Copyright © The McGraw-Hill Companies, Inc. Permission required for reproduction or display. 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 -

After a “breaking‐in” period, the pain‐to‐numbness ratio becomes favourable. As long as you protect against infection, wear padded shorts with a generous layer of chamois cream, no underwear and make regular offerings to the ingrown hair goddess, things are manageable.

Color Code Important Female Perineum Doctors Notes Notes/Extra explanation Please view our Editing File before studying this lecture to check for any changes. 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.

Microlymphatic Surgery for the Treatment of Iatrogenic Lymphedema

Chen, MDb, Marc Riquet, MDc KEYWORDS Lymphedema Treatment Autologous lymph node transplantation (ALNT) Microsurgical vascularized lymph node transfer Iatrogenic Secondary Brachial plexus neuropathy Infection KEY POINTS Autologous lymph node transplant or microsurgical vascularized lymph node transfer (ALNT) is a surgical treatment option for lymphedema, which brings vascularized, VEGF-C producing tissue into the previously operated field to promote lymphangiogenesis and bridge the distal obstructed lymphatic system with the proximal lymphatic system. Additionally, lymph nodes with important immunologic function are brought into the fibrotic and damaged tissue. ALNT can cure lymphedema, reduce the risk of infection and cellulitis, and improve brachial plexus neuropathies. ALNT can also be combined with breast reconstruction flaps to be an elegant treatment for a breast cancer patient.

MR Imaging of Vaginal Morphology, Paravaginal Attachments and Ligaments
MR imaging of vaginal morph:ingynious 05/06/15 10:09 Pagina 53 Original article MR imaging of vaginal morphology, paravaginal attachments and ligaments. Normal features VITTORIO PILONI Iniziativa Medica, Diagnostic Imaging Centre, Monselice (Padova), Italy Abstract: Aim: To define the MR appearance of the intact vaginal and paravaginal anatomy. Method: the pelvic MR examinations achieved with external coil of 25 nulliparous women (group A), mean age 31.3 range 28-35 years without pelvic floor dysfunctions, were compared with those of 8 women who had cesarean delivery (group B), mean age 34.1 range 31-40 years, for evidence of (a) vaginal morphology, length and axis inclination; (b) perineal body’s position with respect to the hymen plane; and (c) visibility of paravaginal attachments and lig- aments. Results: in both groups, axial MR images showed that the upper vagina had an horizontal, linear shape in over 91%; the middle vagi- na an H-shape or W-shape in 74% and 26%, respectively; and the lower vagina a U-shape in 82% of cases. Vaginal length, axis inclination and distance of perineal body to the hymen were not significantly different between the two groups (mean ± SD 77.3 ± 3.2 mm vs 74.3 ± 5.2 mm; 70.1 ± 4.8 degrees vs 74.04 ± 1.6 degrees; and +3.2 ± 2.4 mm vs + 2.4 ± 1.8 mm, in group A and B, respectively, P > 0.05). Overall, the lower third vaginal morphology was the less easily identifiable structure (visibility score, 2); the uterosacral ligaments and the parau- rethral ligaments were the most frequently depicted attachments (visibility score, 3 and 4, respectively); the distance of the perineal body to the hymen was the most consistent reference landmark (mean +3 mm, range -2 to + 5 mm, visibility score 4). -

The bilateral major vestibular glands, better known as Bartholin’s glands, are situated at about the four and eight o’clock positions on the vulva and vary in size from 1 to 10 cm. These glands contain a clear and sometimes mucoid material and mucinous cysts are caused by a blockage in a gland’s duct. -

Uterine Tubes • Also called Fallopian Tubes or Oviducts • Open-ended, muscular tube lined with secretory cells and ciliated cells that sweep secretions and peritoneal fluid towards the uterus. • Uterine Tube Regions: – narrow isthmus near the uterus – middle portion is the ampulla – flared distally into infundibulum with fimbriae • Fertilization usually occurs in ampulla or isthmus Epithelium lining the uterine tube consists of ciliated cells, goblet cells and other secretory cells.
