Tissues of the Nervous System

The two main types of cells in nervous tissue are neurons, which transmit signals, and neuroglia, which support and protect neurons. Therefore, the correct answer is neurons and neuroglia.

The primary function of neurons is to carry messages throughout the body. They transmit signals between different parts of the body, enabling communication and coordination of bodily functions.

The axon is the part of the neuron that transmits electrical impulses away from the cell body, facilitating communication through an electrochemical process. It plays a crucial role in sending signals to other neurons.

When neurons die, they are typically not replaced, which means the loss of these cells can lead to permanent deficits in function. Unlike some other cell types, neurons have limited regenerative capacity.

Sensory (Afferent) Neurons are responsible for transmitting information from sensory receptors to the central nervous system (CNS), making them the correct choice for this question.

The main characteristic of white matter is that it appears white due to the myelin sheath, which insulates axons and enhances the speed of electrical signals in the nervous system.

Neuroglia, or glial cells, play a crucial role in supporting and protecting neurons. They provide structural support, maintain homeostasis, and assist in the repair of nervous tissue, unlike neurons which transmit electrical signals.

Glial cells support and protect neurons but do not transmit nerve impulses. That function is specific to neurons themselves, making 'To transmit nerve impulses' the correct choice as it is NOT a function of glial cells.

Gray matter is primarily composed of cell bodies, which contain the nucleus and organelles of neurons. This distinguishes it from white matter, which is mainly made up of myelinated axons.

Interneurons are the type of neurons that connect sensory neurons, which receive information, to motor neurons, which execute responses. They play a crucial role in processing and relaying signals within the nervous system.
