Answer 4

Semi moveable

Question 5

Answer 5

Completely; can move freely

Question 6

Answer 6

Skull, pelvis, radio ulnar and sacrum

Question 7

Answer 7

Ribs attached to the sternum

Question 8

Examples of synovial joints

Answer 8

Answer 9

6

Question 10

What is the structure of a pivot joint?

Answer 10

A uniaxial joint that only allows rotation

Question 11

What is the structure of a gilding joint?

Answer 11

Occurs where flat bones glide past each other, usually in a biaxial matter

Question 12

What is the structure of a ball and socket joint?

Answer 12

A rounded bone head articulates with a cup-shaped cavity

Question 13

What is the structure of a hinge joint?

Answer 13

A uniaxial joint

Question 14

What is the structure of a saddle joint?

Answer 14

Concave and convex bone surfaces align; generally biaxial

Question 15

What is the structure of a condyloid joint?

Answer 15

Very similar to a hinge joint but also allows slight rotation; hence, is biaxial

Question 16

Types of movement at pivot joints

Answer 16

Rotation of one bone around another

Question 17

Types of movement at gliding joints

Answer 17

Gliding movements

Question 18

Types of movement at ball and socket joints

Answer 18

Flexion, extension, adduction, abduction, internal and external rotation

Question 19

Types of movement at hinge joints

Answer 19

Flexion, extension

Question 20

Types of movement at saddle joints

Answer 20

Flexion, extension, adduction, abduction, circumduction

Question 21

Types of movement at condyloid joints

Answer 21

Flexion, extension, adduction, abduction, circumduction

Question 22

Example of a pivot joint

Answer 22

Atlas (top of neck)

Question 23

Examples of a gliding joint

Answer 23

Carpals/tarsals

Question 24

Examples of a ball and socket joint

Answer 24

Shoulder, hip

Question 25

Examples of a hinge joint

Answer 25

Knee, elbow

Question 26

Examples of a saddle joint

Answer 26

Thumb

Question 27

Examples of a condyloid joint

Answer 27

Wrist

Question 28

Define Flexion

Answer 28

The angle between articulating bones is decreased. Muscles responsible are flexors

Question 29

Define Extension

Answer 29

The angle of the joint is increased; muscles responsible for extension are known as extensors

Question 30

Define Abduction

Answer 30

The movement of a body part away from an imaginary mid line of the body

Question 31

Define Adduction

Answer 31

Movement of a body part towards an imaginary midline of the body

Question 32

Define rotation

Answer 32

When a bone turns on its own axis within a joint

Question 33

Define circumduction

Answer 33

When a limb moves in a circular fashion

Question 34

Define Supination

Answer 34

When the forearm is rotated, turning the hand from palm down to palm up

Question 35

Define pronation

Answer 35

When the forearm is rotated while the palm of the hand faces down

Question 36

Define Dorsiflexion

Answer 36

Occurs at the ankle when the toes are pointing towards the tibia and generally higher than the heel

Question 37

Define Plantarflexion

Answer 37

Occurs at the ankle when the toes are pointed downwards and the heel is raised

Question 38

Define Inversion

Answer 38

Occurs when the sole of the foot is turned inwards towards the imaginary midline of the body

Question 39

Define Eversion

Answer 39

Occurs when the sole of the foot is turned outwards from the imaginary midline of the body
