Identify the three types of muscle tissue. Compare and contrast the functions of each muscle tissue type. Muscle tissue is characterized by properties that allow movement. Muscle cells are excitable; they respond to a stimulus. They are contractile, meaning they can shorten and generate a pulling force.
There are three major types of muscle tissues in the human body: skeletal, smooth, and cardiac muscle tissues. Figure \(\PageIndex{2}\) shows how the three types of muscle tissues appear under a microscope.
Muscle tissue is subdivided into three broad categories: skeletal muscle, cardiac muscle, and smooth muscle. The three types of muscle can be distinguished by both their locations and their microscopic features.
Unlike other tissue, skeletal muscle cells contain myofibrils – these are shaped like long cylinders and extend along the full length of the muscle fibre/cell. Each myofibril consists of two types of protein filaments called thick filaments and thin filaments.
Virtual microscope slides of muscle tissue - skeletal muscle, cardiac muscle (including Purkinje fibers), and smooth muscle.
4 lis 2023 · Skeletal muscle tissue is made up of a collection of muscle fibers wrapped in connective tissue sheaths. There are three types of connective tissue sheaths named for their location. Endomysium surrounds individual muscle fibers.
Skeletal muscle is found attached to bones. It consists of long multinucleate fibers. The fibers run the entire length of the muscle they come from and so are usually too long to have their ends visible when viewed under the microscope.
