Iliac Artery Branches Chart

The common iliac arteries branch from abdominal aorta bifurcation at L4, each dividing into external iliac supplying lower limb via femoral and internal iliac feeding pelvis. Internal branches include superior…

Major Systemic Artery

Major systemic arteries begin with ascending aorta giving coronaries, arch branching brachiocephalic, left common carotid, left subclavian, then descending thoracic supplying intercostals, abdominal continuing as celiac, mesenteric, renal, gonadal, iliacs,…

Embroyonic Disc Amniotic Cavity Yolk Sac

The embryonic disc with amniotic cavity and yolk sac represents the early post-implantation stage, where the bilaminar disc of epiblast and hypoblast forms, then gastrulation creates a trilaminar disc with…
