of synovial joints?
a) Contain a joint cavity
b) Are freely moveable
c) Articulating bones are covered with hyaline cartilage
d) Include elastic cartilage
e) Have ligaments holding the joint together

Answer 7

d) Include elastic cartilage

Question 8

What structures are used to reduce friction in joints?

Answer 8

1. Bursae

2. Synovial fluid

Question 9

Which type of motion results from relatively flat bone surfaces moving back and forth and from side to side with respect to one another?

Answer 9

Gliding

Question 10

Moving the humerus laterally at the shoulder joint is an example of which type of movement?

Answer 10

Abduction

Question 11

Which type of movement involves a continuous sequence of flexion, abduction, extension, and adduction resulting in a distal body part moving in a circle?

Answer 11

Circumduction

Question 12

Which special movement occurs when you bend your foot at the ankle in the direction of the foot’s superior surface as would occur when you balance on your heels?

Answer 12

Dorsiflextion

Question 13

Which special movement involves moving your thumb across the palm to touch the tips of the fingers on the same hand?

Answer 13

Opposition

Question 14

Which of the following is NOT a structural category of synovial joints?

a) Planar
b) Hinge
c) Condyloid
d) Suture
e) Saddle

Answer 14

Suture

Question 15

In which type of synovial joint does a rounded or pointed surface on one bone articulate with a ring formed partly by another bone and partly by a ligament?

Answer 15

Pivot joint

Question 16

A condyloid joint

Answer 16

a) is also called an ellipsoidal joint.
b) is considered to be biaxial.
c) allows both flexion–extension and abduction–adduction of the joint.
d) can be found in the wrist.

Question 17

what is a syndesmosis joint?

Answer 17

A syndesmosis is defined as a fibrous joint in which two adjacent bones are linked by a strong membrane or ligaments.

Question 18

What is a gomphosis joint?

Answer 18

A gomphosis is a fibrous mobile peg-and-socket joint. The roots of the teeth (the pegs) fit into their sockets in the mandible and maxilla and are the only examples of this type of joint.

Question 19

What joint is found at the elbow and its movements?

Answer 19

Hinge joint

This joint allows uni-direction movement of flexion and extension only.

Question 20

What joint is found at the thumb?

Answer 20

Saddle
The articular surfaces are concave and convex and allow a wide range of movements. The 1st carpometacarpal joints are examples.

Question 21

What is a plane joint, with examples?

Answer 21

The articular surfaces are flat and allow gliding movements. Other examples are the intercarpal and intertarsal joints.

Question 22

What are Condylar / Ellipsoid and where they found

Answer 22

Otherwise known as condyloid (knuckle-like, not to be mistaken for Condylar). They resemble saddle joints but have less movement.
Between metacarpals and phalanges

Question 23

Sutures, syndesmoses and gomphoses are three types of which joint classification?

Answer 23

Fibrous Joints

Question 24

Which type of joint are the joints between the vertebral bodies?

Answer 24

Symphysis
This is a cartilaginous joint. The ends of the bone are covered with hyaline cartilage and are joined by a disc of fibrocartilage. Movements are variable.
