Reproductive System Reference Sheet 3: GLOSSARY Anus – The opening in the buttocks from which bowel movements come when a person goes to the bathroom. It is part of the digestive system; it gets rid of body wastes. Buttocks – The medical word for a person’s “bottom” or “rear end.” Cervix – The opening of the uterus into the vagina. Circumcision – An operation to remove the foreskin from the penis. Cowper’s Glands – Glands on either side of the urethra that make a discharge which lines the urethra when a man gets an erection, making it less acid-like to protect the sperm. Clitoris – The part of the female genitals that’s full of nerves and becomes erect. It has a glans and a shaft like the penis, but only its glans is on the out side of the body, and it’s much smaller. Discharge – Liquid. Urine and semen are kinds of discharge, but the word is usually used to describe either the normal wetness of the vagina or the abnormal wetness that may come from an infection in the penis or vagina. Duct – Tube, the fallopian tubes may be called oviducts, because they are the path for an ovum.

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. Boundaries: (these are the external or surface boundaries) Anteriorly Laterally Posteriorly Medial surfaces of Intergluteal folds Mons pubis the thighs or cleft Contents: 1. Lower ends of urethra, vagina & anal canal 2. External genitalia 3. Perineal body & Anococcygeal body Extra (we will now talk about these in the next slides) Perineum Extra explanation: The perineal body is an irregular Perineal body fibromuscular mass.

Lab #23 Anal Triangle
THE BONY PELVIS AND ANAL TRIANGLE (Grant's Dissector [16th Ed.] pp. 141-145) TODAY’S GOALS: 1. Identify relevant bony features/landmarks on skeletal materials or pelvic models. 2. Identify the sacrotuberous and sacrospinous ligaments. 3. Describe the organization and divisions of the perineum into two triangles: anal triangle and urogenital triangle 4. Dissect the ischiorectal (ischioanal) fossa and define its boundaries. 5. Identify the inferior rectal nerve and artery, the pudendal (Alcock’s) canal and the external anal sphincter. DISSECTION NOTES: The perineum is the diamond-shaped area between the upper thighs and below the inferior pelvic aperture and pelvic diaphragm. It is divided anatomically into 2 triangles: the anal triangle and the urogenital (UG) triangle (Dissector p. 142, Fig. 5.2). The anal triangle is bounded by the tip of the coccyx, sacrotuberous ligaments, and a line connecting the right and left ischial tuberosities. It contains the anal canal, which pierced the levator ani muscle portion of the pelvic diaphragm. The urogenital triangle is bounded by the ischiopubic rami to the inferior surface of the pubic symphysis and a line connecting the right and left ischial tuberosities. This triangular space contains the urogenital (UG) diaphragm that transmits the urethra (in male) and urethra and vagina (in female). A. Anal Triangle Turn the cadaver into the prone position. Make skin incisions as on page 144, Fig. 5.4 of the Dissector. Reflect skin and superficial fascia of the gluteal region in one flap to expose the large gluteus maximus muscle. This muscle has proximal attachments to the posteromedial surface of the ilium, posterior surfaces of the sacrum and coccyx, and the sacrotuberous ligament.

MD-17 , CONTENTS THE URINARY SYSTEM 4 THE REPRODUCTIVE SYSTEM 5 The Scrotum The Testis The Epididylnis The Ductus Deferens The Ejaculatory Duct The Seminal Vesicle The Spermatic Cord The Penis The Prostate Gland THE INGUINAL CANAL l) HERNIAS FURTIlER READING 10 MODEL KEY 1I Human Male Pelvis This life-size model shows the viscera and structures which form the urogenital system and some of the related anatomy such as the sig moid colon and rectum. The vascular supply to the viscera and support ing tissue is demonstrated, as well as that portion of the vascular system which continues into the lower extremity. The model is divided into right and left portions. The right portion shows a midsagittal section of the pelvic structures. The left represents a similar section, but the dissection is deeper. Two pieces are remov able on the left side; one piece includes the bladder, prostate, and semi nal vesicles, and the other includes the penis, left testicle, and scrotum. When all portions are removed, a deeper view of these structures and a deeper dissection of the pelvis can be seen. THE URINARY SYSTEM The portion of the urinary system shown depicts the ureter from the level of the 5th lumbar vertebra, where it passes the common iliac ar tery near the bifurcation of thi s artery into the external and internal iliac arteries. The ureter then passes toward the posterior portion of the bladder, beneath the vas deferens, and opens through the wall of the blad der at one cranial corner of the trigone on the bladder's interior.
