Usually see flat cells, frequently renewed, with surface specializations. Connective tissues support and bind other tissues together. Connective tissues can be either loose, like the aleolar connective tissue underneath the dermis of your skin, or fibrous, densely packed as in tendons and ligaments. Muscle tissue allows movement. There is smooth muscle in the gut, cardiac muscle in the heart, and striated muscle under voluntary control in your limbs.
Muscles work by contraction via the action of actin and myosin.
Nervous tissue , made of neurons, is for communication. CP Hickman et al., Biology of Animals, 7th ed.
