Question

13. You don't need to do anything here, but be sure you know the terminology for each of the characteristics used to name muscles [deltoid-triangle, rhomboid = diamond-shaped, oblique diagonal to midline etc.] I recommend you make flashcards for the ones you don't know and are not obvious). 14. List and differentiate between the 4 characteristics of muscle tissue. 15. Describe the connective tissue set up in the microanatomy of the muscle. Name two advantages for this set up. 16. Describe how the capillaries in a muscle are organized/situated. What is the advantage of this set up? 17. Draw a flow chart that shows the progression of the general skeletal muscle structures from largest to smallest (sarcomere). Also include the CT that wraps each. I'll start you out.

Answer 1

A. 15 - Connective tissue. Connective tissue is a tissue that fills the Interstitium between more specialsed elements. Components of connective tissue : Cells, fibers, Extracellular matrix tissue Connective set up in microanatomy of the muscle. Perimysium Suspoline bundle of muscle fibess Epimysium muskle of . Endomysium , around andividual muscle fibers The muscle fibers are arranged in the form of bundles or fasciculi .. Each muscle fiber is closely invested by connective tissue Three layers Tendomysium Scanned with CamScanner Epimysium Perimyšium

Endomysium - each musele fiber surrounds by delicate connective tissue that is called endomysium. Perimysium- Individual fasciculi are surrounds by stronger sheath of connective tissue that is called perimysium. Epimysium - mysium - eping Entire muscle surrounds by connective tissue called epimy sium. * If the junction of muscle, with tendon the fibers of endomysium, pesimysium and epimysium un to become continous with fibers of tendon Advantages :- connective tissue supports muscle fibers. • unites them to each o each other.

A16 Skeletal muscle. Arrangement of capillaries in with sichley supplied s AI Skeletal muscle is sichlay supplies blood vessels. The main artery to the muscle enters it at the neurovascular hilus. Asteries form plexus arround the muscle in the epimysium and in the perimysium. Then end in capillaries that surrounds each muscle fibers. Capillaries Carand netravels are embedded in parallel to muscle endomysium fibers.

Advantages: supplies blood to call muscle fibers and cells. helps in richly supply of blood. Scanned with CamScanner
