Superior and inferior gluteal arteries

Supply the gluteal region.

Supplies the medial muscles of the thigh.

Internal pudendal artery

Supplies the anal canal and perineum.

Middle rectal artery

Supplies the lower portion of the rectum.

Uterine and vaginal arteries

Supply the uterus and vagina, if present.

Lateral sacral arteries

Supply the region around the sacrum.

Vesical arteries

Supply the bladder and prostate, if present.

Pelvis and perineum venous drainage

Drained by veins with the same names as the supplying arteries into the internal iliac vein.

Internal and external iliac veins merge

They form the common iliac vein.

Common iliac vein drainage

Drains into the inferior vena cava.

Main arterial vessel for upper limb

The subclavian artery.

Left subclavian artery origin

Originates directly from the aortic arch.

Right subclavian artery origin

Originates from the brachiocephalic trunk.

Major branches of the subclavian artery

Vertebral artery, thyrocervical trunk, internal thoracic artery, and costocervical trunk.

Subclavian artery after first rib

Becomes the axillary artery.

Axillary artery supplies

Supplies the shoulder and thoracic region.

Branches of the axillary artery

Superior thoracic, thoracoacromial, lateral thoracic, humeral circumflex, and subscapular arteries.

Axillary artery after teres major

Becomes the brachial artery.

Brachial artery travel

Travels alongside the humerus.

Deep brachial artery

Also known as the profunda brachii artery or deep artery of the arm.

Deep brachial artery supplies

Supplies most of the muscles of the arm.

Brachial artery division location

Divides in the cubital fossa.

Brachial artery divides into

Ulnar artery and radial artery.

Radial and ulnar arteries supply

Supply the forearm and wrist.

Radial and ulnar arteries in palm

Anastomose to form two arterial arches.

Two arterial arches of the palm

Superficial palmar arch and deep palmar arch.

Artery forming superficial palmar arch

Typically the ulnar artery.

Artery forming deep palmar arch

Typically the radial artery.

Branches from palmar arches to fingers

Digital arteries.
