To know the histological structure and ultrastructure of the three main types of muscle and how their structure relates to function.

There are 3 types of muscle, 2 striated (skeletal, cardiac) and 1 non-striated (smooth).
Skeletal muscle connects with bones, cartilages, ligaments, and skin. The connection can be either directly, or through fibrous structures (tendons or aponeuroses). Where muscle is attached to bone or cartilage, the fibers end in blunt extremities upon the periosteum or perichondrium, and do not come into direct relation with the osseous or cartilaginous tissue.
The contractile units (sarcomeres) are organised in series within the muscle fibre, giving the muscle a "striated" appearance. In series each shorten a small distance (microns) that add together to shorten the whole muscle fibre (centimetres).

The gastrointestinal tract and uterus have muscular walls formed by smooth muscle, called smooth because it does not have a striated appearance. There is also varying amounts of smooth muscle in many other tissues and organs, for example around the walls of blood vessels.
