Biomechanics lecture 1

Question 1

Weight bearing

Answer 1

Straight and vertical bones

Question 2

Propulsion

Answer 2

Angulated bones, compressed joints and a flexible spine

Question 3

Kinetics

Answer 3

Study of the action of forces associated with motion

Question 4

Kinematics

Answer 4

The appearance of movement

Question 5

Abduction

Answer 5

Movement away from midline body

Question 6

Adduction

Answer 6

Movement towards midline body

Question 7

When walking forelegs forward

Answer 7

Stance phase retraction, swing phase protection

Question 8

When walking forelegs backing up

Answer 8

Stance phase protraction, swing phase retraction

Question 9

Lateroflexion

Answer 9

Bending of the spine

Question 10

Speed

Answer 10

When speed increases the stride, length is correlated with the strength and frequency

Question 11

Increase of speed

Answer 11

The amplitude of the steps become larger and the duration of the limb cycle is reduced

Question 12

Three main types of joints

Answer 12

• Fibrous
• Cartilaginous
• Synovial

Question 13

Fibrous

Answer 13

No movement in these joints

Question 14

Cartilaginous

Answer 14

• Connected by cartilage

- Little movement

Question 15

Synovial

Answer 15

Ball and socket joint and hinge joints

Question 16

Cartilage

Answer 16

• Spread load, decreases friction

- Invisible at radiographs

Question 17

Synovial fluid

Answer 17

-Lubricant for the joint and nutrition for cartilage made in the synovial membrane

Question 18

The distal limb

Answer 18

• Fetlock joint is hinge joint

- The joint surfaces of pastern and coffin allows sideway movement

Question 19

Postional tendons

Answer 19

Keeo muscles and bones in position

Question 20

Elactic tendons

Answer 20

Important for the movement
