    BASIC SCIENCE identify the rectosigmoid junction with confidence at operation. The anatomy of the rectum The rectosigmoid junction usually lies approximately 6 cm below the level of the sacral promontory. Approached from the distal and anal canal end, however, as when performing a rigid or flexible sigmoid- oscopy, the rectosigmoid junction is seen to be 14e18 cm from Vishy Mahadevan the anal verge, and 18 cm is usually taken as the measurement for audit purposes. The rectum in the adult measures 10e14 cm in length.

Introduction • The female reproductive system is more complex than the male system because it serves more purposes – Produces and delivers gametes – Provides nutrition and safe harbor for fetal development – Gives birth – Nourishes infant • Female system is more cyclic, and the hormones are secreted in a more complex sequence than the relatively steady secretion in the male 28-2 Sexual Differentiation • The two sexes indistinguishable for first 8 to 10 weeks of development • Female reproductive tract develops from the paramesonephric ducts – Not because of the positive action of any hormone – Because of the absence of testosterone and müllerian-inhibiting factor (MIF) 28-3 Reproductive Anatomy • Expected Learning Outcomes – Describe the structure of the ovary – Trace the female reproductive tract and describe the gross anatomy and histology of each organ – Identify the ligaments that support the female reproductive organs – Describe the blood supply to the female reproductive tract – Identify the external genitalia of the female – Describe the structure of the nonlactating breast 28-4 Sexual Differentiation • Without testosterone: – Causes mesonephric ducts to degenerate – Genital tubercle becomes the glans clitoris – Urogenital folds become the labia minora – Labioscrotal folds

Objectives At the end of the lecture, the student should be able to describe the: ✓ Boundaries of the perineum. ✓ Division of perineum into two triangles. ✓ Boundaries & Contents of anal & urogenital triangles. ✓ Lower part of Anal canal. ✓ Boundaries & contents of Ischiorectal fossa. ✓ Innervation, Blood supply and lymphatic drainage of perineum. Lecture Outline ‰ Introduction: • The trunk is divided into 4 main cavities: thoracic, abdominal, pelvic, and perineal. (see image 1) • The pelvis has an inlet and an outlet. (see image 2) The lowest part of the pelvic outlet is the perineum. • The perineum is separated from the pelvic cavity superiorly by the pelvic floor. • The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus muscle, and associated connective tissue. (see image 3) We will talk about them more in the next lecture. Image (1) Image (2) Image (3) Note: this image is seen from ABOVE Perineum (In this lecture the boundaries and relations are important) o Perineum is the region of the body below the pelvic diaphragm (The outlet of the pelvis) o It is a diamond shaped area between the thighs.

Abdominal wall and the pelvis 2- Visceral peritoneum - covers the viscera 3- Peritoneal cavity - the potential space between the parietal and visceral layer of peritoneum - in male, is a closed sac - but in the female, there is a communication with the exterior through the uterine tubes, the uterus, and the vagina ▪ Peritoneum cavity divided into Greater sac Lesser sac Communication between them by the epiploic foramen The peritoneum The peritoneal cavity is the largest one in the body. Divided into tow sac : .Greater sac; extends from diaphragm down to the pelvis. Lesser Sac .Lesser sac or omental bursa; lies behind the stomach. .Both cavities are interconnected through the epiploic foramen(winslow ). .In male : the peritoneum is a closed sac . .In female : the sac is not completely closed because it Greater Sac communicates with the exterior through the uterine tubes, uterus and vagina. Peritoneum in transverse section The relationship between viscera and peritoneum Intraperitoneal viscera viscera is almost totally covered with visceral peritoneum example, stomach, 1st & last inch of duodenum, jejunum, ileum, cecum, vermiform appendix, transverse and sigmoid colons, spleen and ovary Intraperitoneal viscera Interperitoneal viscera Retroperitoneal viscera Interperitoneal viscera Such organs are not completely wrapped by peritoneum one surface attached to the abdominal walls or other organs. Example liver, gallbladder, urinary bladder and uterus Upper part of the rectum, Ascending and Descending colon Retroperitoneal viscera some organs lie on the posterior abdominal wall Behind the peritoneum they are partially covered by peritoneum on their anterior surfaces only Example kidney, suprarenal gland, pancreas, upper 3rd of rectum duodenum, and ureter, aorta and I.V.C The Peritoneal Reflection The peritoneal reflection include: omentum, mesenteries, ligaments, folds, recesses, pouches and fossae.

  • Inguinofemoral Area

    Inguinofemoral Area

    Inguinofemoral Area Inguinal Canal Anatomy of the Inguinal Canal in Infants and Children There are readily apparent differences between the inguinal canals of infants and adults. In infants, the canal is short (1 to 1.5 cm), and the internal and external rings are nearly superimposed upon one another. Scarpa's fascia is so well developed that the surgeon may mistake it for the aponeurosis of the external oblique muscle, resulting in treating a superficial ectopic testicle as an inguinal cryptorchidism. There also may be a layer of fat between the fascia and the aponeurosis. We remind surgeons of the statement of White that the external oblique fascia has not been reached as long as fat is encountered. In a newborn with an indirect inguinal hernia, there is nothing wrong with the posterior wall of the inguinal canal. Removal of the sac, therefore, is the only justifiable procedure. However, it is extremely difficult to estimate the weakness of the newborn's posterior inguinal wall by palpation. If a defect is suspected, a few interrupted permanent sutures might be used to perform the repair. Adult Anatomy of the Inguinal Canal The inguinal canal in the adult is an oblique rift in the lower part of the anterior abdominal wall. It measures approximately 4 cm in length. It is located 2 to 4 cm above the inguinal ligament, between the opening of the external (superficial) and internal (deep) inguinal rings. The boundaries of the inguinal canal are as follows: Anterior: The anterior boundary is the aponeurosis of the external oblique muscle and, more laterally, the internal oblique muscle.
