Study Notes
External Jugular Vein
- Forms from the union of the anterior jugular, cervical, and suprascapular veins.
- Empties into the subclavian vein.
- Branches can be remembered with the pneumonic PAST:
- Posterior External Jugular
- Anterior Jugular
- Suprascapular
- Transverse Cervical
Posterior Retromandibular Vein
- Formed from the superficial temporal and maxillary veins.
- Superficial temporal vein drains the scalp.
Internal Jugular Vein
- Empties into the subclavian vein.
- Tributaries can be remembered with the pneumonic: MSLCPI
- Middle Thyroid (Many)
- Superior Thyroid (Schools)
- Lingual (Let)
- Common Facial (Confident)
- Pharyngeal (People)
- Inferior Petrosal Sinus (In)
Inferior Petrosal Sinus
- Drains large parts of the brain and inner ear.
- Other tributaries include the vein of the cochlear duct and meningeal veins.
Common Facial Vein
- Formed by the confluence of the facial vein and anterior retromandibular vein.
- Drains the forehead, eyelids, outer surface of the nose, lips, submental region, masseter, parotid gland, and soft palate.
Facial Vein
- Formed by the convergence of numerous veins:
- Supraorbital
- Supratrochlear
- External Nasal
- Angular
- Submental
- Inferior Labial
- Superior Labial
- Buccal
- Transverse Facial
- Retromandibular
Clinical Significance
- Important to be aware of the venous supply to the head and neck when administering inferior dental nerve blocks.
- Accidental puncture of these vessels can lead to hematoma formation.
- Understanding the pterygoid plexus is crucial for local anesthetic administration and managing dental infections.
Notes
- Not all vessels join identically in every case.
- There may be variations in the venous anatomy due to individual variations.
