Monday Anatomy Test Part 2 Study

Question 1

What are the four functions of muscle tissues?

Answer 1

1) to contract to produce force for motion
2) thermogenesis
3) stabilizes body positions
4) regulates organ volume

Question 2

what characteristics are use in naming skeletal muscles?

Answer 2

size, shape, location, action, direction of fibers, number of origins, origin/insertion, position

Question 3

ways the body increases flow of oxygen rich blood to working muscles:
