Structure of neuron:-

A typical neuron consists of a cell body (soma), dendrites, and a single axon. The soma is usually compact. Most neurons receive signals via the dendrites and soma and send out signals down the axon. At the majority of synapses, signals cross from the axon of one neuron to a dendrite of another.

Structure of brain:-

The brain has three main parts: the cerebrum, cerebellum and brainstem.Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.Cerebellum: is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

Functions of brain:-

The brain controls our thoughts, memory and speech, movement of the arms and legs, and the function of many organs within our body. The central nervous system (CNS) is composed of the brain and spinal cord.
