2) pulmonary stenosis, which is narrowing beneath or in the blood vessel leading to the lungs
3) overriding of the aorta, in which the aorta lies directly above the ventricular septal defect
4) as a result of these events, the right ventricle becomes thickened or hypertrophied.

A. anterior then medial to the brachial artery
B. medial then anterior to the brachial artery
C medial to the brachial artery

Ans C

Very Common Recall Question either about the median nerve or ulnar nerve relation
The median is lateral anterior then medial to the brachial artery
Ulnar nerve is ulnar to the brachial artery and behind the medial epicondyle, so the nerve is the guardian for the food
The radial is radial to the brachial artery and anterior to the lateral epicondyle
Ulnar nerve is ulnar to the ulnar artery
By the way remember the ring finger has sensory supply from the radial nerve it’s the finger that’s supplied by the whole 3 nerves may be this what made it the ring united name, if you got engaged looka t your ring and remember it

A

A Flexor digiti minimi brevis
B Flexor digitorum profundus
C Flexor digitorum superficialis
D Fourth palmar interosseous
E Lumbirical

Ans B

it’s funny to have the Flexor profundus cut without the superficialis
but the trick is that the litlle finger can have only the profundus in about 15 % of the population :D and there is no flexor digiti minimi muscle but there is extensor digiti minimi has it’s own compartment in the 5th extensor compartment

and remember there is a palmaris brevis which is in the hypothenar eminence supplied by the ulnar nerve

while the palmaris longus supplied by the median nerve and can be abscent in 10 % of the population and very commonly to be used as a tendon graft like the plantaris tendon muscle

A

A Median nerve
B Musculocutaneous nerve
C Posterior interosseous nerve
D Radial nerve
B. Ulnar nerve

Ans D

MID-INGUINAL POINT:
Halfway between the pubic symphysis and the anterior superior iliac spine.
The femoral artery crosses into the lower limb at this anatomical Landmark
INGUINAL LIGAMENT:
A fibrous band extending from the anterior superior iliac spine to the pubic tubercle.
Formed by the lower border of external oblique aponeurosis, which is thickened and folded on itself.

Femoral Artery:
. It is the contiuation of the external iliac artery at the mid inguinal point
. It descends in the femoral triangle
. Then, it continues in the adductor canal
. It reaches the adductor hiatus where it becomes the popliteal artery
. It supplies all structures in the thigh

B. Femoral nerve
C. Femoral vein
D. Inguinal ligament
E. Pectineal ligament

40
Q

45- 65 years old man presented with an inguino-scrotal swelling in the right groin which is non tender. A cough impulses is elicited, At operation, an indirect inguinal hernia is repaired. The cremasteric muscle is derived from which of the following

A

A. External oblique aponeurosise
B Internal oblique muscle
C. Rectus abdaminis muscle
D. Rectus sheath
E. Trsusversalis fascia

Ans B

the continuity of the abdominal layers with the inguinal canal and scrotal layers are a must trick

if you remembered the order of external internal and transversalis you can figure out the the layers

external fascia from ? external oblique

Internal Fascia from ? fascia transversalis

So where the middle cremastric be from ? of course from the internal oblique

Take them and continue to the scrotum

so they are always the same they are just expanding teratories
believe you know it and you will recall it

Coverings of the Spermatic Cord
They are three layers of fascia derived from the layers of the anterior abdominal wall. Each covering is acquired as the processus vaginalis descends into the scrotum through the layers of the abdominal wall.
1- External spermatic fascia derived from external oblique aponeurosis and attached to the margins of the superficial inguinal ring
2- Cremasteric fascia derived from the internal oblique muscle
3- Internal spermatic fascia derived from fascia transversalis and attached to the margins of the deep inguinal ring

A

A. Femoral nerve
B. Genitofemoral nerve
C Ilioinguinal nerve
D Lateral cutaneous nerve
E Sciatic nerve

Ans A

Injury to the nerves after inguinal hernia surgery is uncommon. The femoral nerve may be damaged by suture or staples, tissue scar entrapment, local anesthesia blockade or direct compression. We present a case of a transient lesion of the femoral nerve after mesh hernioplasty for a re-recurrent inguinal hernia, confirmed by radiological studies, electrophysiology and clinical recovery. The diagnosis, mechanism of injury and surgical approach are reviewed. Surgery to a recurrent hernia may be underestimated. The role of electromyography nerve conducting studies is emphasized insisting on the importance of clinical evolution for the successful management of these infrequent injuries.

18- A 65-year-old man has a history of transient ischemic attacks. He is due to undergo carotid
endarterectomy. Which one of the following is true of the internal carotid artery?

A

A. Begins at the level of the sixth cervical vertebra ter
B. Divides into the anterior, middle and posterior cerebral arteries
C. Gives off the ophthalmic artery
D. Is accompanied within the skull by preganglionic sympathetic nerves
E. Passes through the foramen ovale

Ans C

C4 is the Common carotid Bifurcation

the preganglionic cells of the sympathetic nervous system are located between the first thoracic segment and third lumbar segments of the spinal cord

The carotid canal is a passage within the petrous temporal bone and transmits the internal carotid artery and sympathetic plexus. Its inferior opening is called the carotid foramen and is situated anteriorly to the jugular fossa and medially to the carotid plate.

The two nerves that pass from the foramen lacerum are the greater petrosal nerve, which represents the pre-ganglionic parasympathetic fibers, and the deep petrosal nerve which, representing the post-ganglionic sympathetic fibers

So simply The internal carotid artery doesn’t pass through the foramen lacerum and not related to the preganglionic sympathetic nerves which already found in the foramen lacerum

A useful mnemonic to remember the branches of the internal carotid artery is:
. A VIP’S COMMA
Mnemonic
· A: anterior choroidal artery (C7)
