The correct option for a man type of muscle tissue is option 4: Cardiac.
The correct answer is option 4: Cardiac. Cardiac muscle tissue is a type of muscle tissue found in the walls of the heart. It is responsible for the heart's pumping action and helps to circulate blood throughout the body.
To choose the correct option, we need to understand the characteristics of different types of muscle tissues. Muscle tissues can be broadly categorized into three types:
1. Skeletal muscle: Skeletal muscles are attached to bones and are responsible for voluntary movements of the body. These muscles are long, cylindrical, and have multiple nuclei. Examples include the muscles of arms, legs, and abdomen.
2. Smooth muscle: Smooth muscles are found in the walls of organs such as the digestive system, blood vessels, and urinary bladder. They are responsible for involuntary movements, like the contraction and relaxation of the digestive tract. Smooth muscles are non-striated, spindle-shaped, and have a single central nucleus.
3. Cardiac muscle: Cardiac muscle tissue is unique to the heart. It is responsible for the heart's pumping action and contractions. Cardiac muscles are striated, like skeletal muscle, but are involuntary, like smooth muscle. They have branched fibers with a nucleus present in the center of each fiber.
From the given options, blood vessels, skin, and spongy bone are not types of muscle tissues. Blood vessels are a part of the circulatory system, skin is a protective covering, and spongy bone is a type of bone tissue. Therefore, the correct answer is cardiac muscle, which is a type of muscle tissue found in the heart.
