Upper Limb Vasculature and Transitional Areas Flashcards
Axilla artery is a continuation of _____
subclavian artery
the axillia artery lies between the ______ and the lower boarder of teres major muscle or pectoralis major muscle
first rib
Based on the position of the artery relative to the pectoralis minor muscle, axillary artery is divided into three different parts. These parts include:
- superior thoracic artery
2.a thoracoacromial and b. lateral thoracic artery
3a subscapular artery, anterior and posterior circumflex humeral arteries
The first part which lies before the muscle, has one branch which supplies the upper part of the thoracic cavity. It is called the
superior thoracic artery
the second part of the axilla artery gives off two branches.
the thoracoacromial and lateral thoracic artery
the ___________ supplies some parts of the pectoral and deltoid region
thoracoacromial
the _______ mainly supplies the lateral thoracic wall including the serratus anterior muscle
lateral thoracic artery
The third part of the axilla artery located after the pectoralis minor gives off branches. These branches include
- the subscapular branch
- the anterior circumflex humeral artery
- posterior circumflex humeral artery
the _____________ supplies the muscles of the scapular region
subscapular artery
the _________ and ___________ arteries turn around the surgical neck of the humerus anteriorly and posteriorly respectively. These arteries will supply those muscles attached to the proximal end of the humerus
- the anterior circumflex humeral artery
- posterior circumflex humeral artery
After passing the inferior border of teres major or pectoralis, the name of the axilla artery will change to ________ artery
Brachial
the brachial artery starts at the lower border of _______ or _________. Then it runs down the arm
lower border of teres major or pectoralis major.
The main branches of the brachial artery are as follows:
deep brachial
muscular brachial
the ____ artery moves posteriorly towards the radial groove to accompany the radial nerve. Here it supplies the posterior compartment of the arm.
Deep brachial
for the anterior compartment musculature
Muscular branches
Brachial A. ends in the distal part of the _________ by dividing into the ulnar and radial arteries.
cubital fossa
The larger of the two terminal branches of the brachial artery.
ulnar artery
Is smaller than the ulnar artery and supplies the lateral side of the forearm.
radial artery
The ulnar artery lies under __________ and is accompanied by ulnar nerve on its way
flexor carpi ulnaris
Ulnar: Its branches in the forearm are more numerous than the radial artery and supply the ______, muscles of the __________ on the medial side, the deep muscles of _______ compartment of forearm, the majority muscles of the ________ compartment and the ______ joint
Its branches in the forearm are more numerous than radial artery and supply the elbow, muscles of the anterior compartment on the medial side, the deep muscles of anterior compartment of forearm, the majority muscles of the posterior compartment and the wrist joint
ulnar: It passes distally over the anterior aspect of the wrist to the palm and takes part in forming the ________________
palmar arterial arches
The radial artery descends on the ________ side of the forearm under the cover of the brachioradialis muscle
lateral
The branches of this artery in the forearm will supply the ______, muscles of the anterior compartment on the lateral side, the muscles on the lateral side of the posterior compartment, and the wrist joint.
lateral
radial: In the distal part of the forearm, it passes through the ________ , after passing through the first interosseous space in hand, enters the palm of the hand and takes part in forming the ________ palmar arch
anatomical snuff box
deep palmar arch.
_________ is the major source of blood supply for the dorsal surface of the hand.
Radial artery
radial: The branches of this artery form a ____________ at the level of carpal bones
dorsal arterial arch
The other branches of the radial artery will join with terminal branches of the ulnar artery to form a ________ and a ______ palmar arterial arch. Arteries derived from these arches will supply the hand.
superficial and a deep palmar arterial arch
The venous system of the upper limb drains deoxygenated blood from the hand, forearm, and hand. It can anatomically be divided into the ________ veins and the ______ veins.
It can anatomically be divided into the superficial veins and the deep veins
vein on the radial side
cephalic vein
Cephalic on lateral THUMB - head
vein on the ulnar side
basilic vein
Bascilic on medial ULNAR - basement
the three areas of transition
- axilla
- cubital fossa
- carpal tunnel
is a four-sided pyramidal space situated between the upper part of the arm and the chest wall.
axilla or armpit
This space is a transition region between the root of the neck and the upper limb and most of the structures that enter or leave the upper limb pass through this space.
axilla
name the axilla 4 walls
√ Anterior wall
√ Posterior
√ Medial wall
√ Lateral wall
….. wall is formed by the pectoral region
√ Anterior wall
….. wall is formed by the scapular region
√ Posterior wall
…..wall is formed by the upper 4 ribs and the upper part of the serratus anterior muscle that attaches to these ribs.
√ Medial wall
…..wall is narrow and is formed by the upper part of the humerus
√ Lateral wall
name the 4 contents of the axilla
- Axillary artery and its branches
- Axillary vein and its tributaries
- Infraclavicular part of the brachial plexus
- Axillary Lymph nodes
