How is angular vein formed?
The angular vein drains the anterior region of the scalp 1. It is formed by the union of the supratrochlear and supraorbital veins and becomes the facial vein 1,2,3.
Where is retromandibular vein located?
The retromandibular vein, also known as the posterior facial vein, is a deep vein of the face that is formed by the merger of the superficial temporal vein with the maxillary vein. It runs within the substance of the parotid gland, descending posterior to the ramus of the mandible.
What is Retromandibular groove?
An obsolete term for a wedged space posterior to the ramus of the mandible and anteroinferior to the external auditory meatus, which is primarily occupied by the parotid gland.
Where is the angular vein located?
The angular vein (v. angularis) formed by the junction of the supratrochlear and supraorbital veins, runs obliquely downward, on the side of the root of the nose, to the level of the lower margin of the orbit, where it becomes the anterior facial vein.
Which vein drains blood from the lateral region of the face?

What is the angular vein?
What is angular artery?
The Angular Artery is the terminal part of the external maxillary; it ascends to the medial angle of the orbit, imbedded in the fibers of the angular head of the Quadratus labii superioris, and accompanied by the angular vein.
What vein goes to the brain?
The brain is a tremendously well-perfused organ, receiving up to 20% of the resting cardiac output. This blood flow reaches the brain via the internal carotid arteries and the vertebral arteries and ultimately gets drained by the internal jugular veins.
What does retromandibular vein drain?
The anterior branch anastomoses with the facial vein and forms the common facial vein, while the posterior branch anastomoses with the posterior auricular veins, forming the external jugular vein. The retromandibular vein drains the venous blood from the jaw, the lateral skull, and the parotid gland.

Where is the angular artery located?
The angular artery is the terminal part of the facial artery; it ascends to the medial angle of the eye’s orbit, imbedded in the fibers of the angular head of the Quadratus labii superioris, and accompanied by the angular vein.
The angular vein continues through the face as the facial vein, which drains much of the blood from the face. In rare cases, two angular veins may result from a split of the trunk at the top of the nose.
What is the angular vein of the orbit?
Veins of orbit. The angular vein is the upper most segment of the facial vein, above its junction with the superior labial vein. It is formed by the junction of the supratrochlear vein and supraorbital vein, runs obliquely downward by the side of the nose, passes under zygomaticus major and joins with the superior labial vein .
How is the angular vein of the nose formed?
It is formed by the junction of the supratrochlear vein and supraorbital vein, runs obliquely downward by the side of the nose, passes under zygomaticus major and joins with the superior labial vein . The angular vein is linked with the cavernous sinus by the superior and inferior ophthalmic veins which are devoid of valves.
What causes swelling of the angular vein?
Swelling of the angular vein is rare but may be caused by genetic factors, trauma, tissue abnormality, or a chronic blood flow obstruction. The only risk from such a varix is a small chance of intracranial air embolus, which is when air enters the veins, a potentially deadly event.
