Functions and Properties of Muscular Tissue

Question 1

What are 4 functions of muscular tissue?

Answer 1

produce body movement
stabilising body position
storing and moving substances with the body
producing heat

Question 2

How does muscular tissue produce body movement?

Answer 2

in association with the skeletal system

Question 3

How does muscular tissue stabilize body position?

Answer 3

-continuous muscle contraction & muscle tone keep the body in upright position
-muscles and tendons crossing over joints

Question 4

How does muscular tissue store and move substances within the body?

Answer 4

-cardiovascular system
-sphincters allow temporary storage
-digestive tract

Question 5

How does muscular tissue produce heat?

Answer 5

-via metabolism or movement of tissue itself
-normal muscle contraction maintains body temp
-shivering increases body temp

Question 6

What are 4 properties specific to muscular tissue?

Answer 6

electrical excitability
contractility
extensibility
elasticity

Question 7

What does electrical excitability look like in muscular tissues?

Answer 7

-responds to stimulus (electrical or chemical) by producing electrical signal called action potential

Question 8

What does contractility look like in muscular tissues?

Answer 8

-ability to contract forcefully when stimulated
-muscle contracts to about 70% of resting length when stimulated

Question 9

What does extensibility look like in muscular tissues?

Answer 9

-muscle tissue can be stretched within certain limits without damage

Question 10

What does elasticity look like in muscular tissues?

Answer 10

-muscle tissue returns to original length and shape after contraction or extension
