Answer 12

Supports the knee joint

Question 13

What is the tensor fascia latae?

Answer 13

The muscular part of the fascia lata

Question 14

Spinal nerve roots of the sciatic nerve?

Answer 14

L4-S3

Question 15

Where does the sciatic nerve form?

Answer 15

The limbo-sacral plexus of the pelvis

Question 16

What is the course of the sciatic nerve from where it is formed in the (limbo)-sacral plexus?

Answer 16

Emerges in the middle of the gluteal region then descends and leaves the region to enter the posterior compartment of the thigh
Its branches descend through the popliteal fossa and posterior and lateral compartments of the leg into the foot

Question 17

Answer 17

S2-S4

Question 18

Where does the pudendal nerve form?

Answer 18

in the sacral plexus within the pelvis

Question 19

Answer 19

Emerges in the middle of the gluteal region and supplies the muscles, skin and fascia of much of the perineum

Question 20

What is another name for the posterior cutaneous nerve of the thigh?

Answer 20

Posterior femoral cutaneous nerve

Question 21

what are the sacral nerve roots of the posterior cutaneous nerve of the thigh?

Answer 21

S1-S3

Question 22

Where is the posterior cutaneous nerve of the thigh formed?

Answer 22

In the sacral plexus

Question 23

What is the course of the posterior cutaneous nerve of the thigh from where it is formed in the sacral plexus and what does it supply?

Answer 23

Emerges into the middle of the gluteal region and supplies the skin over the posterior aspect of the thigh

Question 24

What type of nerve fibres does the posterior cutaneous nerve of the thigh contain?

Answer 24

Somatic nerve that contains sensory and sympathetic fibres

Question 25

What causes a trendelenburg gait?

Answer 25

Damage to gluteus medius, minimus or their nerve supply

Question 26

Where is CSF taken from during a lumbar puncture?

Why?

Answer 26

The subarachnoid space surrounding the spinal cord at the level of L3/4 (between iliac crests)
Spinal cord ends around L1/2 intervertebral disc level (therefore avoiding injury to the conus modullaris)

Question 27

Where should intragluteal injections be administered?

Why?

Answer 27

The upper outer (superolateral) quadrant of the buttock

To avoid injury to the sciatic nerve
