# Human Anatomy: Male and Female Urinary and Reproductive Systems This document describes various structures of the male and female urinary and reproductive systems. The document consists of 24 images with labels indicating different anatomical parts. Here is a summary of all structures and their descriptions. ## Male Urinary and Reproductive System ### Urinary Structures **1) Vesica Urineria (Urinary bladder)** - The urinary bladder is a hollow, muscular organ located in the pelvis. - It stores urine produced by the kidneys before it is excreted from the body. **2) M. Detrusor Vesicae (Detrusor muscle)** - The detrusor muscle is the smooth muscle that forms the wall of the urinary bladder. - It is responsible for contracting to expel urine from the bladder. **3) Ostium Ureteris (Ureteral Opening)** - The orifices that allow urine to flow from the ureters into the bladder. **4) Plica Mucosa (Mucous fold)** - A fold in the mucous membrane that lines the urinary tract. - There are several mucous folds visible in the urinary bladder. **5) Plica Intersureterica (Intersureteric fold)** - A mucous fold located between the openings of the ureters in the urinary bladder. **6) Excavatio Rectovesica (Rectovesical pouch)** - A recess in the peritoneal cavity that lies between the rectum and the urinary bladder. **7) Spatium Prevesicale (Prevesical space)** - The space in front of the urinary bladder. ### Reproductive Structures **8) Ductus Deferens (Vas deferens)** - The muscular tube that carries sperm from the epididymis to the ejaculatory duct. **9) Ureter (Ureter)** - The tube that carries urine from the kidney to the urinary bladder. **10) Ampulla Ductus Deferentis (Ampulla of the vas deferens)** - A widening of the vas deferens before it joins the ejaculatory duct. **11) Vesiculae Seminales (Seminal vesicles)** - A pair of glands that secrete a fluid that contributes to semen. **12) Prostata (Prostate gland)** - A gland that surrounds the urethra and secretes a fluid that contributes to semen. **13) Ostium Urethrae Internum (Internal urethral opening)** - A small opening in the bladder which is the beginning of the urethra. **14) M. Sphincter Urethrae Internum (Internal urethral sphincter)** - A muscle that regulates the flow of urine from the urinary bladder to the urethra. **15) Ostium Urethrae Externum (External urethral opening)** - The opening at the end of the urethra where urine exits. **16) M. Sphincter Urethrae Externum (External urethral sphincter)** - A muscle that regulates the flow of urine from the urethra. **17) Pars Prostatica (Prostatic urethra)** - The section of the urethra that passes through the prostate gland. **18) Pars Membranacea (Membranous urethra)** - The short section of the urethra that passes through the pelvic floor. **19) Pars Spongiosa Urethrae (Spongy urethra)** - The longest section of the urethra, which passes through the penis. **20) Fossa Navicularis (Navicular fossa)** - The dilated, terminal part of the spongy urethra. **21) Pars Preprostatica (Preprostatic urethra)** - The short section of the urethra that is immediately before the part that is embedded in the prostate. **22) M. Transversus Perinei Profundus (Deep transverse perineal muscle)** - A muscle that contributes to the pelvic floor. **23) Plica Umbilicalis Mediana (Median umbilical fold)** - A fold in the peritoneum. **24) Ligamentum Umbilicale Mediana (Median umbilical ligament)** - A fibrous cord that is a remnant of the urachus in the umbilical cord. **25) Linea Alba (White line)** - A band of connective tissue in the midline of the abdominal wall. **26) Symphysis Pubis (Pubic symphysis)** - The joint between the two pubic bones. **27) Plica Umbilicalis Lateralis (Lateral umbilical fold)** - A fold of the peritoneum extending along the lateral parts of the peritoneal cavity. **28) Plica Umbilicalis Medialis (Medial umbilical fold)** - A fold of the peritoneum extending along the medial parts of the peritoneal cavity. **29) Fossa Inguinalis Medialis (Medial inguinal fossa)** - A depression in the inguinal region, which lies medial to the lateral inguinal fossa. **30) Fossa Inguinalis Lateralis (Lateral inguinal fossa)** - A depression in the inguinal region, which lies lateral to the medial inguinal fossa. **31) Fossa Supravesicale (Supravesical fossa)** - A depression in the peritoneal cavity that lies above the urinary bladder. ## Female Urinary and Reproductive System ### Urinary Structures **32) Excavatio Vesicouterina (Vesicouterine pouch)** - A recess in the peritoneal cavity that lies between the urinary bladder and the uterus. **33) Excavatio Recto-uterina (Rectouterine pouch of Douglas)** - A deep recess in the peritoneal cavity between the rectum and the uterus. **34) Spatium Prevesicale (Prevesical space)** - The space in front of the urinary bladder. ### Reproductive Structures **35) A. Vesica Superior (Superior vesical artery)** - An artery that supplies blood to the urinary bladder. **36) Vesicule Seminales (Seminal vesicles)** - A pair of glands that secrete a fluid that contributes to semen. **37) Ampulla Ductus Deferentis (Ampulla of the vas deferens)** - A widening of the vas deferens before it joins the ejaculatory duct. **38) Ligamentum Umbilicale Mediana (Median umbilical ligament)** - A fibrous cord that is a remnant of the urachus in the umbilical cord. **39) Ductus Deferens (Vas deferens)** - The muscular tube that carries sperm from the epididymis to the ejaculatory duct. **40) Ureter (Ureter)** - The tube that carries urine from the kidney to the urinary bladder. This document provides a detailed description of the male and female urinary and reproductive systems, including the location and function of each structure.
