Verified step by step guidance

Step 1: Understand the function of each tissue type mentioned in the problem. Epithelial tissue covers and protects surfaces, muscle tissue is responsible for movement, connective tissue supports and connects other tissues, and nervous tissue is specialized for communication and control.

Step 2: Recall the primary role of nervous tissue. Nervous tissue is composed of neurons and supporting cells, and its main function is to transmit electrical signals throughout the body to coordinate activities.

Step 3: Identify the key phrase in the question: 'carries messages throughout the body to direct its activities.' This description matches the function of nervous tissue, as it is responsible for transmitting signals to regulate bodily functions.

Step 4: Eliminate the other options based on their functions. Epithelial tissue does not carry messages; it provides a protective barrier. Muscle tissue facilitates movement but does not transmit messages. Connective tissue provides structural support but does not direct activities.

Step 5: Conclude that the correct answer is nervous tissue, as it is the only tissue type specialized for carrying messages and directing activities in the body.
