3ו UILIUIו 1CG1 tמ Io • Electn • Na+ diffuses into the cell • K+ diffuses into the cell Inside the cell Sodium-potassium pumps 13. Muscles have 5 basic properties that allow them to cause movement: excitability (stimulated by neurons), conductivity (carry electrical charge), contractility (able to shorten), extensibility (able to lengthen), and elasticity (able to "spring" back into place). Electricity is the movement of charged ions. What does it mean when we say that muscles can "carry an electrical charge" (conductivity)? In your answer, explain what happens in the muscle cell (hint: it involves Na+ and K+). auilque to What molecule gives muscles their elasticity? Titan In your own words, explain the "sliding filament theory" and how it relates to muscle shortening (contractility): %3D
