From lecture and lab you should be able to:
Describe ultrastructural and histological characteristics of skeletal, cardiac and smooth muscle.
Understand cellular and macromolecular mechanisms governing regulated muscle contraction.
Understand basic adaptive and regenerative capacities of each muscle type.
Name specialized structures – spindle, etc
Skeletal, smooth, cardiac, striated, intercalated disc, t-tubule, sarcoplasmic reticulum,
sarcolemma, epi-, peri-, and endomysium. Fast twitch v slow twitch. Glycolytic, oxidative. Z, I, A, H and M
bands. Actin, myosin, actinin. Intermediate filaments, sarcomere, calmodulin
There are three human muscle types:
striated, usually voluntary contractions
Skeletal and cardiac muscles are BOTH striated, BUT cardiac fibers branch
- position of nuclei - Smooth and cardiac centrally located, skeletal on the periphery as shown bel
