Smooth muscle
The function of the Smooth muscle are the muscle we do not consciously control eg those that are found in the walls of blood and lymphatic vessels, in respiratory, digestive and genito-urinary systems. These muscles work automatically weather we want them to or not.
The structure of the smooth muscle is they have spindle shaped cells with no distant cell membrane and only one nucleus, bundles of the fibre we see with the naked eye.

Skeletal muscle the function is these are the muscle which we consciously control eg or arms, legs. If we want to walk we do so. The structure is the skeletal musclehas cells which make up fibres, each fibre has several nuceli (multi-nucleated cells) and is surrounded by a sheat (sarcolemma). The

The composition of the long bone itself mainly of collagen fibers and an inorganic bone mineral in form of small crystals, In vivo bone (living bone in the bone the body) contains 10% and 20% of water of its dry mass, approximately 60-70% is bone mineral.

Structure of the long bone are those that they are longer than they are wide. They are one of five types of bones, long short flat irregular and seasmoid. Long bones especially the femur and tibia are subjected to most of the load during daily activities and they are crucial for skeletal mobility. The long bone is that it allows movement , particularly in the limbs eg the femur (thigh bone) tibia and fibula (lower leg bones) humerus (upper arm bone), the radius and the ulna (lower arm). Metacarpals (hand bones) metersals (foot bone) and phalanges (finger and toe bone)

Functions of the skeleton
The skeleton is the framework of the body; it supports the softer tissue and provides point of attachment for most skeletal muscles. The skeleton provides mechanical protection for many of the body’s internal organs, redusing risk of injury to them. Skeletal bones are attached to the muscle contract they cause bone to move, packed with over 200 bones, skeletons protect, shape support and move our bodies as well as producing red blood cells in the bone

The coronal structure connects parietal bones. The labroid suture unites the parietal with the occipital.
Ball and socket joint as one in which the rounded surface of a bone fits into and moves within a cup-shaped depression, examples of this type of synovial joint are hip and shoulder joints. The ball-and-socket joint allows freedom of movement up, down, right left and in full 360-degree rotation.

Gliding joints allows two or more flat or slightly rounded bones to move easily together without friction or grinding. The function of a gliding joint is to allow motions such as smooth sliding of bone past bone, bending, stretching and circular motion. Examples of gliding joints include the forearm to wrist arm and lower leg to ankle joint.

Pivot joint is a synovial joint designed with one end fitting like a cylinder like a ring. Pivot joints at the base of the skull and allows the head to rotate. Other pivot points allow the rotation of the
