1

the place of contact between bones, between bone and cartilage, or between bones and teeth.

joint or articulation

2

Bones are said to _____ with each other at a joint.

articulate

3

The scientific study of joints is called ___.

arthrology

4

Joints are classified by both their structural characteristics and the ____ they allow.

movements

5

Joints are categorized structurally on the basis of whether a space occurs between the _____ and the type of connective tissue that binds the articulating surfaces of the bones.

articulating bones

6

has no joint cavity and occurs where bones are held together by dense regular (fibrous) connective tissue.

fibrous joint

7

has no joint cavity and occurs where bones are joined by cartilage

cartilaginous joint

8

a fluid-filled joint cavity that separates the articulating surfaces of the bones. the articulating surfaces are enclosed within a connective tissue capsule, and the bones are attached to each other by various ligaments.

synovial joint

9

Joints are classified into 3 different structural categories

fibrous
cartilaginous
synovial

10

Joints are classified into 3 different functional categories based on the extent of the movement that permit

synarthrosis
amphiarthrosis
diarthrosis

11

_______ is an immobile joint. two types of fibrous joints and one type of cartilaginous joint are _______.

Synarthrosis
synarthroses

12

An _____ is a slightly mobile joint. One type of fibrous joint and one type of cartilaginous joint are _____.

amphiarthrosis
amphiarthroses

13

A ________ is a freely mobile joint.

diarthrosis

14

All synovial joints are ____.

diarthroses

15

The _____ of each joint determines both its mobility and its stability.

structure

16

When the mobility of a joint increases, its stability ______.

decreases

17

If a joint is immobile, it has ____ stability.

maximum

18

Structural characteristics of a _____ joint include dense regular connective tissue that holds together the ends of bones and bone parts; no joint cavity.

fibrous

19

Structural characteristics of a ____ joint include a pad of cartilage that is wedged between the ends of bones; no joint cavity.

cartilaginous

20

Structural characteristics of ____ joint include the ends of bones covered with articular cartilage; joint cavity separates the articulating bones; joint enclosed by an articular capsule, lined by a synovial membrane; contain synovial fluid.

synovial

21

Three structural categories of fibrous joints.

gomphosis
suture
syndemosis

22

Two structural categories of cartilaginous joints.

synchondrosis
symphysis

23

Three structural categories of synovial joints.

Uniaxial
Plane joint
Hinge joint
Pivot joint
Biaxial
Condylar joint
Saddle joint
Multiaxial (Triaxial)
Ball and socket joint

24

periodontal membranes hold tooth to bony jaw

gomphosis
i.e. tooth to jaw

25

dense regular connective tissue connects skull bones

suture
ie. Lamboid suture (connects occipital and parietal bones)

26

dense regular connective tissue fibers between bones

syndesmosis
i.e. articulation between radius and ulna, and between tibia and fibula

27

hyaline cartilage between bones

synchondrosis
i.e. epiphyseal plates in growing bones; costochondral joints

28

fibrocartilage pad between bones

symphysis
i.e. pubic symphysis; intervertebral disc articulations

29

flattened or slightly curved faces slide across one another

plane joint
i.e. intercarpal joints, intertarsal joints

30

convex feature of one bone fits into concave depression of another bone

hinge joint
i.e. elbow joint, knee joint
