Joint Flexibility (aka Range of Motion = ROM) may also be affected by:

1) Shape/structure of __________ bones

2) Flexibility of _______ (bone-to-bone)

3) Tension/Arrangement of muscles & ______ (muscle-to-bone)

4) Contact of ____ parts, which likely decreases range of motion

5) _________ (e.g relaxin softens pelvis joints when pregnancy / childbirth)

6) Disuse - The ____ you use it, the ____ it wears

1) Articulating. The tighter they are together, the less motion you’re going to have

2) Ligaments

3) Tendons. Parallell, circular, etc

4) Soft

5) Hormones

6) less, less

2

The Articular Disc in the knee, aka ________; is made of ________ pads and located between the articulating bones. 

Meniscus

Fibrocatilage

3

Bursae (sac-like) - between skin & ____, tendons & ____, muscle & ____, ligaments & ____;

bones (all)

4

Dense

5

Syndesmosis - distal articulation between ____ & _____; and is ______ (not, slightly, very) movable

Tibia, Fibula

Slightly

6

What do you call the:

Sheet of fibrous tissue binding two neighboring bones together; (slightly moveable); between radius & ulna and tibia & fibula

Interosseous membrane

 

 

7

Cartilaginous Joints are a tight articulation, made of either ______ cartilage or ____cartilage)

hyaline, fibrocartilage

8

Hyaline cartilage connecting material epiphyseal (growth) plate between epiphysis and diaphysis; (immovable) becomes ossified is called the Syn________

Synchondrosis

9

What joint is the hyaline + fibrocartilage connecting material occurs at intervertebral joints; (slightly movable)

Symphysis

21

Which type of muscle tissue has intercalated discs w/ Gap junctions?

Cardiac Muscle Tissue

22

What are the 4 main functions of the muscle system, and which types of muscle tissue contribute to each?

1. Produces body movements e.g. running, walking, etc. (skeletal muscles)

2. Stabilizes body positions e.g. sitting & standing (skeletal)

3. Stores & moves substances within the body e.g. sphincters open/close to regulate contents in stomach and urinary bladder (smooth) e.g. heart pumps blood, moves food thru GI tract, aids in returning blood to heart (cardiac, smooth, skeletal)

4. Produces heat (thermogenesis) e.g. shivering (skeletal)

23

Thermogenesis is a fancy word for when your body _________ via the help of your skeletal muscle tissue

Produces heat

24

Specifically, which muscle tissue type allow your sphincters to open/close to regulate contents in stomach and urinary bladder

Smooth

25

Which muscle tissue types enable:

 

Heart pumps blood, moves food thru GI tract, aids in returning blood to heart

All 3: skeletal, cardic, and smooth

26

What are the 4 characteristics of Muscle Tissue? Explain each.

1. Excitable (e.g. muscle & nerve cells) – responds to stimuli via action potentials (electrical impulses)

2. Contractible – (usually) shorten in length when stimulated

3. Extensible – can stretch

4. Elastic – returns to shape after contraction

27

Skeletal Muscles are made up of bundles of muscle fibers called ______.
