Which artery runs along the radial side of the forearm?
Radial artery.
Which arteries anastomose with the dorsal scapular artery?
Subscapular and circumflex scapular arteries.
Which veins does the median cubital vein connect?
The cephalic vein and the basilic vein.
What is the commonly chosen site of venipuncture?
The median cubital vein.
Where does the radial artery run in relation to the brachioradialis tendon?
Medial to the brachioradialis tendon.
What happens to blood flow in the subscapular artery when the axillary artery is occluded above its origin?
The direction of blood flow is reversed.
What is the function of the brachioradialis tendon?
It assists in flexing the forearm at the elbow.
What anatomical structures are associated with the brachial artery at the cubital fossa?
It is covered superficially by the bicipital aponeurosis, lies medial to the biceps tendon, and lateral to the median nerve.
What muscles does the dorsal scapular artery travel deep to?
Levator scapulae and rhomboid muscles.
Where does the subscapular artery travel after originating from the axillary artery?
Follows the inferior margin of the subscapularis muscle, crosses the teres major muscle anteriorly, and reaches the inferior angle of the scapula.
Where does the brachial artery travel in the arm?
Down the medial aspect of the arm to reach the cubital fossa.
Where can the radial pulse be palpated?
Medial to the brachioradialis tendon or styloid process of radius and lateral to the FCR tendon at the lateral side of the wrist.
How does the suprascapular artery course after its origin?
Travels laterally, roughly parallel to the clavicle, crosses over the suprascapular notch, and travels deep to the supraspinatus muscle.
How does the circumflex scapular artery course?
Travels along the lateral border of the scapula, through the triangular space, and into the infraspinous fossa.
Through which canal does the ulnar artery enter the hand?
Guyon’s canal.
What purposes can the median cubital vein be used for?
Drawing blood, transfusion, IV injection, and catheter insertion.
What is the dorsal venous arch of the hand commonly used for?
Intravenous feeding and venous cutdown.
Where can the ulnar pulse be palpated?
Lateral to the pisiform bone or lateral to the FCU tendon at the medial side of the wrist.
Where does the dorsal scapular artery travel after originating from the subclavian artery?
Laterally and posteriorly through the trunks of the brachial plexus to the superior angle of the scapula.
What is venous cutdown?
An emergency procedure where a vein is exposed surgically, followed by cannula insertion under direct vision.
Which arteries anastomose on the anterior aspect of the scapula?
Dorsal scapular artery and subscapular artery.
What anatomical structure does the radial artery travel across to reach the dorsal aspect of the hand?
The scaphoid and trapezium.
What occurs if the site of occlusion is below the origin of the subscapular artery?
There would be no way for blood to perfuse the upper limb.
Where does the ulnar artery run in relation to the flexor carpi ulnaris muscle?
Lateral to the flexor carpi ulnaris (FCU) muscle.
How can the brachial pulse be taken?
By palpating the brachial artery at the cubital fossa.
Which artery anastomoses with the suprascapular artery?
Dorsal scapular and circumflex scapular arteries.
What does the FCR tendon refer to?
Flexor carpi radialis tendon, which helps in wrist flexion.
What is the significance of the scapular anastomosis?
It allows blood to flow from the subclavian artery to the third part of the axillary artery when the axillary artery is ligated or occluded above the origin of the subscapular artery.
What is the origin of the suprascapular artery?
Thyrocervical trunk of the subclavian artery.
How can haemorrhage of the upper limb be controlled?
By compressing the brachial artery at the middle of the arm.
Where is the cuff placed for blood pressure measurement at the brachial artery?
Around 2 cm above the elbow crease.
What is the origin of the subscapular artery?
Third part of the axillary artery.
What is the origin of the dorsal scapular artery?
Subclavian artery.
What separates the median cubital vein from the brachial artery and median nerve?
The bicipital aponeurosis.
What is the purpose of placing the stethoscope over the brachial pulse during blood pressure measurement?
To listen for Korotkoff sounds.
What is the origin of the circumflex scapular artery?
Thyrocervical trunk of the subclavian artery.
Where does the dorsal venous arch run?
Superficially across the dorsal aspect of the metacarpals.
