Explanation (300 Words)

Neurons are the fundamental units of the nervous system, responsible for transmitting electrical and chemical signals throughout the body. Their function is based on the movement of ions across the cell membrane, which generates electrical impulses known as action potentials.

When a neuron is at resting potential, the inside of the neuron is negatively charged compared to the outside. This state is maintained by the sodium-potassium pump, which actively transports sodium (Na⁺) out and potassium (K⁺) in, ensuring a polarized membrane.

When a stimulus is strong enough, depolarization occurs, where sodium channels open, allowing Na⁺ ions to rush in. This causes the inside of the neuron to become positively charged. The depolarization wave moves along the neuron, transmitting the signal.

After the peak of the action potential, repolarization restores the neuron’s negative internal charge as potassium ions (K⁺) exit the neuron. The refractory period follows, during which the neuron temporarily cannot fire another action potential until it returns to its resting state.

Neurons come in different types:

• Multipolar neurons have one axon and multiple dendrites, commonly found in the CNS.
• Bipolar neurons have one axon and one dendrite, often found in sensory organs like the eye.
• Unipolar neurons have a single branch extending from the cell body and are primarily sensory neurons that relay information to the CNS.

These processes ensure efficient communication within the nervous system, allowing for rapid responses to stimuli.
