Answer 1

Phalanges, metacarpals, carpals, ulna, radius, humerus, clavicle, cranium, scapula, sternum, rib cage, vertebrae, pelvis, femur, patella, fibula, tibia, phalanges, talus, tarsals, meta carsals

Question 2

What are the 7functions of the skeleton

Answer 2

Protection, support, movement, shape, muscle attachment, mineral storage, blood cell production

Question 3

Long bones

Answer 3

Femur, humerus, tibia, fibula, metatarsals, phalanges, radius, ulna, metacarpals and phalanges

Question 4

Flat bones

Answer 4

Scapula, clavicle, rib cage, cranium

Question 5

Short bones

Answer 5

Carpals, talus, patella, tarsals

Question 6

Ball and socket

Answer 6

The round part of one bone fits into the cup like end of another
Largest range of motion
Eg hip shoulder

Question 7

Hinge

Answer 7

The convex surface of one bone fits into the concave surface of another
Elbow, ankle, knee

Question 8

Condyloid joint

Answer 8

Similar to ball and socket but the curved surfaces one much flatter
Wrist -> Flexion, extension

Question 9

Medial rotation

Answer 9

Bringing something to the middle - ball&socket
Eg tennis forehand

Question 10

Lateral rotation

Answer 10

Taking something away from the midline
Eg tennis backhand

Question 11

Horizontal Flexion

Answer 11

Flexion forwards

Question 12

Horizontal extension

Answer 12

Flexion backwards

Question 13

Agonist

Answer 13

The muscle responsible for the movement at a joint -> contracts + gets smaller
Eg the biceps brachii during Flexion of the elbow

Question 14

Antagonist

Answer 14

The muscle that lengthens or relaxes as agonist contracts
It has an action opposite to that of agonist
Eg the triceps brachii during Flexion at the elbow

Question 15

Describe Flexion at the shoulder and give an example

Answer 15

Agonist - anterior deltoid
Antagonist - posterior deltoid
Eg throwing your arms forward to dive in swimming

Question 16

Describe extension at the shoulder and give an example

Answer 16

Agonist - posterior deltoid
Antagonist - anterior deltoid
Eg receiving a relay baton

Question 17

Describe adduction at the shoulder and give an example

Answer 17

Agonist - latismus Dorsi
Antagonist - medial deltoid
Eg swimming breastroke bringing the arms back to your midline

Question 18

Describe abduction at the shoulder and give an example

Answer 18

Agonist - medial deltoid
Antagonist - latisimus dorsi
Eg preparing to throw a discuss

Question 19

Describe lateral Flexion and medial Flexion at the shoulder and give an example

Answer 19

Agonist - rotator cuff group
Antagonist - rotator cuff group
Eg backhand in tennis (lateral), forehand stroke with racket in tennis (medial)

Question 20

Describe Horizontal Flexion at the shoulder and give an example

Answer 20

Agonist - Pectorals major
Antagonist - teres minor
Eg forehand in tennis

Question 21

Describe Horizontal extension at the shoulder and give an example

Answer 21

Agonist - teres minor
Antagonist - pectorals major
Eg preparing to throw a discuss

Question 22

Describe circumdiction at the shoulder and give an example

Answer 22

Agonist & antagonist - rotator cuff group
Eg bowl in cricket
