1. Look at another Q1 from Jan 2010 Tackle this easier question by picking out the correct answer from the choices below.

Hinge-- Flexion-- Triceps Brachii

Hinge-- Extension-- Triceps Brachii

Hinge-- Flexion-- Trapezius

Classic antagonistic pair

Brachii = of the arm

Explanation

Classic antagonistic pair

Brachii = of the arm

2. These are the hamstrings: semimembranosus, semitendinosus and Biceps Femoris . They are the agonists of knee flexion Is all of this TRUE or FALSE

True

False

The statement is true. The hamstrings, which consist of the semimembranosus, semitendinosus, and Biceps Femoris muscles, are indeed the agonists of knee flexion. This means that they are primarily responsible for bending the knee joint.

3. TRUE/ FALSE? The main agonist of the movement taking place at the hip is Gluteus Maximus (Click the link to see the movement) https://www.exrx.net/AnimatedEx/HipFlexors/CBLyingLegRaise.gif

True

False

It's hip flexion, therefore Iliopsoas

Explanation

It's hip flexion, therefore Iliopsoas

5. Here is a supplementary question that also refers to the picture of the gymnast:.

Pick out the Rotator cuff muscles from the alternatives below.

Teres Minor

Sacrospinalis

Teres Magnus

Semispinalis

Subscapularis

The rotator cuff muscles are a group of muscles that help stabilize and move the shoulder joint. The teres minor and subscapularis are both part of the rotator cuff muscles. The teres minor is a small muscle located on the back of the shoulder, while the subscapularis is a larger muscle located on the front of the shoulder. These muscles work together with the other rotator cuff muscles to provide stability and control during shoulder movements.

6. Here you can see the Quadriceps group of muscles. Pick out the only correct statement below.

Quads extend (straighten) the knee, as when kicking a ball or pushing off starting blocks.

Explanation

Quads extend (straighten) the knee, as when kicking a ball or pushing off starting blocks.

7. Below is an image from the Jan 2011 paper. Choose the three correct answers form the list of possibilities

Hinge

Ball and socket

Iliopsoas

Gluteus Maximus

Extension

Flexion

The ball and socket joint allows for a wide range of movement in multiple directions, making it one of the correct answers. The iliopsoas is a muscle group that is responsible for flexing the hip joint, which is another correct answer. Flexion refers to the bending of a joint, so it is also a correct answer in this context. The other options, hinge, gluteus maximus, and extension, are not relevant to the given question and are therefore incorrect.

9. Look at the ankle position shown in the picture. Say which muscle is the agonist of this ankle movement and click on the movement being shown

Plantarflexion

Dorsiflexion

Gastrocnemius

Tibialis Anterior

Flexion

Remember the P: Plantarflexion = Pointing the toes
Soleus is another correct answer

Explanation

10. Look at this Question 1 from May 2009 Only one set of answers is correct. Choose the correct one.

Hinge-- Biceps Femoris-- Rectus Femoris-- Eccentric-- Type 2b

Hinge-- Rectus Femoris-- Vastus Lateralis-- Concentric--Type 2b

Hinge-- Rectus Femoris-- Biceps Femoris-- Eccentric--Type 2b

Hinge-- Rectus Femoris-- Biceps Femoris-- Concentric--Type 2b

The player is jumping- this will always be concentric work

Explanation

11. Pick out the 1 FALSE statement in this information about movement at the SHOULDER JOINT

A person with their arm by their side has their shoulder extended

Anterior Deltoid is on the front of the body

Middle Deltoid is the muscle of shoulder abduction

A tennis forehand would usually be an example of horizontal flexion

A butterfly swimmer would be performing circumduction in their arm action

Lifting your arm forwards and upwards is shoulder flexion

The bones articulating at the shoulder are humerus and clavicle

Latissimus Dorsi moves the humerus downwards

PectoralisMajor helps to pull your arms across your chest

The shoulder is the joint with most movement possibilities

Make sure you know all agonists: F/E, Ab/Ad, HF/Hex

Explanation

The shoulder is the joint with most movement possibilities

Make sure you know all agonists: F/E, Ab/Ad, HF/Hex

12. These statements about the hip are TRUE or FALSE. Select the TRUE statements.

There are 3 adductor muscles: adductor longus, magnus and brevis

Iliopsoas is the muscle of hip extension

The only movements possible at the hip are: Flexion, Extension, adduction, Abduction and Rotation

Gluteus Medius is the agonist of hip abduction

When you bring your knees up to perform a tuck jump you will be performing hip flexion

Hip extension involves bending at the hip

Gluteus Maximus is the agonist of hip extension

The statement "There are 3 adductor muscles: adductor longus, magnus and brevis" is true because these three muscles are indeed adductor muscles of the hip. The statement "Gluteus Medius is the agonist of hip abduction" is true because the gluteus medius muscle is responsible for the abduction of the hip. The statement "When you bring your knees up to perform a tuck jump you will be performing hip flexion" is true because bringing the knees up towards the chest involves hip flexion. The statement "Gluteus Maximus is the agonist of hip extension" is true because the gluteus maximus muscle is the primary muscle responsible for extending the hip.
