Fascia : match fascia and what it covers
- Pectoral fascia
- Axillary Fascia
- Calvipectoral Fascia
- Deltoid Fascia
- Costocoracoid Membrane
- pectoralis maj M
- axilla
- pectoralis min M
- deltiod M.
- subclavius M.
Fascia: match which fascia covers what
- Brachial Fascia
- Antebrachial Fascia
- Musculature of brachium
- musculature of antebrachium
what are the layers of fascia starting from the skin (4)?
Skin
Fatty superficial fascia
deep superficial fascia
(brachial) fascia
What deep fascias keep the brachii (biceps/triceps) separate from eachother ant/post (2)?
Lateral intermuscular septum
Medial intermuscular septum (on either sides of the humerus)
what is in the antebrachium that keeps the anterior muscle (flex) for the posterior (extensor musc)?
interosseous membrane (syndesmosis) between ulna and radius
What is the difference between the flexor retinaculum (transverse carpal L.) and palmar capral L./extensor retinaculum in the wrist?
Palmar capral L & extensor retinaculum (keeps tendons down) are made of antebrachial fascia, and are focal thickening of deep fascia, while flexor retinaculum an actual ligament deeper down
What is palmar aponeurosis and retinacula cutis in the hand?
Palmar aponeurosis is a focal thickening of skin, commonly a sheet of tendon to strengthen
Retinacula Cutis goes through aponeurosis to strengthen the skin to keep it in place so it is not like our dorsal hand skin
