Questions Related to structure and function of neuron
-
True
-
False
In which region nerve impulses are transmitted and received?
-
Nodes of Ranvier
-
Dendrites
-
Axon
-
Synapse
The gap between two neurons across which impulses are conducted is known as a synapse. The presynaptic is the region of the axonic end of one neuron and the post synaptic is the dendritic end of the other neuron. It is a structure that permits a neuron to pass an electrical or chemical signal to another cell. It is important for neuronal function. The nerve impulses are transmitted and received with the help of this regions.
Thus, the correct answer is option D.
Which of the following statements explain the meaning of synapse.
-
Junction of two nerve cells.
-
Junction of two muscle cells.
-
Junction of two bone cells.
-
Junction of two sperm cells.
- Synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector)
- . A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.
What do will the microscope gap between a pair of adjacent neurons over which impulse passes?
-
Synapse
-
Axon
-
Dendrite
-
Cell body
-
None of these
- When a nerve impulse reaches the synapse at the end of a neuron, it cannot pass directly to the next one instead it triggers the neuron to release a chemical neurotransmitter. The neurotransmitter drifts across the gap between the two neurons.
So, the correct option is'Synapse'
Neurons have a unique property that makes them to communicate with other cells via
-
Nerve code
-
Glacial cells
-
Synapses
-
Schwinn cells
Synapse is a gap between two neurons which is filled with a neurotransmitter such as acetylcholine. It functions to transfer one neuronal signal to other by acting as a bridge. It allows the electrical signal to be converted into a chemical signal. So, the correct answer is option C.
The gap between two neurons is known as
-
Dendrite
-
Synapse
-
Axon
-
Impulse
Which of the following chemical is released in synapse?
-
Acetylcholine
-
Choline
-
Acetyl CoA
-
None of the above
Neurotransmitters are the chemicals that transmit the nerve impulse across the synapse. Acetylcholine is the neurotransmitter produced by cholinergic neuron. It is secreted by both pre- and post-ganglionic parasympathetic cholinergic neurons in synapse.
The word synapse was coined in
-
1897

The term synapse was first introduced in 1897 by neurophysiologist Charles Sherrington. The gap between two neurons across which impulses are conducted is known as a synapse. Synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell. It is important for neuronal function.
Thus, the correct answer is option A.
A place where a signal passes from one nerve cell to next is described as
-
Synaptic cleft
-
Synapsis
-
Synapse
-
Symport movement
The gap between two neurons across which impulses are conducted is known as a synapse. Synapse is a structure that permits a neuron to pass an electrical or chemical signal to another cell. It is important for neuronal function.
Thus, the correct answer is option C.
