The document describes several types of human tissues. It notes that nervous tissue consists of neurons and neuroglial cells located in the brain, spinal cord, and peripheral nerves, which function to detect stimuli, respond, and transmit information. Skeletal muscle constitutes about 40% of body weight and is responsible for locomotion, facial expressions and other movements, under voluntary control by the nervous system. Smooth muscle is found in organs and blood vessels, functioning in movements like propelling urine and mixing food.
