Q

Clavipectoral fascia

A

encloses the subclavius and pectoralis minor

16
Q

Costocoracoid membrane

A

Part of the fascia between the pectoralis minor and the subclavius

17
Q

Suspensory ligament of axilla

A

part of clavipectoral fascia, inferior to the pectoralis minor
-supports the axillary fascia and pulls it and the skin inferior to it, upward during abduction…forming the axillary fossa

18
Q

Deltoid fascia

A

Invests deltoid and continuous with the pectoral fascia

19
Q

Brachial fascia

A

Covers arm like sleeve continuous superiorly with deltoid, pectoral, axillary and infraspinous fascia

20
Q

Medial and lateral intermuscular septa

A

Extend from deep surface of brachial fascia and attach to the central shaft and medial and lateral supraepicondylar ridges of the humerus

Divide arm into anterior(flexor) and posterior (extensor) comparments

21
Q

Antebrachial fascia

A

In forearm, seperated y the interosseous membrane connecting the radius and the ulna

22
Q

Extensor retinaculum

Flexor retinaculum

A
  • transverse bangs which holds the extensor tendons in position
  • continuation of antebrachial fascia
23
Q

Supplies skin on medial side

31
Q

Medial cutaneous nerve of the forearm

A

(C8, T1)
From medial cord of brachial plexus
Supplies skin on the anterior and medial surfaces of the forearm

32
Q

Perforating Veins

A

Form communication between the superficial and deep veins

33
Q

Median Cubital Vein

A

Communicates with cephalic vein and passes the anterior aspect of the elbow and joins the basilic vein and continues to join the axillary vein

34
Q

Median antebrachial vein

A

Ascends in the middle of the anterior aspect of the forearm
