16
Q

What is the medial inter muscular septum of the brachium?

A

Extends from deep surface of brachial fascia to the humerus, distally to the medial supraepicondylar ridge
In conjunction with the lateral intermuscular septum separates the brachium into anterior and posterior compartments

17
Q

What is the lateral intermuscular septum of the brachium?

A

Extends from the deep surface of brachial fascia to the humerus distally to the lateral supraepicondylar ridge

18
Q

What is antebrachial fascia?

A

Continuous superiorly with brachial fascia, utilizes the interosseous membrane to divide the antebrachium into an anterior and posterior compartment
Includes extensor retinaculum, palmar carpal L and flexor retinaculum

19
Q

What is the extensor retinaculum of the antebrachium?

A

Transverse focal thickening of antebrachial fascia
Holds the extensor tendons in position
6 synovial tendon sheaths surround the long extensor tendons of the forearm as they pass under the extensor retinaculum to reduce friction

20
Q

What is the palmar carpal L of the antebrachium?

A

Corresponding anterior transverse focal thickening of the antebrachial fascia
Continuous with the extensor retinaculum

21
Q

What is the flexor retinaculum of the antebrachium?

A

Transverse carpal L
Deep and distal to the palmar carpal L
Fibrous band extending from the tubercles of the scaphoid and trapezium across the carpal arch to the hook of the hamate and pisiform forming the carpal tunnel

22
Q

What is palmar fascia of the hand?

A

Continuous proximally with the antebrachial fascia

Associated with palmar aponeurosis

23
Q

Describe the palmar aponeurosis

A

Thickened central region of palmar fascia
Continuous proximally with the palmaris longus T
Includes superficial transverse metacarpal L, retinacula cutis, medial fibrous septum and lateral fibrous septum

24
Q

What separates the hypothenar compartment from the central compartment?

A

Medial fibrous septum

25
Q

What separates the thenar compartment from the central compartment?

A

Lateral fibrous septum

26
Q

What restricts palmar skin movement?

A

Retinacula cutis of palmar aponeurosis

27
Q

What is dupuytren contracture?

A

A disease resulting in the shortening, thickening and fibrosis of the palmar aponeurosis and palmar fascia which results in a partial flexion of the 4th and 5th digits

28
Q

What is dorsal fascia of the hand?

A

Deep to subcutaneous fat on the dorsum of the hand

29
Q

What are fibrous digital sheaths of the hand?

A

Distal extensions from the palmar aponeurosis
Fibrous tubes that enclose the synovial sheaths of the long flexor tendons
Arranged into altering annular and cruciform segments
Associated digital synovial sheaths

30
Q

What is the hypothenar compartment of the hand?

A

Contains the hypothenar muscles

31
Q

What is the central compartment of the hand?

A

Contains the flexor tendons, the lumbrical muscles, superficial palmar arterial arch, digital vessels and nerves

32
Q

What is the thenar compartment of the hand?

A

Contains the thenar muscles

33
Q

What is the adductor compartment of the hand?

A

Contains the adductor pollicis <

34
Q

What is the interosseous compartment of the hand?

A

Between the metacarpal bones

Contains the interossei muscles

35
Q

What can irritation of the synovial sheaths of the antebrachium cause?

A

An accumulation of mucopolysaccharide fluid that can form a usually painless lump known as a synovial or ganglion cyst

36
Q

Infections of the synovial sheath of the antebrachium can cause what?

A

Swelling in very specific and characteristics configurations that follow the shapes of these sheaths
