Maxillary and Ophthalmic Arteries Quiz

The pharyngeal branch supplies the posterior aspect of the roof of the nasal cavity, the sphenoidal sinus, and the auditory tube.

The primary function of the sphenopalatine artery is to give off the posterior lateral nasal arteries and posterior septal branches, supplying the lateral wall and septum of the nasal cavity.

The nasopalatine branch descends along the nasopalatine groove to the incisive canal and exits through the incisive foramen, anastomosing with the descending palatine artery to supply the anterior part of the hard palate.

The common carotid artery (CCA) is a major blood vessel that supplies blood to the head and neck. It originates from the brachiocephalic trunk on the right side and the aortic arch on the left side.

The CCA ascends through the neck, located near the trachea and esophagus, and is encased in a sheath called the carotid sheath.

The carotid sheath is a fibrous connective tissue that surrounds the CCA, internal jugular vein, and vagus nerve.

The CCA bifurcates, or splits, into two branches at the upper border of the thyroid cartilage, around the level of the fourth cervical vertebra (C4).

The internal carotid artery (ICA) supplies blood to the brain and eyes.

The external carotid artery (ECA) supplies blood to the face, neck, and scalp.

The left and right common carotid arteries follow the same course, except for their origins.

The CCA does not give off any branches before it bifurcates.

The ophthalmic artery arises from the internal carotid artery, enters the orbit through the optic canal, and supplies the orbital content.

The central retinal artery is a branch of the ophthalmic artery that supplies the retina, the light-sensitive lining at the back of the eye.

The lacrimal artery, a branch of the ophthalmic artery, runs along the upper border of the lateral rectus muscle and supplies the lacrimal gland, which produces tears.

The supraorbital artery, a branch of the ophthalmic artery, travels with the supraorbital nerve and supplies the forehead, superior rectus muscle, and levator palpebrae superioris muscle, which raises the eyelid.

The anterior ethmoidal artery, a branch of the ophthalmic artery, passes through the anterior ethmoidal canal to supply the ethmoidal and frontal air sinuses, cavities in the skull.

The posterior ethmoidal artery, a branch of the ophthalmic artery, travels through the posterior ethmoidal canal and supplies the posterior ethmoidal air sinuses.

The ophthalmic artery anastomoses with the facial, maxillary, and transverse facial arteries, forming connections with other blood vessels in the head.

The ophthalmic artery, a branch of the internal carotid artery, supplies the orbital contents and anastomoses with other arteries in the head, ensuring blood flow to the eye and surrounding structures.

The ophthalmic artery is a branch of the internal carotid artery that supplies blood to the eye, forehead, and nasal cavity.

It ascends on the forehead, supplies the skin, muscles, and pericranium, and anastomoses with the supraorbital artery.

The dorsal nasal artery emerges from the orbit, gives a branch to the nasolacrimal sac, and joins the facial artery. Another branch runs along the nose's dorsum to supply the outer surface.

The vertebral arteries originate from the subclavian arteries, ascend through the foramina transversaria of the upper six cervical vertebrae, enter the cranial cavity through the foramen magnum, and converge medially to form the basilar artery.

The basilar artery is a large median vessel formed by the union of the vertebral arteries at the mid-medullary level. It gives rise to cerebellar arteries and ends by dividing into two posterior cerebral arteries.

The Circle of Willis is a large arterial anastomosis that unites the internal carotid and vertebrobasilar systems. It ensures that blood flow to the brain is maintained even if one of the major arteries is blocked.

The Circle of Willis is a safety mechanism that ensures blood flow to the brain is maintained, even if one of the major arteries is blocked.

The Circle of Willis is a loop of arteries at the base of the brain that connects the internal carotid arteries and the vertebral arteries.

A branch of the pterygopalatine portion of the maxillary artery that supplies the posterior roof of the nasal cavity, sphenoidal sinus, and auditory tube.

A branch of the maxillary artery that travels through the pterygoid canal and contributes to the blood supply of the upper pharynx, auditory tube, and tympanic cavity.

A terminal branch of the maxillary artery, this vessel passes through the sphenopalatine foramen and gives rise to lateral and septal branches.

Branches of the sphenopalatine artery that supply the outer wall of the nasal cavity and related sinuses.

Branches of the sphenopalatine artery that supply the nasal septum, the dividing wall of the nose.

The inferior labial artery branches from the facial artery and supplies the lower lip's glands, mucous membrane, and muscles. It connects (anastomoses) with the same artery on the opposite side and the mental branch of the inferior alveolar artery.

The superior labial artery branches off the facial artery and supplies the upper lip. It has a septal branch, providing blood to the nasal septum, and an alar branch for the ala of the nose.

The lateral nasal branch originates from the facial artery and delivers blood to the ala and dorsum of the nose.

The muscular branches of the facial artery supply muscles in both the neck and face. These include the pterygoideus internus and stylohyoid in the neck, and the masseter and buccinator in the face.

The angular artery is the terminal branch of the facial artery and ascends to the inner corner of the eye. Here, it supplies the lacrimal sac and orbicularis oculi muscles, before joining (anastomosing) with the dorsal nasal branch of the ophthalmic artery.

The occipital artery arises from the back of the external carotid artery, opposite the facial artery, and ends in the back of the scalp. It supplies the muscles and tissues of the posterior scalp.

The Circle of Willis is located in the subarachnoid space and surrounds the optic chiasma and infundibulum.

The Circle of Willis is formed by the anterior cerebral arteries, anterior communicating artery, posterior cerebral arteries, posterior communicating arteries, and internal carotid arteries.

The external carotid artery is a major blood vessel that supplies blood to the face, neck, and scalp.

The external carotid artery divides into the superficial temporal and internal maxillary arteries at superior to the angle of the mandible.

The superior thyroid artery arises from the external carotid artery and supplies the thyroid gland, anastomosing with its fellow of the opposite side, and with the inferior thyroid arteries. It also branches to the Sternocleidomastoid and Superior Laryngeal Artery.

The external carotid artery gives off anterior, posterior, and medial branches to supply the face, neck, and scalp.

The external carotid artery plays a vital role in supplying blood to the structures of the head and neck, including the thyroid gland, larynx, face, and scalp.
