Q

Autonomic innervation of the brachial plexus? what type of autonomic motor innervation? (PSNS or SNS)

Where are the preganglionic neurons?
Where do they synapse?
Where are post ganglionic axons?
What do they innervate?

A

Sympathetic ONLY (no parasympathetic)
Preganglionic neurons (T1-T6)
Synapse in paravertebral (cervical) ganglia
-Postganglionic axons accompany somatic nerves of the brachial plexus to innervate:
-sweat/sebaceous glands
-arrector pili muscles
- vasculature

Q

Where does lymph from deep veins and cubital lymph nodes drain?

A

Humeral (lateral) Axillary lymph nodes
drain into Central nodes and then drain into apical axillary lymph nodes then to supraclavicular nodes then into either the Right lymphatic duct or the Thoracic duct

16
Q

What forms the floor of the dectopectoral triangle? What vein goes through the dectopectoral groove?

A

Costocoracoid membrane forms the floor

Cephalic vein travels through the deltopectoral triangle

17
Q

What ligament is superficial to the Flexor retinaculum? What travels between the two ligaments?

A

Palmar carpal ligament

  • Superficial palmar branch of radial artery
  • Ulnar artery and Ulnar nerve
  • Tendon of palmaris longus is superficial to the flexor retinaculum also.
18
Q

Flow of lymph from cubital all the way back

A

Cubital> Humeral > central > apical > supraclavicular > RLD or TD

19
Q

What are the contents of the Deltopectoral groove and Triangle? 3 things

what forms the floor?

A
  1. Cephalic vein
  2. Thoracoacromial Artery
  3. Lateral Pectoral nerve
  4. Costocoracoid membrane (floor of triangle)
20
Q 
What are the boundaries of the Axilla?
Apex (what called) (what 3 structures)
base (what called) 
ant wall (what structure formed? what 4 structures)
post wall (structure and 4 borders)
med wall (2 borders)
lat wall (1 border)
A

APEX: cervico-axillary canal- (1st rib, clavicle, scapula)
BASE: axillary fossa- (axillary fascia, subcutaneous skin)

ANT WALL: (Pec major/minor- anterior axilary fold. Subclavius, clavicle)

POST WALL: (scapula, subscapularis, Lat dorsi, Teres Major, posterior axilary fold)

MED WALL: Thoracic wall, serratus anterior

LAT WALL: intertubercular sulcus

21
Q

What forms the anterior and posterior axillary folds

A

ant: pec major
post: teres major & Lat dorsi

22
Q

3 branches of the Axillary artery

What is the next distal branch of the brachial artery? What does it turn into as it runs distally?

A

1- superior thoracic artery

2- Thoracoacromial artery (CADS)
2- Lateral thoracic artery (w/ long thoracic Nerve)= SALT

3- Subscapular (ct- Circumflex scapular & thoracodorsal)
3- PCHA
3- ACHA

Profunda brachii artery> radial collateral> Radial recurrent

23
Q 
Axillary Vein
Landmark?
When does it become subclavian vein? why important?
What are the tributaries?
Where does it arise from and morph into?
A
  • Inferior border of teres MAJOR
  • subclavian vein at lateral border of 1st rib (CENTRAL LINE)
  • Tributaries- just like axillary arteries EXCEPT NO THORACOACROMIAL VEIN
  • Arises from brachial veins and dumps into basillic veins then forms the Axillary vein.
24
Q

Humeral (lateral) lymph nodes
Where located?
Where is lymph from ? Where is it NOT from?

A

Lateral wall of axilla- medial and posterior to axillary vein
- lymph from UE (except lymph from cephalic vein)

25
Q

Pectoral (anterior) lymph nodes
Where at?
Where lymph from?

A

Along lateral thoracic vessels

- lymph from anterior thoracic wall/ Breast

26
Q

Subscapular (posterior) lymph nodes?

location and where lymph from?

A

posterior axillary fold along subscapular vessels

lymph from posterior thoracic wall/ scapula

27
Q

Central lymph nodes

Where and what lymph from?

A

Deep to pectoralis minor

Lymph from humeral, pectoral, and subscapular nodes

28
Q

Apical lymph nodes
Where at?
Where lymph from?
Where does lymph drain into?

A

Apex of axilla
Lymph from central nodes and deltopectoral nodes

Drains into supraclavicular nodes

then drains either into Right lymphatic duct or the Thoracic duct
