UNE anatomy test 1
Terms in this set (40)
Internal thoracic artery, intercosgtal arteries, thoracoacromial trunk, lateral thoracic artery
Blood supply of the breast?
Lower edge of Teres major as continuation of axillary artery
Where does the brachial artery begin?
Profunda brachii artery
Which artery does the brachial artery gives rise to?
Superficial on medial aspect or farm.
Where is the brachial artery?
Where does the brachial artery divide at the neck of the radius into the ulnar and radial arteries?
Suprasacpulary (from subclavian), dorsal scapular, circumflex scapular (subscapular artery from axillary), possible intercostal arteries (aorta)
Which arteries make up the scapular anastomoses?
Arteries that turn around. Happens posterior and anteriorly.
What is a recurrent artery?
With radial and ulnar recurrent arteries.
Anterior and posterior arteries of the brachial and deep brachii anastomoses where?
BLood flow regardless of the position of the joint will continue. ALSO IF BLOOD FLOW is compromises by vascular stenosis, the blood flow to distal extremity is maintained. BLood flows through adjacent arteries.
What is the significance of anastomoses?
Which artery is superficial, has recurrent arteries, has many muscular branches, lateral to the FCR (flexor carpi radialis) at the wrist, superficial palmar artery (superficial palmar arterial arch)
WHich artery passes between the flexor digitorum superficialis (FDS) and flexor digitorum profoundus (FDP), has an ulnar recurrent artery, common interosseus (ant and post) artery, and is lateral to the FCU (flexor carpi ulnaris) at the wrist?
Flexor pollicis longus, flexor digitorum produndus, Pronator graduates
What does the anterior interosseuous artery supply?
Muscles of the posterior compartment, connects with anterior interosseuous artery via connection through a foramen in the interosseuous membrane,
What does the posterior interosseuous artery supply?
Cephalic vein (lateral)
Which vein goes into the anatomical snuff box?
Basilic vein (medial)
Which vein goes into the pinky through 2nd fingers?
Dorsal venous network.
What is between the cephalic and basilic veins?
Where does the cephalic vein empty into?
Delto pectoral triangle
Where does the cephalic vein enter to after it leaves the hand, into the upper arm?
Joins 2 companion veins of the brachial artery to form the axillary vein near the lower border o the Teres major muscle.
Which vein does the basilic vein form after it leaves the hand to go up?
It lies over the bicipital aponeurosis, which is a barrier protecting the deeper structures during venipuncture
The cubital vein is a connection junction between the basilic vein and cephalic vein, and it's where people draw blood
What is the significance of the median cubital vein?
Median cubital vein
What is the junction of the cephalic vein and basilic vein?
Line between medial and lateral epicondyles
What is the proximal boundary of the cubital fossa?
What is the lateral border of the cubital fossa?
What is the. Medial border of the cubital fossa?
Skin, fascia, and bicipital aponeurosis
What is the roof of the cubital fossa?
Biceps brachii TENDON
Brachial ARTERY, median NERVE
Deeper structures: radial N, it's deep branch and the beginning of ulnar and radial arteries. Not technically within cubital fosssa though
What is inside the cubital fossa?
Lateral to tendon of flexor carpi ulnaris
Where is the ulnar pulse?
Lymph node --> lymphoid tissue containing lymphocyte and macrophages --> heart
Capillary bed --> interstitial fluid leak --> lymphatic capillaries --> lymph vessel carries lymph to --->
Lymphatic vessels generally follow...._____ vessels
Major changels drain lymph back into the _______ system
The left side: thoracic duct --> left bracomediastinal trunk --> left jugular trunk
Left brachiocephalic vein
Where does 3/4 of the lymph drain into?
The right bronco mediastinal trunk --> Right subclavian trunk --> right jugular
Where does 1/4 of the lymph drain into?
- Pectoral (anterior)
- subscapular (posterior)
- lateral set along axillary vein
- central set (collecting from post/ant group, lateral)
- Intraclavicular: drains from lateral
-Apical: highest one. Gathering from lateral central
- para sternal: collect most medial part of breast.
Axillary lymph nodes: where are they, and about how many?
Lateral breast, anterolateral abdominal wall
Where does the pectoral/anterior node gets drainage from?
Located on subscapular muscle. Gets drainage from superficial back --> iliac crest.
Where does the subscapular/posterior nodes get drainage from?
Drains upper limb. Located along axillary vein
Where does the lateral node get drainage from?
Posterior, anterior, and lateral. Located in axillary.
Where does the central node get drainage from?
Vessels follow cephalic veins, empty into infraclavicular nodes which then drain into apical nodes of axilla
Where does the lateral side of the lymphatics empty into?
Lateral group of axillary nodes or to the cubital (supratrochlear) nodes before draining in the lateral group of notes.
Where does the medial side of the hand and forearm drain into?
Drains from lateral upper limb.
Where does the apical get drainage from?
