Dorsalis pedis artery¹	Usually the continuation of the anterior tibial artery at the ankle joint	Travels over the dorsum toward the proximal first intermetatarsal space, usually lateral to the extensor hallucis longus tendon	Medial and lateral tarsal, first dorsal metatarsal and deep plantar branches; an arcuate artery is common but variable	Dorsal foot tissues and, through connections with the plantar arch, parts of the deep foot	not recorded

Thorax

Thorax - Vessel Territory Sheet. Every artery and vein in the reference with its origin, course, branches, and the territory it supplies or drains to, grouped by body region.
Vessel	Origin	Course	Branches	Supplies	Drains to
Accessory hemiazygos vein	Several left posterior intercostal veins in the upper-to-middle thorax	Descends along the left side of the vertebral bodies and commonly crosses posterior to central mediastinal structures near T7–T8	Middle left posterior intercostal tributaries, with variable communicating veins	Drains part of the left posterior thoracic wall	Azygos or hemiazygos pathways; communication with the left superior intercostal vein may occur
Anterior cardiac veins	Veins of the anterior right ventricular myocardium	Across the right AV junction toward atrial openings	Variable small ventricular tributaries, sometimes communicating with marginal veins	Drain the right ventricular wall; they do not provide arterial supply	Direct right atrial openings, bypassing the coronary sinus
Anterior interventricular artery (LAD)	Usually a major division of the left main coronary stem	Along the anterior interventricular groove toward the apex, with variable extension beyond it	Septal perforators and diagonal ventricular branches	Anterior left ventricular and septal myocardium, including much of the ventricular conducting system's arterial territory	The supplied region returns blood through the great cardiac vein and other connected venous channels

Abdomen

Abdomen - Vessel Territory Sheet. Every artery and vein in the reference with its origin, course, branches, and the territory it supplies or drains to, grouped by body region.
Vessel	Origin	Course	Branches	Supplies	Drains to
Abdominal aorta	Continues from the descending thoracic aorta through the aortic hiatus near T12.	Runs anterior to the lumbar vertebrae and left of the inferior vena cava in the retroperitoneum.	Gives celiac, superior and inferior mesenteric trunks; renal, gonadal and suprarenal branches; lumbar arteries and median sacral artery. Inferior phrenic origins vary.	Distributes blood to abdominal organs and walls, with terminal branches continuing to the pelvis and lower limbs.	This is an artery, not a draining vein; it ends by branching into the common iliac arteries.
Afferent arteriole	Usually arises from a cortical radiate, or interlobular, artery.	Approaches the corpuscle's vascular pole and divides into the glomerular capillary network.	Forms glomerular capillary loops; renin-containing granular cells concentrate near its glomerular end.	Delivers blood to the filtration bed, where water and small solutes enter capsular space across a selective barrier.	Glomerular blood leaves through an efferent arteriole before entering downstream capillary beds.
Celiac trunk¹	Usually the anterior abdominal aorta near T12–L1.	A short anterior trunk beneath the diaphragm; the order and pattern of division vary.	Typically left gastric, splenic and common hepatic arteries.	Supplies abdominal esophagus, stomach, proximal duodenum, liver, gallbladder, much of the pancreas and spleen through its branches.	not recorded

Pelvis

Pelvis - Vessel Territory Sheet. Every artery and vein in the reference with its origin, course, branches, and the territory it supplies or drains to, grouped by body region.
Vessel	Origin	Course	Branches	Supplies	Drains to
Common iliac veins	Union of internal and external iliac veins near each sacroiliac region.	Ascend toward the caval confluence; the left crosses obliquely behind the right common iliac artery.	May receive iliolumbar and sacral tributaries; median-sacral drainage commonly reaches the left side.	Return blood from pelvic, perineal and lower-limb territories.	Usually unite near L5 to form the inferior vena cava.
Internal iliac artery¹	One of the two terminal branches of the common iliac artery.	Passes posteromedially into the lesser pelvis and usually separates into anterior and posterior divisions near the greater sciatic foramen.	Posterior: iliolumbar, lateral sacral and superior gluteal. Anterior branches include vesical, obturator, internal pudendal, inferior gluteal and variable rectal and reproductive-organ arteries.	Most pelvic viscera, pelvic wall muscles, the gluteal region and perineum; some branches also contribute to the medial thigh.	not recorded
Lymphatic drainage of the anal canal^2,3	Begin in interconnected lymphatic networks within the anal wall.	Proximal channels follow rectal vessels into the pelvis; distal channels cross perineal tissue toward the groins.	not recorded	not recorded	Proximal canal: mesorectal/inferior mesenteric and internal iliac nodes. Distal canal: mainly superficial inguinal nodes, with communicating pathways.

Head & neck

Head & neck - Vessel Territory Sheet. Every artery and vein in the reference with its origin, course, branches, and the territory it supplies or drains to, grouped by body region.
Vessel	Origin	Course	Branches	Supplies	Drains to
Anterior cerebral artery¹	One of the terminal divisions of the internal carotid artery.	A1 usually crosses above the optic nerve toward ACom. Distal segments enter the longitudinal fissure, turn around the callosal genu and continue posteriorly.	Medial perforators, including the recurrent artery of Heubner; orbitofrontal, frontopolar, pericallosal and callosomarginal branches. Their origins and arrangement vary.	Much medial frontal/parietal cortex, including paracentral lobule, and most of the corpus callosum anterior to the splenium. Perforators supply parts of anterior basal ganglia and internal capsule.	not recorded
Anterior communicating artery¹	A connection between right and left ACAs at or near their A1–A2 transitions, rather than a vessel with one universally designated parent side.	Spans the midline above the optic apparatus in the basal interhemispheric region; orientation and number of channels vary.	Variable perforators toward the optic chiasm, hypothalamus, subcallosal/basal-forebrain region and related callosal structures.	Allows cross-flow between ACAs and directly perfuses small adjacent neural territories through its branches.	not recorded
Anterior inferior cerebellar artery (AICA)¹	Usually the lower or middle basilar trunk; occasional alternative origins and duplicated vessels occur.	Travels posterolaterally from the pons into the cerebellopontine region, with a variable loop near the internal acoustic meatus and VII/VIII.	Pontine perforators, cerebellar branches and usually the labyrinthine artery; the latter can instead arise from another parent vessel.	Variable portions of lower lateral pons, middle cerebellar peduncle, flocculus and anteroinferior cerebellum. A labyrinthine branch serves cochlear and vestibular structures.	not recorded
