Verified step by step guidance
1
Step 1: Begin by identifying the primary function of muscle tissue. Muscle tissue is specialized for contraction and movement, which is essential for locomotion, posture, and various bodily functions such as pumping blood (cardiac muscle) and moving food through the digestive tract (smooth muscle).
Step 2: Evaluate the other options provided in the question. Muscle tissue is not primarily responsible for transmitting electrical impulses; that is the role of nervous tissue, which consists of neurons and glial cells.
Step 3: Consider the option about forming the outer protective layer of the body. This is the role of epithelial tissue, which forms the skin and lines internal organs, providing protection and acting as a barrier.
Step 4: Analyze the option about secreting hormones. Hormone secretion is primarily the function of endocrine glands, which are composed of specialized epithelial cells, not muscle tissue.
Step 5: Conclude that the correct answer is the first option: 'Muscle tissue is specialized for contraction and movement,' as this aligns with the primary function of muscle tissue in the body.
