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)
