NEET PG DENTAL EXAM

Detailed explanation-1: -In addition to the cell body, or soma, which is much like that of other cells, neurons have specialized thin branches know as dendrites and axons. Neurons receive chemical input from other neurons through dendrites and communicate information to other cells through axons. Neurons also are “excitable” cells.

Detailed explanation-2: -Neurons talk to each other using special chemicals called neurotransmitters. Neurotransmitters are like chemical words, sending “messages” from one neuron to another. There are many different sorts of neurotransmitters: some stimulate neurons, making them more active; others inhibit them, making them less active.

Detailed explanation-3: -The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

Detailed explanation-4: -Two mechanisms have evolved to transmit nerve signals. First, within cells, electrical signals are conveyed along the cell membrane. Second, for communication between cells, the electrical signals generally are converted into chemical signals conveyed by small messenger molecules called neurotransmitters.
