Unformatted text preview: 3 types of muscle tissues Found only in heart (cell membrane of muscle cell) (cytoplasm of muscle cell) (able to generate tension **) Striated = apparent, stripped under the microscope Smooth = when looking at cytoplasm, it is homogenous Muscle October 9, 2010 3:59 PM Muscle Page 1 3 types of muscle tissues Found only in heart Walls of viscera organs (cell membrane of muscle cell) (cytoplasm of muscle cell) (able to generate tension **) Striated = apparent, stripped under the microscope Smooth = when looking at cytoplasm, it is homogenous Muscle Page 2 (i.e. bicep) <--As skeletal muscle is an organ, it has CT covering over it. It is closing individual organ & connects to other structure. <--subdivisions of epimysium (CT of muscle = epimysium) Perimysium is subdivided from neighboring m by CT tissue layer known as "perimysium" Each muscle fascicles is very large Hence, muscle fibre Muscle Page 3 <--proximal end of humorous (CT that surround the organ) Muscles are divided into fasicles (2nd level of CT) (individual cell of skeletal muscle surrounded by endomysium) <--bundles of protein fibers Skeletal muscle cells are individual cells NOT physically connected with each other. Therefore, CT are very important to pull cells closer together to pass tensions generated from one to another for movement. Layers of CT turn into tendon. Muscle Page 4 Tendon attached muscle to bone. Aponeuroses attaches a muscle & looks like sheet of paper. Each individual muscle cell is contacted by an axon Muscle Page 5 (these fuse again and again..to end cylindrical shape) (during development) (Few myoblasts will remain as "Satellite cell". These will be associated with mature muscle fibres. They will retain ability to derive (undergo mitosis). When skeletal muscle is injured, it is replaced with scar!!) Therefore, minimum ability - Muscle Page 6 <-- Characteristic of skeletal & cardiac muscle** Cylinders of membrane that runs deeply into the hole Myofibrils --> bundles of filamentous proteins Myofilaments --> filamentous protein ER responsible for production of different molecules. Terminal cisterna <-> t-tubule <-> terminal cisterna Muscle Page 7 (cell membrane)...
