Verified step by step guidance1
Understand the structure and function of nervous tissue: Nervous tissue is specialized for communication and consists of two main types of cells—neurons and neuroglia.
Define neurons: Neurons are the primary functional units of the nervous system. They are responsible for transmitting electrical signals and consist of three main parts—dendrites, a cell body, and an axon.
Define neuroglia: Neuroglia, also known as glial cells, provide support, protection, and nourishment to neurons. They do not transmit electrical signals but play essential roles in maintaining the health and functionality of the nervous system.
Eliminate incorrect options: Adipocytes are fat cells and are not part of nervous tissue. Collagen fibers and elastic fibers are components of connective tissue, not nervous tissue.
Select the correct answer: Based on the definitions and eliminations, the main components of nervous tissue are neurons and neuroglia.
