1

What are the functional classification of articulations: Based on movement

Synarthrosis
amphiarthrosis
diarthrosis

2

What type of functional classification of articulations: Based on movement is this?

________:are immobile joints like the sutures found between the bones of
the cranium.

Synarthrosis

3

What type of functional classification of articulations: Based on movement is this?

_______:are joints that allow a slight amount of movement like the
intervertebral discs made of fibrocartilage found between the bodies of adjacent vertebrae.

Amphiarthrosis

4

What type of functional classification of articulations: Based on movement is this?

_______:are freely movable articulations and include many familiar
examples such as the elbow, shoulder, and knee

Diarthrosis

5

What are the structural classification of articulations?

Fibrous joints
Cartiliginous joints
Synovial joints

6

What type of structural classification of articulations is this?_______- held together by dense fibrous CT
• _______- fibrous synarthrosis
o ex: cranial sutures
• ______- ligament connects bones
o ex: distal radio-ulnar joint
• ________- ligament holds teeth to dental alveoli
• _______- two bones fuse
o ex: epiphyseal lines, coxal bones (ilium, ischium and pubis fuse), frontal bone
(left and right fuse)

****Fibrous joints
*Suture
*Syndesmosis
*Gomphosis
*Synostosis

7

What type of structural classification of articulations is this?
______- held together by cartilage
• _______- cartilaginous synarthroses ex: sternocostal joints
• _________- amphiarthroses of fibrocartilage ex: pubic symphysis

****Cartiliginous joints
*Synchondrosis
*Symphysis

8

What type of structural classification of articulations is this?
______-capsule of fibrous CT surrounding a fluid filled cavity ex: all diarthroses

Synovial Joint

9

Types of movements:
16 types

Flexion
Extension
Dorsiflexion
Plantar flexion
abduction
Rotation
Protation
Supination
Elevation
Depression
Circumduction
Inversion
Lateral flexion
protraction
Retraction

10

Types of movements:
_______moves away from anatomical position through sagittal plane

Flexion

11

Types of movements:
______:opposite of flexion returns to anatomical position

Extension

12

Types of movements::
______:raises the toes superiorly

Dorsiflexion

13

Types of movements:
______:pushes the toes inferiorly

Plantar Flexion

14

Types of movements:
________:move away from the longitudinal axis in frontal plane

_____opposite
of abduction returns to anatomical position

Abduction
Adduction

15

Types of movements:
_______-turn around long axis of bone. The head is along the midline so we can
rotate the head left or right. The limbs can rotate lateral away from the midline or medial
toward the midline.

Rotation

16

Types of movements:
_______-medial rotation of forearm

Pronation

17

Types of movements:
_____- opposite of pronation returns to anatomical position

Supination

18

Types of movements
______-raise superior ex: closing the jaw

Elevation

19

Types of movements
______- lower inferior, opposite of elevation ex: opening the jaw

Depression

20

_______ is a combination of flexion, extension, adduction and abduction.
Example: hand moving in a circle, eyes

Circumduction

21

_____ moving the foot (pedal) laterally

inversion

22

____ moving foot (pedal) medially.

eversion

23

___ moving your body laterally.
EX: moving vertebral laterally, or moving your head side to side.

Lateral flexion

24

______ is movement of a body part in the anterior direction, i.e. being drawn forwards
Ex; moving (scapula) shoulder blades inward.

Protraction

25

______is movement of the body part in the posterior direction.
Ex; Moving shoulder blades ( scapula) outward.

Retraction

26

Types of synovial Joints:

Piviot joint
Hinge joint
Saddle joint
Plane joint
Condyloid joint
Ball- and- socket joint

27

What Types of synovial Joints is this?
______- allows rotation only
• ex: Atlantoaxial joint between C1 and C2, Proximal radioulnar joint

Pivot Joint

28

What Types of synovial Joints is this?
_____- allows angular motion of flexion/extension
• ex: Elbow or Knee

Hinge Joint

29

What Types of synovial Joints is this?
_______- surface concave on one axis convex on other enables flexion and
abduction
• ex: Carpalmetacarpal joint between the trapezium and the first metacarpal

Saddle Joint

30

What Types of synovial Joints is this?
________- allows a small amount of sliding
• ex: Intercarpal joint between the scaphoid and trapezium, Clavicle and sternum

Plane Joint

31

What Types of synovial Joints is this?
______-oval face in a depression allows flexion and abduction
• ex: Metacarpalphalangeal joints

Condyloid joint

32

What Types of synovial Joints is this?
_______- flexion, abduction, rotation, and circumduction.
• Ex: Shoulder and hip

BAll- and -Socket joint
