274 HUMAN ANATOMY. 



Muscular coat, about one-half inch thick, composed of un- 

 striped muscular fibres arranged into three layers; 



Mucous coat, has numerous tubular follicles., is lined with 

 ciliated columnar epithelium, and has no submucous coat to con- 

 nect it with the muscular coat. 



The mucous membrane of the cervix is thrown into folds, or 

 rugce, which assume on the anterior and posterior walls a 

 branched arrangement, or arbor vitce uterina. It is lined by 

 squamous epithelium, and presents numerous follicular glands 

 the ovula of Nabotli, or glandulce Nabothi. 



The arteries are branches of the ovarian from the aorta, 

 and the uterine from the internal iliac, remarkable for their 

 tortuosity and anastomoses. 



The veins form plexuses or uterine sinuses, the branches of 

 which correspond to the uterine arteries and terminate in the 

 uterine plexuses. 



The lymphatics are very numerous and terminate in the 

 lumbar and pelvic glands. 



The nerves are from the ovarian and hypogastric plexuses 

 of the sympathetic. 



The ligaments of the uterus are folds of peritoneum ar- 

 ranged into four pairs : 



Two anterior, or vcxiro-utcrine, passing one on either side from the 

 posterior surface to the cervix uteri; 



Two posterior or rccto-ntfrinc, passing between the sides of the 

 rectum and uterus, and inclosing a cul-dc-sac, the recto-vaginal p'ntcJi, 

 or Douglas' poucJt ; 



A prolongation of this ligament upward to the second sacral verte- 

 bra, with some unstriated muscular fibres derived from the uterus and 

 vagina, forms the so-called utero-sacral I hutments; 



Two lateral, or broad, extending from the uterus to the sides of 

 the pelvis, dividing it into two portions, and inclosing the Fallopian 

 tubes, ovary, ovarian ligament, uterine blood-vessels, lymphatics, and 

 nerves, and some unstriated muscular fibres ; 



Two round ligaments, are cords of unstriated muscular and fibrous 

 tissue, extending from the side of the fundus uteri to the inguinal canal, 

 where it is lost in the subcutaneous tissue of the pubes. 



The canal of Nuck, a pouch of peritoneum, incloses the ligament in 

 the young subject, but is usually obliterated later. 



THE OVARIES correspond to the male testicles, and are sus- 

 pended behind the broad ligament inclosed in its posterior layer. 



They are largest from puberty to adult age, and measure 

 one and one-half inches in length, three-quarters of an inch in 

 width, and one-third of an inch in thickness, and weigh from 

 one to two drachms. The inner border is attached to the fundus 

 uteri by the ovarian ligament, and its outer border to the fim-
