Trident tech Bio 210 section 015
1. Somatic movement
2. Maintaining posture
3. Stabilizing moveable joints
4. Supporting & protecting organs
5. Voluntary control for openings of digestive and urinary tracts
6. Heat-generating effectors for thermoregulation - correct answer-what are the six main
functions of skeletal muscles?
Sarcolemma - correct answer-what is the name for the plasma membrane of a muscle cell?
Sarcolemma - correct answer-what membrane is specialized for conduction action
potentials?
Sarcoplasm - correct answer-what is the name for the cytoplasm of a muscle cell?
Sarcoplasm - correct answer-what cytoplasm is specialized for contraction?
Myofilaments - correct answer-what is the name given to the cytoskeletal protein fibers?
Myofilaments - correct answer-what muscle structure is specialized for contraction thick
filaments and thin filaments?
Visceral muscle tissues - correct answer-what muscle tissue is known as an involuntary
muscle tissues of internal organs & skin?
Gap junctions - correct answer-This junction allows neighboring visceral muscle cells to
coordinate contraction?
Direct signaling - correct answer-what type of signaling is used in visceral muscle cells
relase cytosolic chemical signals through gap junctions, causing the next cell to behave like
the first cell?
Smooth muscle - correct answer-visceral muscle in skin & all internal organs
Cardiac muscle - correct answer-viscreal muscle in the heart wall
Striated muscle tissues - correct answer-muscle tissues with cells that contain myofibrils
Myofibrils - correct answer-these fibrils in muscles produce stronger contractions but readily
fatigue the cell.
hint: smooth muscle cells don't have these
Striations: transverse stripes in cytoplasm, alternating light stripes (I bands) & dark stripes (A
bands), due to many myofibrils packed side-by-side with their sarcomere (see below)
