vastus lateralis
iliotibial band
rectus femoris
tensor fascia lata
vastus medialis

Answers:

quadriceps tendon

Comments:

Correct
That's right! This is the anterior view of the thigh. ‘A’ is the quadriceps tendon. All components of the quadriceps will involve in extension of knee!
Continue

14.4 Question 9

9) Identify B.

Choices:

quadriceps tendon
vastus lateralis
iliotibial band
rectus femoris
tensor fascia lata
vastus medialis

Answers:

vastus lateralis

Comments:

Correct
That's right! Vastus lateralis is labelled ‘B’. You can identify the lateral side through the IT band! Also the tendon of the muscle is higher up compare to that of the vastus medialis.
Continue

14.4 Question 10

10) Identify C.

Choices:

quadriceps tendon
vastus lateralis
iliotibial band
rectus femoris
tensor fascia lata
vastus medialis

Answers:

iliotibial band

Comments:

Correct
That's right! The iliotibial band (aka. IT band) is labelled ‘C’. It arises due to the lateral thickening of the fascia lata.
Continue

11) Identify D.

Choices:

quadriceps tendon
vastus lateralis
iliotibial band
rectus femoris
tensor fascia lata
vastus medialis

Answers:

rectus femoris

Comments:

Correct
That's right! The rectus femoris is the long straight muscle locates in the midline of thigh.
Continue

14.4 Question 12

12) Identify E.

Choices:

quadriceps tendon
vastus lateralis
iliotibial band
rectus femoris
tensor fascia lata
vastus medialis

Answers:

tensor fascia lata

Comments:

Correct
That's right! Tensor fascia lata is inserted into the IT band anteriorly. It involves with movement of hip joint but also stabilizes lateral aspect of extended knee.
Continue

14.4 Question 13

13) Identify F.

Choices:

quadriceps tendon
vastus lateralis
iliotibial band
rectus femoris
tensor fascia lata
vastus medialis

Answers:

vastus medialis

Comments:

Correct
That's right! The muscle labelled ‘F’ is vastus medialis.
Continue

14.4 Question 14

14) Identify A.

Choices:

hamstring muscles
gluteus maximus
iliotibial band
biceps femoris

Answers:

hamstring muscles

Comments:

Correct
That's right! Hamstring muscles are located in the posterior compartment of thigh therefore flexes knee.
Continue

14.4 Question 15

15) Identify B.

Choices:

hamstring muscles
gluteus maximus
iliotibial band
biceps femoris

Answers:

gluteus maximus

Comments:

Correct
That's right! Gluteus maximus is labelled ‘B’. This muscle inserts into the IT band and therefore contribute to stabilization of lateral aspect of the extended knee.
Continue

14.4 Question 16

16) Identify C.

Choices:

hamstring muscles
gluteus maximus
iliotibial band
biceps femoris

Answers:

iliotibial band

Comments:

Correct
That's right! Iliotibial band is labelled ‘C’.
Continue

14.4 Question 17

17) Identify D.

Choices:

hamstring muscles
gluteus maximus
iliotibial band
biceps femoris

Answers:

biceps femoris

Comments:

Correct
That's right! ’D’ indicates the biceps femoris. As a muscle in the posterior compartment of thigh, it is a flexor of knee joint.
Continue

Correct

That's right! Trapezius’ origin spans from the occipital bone to the thoracic region of vertebral column. All muscle fibres insert onto the scapular spine. Its fibres orientation allows this muscle to participates in different movements.

Continue

That's right! Deltoid has a U-shaped origin spanning along lateral clavicle, acromion process to scapular spine. This abductor muscle can also be identified by its triangular shape.

That's right! Serratus anterior’s origin is like the edge of a serrated knife. The muscle attach to the anterior aspect of the medial border of scapula. Contraction of muscle causes abduction of GH joint and protraction of scapula.

That's right! Subscapularis arise from subscapular fossa on the anterior aspect of scapula. Its tendon horizontally crosses the anterior aspect of GH joint and therefore medial rotates humerus when contracts.

That's right! Supraspinatus arise from the supraspinus fossa, superior to the scapular spine. Supraspinatus pulls over superior aspect of GH joint and is therefore important for initiating abduction!

That's right! Teres minor joins infraspinatus thereby creates a common tendon that horizontally crosses the posterior aspect of the humerus. Contraction of these muscle = lateral rotation.

That's right! A bursa is a sac composed of synovial membrane that contains a minimal amount of synovial fluid. It functions to decrease friction between structures that move relative to each other.

That's right! Vastus lateralis is labelled ‘B’. You can identify the lateral side through the IT band! Also the tendon of the muscle is higher up compare to that of the vastus medialis.
