Blood Supply to the Head and Neck

The left common carotid artery arises directly from the aortic arch.

The right common carotid artery originates from the brachiocephalic artery.

The right and left common carotid arteries supply both sides of the head and neck.

The internal carotid artery supplies the brain, forehead, and part of the nose.

The internal carotid artery travels deep into the face, through the carotid canal in the skull base.

The external carotid artery is one of the two main branches of the common carotid artery.

The common carotid artery splits into the internal and external carotid arteries.

The Posterior Auricular Artery provides blood to muscles in the posterior neck, the skin covering and surrounding the ear, and the ear itself.

This artery supplies blood to the skin and muscles of the scalp, the parotid gland, and the temporomandibular joint.

The Superficial Temporal Artery is one of the two main branches of the External Carotid Artery, along with the Maxillary Artery.

The Maxillary Artery supplies a variety of important structures in the head and neck.

While the Maxillary Artery has many branches, you don't need to memorize all of them. Focus on understanding its overall role in supplying the head and neck.

The External Carotid Artery branches into the Superficial Temporal Artery and the Maxillary Artery, which are the two main branches of the External Carotid Artery.

The External Carotid Artery is one of the two major branches of the Common Carotid Artery, along with the Internal Carotid Artery.

The Internal Carotid Artery supplies blood to the brain, forehead, and part of the nose.

The main source of blood supply to the head and neck originates from the aortic arch.

The brachiocephalic artery splits into the right subclavian and right common carotid arteries.

The right subclavian artery supplies blood to the right upper limb and also gives rise to the right vertebral artery.

The right common carotid artery branches into the internal and external carotid arteries, supplying blood to the right side of the head and neck.

The left common carotid artery arises directly from the aortic arch.

The left subclavian artery supplies blood to the left upper limb and also gives rise to the left vertebral artery.

The left common carotid artery branches into the internal and external carotid arteries, supplying blood to the left side of the head and neck.

Both right and left vertebral arteries supply blood to the spinal cord and vertebral muscles.

The terminal portion of the lingual artery responsible for providing blood supply to the body of the tongue.

The lingual artery provides blood to the tongue, sublingual gland, and the mucous membranes lining the inside of the cheek and gums.

The facial artery branches repeatedly to supply blood to the muscles and skin of the face, including those around the submandibular gland.

The facial artery plays a crucial role in supplying blood to the structures in the face.

The occipital artery supplies blood to the muscles at the back of the neck, the skin of the neck and ear, and the scalp in the occipital region.

The Occipital Artery helps provide blood flow for movement and sensation in the posterior neck and scalp.

The superior thyroid artery supplies blood to the thyroid gland, some neck muscles, and the larynx.

The ascending pharyngeal artery supplies blood to the pharynx, soft palate, and prevertebral muscles.

The sublingual artery supplies blood to the sublingual gland, muscles in the floor of the mouth, and buccal and gingival mucous membranes.

The dorsal lingual artery supplies blood to the base of the tongue, palatoglossal arch, tonsils, soft palate, and epiglottis.

The lingual artery branches into the sublingual, dorsal lingual, and deep lingual arteries, supplying various structures in the tongue and surrounding areas.

The diagrams show the location of arteries and their branches in the head and neck, highlighting their relationships to other structures.

The labels in the diagrams indicate the names of the arteries and their subdivisions, allowing for clear identification.

The external carotid artery is one of the two branches of the common carotid artery and provides the majority of the blood supply to the head and neck, excluding the brain.

The internal carotid artery is one of the two branches of the common carotid artery and is primarily responsible for supplying blood to the brain, forehead, and part of the nose.

The common carotid artery splits into two main branches: the internal carotid artery and the external carotid artery. The internal carotid artery supplies blood to the brain, while the external carotid artery supplies blood to the rest of the head and neck.
