What are the three different joint classifications?

Fibrous joints, Cartilaginous joints, synovial joints.

1

What are the types of fibrous joints?

Sutures, syndesmosis, dentoalveolar syndesmosis.

2

What are types of cartilaginous joints?

Primary Cartilaginous joints, secondary cartilaginous joints.

3

What are the six types of synovial joints?

Plane, hinge, saddle, condyloid, ball and socket, but if it.

4

What are the most common type of joints?

Synovial joints.

5

Under which joint type does the intervertebral discs or pubic synthesis fall?

Cartilaginous joints ->secondary cartilaginous joints.

6

What do the primary cartilaginous joints do?

Permit slight bending in early life, usually temporary unions, permit growth in the length to the long bone, eventually calcifying and fuse.

7

What joints provide sock absorption and flexibility to the vertebral column?

Secondary cartilaginous joints.

8

What unites cartilaginous joints?

Hyaline Cartlidge or fibrocartilage.

9

Given example of a joint that is syndesmosis.

Interosseous membrane that joins radius and ulna.

10

The root of tooth and Alveolar process of jaw is what type of joint?

Dentoalveolar syndesmosis.

11

Synchondrosis is part of what type of joint?

Primary cartilaginous joints.

12

What types of synovial joints are uniaxial?

Plane, Hinge, pivot.

13

Which synovial joints are biaxial?

Saddle, condyloid.

14

Which synovial joints are multi axial?

Ball and socket.

15

What are the planes and axis of the following synovial joints, hinge, saddle, condyloid, pivot, plane?

Plane: movements in plain of articulating surface.
Hinge: sagittal plane around a single transverse axis.
Condyloid: movement in sagittal plane being Freer.
Pivot: Central axis.

16

What does Hiltons law state?

It states that nerves supplying a joint also supply the muscles moving a joint in the skin covering their distal attachments.

17

What two things should I consider under the topic of joint vasculature?

Articular arteries and articular veins.

18

Where do articular arteries arise from when considering joint vasculature?

They arise from vessels around the joint.

19

Often anastomose or communicate to form networks. Periarticular anastomoses.

Articular arteries. Which ensure blood supply to and across joint in the various positions assumed by joint.

20

Which communicating veins accompany arteries?

Articular veins.

21

What two things should I consider under the topic, joint innervation?

Hilton's law and articular nerves.

22

Most of these are branches of nerves that supply muscles that cross and move joint.

articular nerves.

23

Where are articular nerves located?

Distally hands and feet their branches of cutaneous nerves that supply overlying skin.

24

What is the function of articular nerves?

Transmit sensory impulses that contribute to sense of proprioreceptors in. Provides awareness of movement and position of the parts of the body.
