https://youtu.be/6ERqFvK50Ek This is my second overview on the veins of the human body—with the full human-body vein names—for my biotech R&D, especially in human longevity biotech and other medical biotechnologies. Wikipedia is used as the main reference. I haven't had the time to check the proper pronunciations, so I'll improve my pronunciations in the next version, and mispronounce some, if not all, words in this version. The human-body veins include veins of the heart, pulmonary veins, superior vena cava (SVC) vein, inferior vena cava vein, hepatic portal vein. Veins of the heart include coronary sinus vein, which include great cardiac vein, oblique vein of left atrium, middle cardiac vein, small cardiac vein. Superior vena cava (SVC) vein includes brachiocephalic vein, internal jugular vein, cerebral veins, orbital veins, azygos vein, veins of upper limb. Brachiocephalic vein includes inferior thyroid vein, inferior laryngeal vein, pericardial veins, pericardiophrenic veins, bronchial veins, vertebral vein, deep cervical vein, internal thoracic veins, supreme intercostal vein. Vertebral vein includes occipital vein, and anterior vertebral vein. Internal thoracic veins include superior epigastric veins, musculophrenic veins, and anterior intercostal veins. Internal jugular vein includes lingual vein, superior thyroid vein, middle thyroid veins, sternocleidomastoid vein, superior laryngeal vein, facial vein, retromandibular vein, external jugular vein, dural venous sinuses, diploic veins, emissary veins. Lingual vein includes dorsal lingual veins, sublingual vein, and deep lingual vein. Facial vein includes angular vein, supratrochlear veins, supra-orbital vein, external nasal veins, deep facial vein, external palatine vein, submental vein. Retromandibular vein includes superficial temporal veins, middle temporal vein, transverse facial vein, maxillary veins, pterygoid plexus. External jugular vein includes posterior auricular vein, anterior jugular vein, suprascapular vein, transverse cervical veins. Dural venous sinuses include transverse sinus, confluence of sinuses, marginal sinus, occipital sinus, petrosquamous sinus, sigmoid sinus, superior sagittal sinus, inferior sagittal sinus, straight sinus, inferior petrosal sinus, superior petrosal sinus, cavernous sinus, sphenoparietal sinus. Cerebral veins include superficial cerebral veins, internal cerebral veins, veins of brainstem, cerebellar veins. Internal cerebral veins include basal vein, and great cerebral vein.
