Chapter 9 The Joints
1. When you raise your chin and look up to the stars, what motion is it that is occurring at the
neck? Hyperextension
2. Name the 3 classifications of joints, by their ability to move from MOST mobile to least.
Diarthrosis, amphiarthrosis and synarthrosis.
Which, by classification of the tissue that makes up the joint, cannot be fibrous? Diarthrodial
joints/Diarthroses
3. Whenever we are chewing the 2 motions of the mandible are? Elevation and depression
4. The joints between the carpal and tarsal bones are slightly moveable. What term would you
use to classify these joints? Amphiarthrodial
5. An injury to the rotator cuff would involve which joint? Shoulder
Name the 4 muscles whose tendons make up the rotator cuff. Supraspinatus, Infraspinatus,
Teres minor and Subscapularis
6. When we communicate non-verbally to say yes, our we flex and extend our heads. How does
the head move when we say “no”? It rotates left and right
Which specific vertebra, by name and number, allows for the majority of this motion? C2 – Axis
And, what type of joint, specifically, is it classifies as? Pivotal
7. A ballerina often goes up on her toes to perform a pirouette. What specific movement is
being performed at the ankle joint? Plantar flexion
8. You see and old friend and you go to give that person a big hug, only that person is YOU and
you’re hugging yourself! What is happening to your shoulder blades during this action? They
are protracted
9. What is the definition of a synarthrosis? Two bones that articulate an allow for little-to-no
movement
10. A see-saw or teeter totter, as some people call it, would represent what is known as a
“second-class lever” because its pivot point in in the middle of 2 forces that can make the board
we sit on move up and down. Would you consider a situation where we nod our head in a
gesture to say “yes” the same type of lever set-up? Yes

, 11. Name the 2 substances that make up synovial fluid. Albumin and hyaluronic acid
Synovial fluid is often compared to this specific substance of the eggs that we egg. The white of
the egg.
12. Cupping the hands together to hold something in them would involve pronation of the
forearms, but most importantly, what movement of the fingers? Adduction

14. Please name the 4 muscles that goes with the acronym, S.I. T.S. Supraspinatus,
Infraspinatus, Teres minor and Subscapularis
15. In which specific structure does the humerus articulate with the scapula? The glenoid cavity
The tendon of this specific muscle holds the joint more securely than any other structure? The
biceps brachii
16. We find menisci, or cartilaginous pads in the knee, we also may find them in what other
joints? The temporomandibular joint (TMJ)
17. What are proprioceptors? They are sensory nerve endings that monitor joint angle and
tension in tendons, ligaments and muscles
18. What exactly is the Achilles “heal”? It is a tendon, the calcaneal tendon
19. Crepitus is a crunching/crackling sound that often appears in aging joints. What causes this?
Movement involving roughened cartilaginous surfaces
20. If you are sitting in your car and you raise your arm to put it on the seat next to you, what is
the primary movement taking place at the shoulder joint? Abduction
21. If a police officer raises his hand as if to say, “Stop your vehicle”, what is the movement that
is taking place at the shoulder? Flexion
What movement would be taking place at the wrist? Hyperextension
22. What specific type of joint is formed by the patella and femur? A gliding joint
23. The pubic symphysis and the discs of the spine are made of this type of cartilage.
Fibrocartilage
24. With which joint would you associate the “olecranon bursa”? The elbow joint
25. Is a meniscus made of the same cartilage found in the pubic symphysis and vertebral discs?
