What separates the paravesical space from the pararectal space?

The pararectal and paravesical spaces are divided by the uterine artery. The boundaries of the pararectal space are the uterine artery (anterior), internal iliac artery (lateral), and the ureter (medial). The limit of dissection for the medial paravesical space is the floor formed by the levator ani muscle.

What is the Vesicovaginal space?

12.1) The space is bounded ventrally by the bladder, laterally by the bladder pillars and dorsally by the vagina. Superiorly, it ends at the point of fusion between the adventitia of the bladder and vagina (loose connective tissue), which is called vesicocervical ligament or supravaginal septum.

What are the pelvic spaces?

The pelvic peritoneal space is the inferior reflection of the peritoneum over the fundus of the urinary bladder and the front of the rectum at the junction of its middle and lower thirds. In females, the reflection is also over the anterior and posterior surface of the uterus and the upper posterior vagina.

What is the Parametrium?

The fat and connective tissue that surrounds the uterus. The parametrium helps connect the uterus to other tissues in the pelvis.

What organs are in retroperitoneal space?

Anatomy. The retroperitoneal space is bounded by the posterior parietal peritoneum anteriorly and the lumbar spine posteriorly. The retroperitoneal space contains the kidneys, adrenal glands, pancreas, nerve roots, lymph nodes, abdominal aorta, and inferior vena cava.

How do you enter retroperitoneal space?

The round ligament is the key to exposing the retroperitoneal space. It should be open at the pelvic sidewall, just medial to the external iliac vessels. The umbilical ligament can be used as a landmark. The divided round ligament is retracted ventrally and medially to place the ovarian vessels under traction.

Which organs are located in the pelvic cavity?

The pelvic cavity is a funnel-shaped space surrounded by pelvic bones and it contains organs, such as the urinary bladder, rectum, and pelvic genitals, to name a few. The pelvic cavity and the abdominal cavity together form the larger abdominopelvic cavity.

Are the kidneys in the pelvic cavity?

Anatomical terminology The abdominopelvic cavity is a body cavity that consists of the abdominal cavity and the pelvic cavity. It contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, and most of the small and large intestines. It also contains the urinary bladder and internal reproductive organs.

What are the 3 layers of uterus?

The thick wall of the uterus has 3 layers:

• The endometrium is the inner layer that lines the uterus. It is made up of glandular cells that make secretions.
• The myometrium is the middle and thickest layer of the uterus wall. It is made up mostly of smooth muscle.
• The perimetrium is the outer serous layer of the uterus.

Where is the paravesical space located in the human body?

The paravesical space is the retroperitoneal space that lies lateral to the urinary bladder and anterior and superior to the pararectal space. It is enclosed medially by the bladder, laterally by the pelvic walls, and inferiorly by the uterine artery (Fig. 7).

What are the avascular spaces of the female?

Moreover, new spaces and surgical planes have been developed after the adoption of laparoscopy and nerve-sparing gynecological procedures. Avascular spaces are useful anatomical landmarks in retroperitoneal anatomic and pelvic surgery for both malignant and benign conditions.

Is the avascular space filled with areolar connective tissue?

The term “spaces” refers to the areas delimited by at least two independent fasciae and filled with areolar connective tissue. However, there is discrepancy regarding the spaces and their limits between clinical anatomy and gynecologic surgery, as not every avascular space described in literature is delimited by at least two fasciae.
