This video will cover the: • External veins of the head and face • External Jugular Vein • Internal Jugular Veins • Through a scheme (which schematically show the course, tributaries and drainage). • Content of the video: • 0:00 Introduction • 2:26 External Veins of the Head • 6:41 Internal Jugular Vein • 8:50 External Jugular Vein • 9:53 Quiz • ------------------------------- • 🫀 Join: / @taimtalksmed • 📷 Follow my IG: / taimtalksmed • 💝 Donation link: https://www.buymeacoffee.com/taimtalk... • ------------------------------- • Intro: • Venous system consists of 4 parts: • ○ Veins of the heart • ○ Vena cava superior • ○ Vena cava Inferior • ○ Portal system • Venous Tributaries: smaller veins that empty into larger veins • Superior vena cava divides into two brachiocephalic veins. Brachiocephalic vein is formed by the internal jugular and the subclavian vein. The external jugular empties into the subclavian vein. • Veins of the head: • Internal Jugular (Vena Jugularis Interna) drains from the Sigmoid Sinus (Sinus Sigmoideus) • ○ Lingual Vein (v. Lingua) • § Dorsal lingual vein (vena dorsalis lingua) • § Deep lingual vein (vena profunda lingua) • § Sublingual vein (vena sublingualis) • ○ Common facial vein • § Facial vein (Vena facialis) • □ Deep facial vein (vena facialis profunda) towards the infratemporal fossa (fossa infratemporalis)and form: • □ Pterygoid plexus (plexus pterygoideus) continus as Maxillary Vein (vena maxillaris) • □ Maxillary vein connects with the Retromandibular vein (vena retromandibularis) and form the Superficial temporal vein (vena temporalis superficialis) • □ Superficial Temporal Vein supply parietal and frontal region with blood • § Anterior root of retromandibular vein connects with the posterior root of retromandibular vein and form the Retromandibular vein • External Jugular Vein (Vena Jugularis Externa) • ○ Formed by the posterior root of retromandubular vein and the posterior auricular vein (vena auricularis posterior) • Occipital Vein (vena occipitalis) - Variations!! • ○ Empty into the Posterior auricular vein and form the posterior root of the external jugular vein which then empty into the external jugular • ○ Empty directly into the internal jugular • Veins of the neck: • Internal Jugular vein Mnemonic: • ○ Medical Schools Let Confident People In • ○ M: Middle Thyroid (vena thyroidea media) • ○ S: Superior Thyroid (vena thyroidea superior) • ○ L: Lingual Vein (vena lingualis) • ○ C: Common facial vein • ○ P: Pharyngeal vein (vena pharyngea) - drains pharyngal plexus • ○ I: Inferior petrosal sinus (sinus petrosus inferior) • External Jugular vein Mnemonic: • ○ PAST • ○ P: Posterior external jugular vein • ○ A: Anterior jugular vein (vena jugularis antrior) -- Jugular venous arch • ○ S: Suprascapular vein (vena suprascapularis) • ○ T: Transverse cervical vein (Vv. transversae colli) • QUIZ: • Can you fill in the blanks in this quiz?! :)
