Final answer:
Nervous tissue is composed of two types of specialized cells: electrically active neurons that transmit information and supportive glial cells that maintain the environment for neurons to function efficiently.
Step-by-step explanation:
Nervous tissue contains specialized cells known as neurons and glial cells. Neurons are the primary communicators in the nervous system, responsible for transmitting information via electrical signals, often referred to as action potentials. These action potentials facilitate the release of chemical signals to target cells. Complementing the function of neurons are glial cells, which provide support, insulation, and nutrients, maintaining a healthy environment for neuronal function. Glial cells also assist in cleaning up debris, modulating nerve impulse transmission, and at times, participating in signal communication.
The nervous tissue, essential for the nervous system's operation, is found throughout the central nervous system (CNS) and peripheral nervous system (PNS). It plays a critical role in reacting to stimuli and conducting impulses to various body parts, eliciting responses for myriad functions.
