muscle structure and function

Question 1

what are the properties of muscle?

Answer 1

excitablility, contractibility, extensibility, elasticity

Question 2

Excitability

Answer 2

is the property that muscles can be activated by stimulation.

Question 3

contractibility

Answer 3

When the muscle is stimulated cross-brides between actin and myosin in the sarcomeres produce force in the direction of shortening the muscle

Question 4

extensibility

Answer 4

Simply, muscle cells can stretch.

Question 5

elasticity

Answer 5

When you extend/stretch a muscle it stores elastic energy that is recovered when the muscle and tendon is released, and it returns to original length. Like flicking an elastic band.

Question 6

muscle shortens =

Answer 6

concentric contraction

Question 7

muscle lengthens =

Answer 7

eccentric contraction

Question 8

muscle remains constant length =

Answer 8

isometric contraction

Question 9

muscle with more force=

Answer 9

muscle lengthened

Question 9

muscle with less force=

Answer 9

shorter

Question 10

muscle have a ——— structure

Answer 10

hierarchal

Question 11

is series or parallel arrangement better for force

Answer 11

parallel
