1
Q

The site where two or more bones meet

A

joints

2
Q

The two fundamental functions of joints are

A

give our skeleton mobility & hold it together

3
Q

________ focuses on the material binding the bones together and whether or not a joint cavity is present

A

Structural Classification

4
Q

Three types of Structural classification are

A

Fibrous joint
Cartilaginous joint
Synovial joint

5
Q

Characteristic of Fibrous joint

A

Bones are joined by fibrous tissue
has no joint cavity
immovable joint

6
Q

Three types of Fibrous joints are

Suture
Syndesmoses
Gomphosis

7
Q

literally “seams” occurs between bones of the skull, allows the skull to expand as the brain grows during youth.

Suture

8

The closed sutures are precisely called

A

Synotoses

9
Q

The bones are connected by ligaments, little or no movement is allowed. located on the radius and ulna

A

Syndesmoses

10
Q

A peg-in-socket fibrous joint. example tooth with its bony alveolar socket. The fibrous connection in this case is the short periodental ligament

A

Gomphosis

11
Q

Characteristic of Cartilaginous joint

A

united by cartilage
lack a joint cavity
are not highly moveable

12
Q

Two types of cartilaginous joints are

A

Synchondroses

Symphyses

13
Q

A bar or plate of HYALINE CARTILAGE unites the bone is a _______, Ex: epiphyseal plates in long bones of children

A

Synchondrosis

14
Q

A joint where FIBROCARTILAGE unites the bone is a ________. Acts as a shock absorber and permits a limited amount of movement at the joint.Ex: intervertebral joints

A

Symphysis

15
Q

6 Special characteristic of Synovial joints

A
  • articular cartilage
  • joint (articular) cavity
  • articular capsule (fibrous layer, external) (synovial membrane makes synovial fluid, internal layer)
  • Synovial fluid (decrease friction)
  • reinforcing ligament
  • nerves and blood vessels (richly supplied)
16
Q

__________ is based on the amount of movement allowed at the joint

A

Functional classification

17
Q

Three types of Functional Classification are, and explain their movement

A

Synarthroses (immovable joints)
Amphiarthroses (slightly movable joints)
Diarthroses ( freely movable joints)

18
Q

________ improve the fit between articulating bones, making the joint more stable and minimizing wear and tear on the joint surfaces

A

Articular disc/menisci

19
Q

_______ flattened fibrous sacs lined with synovial membrane and containing a thin film of synovial fluid. Occur where ligaments, muscles, skin, tendon, or bones rub together

A

Bursae

20
Q

_______ an elongated bursa that wraps completely around a tendon subjected to friction like a bun around a hot dog. Common where several tendons are crowded together within narrow canals

A

Tendon sheaths

21
Q

the muscle’s ______ attached to the immovable or less immovable bone

A

origin

22
Q

the muscle’s ______ attached to the movable bone

A

Insertion

23
Q

non-axial movement is

A

sliding movements only, no axis

24
Q

uni-axial movement is

A

movement in one plane

25
Q

Bi-axial movement is

A

movement in two planes

26
Q

Multi-axial movement is

A

Movement in or around three planes of spaces and axes

27
Q

The three general types of movement are

A

Gliding, Angular, Rotation

28
Q

______ occurs when one flat or nearly flat bone surface slides or slips overs another, (back and forth, Side to side)

A

Gliding

29
Q

_____ increase or decrease the angle between two bones

A

Angular

30
Q

5 Angular movement includes and what are their actions

A
flexion (bending)
extension (straightening)
abduction (away from midline)
adduction (toward midline)
circumduction (moves in circle)
31
Q

_______ the turning of a bone around its own long axis. EX: Movement allowed only in the first two cervical vertebrae, hip and shoulder joint

A

Rotation

32
Q

Special movements, describe movement of Supination and Pronation

A

Sup> palm faces superiorly, radius and ulna are parallel

Pro> palm faces inferiorly , radius and ulna form X

33
Q

Special movements, describe movement of Dorsiflexion and Plantar flexion

A

Dors> lifting the foot towards the shin

Plan> pointing the toes

34
Q

Special movements, describe movement of Inversion and Eversion
