- 2. A muscle is a tissue that has the ability to contract Types of Muscle tissue: Skeletal Cardiac Smooth muscle
- 3. Skeletal and cardiac muscle are striated However, the term striated, usually refers to skeletal muscle Smooth muscle Skeletal muscle Cardiac muscle
- 4. Skeletal Muscle striated muscle Consists of parallel bundles of long multinucleate fibres Produces the movements of the skeleton
- 5. Parts of the skeletal muscle Fleshy Part: belly, contractile Fibrous Part: Tendon or Aponerosis Less elastic Less vascular Resistant to friction Fleshy Belly Tendon
- 6. Each muscle fibre is an individual muscle cell It has an outer cell membrane called sarcolemma The cell cytoplasm is called sarcoplasm Nuclei are multiple, oval in shape and peripherally placed
- 7. Epimysium covers the entire muscle Perimysium surrounds fascicles Endomysium surrounds individual fibres
- 8. Epimysium covers the entire muscle Perimysium surrounds fascicles Endomysium surrounds individual fibres
- 9. Epimysium covers the entire muscle Perimysium surrounds fascicles Endomysium surrounds individual fibres Fascicle
- 10. Epimysium covers the entire muscle Perimysium surrounds fascicles Endomysium surrounds individual fibres Endomysium
- 11. Epimysium covers the entire muscle Perimysium surrounds fascicles Endomysium surrounds individual fibres Sarcolemma is the outer cell membrane sarcolemma Individual muscle cell
- 12. A tendon (sinew) is a tough band of fibrous connective tissue. Usually connects muscle to bone Consolodation of collagen fibres in the perimysium and epimysium. Maximises efficiency of the muscle in moving a bone Strong Collagen
- 13. Aponeurosis Some muscles (especially flattened muscles) are attached to each other. aponeurosis (pleural: aponeuroses) anterolateral abdominal wall a layer of a flat broad tendon shiny, whitish-silvery colour, histologically similar to tendons few blood vessels and nerves
- 14. Aponeurosis anterolateral abdominal wall Lumbar Palmer and planter scalp
- 15. like tendons tightly packed collagen bundles arranged in parallel respond to stress from a single direction attach bones to each other stabalise joints
- 16. KNEE JOINT
- 17. foetal remnant peritoneal fold
- 18. foetal remnant ligamentum arteriosum remnant of ductus arteriosus peritoneal fold ligamentum teres
- 19. layer of connective tissue superficial deep
- 20. layer of connective tissue superficial fascia - subcutaneous connective tissue - lies beneath / merges with dermis - fibro fatty layer -fibroblasts - aqueous matrix - elastin - collagen - fat - lymphatic tissue
- 21. deep fascia beneath the superficial fascia ensheaths muscles helps attach them to bones provides attachment for intermuscular septa which partitian muscle groups muscle compartments fibrous sparce fat and fluid thin and expansile substantial layers, very tough - esp. in neck & limbs non-expansile sleeves investing groups of muscles very thick bands retinacula
- 22. deep fascia The UP side of fascia movement minimal friction venous return in legs pus retained within a compartment The DOWN side of fascia important in disease potential spaces between fascia - track through between facial layers Compartment syndrome
- 23. A lubrication device - flattened, fibrous sacs lined with synovial membranes and containing a film of synovial fluid. Reduces friction between: - tendons and surrounding structures, or - bone and skin (e.g. prepatellar bursa) Occasionally bursae may communicate with the cavity of a synovial joint, e.g. the suprapatellar bursae of the knee joint, and the subscapularis bursae of the shoulder joint

Joints Joints = articulation or arthrosis Joints allow the movement of our body and hold it together. Joints include bones, ligaments, muscles,
11.2 Muscles and Movement. The joints in our body provide mobility and hold the body together. Most joints include the following: Bones Ligaments Muscles.
Muscles &Muscle Tissue Chapter 9. Function of Muscles Movement Posture Stabilization of Joints Thermogenesis (heat production)
General Info: -Muscles always pull and never push bones… ***Meaning during a joints movement phase muscles causing the movement can only pull the bones.
Muscular System Functions of Muscles Produce movement Maintain posture Stabilize joints Generate heat.
