  1. Visceral muscle is found inside of organs like the stomach , intestines, and blood vessels. The weakest of all muscle tissues, visceral muscle makes organs contract to move substances through the organ. Because visceral muscle is controlled by the unconscious part of the brain. It is known as involuntary muscle—it cannot be directly controlled by the conscious mind. Skeletal muscle is a type of striated muscle, attached to the skeleton Did you know you have more than 600 muscles in your body? They do everything from pumping blood throughout your body to helping you lift your heavy backpack. You control some of your muscles, while others — like your heart — do their jobs without you thinking about them at all. Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle. . Muscles are grouped together in pairs on your skeleton. muscle

  2. invertebrates Invertebrates are animals with no back bone.

  3. What are muscles !!! • Muscles are made of fibres. Each fibre is made up of long thin cells which are packed in bundles. The fibres have two kinds of protein, myosin and actin. Each bundle is wrapped in a thin skin called perimysium. Many different types of joints exist in the human body, but the kind which allows the greatest range of motion is the ball and socket joint. These joints are present where one bone ends with a spherical knob that lies in a circular depression in the other bone. This arrangement theoretically allows for 360 degrees of rotation — in other words, a full circle. Each shoulder has a ball and socket joint where the upper arm meets the shoulder blade. The hips also have this type of joint on either side, where the femurmeets the pelvic bone
