 Superficial venous drainage is in what fascia? | Superficial fascia |
| Posterior auricular vein (OP) | O - a plexus of veins in scalp behind ear P - descends across upper part of SCM where is unites with retromandibular v |
| Retromandibular vein (OPD) | O - formed in upper portion of parotid gland by confluens of superficial temporal & maxillary vv. Receives branches from pterygoid plexus of vv P - descends post to ramus of mandible thru parotid gland D - gives rise to ant descending communication which joins facial v below angle of mandible |
| Ext jugular vein formed by | retromandibular veins joining posterior auricular vein |
| Pterygoid plexus of veins important where? | important between temporalis & lat pterygoid muscles and between 2 pterygoid mm & around maxillary a |
| Pterygoid plexus of veins (connections) | with facial vein via cavernous sinus & inferior/sup ophthalmic veins & retromandibular vein. Direct connections with cavernous sinus |
| External jugular vein (PD) | P - crosses SCM perpendicularly, descends toward middle of clavicle, pierces investing layer of cervical fascia 2 cm above clavicle in post triangle. D - Ends in subclavian vein |
| Valves of external jugular vein | Subclavian vein, 4 cm above |
| Other veins external jugular receives from shoulder | transverse cervical, suprascapular veins |
| Anterior jugular vein (OD) | O - begins near hyoid bone by confluens of small veins of submental & submandibular regions D - external jugular vein (no valves) |
| Anterior jugular vein (P, tissue) | descends near medial line in subcutaneous CT. About 3cm above manubrium the vein perforates superficial layer of cervical fascia. Here it unites with ant jugular of other side in suprasternal region. Turns laterally, passes close behind sternocleidomastoid m. Empties into external jugular |
| Facial vein (P) | follows --- artery thru face. Begins with supraorbital & supratrochlear vv, has communication around orbit with sup & inf ophthalmic vv in orbit |
| Superior ophthalmic vein (PD) | P - along roof of orbit thru sup orbital fissure D - cavernous sinus |
| Inferior ophthalmic vein (PD) | P - along floor of orbit thru sup orbital fissure D - pterygoid plexus of veins, then cavernous sinus |
| Where does facial vein communicate with retromandibular vein? | below angle of the mandible |
| Occipital vein (O) | Begins as plexus of veins in occipital region of scalp |
| Occipital vein communication, branches | Communication with post auricular vein. Branches that descend with --- artery which pierce trapezius muscle & empty into a plexus of veins in suboccipital triangle. |
| Occipital veins (D) | vertebral veins & deep cervical veins |
| Internal jugular vein (fact, OP) | largest vein of head & neck. O - collects blood from brain, superficial parts of face, neck. Begins at jugular foramen in skull where there is a dilatation called the superior bulb. P - descends in carotid sheath with int & common carotid and vagus |
| Superior bulb | Dilation in internal jugular vein at jugular foramen |
| Pharyngeal veins (OD) | O - arise from a venous plexus on wall of pharynx D - internal jugular at angle of mandible |
| Common facial vein (OD) | O - continuation of facial vein at ant margin of SCM after it receives communication from a retromandibular vein D - internal jugular at level of hyoid |
| Lingual vein (OD) | O - arises from veins on dorsum, sides, and under surface of tongue D - empties into internal jugular at level of origin of --- artery from ex carotid artery |
| Superior thyroid vein (D) | empties into internal jugular above thyroid cartilage |
| Inferior thyroid vein (PD) | P - descends on surface of trachea D - drains directly into R/L brachiocephalic veins behind manubrium |
| Thyroid ima vein | when R & L inferior thryoid veins unite to form a single vein, which empties into L brachiocephalic vein |
| Inferior jugular bulb | Just above its termination into internal jugular, has a dilation called inferior bulb. Also has a single bicuspid valve to prevent upward flow of blood into internal jugular |
| Inferior bulb | Inferior dilation on inferior jugular bulb |
| Brachiocephalic vein | behind sternoclavicular joint the internal jugular & subclavian veins for R/L --- . Drains into superior vena cava. |
