4

Joints are classified into these 2 major categories:

- Structural - Functional

5

Structural system is base on (2):

1. Presence of fluid filled joint space 2. Type of connective tissue

6

Functional system is based on:

type of movement allowed at the joint

7

Name the structural and functional type of joint: - No joint cavity -Bones of joints fit closely together - 3 types (syndesmoses, sutures, gomphoses

Structural: Fibrous Joints Functional: Synarthroses

8

joints in which fibrous bands (ligaments) connect 2 bones slightly movable

Syndesmoses

9

joints: - found only in the skull - have a thin layer of fibrous connective tissue - adjacent bones interlock with each other - slight movable joint in children - immovable in adults-become ossified

Sutures

10

frontal bone suture that is ossified (has no connective tissue)

Synotosis

11

joint: - formed between the root of a tooth and the sockets (alveoli) of the mandible or maxillae - immovable joint when healthy

Gomphoses

12

Fibrous tissue between root and bone in gomphoses joint

periodontal membrane

13

Name the structural and functional type of joint: - no joint cavity - bones of joints are joined together by hyaline cartilage or fibrocartilage - allow no motion to very little motion - 2 types (synchondroses, symphyses)

Structural: Cartilaginous Functional: Amphiarthroses

14

joint: - connecting material between articulating bones is hyaline cartilage - immovable

Synchondroses

15

joint: - with a pad or disc of fibrocartilage between 2 bones - most occur in midline of body - slight movement

Symphyses

16

Name the structural and functional type of joint: - freely movable - most numerous and anatomically complex joints - comprise a majority of the joints in the appendicular skeleton

Structural: Synovial Joints Functional: Diarthroses

17

Structure of synovial joints (7):

1. Joint capsule (2 layers) 2. Synovial membrane 3. Articular cartilage 4. Joint cavity 5. Menisci 6. Ligaments 7. Bursae/Tendon sheath

18

The ____ _____ forms a complete casing around a synovial joint

joint capsule

19

The ____ ____ lines the inner surface of the joint capsule, and attaches to the margins of the articular cartilage

synovial membrane

20

2 functions of the synovial membrane:

- lubricates - nourishes

21

Thin layer of hyaline cartilage that covers the articular surfaces of bones and reduces friction during movement, as well as absorbs shock

articular cartilage

22

small space between bones that allows for extensive movement

joint cavity

23

pads of fibrocartilage between articulating bones that usually divide the joint cavity into 2 separate spaces; allowing separate movements

Menisci (articular disks)

24

4 functions of menisci:

- shock absorption - better fit between articulating bones - larger contact surface for weight bearing - synovial fluid distribution across joint surfaces

25

fibrocartilaginous lip that extends from joint socket and increases contact area between bones

Labrum

26

____ deepens joint socket of shoulder and hip

labrum

27

strong cords of dense, regular fibrous tissue that hold bones of synovial joint together more firmly

ligaments

28

sac-like structure surrounded by synovial membrane. It is filled with synovial fluid, and found between skin and bones, tendons and bones, muscles and bones, or ligaments and bones.

Bursae

29

_____ cushion joint or facilitate movement of tendons

bursae

30

tube-like bursae that wrap around tendons that receive a lot of wear and tear

Tendon (synovial) sheaths

31

____ are extension of the joint capsule but wraps around tendon. It protects tendon as it slides back and forth with movement.

Tendon (synovial) sheaths

32

The 3 types of synovial joints are:

- uniaxial - biaxial - multiaxial

33

synovial joints that permit movement around 1 axis and in only 1 plane

Uniaxial

34

pivot joints and hinge joints are types of _____ synovial joints.

uniaxial

35

the convex surface of one bone fits into the concave surface of another bone

hinge joints

36

a projection of one bone articulates with a ring or notch of another bone

pivot joints

37

synovial diarthroses that permit movement around 2 perpedicular axes in 2 perpendicular planes

biaxial

38

articulating ends of the bones resemble reciprocally shaped miniature saddles these are only in the thumb

saddle joints

39

joint where condyle fits into an elliptical socket

Condyloid (ellipsoidal) joints

40

The distal end of the radius fitting into the depression of the carpal bones (scaphoid, lunate, triquitrum) is an example of what type of joint?

Condyloid, biaxial, synovial joint

41

Synovial joints that permit movements around 3 or more axes in 3 or more planes

multiaxial

42

The shoulder joint is an example of what type of joint?
