Question

The gap between two neurons are known as
A) Dendrite
B) Synapse
C) Axon
D) Impulse

Answer 1

Hint: The neuron is the central working component of the brain. The brain is as it is because of the anatomical and functional properties of the interlinked neurons.

Complete Answer:
- The human nervous system consists of the central nervous system and peripheral nervous system. The central system includes Brain and Spinal cord. The peripheral system includes neurons.
- There are three different types of neurons as sensory, motor and interneurons. But the function of every neuron is the same. They collect the information, integrate the collected pieces of information, and then communicate the information to other target cells. Each neuron has the ability to generate electrical signals known as action potentials which helps neuron in transmitting information to other cells.
- Every neuron has a cell body, an axon, and dendrites. The nucleus and cytoplasm form the cell body. The short branches from the cell body are dendrites and the axon is more longer than dendrites. Each neuron is interconnected with each other.
- Neurons can communicate with one another at a junction called synapses. At the synapse, the information is carried from the first neuron to the last neuron. Two neurons are never physically connected with each other.
- Most synapses communicate with each other chemically. At a chemical synapse, the neuron releases neurotransmitters. Sometimes, few synapses are electrical too, in which the ions will flow directly between the cells.

The correct answer is option B, the synapse.

Note: The brain of mammals comprises between 100 million and 100 billion neurons, depending on the organism. Glia is also important to the operation of the nervous system, but they mainly act by helping the neurons.
