Which tissue type is specialized for transmitting electrical impulses?

• A. Epithelial
• B. Connective
• C. Muscle
• D. Nervous

Answer: (D)

Nervous tissue is specialized for transmitting electrical impulses. Neurons have excitable membranes with ion channels that generate action potentials, allowing signals to be rapidly propagated along the cell’s axon and then transmitted across synapses to other neurons, muscles, or glands. Glial cells support this process and, when needed, form myelin to speed conduction. Epithelial tissue mainly protects and interfaces surfaces, connective tissue provides support and binding, and muscle tissue responds to signals to contract rather than primarily transmitting them.
