Muscle names

Question 1

What are Parallel muscle arrangement

Answer 1

Fibres arranged vertically - smaller CSA, greater shortening

Question 2

What are Pennate muscle arrangement

Answer 2

Fibres arranged obliquely - Greater CSA, lesser shortening

Question 3

Concentric

Answer 3

Tension is greater than the load, muscle shortens, change in joint position and angle decreases

Question 4

Eccentric

Answer 4

Tension is lesser than load, Muscle elongates, change in joint position

Question 5

Isometric

Answer 5

Tension does not outweigh load, No change in joint position

Question 6

Agonist

Answer 6

Acts concentrically to create movement

Question 7

Antagonist

Answer 7

Acts eccentrically to oppose and control the movement

Question 8

Stabilisers

Answer 8

Prevents movement of joint

Question 9

Neutralisers

Answer 9

Eliminates an unwanted movement caused by another muscle

Question 10

Quadriceps femoris origin and insertion

Answer 21

Origin = Rectus femoris - illium, vastus medialis, intermedius and lateralis = femur
Insertion = tibial tuberosity

Question 22

Hamstring movement

Answer 22

hip = extension
Knee = Flexion + rotation
