The presence of which cells characterizes nervous tissue?

Nervous tissue is uniquely characterized by the presence of neurons and glial cells. Neurons are the fundamental functional units of the nervous system; they are responsible for transmitting nerve impulses, processing information, and facilitating communication within the nervous system. Glial cells, also known as neuroglia, support neurons by providing structural support, insulating nerve fibers, facilitating nutrient transport, and maintaining homeostasis in the neural environment. Together, these two cell types form the basis of the nervous tissue, enabling it to perform its vital functions in the body.

Other cell types listed in the choices do not pertain to nervous tissue. Adipocytes are fat cells that store energy in the form of fat, primarily associated with adipose tissue. Osteocytes are mature bone cells found in bone tissue, and chondrocytes are cartilage cells that contribute to the structure of cartilage. Therefore, B is the choice that accurately represents the cells that characterize nervous tissue.
