15 Pubic branch. Ramus pubicus. It anastomoses with the obturator branch of the inferior epigastric artery [[corona mortis]]. C

16 Acetabular branch. Ramus acetabularis. It passes through the acetabular notch to the ligament for the head of the femur. B

17 Anterior branch. Ramus anterior. Located on the adductor brevis; it anastomoses with the medial circumflex femoral artery. B

18 Posterior branch. Ramus posterior. It is located beneath the adductor brevis. B

19 Superior gluteal artery. A. glutealis superior. It traverses the greater sciatic foramen above the piriformis [[suprapiriform foramen]] to enter the gluteal region. A C

20 Superficial branch. Ramus superficialis. It lies between the gluteus maximus and medius and anastomoses with the inferior gluteal artery. A

21 Deep branch. Ramus profundus. It lies between the gluteus medius and minimus. A

22 Superior branch. Ramus superior. It runs along the upper margin of the gluteus minimus as far as the tensor fasciae latae. A

23 Inferior branch. Ramus inferior. It courses in the gluteus medius as far as the greater trochanter. A

24 Inferior gluteal artery. A. glutealis inferior. Emerges through the greater sciatic foramen below the piriformis muscle [[infrapiriform foramen]]; its branches are distributed beneath the gluteus maximus. They anastomose with the superior gluteal, obturator and circumflex femoral arteries. A C

25 Accompanying artery of sciatic nerve (sciatic artery). A. comitans n. ischiadici (sciatici). Phylogenetically speaking, the major artery of the leg. It accompanies and supplies the sciatic nerve and anastomoses with the medial circumflex femoral artery and perforating branches. A C

26 Umbilical artery. A. umbilicalis. First inferior branch ofthe internal iliac artery. After birth, it becomes obliterated beyond the exit of the superior vesical arteries. C

26 a Patent part. Pars patens. Portion of the fetal umbilical artery which does not become obliterated postnatally. It gives off the vessels listed below.

27 Artery ofductus deferens. A. ductus deferentis. It descends in the pelvis up to the base of the bladder. From there downward, it accompanies the ductus deferens to eventually anastomose with the testicular artery. C

28 Ureteric branches. Rami ureterici. Three branches that supply the ureter. C

29 Superior vesical arteries. Aa. vesicales superiores. Arteries to the upper and middle segments of the urinary bladder. C

29 a Occluded part. Pars occlusa. Portion of the fetal umbilical artery which becomes obliterated postnatally and forms the medial umbilical ligament.

30 Medial umbilical ligament. Ligamentum umbilicale mediale [[laterale]]. Fibrous cord remnant of the umbilical artery occupying the medial umbilical fold. C

1 Inferior vesical artery. A. vesicalis inferior. It supplies the inferior part of the urinary bladder and, in males, the prostate and seminal vesicle. A

1a Prostatic branches. Rami prostatici. Branches that supply the prostate and seminal vesicle.

2 Uterine artery. A. uterina. It corresponds to the artery of the ductus deferens. It passes to the cervix within the base of the broad ligament and very tortuously ascends lateral to the uterus. A C

2 a Helicine branches. Rami helicini. Corkscrewlike, coiled terminal branches of the uterine artery. C

3 Vaginal branches (azygos arteries of vagina). Rami vaginales (aa. azygoi vaginae). Branches to the cervix that anastomose with vessels on the oposite side to supply the upper part of the vagina. A C

4 Ovarian branch. Ramus ovaricus. It runs along the ovarian ligament proper and through the me-sovarium to the ovary. It anastomoses with the ovarian artery and the tubal branch of the uterine artery. C

5 Tubal branch. Ramus tubarius (tubalis). It runs in the mesosalpinx of the tube to the point where it anastomoses with the ovarian artery. C

6 Vaginal artery. A. vaginalis. It arises directly from the internal iliac artery. A

7 Middle rectal artery. A. rectalis media. It crosses the floor of the pelvis to the rectum and supplies the retal muscles. A E

7a Vaginal branches. [Rami vaginales]. Branches to the lower part of the vagina. A

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.
