Blood Vessels And Nerves Of Head (+ Clinical Signifcance ) Flashcards
What does the Superficial temporal supply?
supplies the frontal and temporal regions
What does the posterior auricular supply?
supplies the area superiorly and posteriorly to the auricle
What does the occipital supply?
supplies the back of the scalp
Anteriorly and superiorly, the scalp receives additional supply from two branches of the…. called …
 ophthalmic artery – the supraorbital and supratrochlear arteries.
The scalp receives cutaneous innervation from …..
branches of the trigeminal nerve or the cervical nerve roots.
Trigeminal Nerve Derivatives
Supratrochlear nerve
Supraorbital nerve
Zygomaticotemporal nerve Auriculotemporal nerve
Cervical nerves derivatives
Greater occipital nerve
Lesser occipital nerve
Third occipital nerve
Greater auricular nerve
•Supratrochlear nerve
branch of the ophthalmic nerve which supplies the anteromedial forehead
Supraorbital nerve
branch of the ophthalmic nerve which supplies a large portion of the scalp between the anterolateral forehead and the vertex
Zygomaticotemporal nerve
branch of the maxillary nerve, this supplies the temple.
Auriculotemporal nerve
branch of the mandibular nerve which supplies skin anterosuperior to the auricle.
Lesser occipital nerve
derived from the anterior ramus (division) of C2 and supplies the skin posterior to the ear
Greater occipital nerve
derived from the posterior ramus (division) of C2 and supplies the skin of the occipital region.
Great auricular nerve
derived from the anterior rami of C2 and C3 and supplies the skin posterior to the ear and over the angle of the mandible
Third occipital nerve
derived from the posterior ramus of C3 and supplies the skin of the inferior occipital region.
