Maxillary Artery Branches, Course & Mnemonic

The maxillary artery also referred as an internal maxillary artery, it is one of the two terminal divisions between the continuations external carotid artery. The second terminal branch is called superficial temporal artery. That is why the maxillary artery can be described as one of the continuations external carotid artery, and supplies the oxygenated blood maxilla and mandible, jaw bones, deep facial areas, cerebral dura mater and the nasal cavity respectively. Hence it is referred a blood vessel which assists both hard and soft tissues in the maxillofacial portion.

Learn About Internal Thoracic Artery And Its Branches

The prominent trunk of the maxillary artery is separated into three portions, that are classified as per to related structures along the artery’s course. These three portions are the:

  • Mandibular part (1st part) – named as such because it winds around deep to the neck of the mandible,
  • Pterygoid part (2nd part) – it has this name because it travels between the two heads of the lateral pterygoid muscle,
  • Pterygopalatine part (3rd part) – this part derived its name from the pterygopalatine fossa, into which it enters.

Therefore, these three main portions are defined as the part before-, part on-, and part beyond the lateral pterygoid muscle separately. This artery has very much importance, as emerging out of the fifteen lateral branches of the maxillary artery, the five branches from the second portion, and are considered as branches to soft tissues and they do not course via foramina in bones. While, the rest ten branches, from the first and third portions, run through foramina in bones.

Course Of Maxillary Artery:

The maxillary artery branches off as one of the terminal divisions of the continuations external carotid artery at the plane of the neck of the mandible and runs forwards in between the neck portion of the mandible and the sphenomandibular ligament (a very sensitive part). It goes through its path by moving deeply to the bottom head and passes forward between the two heads portion of the lateral pterygoid muscle to break into its lateral branches at the pterygopalatine fossa.

Branches Of Maxillary Artery:

Ok, so now that opening to this lesson lastly makes very much sense, let’s see how we can use it, but keep in your mind all that 17 mentioned branches.

Deep auricular artery:

Deep auricular artery branch goes in deep in the ear. Auricular means ‘relating to hearing’ so it shouldn’t be astonishing to read that this vessel delivers blood flow to the deep ear canal and the behalf surface of the tympanic membrane talking about the ear drum.

Anterior tympanic artery:

This is actually the couple of branches that runs near the tympanic membrane. It crosses deep to the membrane, through the Petro tympanic fissure to the mid ear in order to attach with the circular anastomosis that is located around the tympanic membrane.

Middle meningeal artery:

This one proceeds straight upwards via the foramen spinosum, where it attaches with the two roots of the auriculotemporal nerve. It deliverers blood to bones of the skull and also the dura mater.

Inferior alveolar artery:

The inferior alveolar artery is actually a facial artery that branches off from the maxillary artery. It starts close to the site where the maxillary artery emerges two of branches of the external carotid artery, which is situated at the top of the back of the jaw. It runs on the behalf of the lower jaw. In the rare situation, it may branch straightly from the external carotid artery on one behalf of the face, while situating normally on the other behalf.

Let’s go in deep, it composes three significant branches. The incisor branch moves from the incisor teeth to the mid of the jaw, where it joins into the incisor branch from the other behalf of the face. The mental branch then quits the lower jaw via an opening and feeds the chin. It further merges with the submental and inferior labial arteries. The mylohyoid branch carries blood flow to the mylohyoid muscle in the floor of the oral cavity.

It goes through the course of the inferior alveolar artery. This particular nerve is the primary part for dental anesthesia for procedures influencing the teeth of the lower jaw.

Accessory meningeal artery:

It is a branch that helps the mid of meningeal artery in delivering the dura mater of the brain.

Masseteric artery:

This narrow artery carries the blood flow to the masseter muscle of your jaw that makes easy in chewing of food.

Deep temporal artery:

This branch bifurcates into two – foremost and back, and course between the temporalis and the pericranium individually, supplying the blood to the muscles, and anastomose with the center worldly corridor. The foremost division links with the lacrimal vein by means for little branches which puncture the zygomatic bone and the wing of the sphenoid.

Buccal or buccinator artery:

It moves obliquely forward, in between the pterygoideus internus and also the insertion of the temporalis muscle, to the furnish surface of the buccinator muscles, to which it delivers, anastomosing with branches of the facial artery and with the infraorbital artery respectively. While, from the infraorbital area, the buccal artery fall bilaterally in the superficial face and approaches to outer margin of the nose, then running anti-parallel to the facial artery and finally proceed to lateral side.

 Artery of the pterygoid canal:

This artery goes into the pterygoid canal. It moves backward with the aid of the pterygoid canal with the corresponding nerve. It provides blood to the upper behalf of the pharynx (the portion of the alimentary canal immediately located just below the mouth cavity) and gives a small division into the tympanic nerve to the anastomose.
