What does the supratrochlear vein do?
After spreading across the forehead, it anastomoses with its contralateral counterpart and the supraorbital artery. The supratrochlear artery supplies the upper eyelid, periosteum, as well as the muscles of the forehead and adjacent skin.
Why do the veins in my head pop out?
Bulging veins can appear anywhere on the body, including the forehead. Veins can expand due to pressure or stress. Skin changes associated with aging may make veins in the forehead appear larger than they are. Genetic factors or age can influence whether someone gets large veins on their forehead.

Is there a vein above your eyebrow?
The supraorbital vein begins on the forehead where it communicates with the frontal branch of the superficial temporal vein. It runs downward superficial to the Frontalis muscle, and joins the frontal vein at the medial angle of the orbit to form the angular vein.
What does supratrochlear artery supply?
Arising from the ophthalmic branch of the internal carotid system, the supratrochlear artery supplies the midline forehead flap. This is probably the oldest flap in history and still has a place today. The artery runs over the medial one-third of the supraorbital rim to supply the midline forehead up to the vertex.
Is the Supratrochlear nerve a cranial nerve?
Cranial Nerve Innervation of Ocular Structures Sensory fibers from the skin and muscles of the forehead and upper eyelid come together and form the supratrochlear nerve. This nerve enters the orbit by piercing the superior medial corner of the orbital septum (Figure 12-4).
Can stress cause veins to pop out?
If you are overworked or stressed out, you may be jeopardizing the health of your veins. Stress and anxiety cause the blood pressure to rise, and this can result in increased pressure within the veins.
What are scalp veins?
The scalp veins primarily drain the deoxygenated blood from the epicranial aponeurosis and the frontal and occipital belly of the occipitofrontalis muscle, the temporalis muscle, the auricularis superior muscle, the temporoparietalis muscle, the auricularis anterior muscle, and the auricularis posterior muscles.
What is a vortex vein?
The vorticose veins, referred to clinically as the vortex veins, drain the ocular choroid. The number of vortex veins is known to vary from 4 to 8 with about 65% of the normal population having 4 or 5. In most cases, there is at least one vortex vein in each quadrant.
Where is the Supraorbital vein?
The supraorbital vein (v. supraorbitalis) begins on the forehead where it communicates with the frontal branch of the superficial temporal vein. It runs downward superficial to the Frontalis muscle, and joins the frontal vein at the medial angle of the orbit to form the angular vein.
What is supraorbital neuralgia?
Supraorbital neuralgia is a rare disorder clinically characterized by the following triad: 1) forehead pain in the territory supplied by the supraorbital nerve, without side shift; 2) tenderness on either the supraorbital notch or traject of the nerve; and 3) absolute, but transitory relief of symptoms upon …
What is ophthalmic vein?
Ophthalmic veins are veins which drain the eye. More specifically, they can refer to: Superior ophthalmic vein. Inferior ophthalmic vein.
Are there any cases of palpation of the supratrochlear nerve?
Palpation of the supratrochlear nerve at the medial third of the supraorbital rim resulted in hypersensitivity in all cases. All but one patient exhibited sensory disturbances within the painful area. Fourteen patients underwent anesthetic blockades of the supratrochlear nerve, with immediate relief in all cases and long-term remission in three.
Is the trochlear nerve part of the supraorbital artery?
It is accompanied by the trochlear nerve and supratrochlear vein. After spreading across the forehead, it anastomoses with its contralateral counterpart and the supraorbital artery .
Is the supratrochlear nerve block performed over the forehead?
The supratrochlear nerve block is often performed in conjunction with the supraorobital nerve block to achieve regional anesthesia over the ipsilateral forehead.
Where does the supratrochlear vein enter the nose?
The supratrochlear vein descends down the medial part of the forehead until it reaches the root of the nose where it is connected to its contralateral partner by the transverse nasal arch 2.
