1. The three types of muscles in the muscular system are, smooth muscle, cardiac muscle, and skeletal muscle, and their functions are to start the movement of food, heart movement, and control the body's contractions.
2. The sliding filament which belongs to the muscle contraction, states that when signal, the acting filaments within each slide toward another.
3. Exercise can change muscle strength by stressing the muscle.It can also change muscle function by squeezing, exerting pressure on the space inside the tube it surrounds.
4. Muscle strength is determined by the thickness of the fibers and on how many of them contract at one time.
5. Paralysis of smooth muscles are life threatening, because the digestive system is a part of the smooth muscles.

Section 34.1
1. The epidermis is the outer most layer of the skin, and is made up of two parts- an exterior and interior portion. Meanwhile the dermis is the thickness of the dermis varies in different parts of the body, depending on the function of that part.
2. The integumentary system is composed of layers from the four types of body tissues epithelial, connective muscle, and nervous system. Its functions include, maintenance of homeostasis by regulating your internal body temperature. Sweat glands produce sweat in response to body temperature.
3. The skin interrelates with other organ systems to maintain a constant body temperature by, regulating the bodies internal body temperature.
4. The skin responds to external stimuli by cold and fright. Nervous tissue helps us detect external stimuli, such as pain or pressure.
5. A third-degree burn affects the body as a whole because, with this type of burn, the skin function is lost, and skin grafts may be required to replace lost skin.

Chapter 34 Section 34.2 Skin:The Body's Protection Bones: The Body's Support pg. 904 ?'s 1-5
1. The appendicular skeleton includes the bones of the arms and legs and structures associated with them, such as the shoulder and hip bones, wrists, ankles, fingers, and toes. While the axial skeleton includes only the skull and the bones that support it, such as the vertebral column, the ribs, and the sternum.
2. The four main kinds of joints of movable joints are the joints, which are found where two or more bones meet; example: the skull. Ligament, which is a tough band of connective tissue that attaches one bone to another; example: knee. The bursae, located on the outside of the joints; example: the shoulder. And lastly the Tendons, which are thick bands of connective tissue, attaches muscles to bones; examples: wrist, ankle, and knee.
3. A compact bone is different from the spongy bone because the compact bone is the surrounding of every bone in a layer of hard bone and it also surrounds less dense bone than the spongy bone.
4. The functions of the skeletal system are to provide the framework for the body.
5. It would be impossible for bones to grow from within because, in normal bone formation and bone resorption are closely coupled processes involved in the normal remodeling of the bone.
