
A. Synapse of axon
B. The synapse of the cell body
C. Postsynaptic ending at the dendrite
D. None of the above

Answer 1

Hint: In the nervous system, a synapse is a structure that permits a neuron or a nerve cell to pass an electrical or chemical signal to another neuron or the target effector cell. The target effector cell is called the soma of a neuron.

Complete answer:
Axosomatic synapses occur between the axon of one neuron and the cell body of another. This type of synapse is called cell body synapse. A human brain is a complex network that contains around 90 billion neurons. These neurons communicate with one another through connections called synapses.
The dendrites and axons are the specialized projections present in the neurons that bring information to and from the cell body from the cell body respectively.
The neurotransmitter (such as acetylcholine) travels from the synaptic gap to the dendrites of the neuron on the other side in the form of impulse. Synapses are generally directional in function, such that their activity at the foot of the sending neuron affects through the head of the receiving neurons.
Three important parts of a synapse are:
Presynaptic neuron: which consists of neurotransmitters, mitochondria, and other cell organelles.
Postsynaptic neuron: is one that contains receptor sites for neurotransmitters.
Synaptic cleft: is an empty space present between the presynaptic and postsynaptic endings.
In most neurons, the synapses occur between axons also. The postsynaptic membrane is usually present on the cell body or dendrites.

So, the correct answer is option b, 'the Synapse of the cell body’.

Note:.
On this basis, synapses are divided into the following three categories:
Axosomatic Synapses: are one that are present in between the axon of one neuron and the body of another.
Axodendritic Synapses: are found between the axon of one neuron and the dendrites of the other.
Axoaxonic Synapses: are those that are present between the axons of two neurons.
