URR Upper Extrem Venous Anatomy Flashcards
flow of the deep veins of the arm?
-venules
-deep digital veins
-metacarpal veins
-deep venous arches
-radial/ulnar
-brachial veins
-axillary veins
-subclavian
-innominate
-SVC
-right atrium
calf and forearm veins are considered what? since they are 2 veins of the same name follow the same course as a single artery of the same name?
venae comitantes
what is the primary drainage system of the upper extrem?
superficial venous system
what converges into the radial and ulnar veins?
metacarpal veins
where are the radial veins what do they join?
-deep veins of the forearm
-originate from the dorsal metacarpal veins
-pair of veins that course adjacent to the radial artery along the lateral aspect of the forearm
-join with paired ulnar veins to form the brachial veins at the antecubital fossa; can be one or two brachial veins
-norm demonstrate non spontaneous flow but norm aug response
where are the ulnar veins what do they join?
-deep veins of forearm
-originate from the palmar arch
-pari of veins that course adjacent to the ulnar artery along the medial aspect of the forearm
-joing with the paired radial veins to form the brachial veins at the antecubital fossa
-normally demonstrate non spontaneous flow but norm augment response
where do brachial veins course?
-may have 1 or 2 veins
-deep veins of the prox arm
-brachial veins course through anterior upper arm to meet the medial basilic vein at the axilla to become the axillary vein
-spontaneous flow w/ respiratory
where is the axillary vein? forms what? empties into what?
-deep vein
-segment formed from the brachial/basilic junction
-joins the cephalic vein to form the subclavian vein adjacent to lateral aspect of the clavicle
-empties blood into the subclavian vein
-spontaneous flow w/ respiratory phasicity
where is the subclavian vein? formed by? how is flow during expiration and inspiration?
-deep vein
-formed by axillary and cephalic junction
-located deep to the clavicle, usually courses somewhat parallel to clavicle
-ends when IJV merges w/ it to form the innominate vein
-spontaneous flow w/ respiratory phasicity AND pulsatile due to proximity to the heart
-flow increases w/ inspiration and decreases w/ expiration
what forms the IJV? receives blood from where?
-formed by the union of inferior petrosal and sigmoid dural venous sinuses in the brain
-receives tributaries from the face and neck and descends into the thorax, usually btwn the heads of the sternoscleidomastoid muscle
-the brachiocephalic vein (right and left) merge to form the SVC
-the SVC and IVC both enter the rt atrium of the heart
what kind of vein is the basilic vein?
-superficial vein until it reaches the prox arm and penetrates the deep fascia
-considered superficial vein in the forearm and deep vein in the prox arm due to its location in reference to the fascia
-originates from the dorsal arch, medially in wrist, adjacent to ulnar bone, courses superiorly along the medial arm to join the brachial vein in axilla
-axillary vein formed by the junction of the basilic and brachial veins just distal to the axilla
where does the cephalic vein originate, joins what?
-superficial vein
-originates from the dorsal venous arch laterally in wrist, adjacent to radial bone
-courses superiorly along the lateral aspect of the arm
-joins axillary vein at shoulder to form the subclavian vein
most common upper extrem vein used for arterial bypass?
cephalic
what is the antecubital vein?
-AKA median cubital vein
-superficial vein
-connects cephalic and basilic veins in antecubital fossa
-commonly used to draw blood
