Histology Of Nervous System! Trivia Questions Quiz

The central nervous system (CNS) is the body's control center, responsible for processing information and coordinating responses. It consists of the brain, which is the main processing unit, and the spinal cord, which acts as a conduit for transmitting signals between the brain and the rest of the body.

Neurons are highly specialized cells that form the basis of the nervous system. They are responsible for transmitting information throughout the body via electrical and chemical signals. Each neuron consists of a cell body, dendrites, and an axon, which work together to receive, process, and transmit nerve impulses.

Neuroglial cells are nonexcitable cells of neural tissue, meaning they cannot generate or transmit nerve impulses. On the other hand, neurons are excitable cells that are specialized to generate and transmit electrical signals. This functional difference is important because neurons are responsible for transmitting information throughout the nervous system, while neuroglial cells have supportive roles such as providing structural support, insulation, and nourishment to neurons.

The correct answer is "The epidemal cells." Epidemal cells are a sub-type of neuroglial cells that line the central canal. These cells are responsible for providing support and protection to the central nervous system.

Dendrites are the receptive regions of a neuron, meaning they receive signals from other neurons. They have a diffusing branching structure that provides a large surface area for receiving these signals. This allows the dendrites to effectively collect and transmit information to the cell body of the neuron.
