Final answer:
Nervous tissue is specialized for generating and transmitting electrical signals throughout the body, using neurons to propagate action potentials.
Step-by-step explanation:
The tissue that is specialized for generating electrical signals is nervous tissue. Nervous tissue is excitable and capable of sending and receiving electrochemical signals through components such as neurons and neuroglia. Neurons are specifically designed to propagate information via electrochemical impulses, called action potentials, which are critical for communication between different regions of the body.
