Question

Junction between the axon of the one neuron and the dendrite of the next is called as
A. Joint
B. Synapse
C. Constant bridge
D. Junction point

Answer 1

Hint: A neuron, also known as a nerve cell, is an electrically excitable cell that communicates with other cells through synapses, which are specialised connections between cells. Except for sponges and placozoa, it is the major component of nerve tissue in all animals. Nerve cells do not exist in plants or fungi. A neuron's cell body (soma), dendrites, and a single axon make up a typical neuron.

Complete explanation:
Option A: The region of the body where two or more bones unite to facilitate movement is called a joint.
So, option A is incorrect.
Option B: A synapse is a connection between the synaptic knob of one neuron's axon and the dendron of the next neuron.
So, option B is correct.
Option C: Constraints, limits, or biases on the course or outcome of adaptive evolution are known as evolutionary constraints. The word is used to describe elements that restrict or channel natural selection's activity.
So, option C is incorrect.
Option D: Cell junctions are multiprotein complexes that allow contact or adhesion between nearby cells or between a cell and the extracellular matrix in animals.
So, option D is incorrect.

Therefore, Option B is the correct answer.

Note:
The nervous system's building blocks are neuronal cells. They send and receive messages to many regions of the body. This may be done both physically and electrically. Neurons come in a variety of shapes and sizes, all of which aid in the transfer of information. Sensory neurons provide information to the brain from sensory receptor cells located throughout the body. The motor neurons, on the other hand, send information from the brain to the muscles.
