  • Front

Name and describe three muscle types.
•Skeletal muscle- straitied; voluntary; multinucleated
•Smooth muscle –non striated; involuntary, visceral organs, spindle shaped
•Cardiac muscle – striated; incalulated discs; branching cells
Skeletal muscle
straitied; voluntary; multinucleated
Smooth muscle
non striated; involuntary, visceral organs, spindle shaped
Cardiac muscle
striated; incalulated discs; braching cells
Explain voluntary muscle contraction in terms of initiation, fiber response, muscle group action, and
actual physical response.(Cellular Level)
Neuromuscular junction, SR response release, Ca ions from T tubules; Sliding Filament Theory;
Explain voluntary muscle contraction in terms of initiation, fiber response, muscle group action, and
actual physical response.Muscle Group
Twitch - Trepp, wave summation, tetanous
isometric
increased muscle tension without
shortening of sarcomere
isotonic
shortening of sarcomere without
increased muscle tension
Describe the microscopic anatomical arrangement of muscle tissue.
Sarcomere, Z-disk, moycin (thick) and action (thin)
Describe the physiologic or metabolic function of muscle tissue.
Requirements - ATP and Ca ions
Supply of ATP
3 Sources - Ox phosphorylation (myoglobin), phosphagen system, Lactic Acid (muscle fatigue)
Neuromuscular junction
region where motor neurons comes into close contact with a skeletal muscle cell.
Sarcoplasmic Reticulum
an elaborate smooth endoplasmic reticulum;
involved in producing the energy used during muscle contraction
Major role of the SR is to regulate intracellualar levels of CA++
T Tubles
increases the muscle fibers surface area
continuation of the sarcolemma; conduct impulsed to the deepest part of the muscle which signal the release of CA++
Sliding filament theory
during contraction the thin filament (Actin) slides past the Thick (Myosin) so that the actin and the myosin overlap to a greater degree
