General Anatomy Questions

Question 1

3 muscles attaching to coracoid process

Answer 1

Short head of biceps tendon, coracobrachialis, pec. minor

Question 2

What nerve innervates anterior muscle of the arm?

Answer 2

Msc

Question 3

Think of anterior forearms muscles as 2 and 2 halves of muslces

Answer 3

Biceps brachii, coracobrachialis (as uppper half) and brachialis (as lower half) which originates from coracobrachialis’s location of insertion

Question 4

What structure is found in the roof of the carpal tunnel?

Answer 4

FCR, R FOR ROOF

Question 5

Medial pectoral nerve, M for more, hence it innervates

Answer 5

Both pec. maj. & min.

Question 6

Lateral pectoral nerve, L for less, hence it innervates

Answer 6

Pec. maj ONLY

Question 7

What mnemonic for superficial layer of anterior muscles of forearm

Answer 7

PFPF, Pronator teres, FCR, Palmaris longus, FCU

Question 8

Anterior forearm muscles are all innervated by median nerve except for

Answer 8

FCU (ulnar nerve), FDP (ulnar nerve supplies medial half)

Question 9

What’s unique about FDP

Answer 9

Median nerve supplies lateral half, ulnar nerve supplies medial half

Question 10

Long head of biceps tendon has its origin at the supraglenoid tubercle, for long head of triceps, this means that it would have its origin at

Answer 10

The infraglenoid tubercle as the opposite of biceps is triceps

Question 11

What forms roof of carpal tunnel? How many tendons and what structures go through the carpal tunnel? What structure attach to carpal tunnel?

Answer 11

Flexor retinaculum forms roof

9 tendons, FDS (x4), FDP (x4), FPL (x1), median nerve, synovial sheaths

Scaphoid & trapezium tubercles (laterally), hook of hamate & pisiform (medially)

Question 12

Whats interesting about the way FDS inserts

Answer 12

It splits into 4 tendons where each tendon is split into half so that FDP can go in between it. FDS inserts onto middle phalanx and FDP inserts into distal phalanx.

Question 13

Mnemonic for rotator cuff muscles

Answer 13

Sub Supra Infra Teres

Insertions are lesser tubercle (humerus), sup. greater, mid. greater, inf. greater

Question 14

Teres major rotates arm ___ so teres minor rotates arm___

Answer 14

Medially/internally, laterally/externally

Question 15

What action is the biceps brachii known for

Answer 15

Corkscrew, supinate while putting hand on cork and abduct when taking it out

Question 16

Deep layer of forearm muscles attach distally

Answer 16

Hence FDP and FPL attach to distal phalanx

Question 17

Which area do you test for axillary nerve?

Answer 17

Regimental badge

Question 18

What can be used to identify proximal end of the carpal tunnel?

Answer 18

Distal crease of wrist

Question 19

Anatomical snuffbox

• What goes through it?
• Boundaries?
• Roof?
• Floor?

Answer 19

• Radial artery
• Boundaries: ant (APL & EPB), post (EPL)
• Roof: Cephalic vein, superficial branch of radial nerve
• Floor: scaphoid and trapezium

Question 20

Motions in each plane

• Sagittal
• Coronal
• Transverse

Answer 20

Sagittal - F/E
Coronal - Sideways
Transverse - Rotation

Question 21

Describe the area the cubital fossa is located in

Answer 21

Medially: PT
Laterally: brachioradialis
Roof: bicipital aponeurosis
Floor: brachialis

Contents: median cubital vein, cutaneous nerves, brachial artery (ulnar and radial arteries), median and radial nerves - often but not always part of cubital fossa contents as it is in the vicinity of it (laterally).

Question 22

Muscles attachment of bicipital groove

Answer 22

Laterally: Pec Maj
Medially: T Maj
Floor: Lat Dorsi

Question 23

Hand interossei muscles are innervated by

Answer 23

Ulnar nerve

Question 24

Adductor Policis - innervated by?

Answer 24

Ulnar nerve

Question 25

What movement is a combination of the three planes?

Answer 25

Circumduction

Question 26

How are cords of brachial plexus named?

Answer 26

According to their relation to axillary artery e.g. Lateral, Posterior, Medial

Question 27

Their location relative to clavicle

• Roots and trunks
• Divisions
• Cords and terminal branches

Answer 27

Roots and trunks: SUPRA
Divisions: BEHIND
Cords and terminal branches: INFRA

Question 28

Pes anserinus aka goose foot

Answer 28

Conjoined tendons of three muscles that insert onto the anteromedial (front and inside) surface of the proximal extremity of the tibia. The muscles are the sartorius, gracilis and semitendinosus sometimes referred to as the guy ropes.

Question 29

Example of Primary Cartilangious Joint

Answer 29

Epiphyses of growing bones

Question 30

Trabeculae in femur is least dense at ____ hence leading to fractures

Answer 30

Surgical neck

Question 31

Reverse keystone effect

Answer 31

The sacrum sinks fowards and downwards into the pelvis. Post. lig. tighten and draw iliac bones together. Stability is therefore due to the ligs. (particularly the interosseous sacroiliac ligs.) - the bones (sacrum and ilium) tend to “open” the joint up.

Question 32

Strongest ligament in the body

Answer 32

Iliofemoral (‘Y’) lig. of Bigelow

Question 33

When referring to deficiencies in a joint, it means?

Answer 33

Ligaments are thin, not that bones are completely exposed in that area
