1 Superficial temporal artery. A. temporalis superficialis. One of two terminal branches of the external carotid artery. It passes upward in front of the pinna accompanied by the auriculotemporal nerve. A B

2 Parotid branch. Ramus parotideus. It supplies the parotid gland. A

3 Transverse facial artery. A. transversa faciei (facialis). Branch that is covered by the parotid gland and passes below the zygomatic arch to the cheek. A

4 Anterior auricular branches. Rami auriculares anteriores. Several small branches to the pinna and the external acoustic meatus. A

5 Zygomatico-orbital artery. A. zygomatico-orbitalis. It passes above the zygomatic arch to the lateral margin of the orbit. A

6 Middle temporal artery. A. temporalis media. It passes above the zygomatic arch beneath the temporalis muscle. A

7 Frontal branch. Ramus frontalis. Anterior branch of superficial temporal artery. It anastomoses with its counterpart from the opposite side as well as with the supra-orbital and su-pratrochlear arteries from the internal carotid. A

8 Parietal branch. Ramus parietalis. Posterior branch of superficial temporal artery. It anastomoses with its counterpart from the opposite side as well as with the posterior auricular and occipital arteries. A

9 Maxillary artery. A. maxillaris. Larger terminal branch of external carotid artery. It arises beneath the temporomandibular joint, passes lateral or medial to the lateral pterygoid muscle and ramifies in the pterygopalatine fossa. A B

10 Deep auricular artery. A. auricularis profunda. It passes backward and upward to the temporo-mandibular joint, external acoustic meatus and tympanic membrane. B

11 Anterior tympanic artery. A. tympanica anterior. Accompanied by the chorda tympani, it passes through the petrotympanic fissure into the tympanic cavity. B

12 Inferior alveolar artery. A. alveolaris inferior. It passes between the medial pterygoid muscle and mandibular ramus into the mandibular canal up to the mental foramen. B

13 Dental rami. Rami dentales. Branches to roots of the teeth. B

13a Peridental branches. Rami peridentales.

14 Mylohyoid branch. Ramus mylohyoideus. Branch that exits in front of the mandibular canal and accompanies the mylohyoid nerve in the mylohyoid groove; it runs anteriorly beneath the mylohyoid muscle and anastomoses with the submental artery. B

15 Mental branch. Ramus mentalis. Terminal branch of inferior alveolar artery. It supplies the chin. B

16 Middle meningeal artery. A. meningea media. It passes medial to the lateral pterygoid muscle and through the foramen spinosum into the middle cranial fossa where it ramifies. B C

17 Accessory ramus. Ramus accessorius. Accessory branch from the middle meningeal artery or from the maxillary artery that extends to the adjacent muscles, the auditory tube and through the foramen ovale to the dura up to the trigeminal (semilunar) ganglion. B

18 Petrosal branch. Ramus petrosus. Small branch that arises directly after the entrance of the middle meningeal artery into the cranial cavity and anastomoses with the stylomastoid artery via the hiatus of the canal for the greater petrosal nerve. C

19 Superior tympanic artery. A. tympanica superior. It arises close to the petrosal branch and passes into the tympanic cavity with the lesser petrosal nerve. C

20 Frontal branch. Ramus frontalis. Anterior, large terminal branch in the cranium. It lies in a bony groove often closed to form a canal. C

21 Parietal branch. Ramus parietalis. Terminal branch passing to the posterior half of the cranium. C

22 Orbital branch. Ramus orbitalis. It runs through the superior orbital fissure in the direction of the lacrimal gland. C

23 Anastomotic branch connecting the orbital branch and the lacrimal artery. Ramus anas-tomoticus [[cum a. lacrimalis]]. C

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
