MUSCLES, BONES, And Joints. TYPES OF MUSCLE. Smooth Involuntary Cardiac Involuntary Voluntary Skeletal Voluntary Attached to skeleton. Types of Muscle Continued.
CARDIAC MUSCLE:The cardiac muscles is the muscle of the heart itself. The cardiac muscle is the tissue that makes up the wall of the heart called the mydocardium. Also like the skeletal muscles, the cardiac muscle is striated and contracts through the sliding filament method. However it is different from other types of muscles because it forms branching fibers. Unlike the skeletal muscles, the cardiac muscle is attached together instead of being attach to a bone.SKELETAL MUSCLE:The skeletal muscle makes up about 40 % of an adults body weight. It has stripe-like markings, or striations. The skeletal muscles is composed of long muscle fibers. Each of these muscles fiber is a cell which contains several nuclei. The nervous system controls the contraction of the muscle. Many of the skeletal muscle contractions are automatic. However we still can control the action of the skeletal muscle. And it is because of this reason that the skeletal muscle is also called voluntary muscle.SMOOTH MUSCLE:Much of our internal organs is made up of smooth muscles. They are found in the urinary bladder, gallbladder, arteries, and veins. Also the digestive tract is made up of smooth muscle as well. The smooth muscles are controlled by the nervous system and hormones. We cannot consciously control the smooth muscle that is why they are often called involuntary Muscle Functions
Latissimus dorsi (lats)
Rectus abdominus (abs)
you wouldn’t have control like you do now.
Endoskeleton:Human have an endoskeleton, meaning that they are located inside the body. It consists of about 200 bones. The number of bones varies, because some bones fuse at different periods of time. Most bones are hollow with marrow cells inside. Ligaments connect bones to bones, and tendons connect bones to bones.Axial SkeletonConsists of the skull, backbone or "vertebrae," ribs and breast bone, or "sternum".Appendicular SkeletonBones of arms and legs or "appendage", and girdler, which attach them to the rest of the body.

The condylar joint is a joint allowing primary movement in one plane, with small amounts of movement in another plane (rotation). It is found at the knee joint.
The ellipsoid joint allows movement in two planes and is biaxial. Examples of this joint can be found at the at the wrist.
The ball-and-socket joint allows movement in three planes and is the most mobile of the joints. The hip and shoulder joints are example of ball-and-socket joints.
