Answer 9

Around the bone (whole thing )

Question 10

Concentric lamellae

Answer 10

Around central canals

Question 11

Osteopenia and osteoporosis effects

Answer 11

Loss of compact bone, thinning of cancellous trabeculae, leading to compression fractures

Question 12

Fibrocartilage purposes

Answer 12

Shock absorption, weight bearing, deepen articular surfaces for stability

Question 18

Secondary skeletal muscle jobs:

Answer 18

Supporting and protecting soft internal organs, voluntary control of openings, converts energy to heat for core temp

Question 19

Muscle overall structure

Answer 19

Fibers (many nuclei), fascicles, and muscles have blood vessels and nerves all sheathed in connective tissue which gathers into tendons.

Question 20

Muscle recruitment

Answer 20

Neurons control different groups and so diff numbers of fibers can be recruited depending on which neurons are active

Question 21

Muscle strength determiners

Answer 21

Number of fibers recruited ( neuron activity), frequency of signal

Question 22

Types of muscle signals

Answer 22

Twitch, summation, tetanus

Question 23

Why does frequency of signal matter for muscle contraction

Answer 23

Time to relax in between, also ca + concentration

Question 24

Antagonist

Answer 24

Act eccentrically to oppose and control movement

Question 25

When are long muscle fibers needed?

Answer 25

Larger ROM
