upper limb

Question 1

landmarks of pectoral girdle

Answer 1

• clavicle
• acromion
• ac joint
• coracoid process
• head of humorous
• lesser tubercle
• greater tubercle
• scapula
• glenoid cavity

Question 2

clavicle

Answer 2

sternal end: articulates with manubrium of sternum
acromial end: articulates with acromium at ac joint

Question 3

scapula

Answer 3

infra spinous fossa : larger than supraspinous fossa
supraspinous fossa : big plates of scapula
acromion
coracoid process
infraglenoid tubercle
supraglenoid tubercle

Question 4

humerous

Answer 4

Anterior Inferior landmarks: RCCT

Randy Corrects Caper Trying ME

Radial fossa, coronoid fossa, capitulum, trochea, medial epicondyle

posterior inferior landmarks : ME OTLE

Me & Ollie tip LE

medial epicondyle, olecranon fossa, trochea, lateral epicondyle

greater tubercle
lesser tuberle
inter tubercular sulcus (bicipital groove)
deltoid tuberosity
radial fossa : located above the capitulum
radial groove (for radial nerve, spiral groove)
coronoid fossa : located above the trochlea
capitulum : articulation with head of radius
medial epicondyle
lateral epicondyle
trochea: articulation with the throcheal notch of ulna
olecranon fossa

Question 5

axilla

Answer 5

• armpit
• wedged in between clavicle, humorous and 1st rib
• filled with blood vessels and nerves, no bones

Question 6

arteries (lecture 9)

Answer 6

• *arch of aorta**: behind sternum
• *Brachiocephalic trunk**: only on right side, only exists briefly, the become :
• *right and left common carotid arteries**
• *vertebral artery**: goes to supply head
• *subclavian artery**: passes behind/is protected by clavicle, passes by 1st rib and then becomes:
• *axillary artery :** has section 1,2 and 3. number corresponds to how many branches coming off them
• *brachial artery**: carries blood to arm, become radial and ulnar arteries

Question 7

deep veins of upper limb

Answer 7

• Exact mirror of the arteries
• Veins connecting blood that lost its oxygen and sends back to heart
• Have the same names as arteries
• Usually have two veins on each side of the arteries, sometimes 3

Question 8

superficial veins of upper limb

Answer 8

cephalic vein of arm : closer to thumb side (anatomical position)

basilic vein of arm: comes up inside of arm

both of these veins dump into the axillary

median cubital vein

cephalic vein of forearm

basilic vein of forearm

Question 9

superficial venous drainage

Answer 9

• just beneath the surface of skin
• channel blood from cutaneous tissues to deep veins via perforations in the deep fascia
• deep veins share routes with arteries, and many are enclosed in the same sheaths

Question 10

profunda brachi

Answer 10

• first and largest branch of the brachial artery
• deep artery of arm

Question 11

deep palmar arch vs superior palmar arch

Answer 11

deep palmar arch :

• formed by radial artery
• joined to a branch of the ulnar artery
• supplies deep muscles of hand, thumb and index finger

superior palmar arch :

-formed by ulnar artery

-joined to branch of radial artery
