EDP 363 1st Edition Lecture 10 Outline of Last Lecture I. Alfred Kinsey II. Masters and JohnsonIII. Random InfoIV. Facts About youV. Genital DevelopmentVI. Adult Male GenitalsOutline of Current Lecture I. Adult Male Genitals continuedII. Circumcision III. Female AnatomyCurrent LectureI. Adult Male Genitals continueda. Prostate glandi. Produces spermii. Opening to male urethra tube (allows sperm to exit body)iii. Opening to male bladder1. Muscle at base closes keeping the semen from exiting hereb. Semen –alkali fluid i. Semen is pH 7.2-7.6 (a base)1. Bases don’t like acids; the vagina is acidic  sperm dies quicklyii. Sperm make up 1% of fluid, the rest is alkali fluidiii. Average ejaculate: 400-500 million spermiv. 1,000 sperm are created per heart beatv. Sperm last 30 days in testes, then diec. Male Shafi. 3 chambers (2 on top and one on the bottom middle)ii. full of specialized cells that can absorb blood  expansion (erection)1. Head of the penis also has some of these cells, although not as manyiii. Empty tube where urethra comes out of the bodyiv. Urethra tube surrounded by these blood absorbing cellsv. Bundle of nerves at the base (frenulum)  connects head to shaf1. Extremely sensitive to pleasureThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.vi. Opening at head  urethra tube exitsII. Circumcisiona. Coving of the penis (hood) is same as female clitoral hood b. *Couperus gland at base of urethra produces alkali fluid when penis is aroused. Clear fluid can be emitted at any time during arousal.c. Foreskin is raised and covering is cute (but the frenulum nerves are NOT cut!)III. Female Anatomya. Mums pubis areai. Pressure nerve endingsii. Connected to the clitoris (which sits right below it)b. Urethra opening/Vaginal opening (hymen)i. At least partially covered when born. Important during development as it blocks bacteria.ii. Broken when virginity is lost1. Tampons2. Gymnastics3. Biking and horseback riding4. Fingerc. Base  Anus (perineum)i. Doctors may cut it during child birth to avoid tearing.d. INSIDE:i. 2 walls lie flat against each other, tilted 45 degrees to outside of the body (upwards tilt).1. Cells produce in an acidic environment2. Self clean3. No top (uterus serves as the top, sits on top and held in place by muscles)a. Bottom of uterus = cervixi. Hole in cervix = osii. Os (hole in cervix)1. Allows baby to exit uterus2. Menstrual flow exits uterus  vagina3. Allows sperm entry into uterus to fallopian tubes iii. Uterus is tilted forward at a 90% angle1. Mio mabrium: elastic muscles allowing expansion2. Endometrium lining: specialized cells sensitive to estrogen and progestin, which make it expand and fill with nutrients for pregnancya. Sluffs off during menstruation (comes through os to vagina)iv. The end of uterus has 2 wings, fallopian tubes1. Surround ovaries, which produce eggs and contain between 200,000-400,000 egg folicals2. Has all eggs at birth3. 200-400 eggs ripen/mature each montha. The first to mature sends a message to the others, telling them not to continue maturing.b. That egg ovulates (the maturing and leaving of the egg from the ovaries into the fallopian tubes)c. 5 days for egg to travel length of fallopian tubed. Egg lives 1-2 days (not long enough to get to uterus unless it fertilizes; deteriorates in the fallopian tube)e. Egg can ONLY be fertilized in the fallopian tubesf. Fertilization  cells start
