What type of tissue is responsible for transmitting impulses throughout the body?

Nervous tissue is the correct choice because it is specifically designed for the transmission of impulses throughout the body. This tissue is composed mainly of neurons and glial cells. Neurons are specialized cells that generate and transmit electrical signals, allowing for communication between different parts of the body, including the brain, spinal cord, and peripheral nerves. This function is essential for coordinating bodily functions, reflexes, and responses to stimuli.

Epithelial tissue serves primarily as a protective layer covering body surfaces and cavities, and it plays a role in absorption and secretion. While important for various bodily functions, it does not transmit impulses.

Muscular tissue is responsible for movement in the body, contracting to produce motion, but it is not involved in the transmission of impulses.

Connective tissue serves to support and bind other tissues and organs together, providing structural and functional support, but it does not transmit electrical impulses.

Thus, nervous tissue uniquely fulfills the role of impulse transmission, making it the correct answer.
