The Female Internal Genital Organs

 

The Vagina

The Relations of the Vagina

Back to top

The Sphincters of the Vagina

  1. The pubovaginalis muscle, the anterior part of the levator ani;
  2. The urogenital diaphragm;
  3. And the bulbospongiosus muscle.

 

The Arterial Supply of the Vagina

 

The Venous Drainage of the Vagina

 

The Lymphatic Drainage of the Vagina

  1. Those from the superior part accompany the uterine artery and drain into the internal and external iliac lymph nodes;
  2. Those from the middle part accompany the vaginal artery and drain into the internal iliac lymph nodes;
  3. And those from the vestibule drain into the superficial inguinal lymph nodes.

The Uterus

  1. The expanded superior 2/3 is known as the body;
  2. The cylindrical inferior 1/3 is called the cervix (L. neck).

 

The Fundus of the Uterus

 

The Cervix of the Uterus

 

The Isthmus of the Uterus

The Wall of the Uterus

  1. The outer serous coat called the perimetrium, consists of peritoneum supported by a thin layer of connective tissue;
  2. The middle muscular coat called the myometrium consists of 12 to 15 mm of smooth muscle. The myometrium increases greatly during pregnancy. The main branches of the blood vessels and nerves of the uterus are located in this layer;
  3. The inner mucous coat called endometrium is firmly adherent to the underlying myometrium.

Arterial Supply of the Uterus

 

Venous Drainage of the Uterus

 

Lymphatic Drainage of the Uterus

  1. Most lymph vessels from the fundus pass with the ovarian vessels to the aortic lymph nodes, but some lymph vessels pass to the external iliac lymph nodes or run along the round ligament of the uterus to the superficial inguinal lymph nodes.
  2. Lymph vessels from the body pass through the broad ligament to the external iliac lymph nodes.
  3. Lymph vessels from the cervix pass to the internal iliac and sacral lymph nodes.
