Question 1

BUCK’S FASCIA

Answer 1

Bucks fascia is a layer of deep fascia that covers the penis it is continuous with the external spermatic fascia and the penile suspensory ligament. The membranous part of the urethra may partially pass through Bucks fascia as it passes into the penis. However, the spongiose part of the urethra is contained wholly within Bucks fascia.

Question 2

VERTEBRAL ARTERIES

Answer 2

Enter the cranial cavity via foramen magnum
Lie in the subarachnoid space
Ascend on anterior surface of medulla oblongata
Unite to form the basilar artery at the base of the pons

Branches:
Posterior spinal artery
Anterior spinal artery
Posterior inferior cerebellar artery

Question 3

FEMORAL ANGLE

Answer 3

The normal angle in males between the femoral head and shaft is 130o. Changes to this angle may occur as a result of disease or pathology and should be investigated.
Females have an angle that is around 110-120o

Question 4

PUDENDAL CANAL

Answer 4

The pudendal canal is located along the lateral wall of the ischioanal fossa at the inferior margin of the obturator internus muscle. It extends from the lesser sciatic foramen to the posterior margin of the urogenital diaphragm. It conveys the internal pudendal vessels and nerve.

Question 5

Trachea

Answer 5

Trachea
Location C6 vertebra to the upper border of T5 vertebra (bifurcation)

Question 6

ANTERIOR INTEROSSEOUS NERVE

Answer 6

Anterior interosseous lesions occur due to fracture, or rarely due to compression. The Gantzer muscle is an aberrant accessory of the flexor pollicis longus and is a risk factor for anterior interosseous nerve compression. Remember loss of pincer grip and normal sensation indicates an interosseous nerve lesion.

Question 7

ADDUCTOR CANAL

Answer 7

It contains the saphenous nerve, femoral vein and the superficial branch of the femoral artery.
