The Kidneys These are two bean shaped kidneys in the body, one on either side, located near the middle of the back behind the 13th rib. These 5 – 6 inch long organs are responsible for processing waste products and filtering the blood to ensure that the body is in a state of balance. The waste comes from the normal breakdown from the food that is eaten. The Wiltshire School of Beauty and Holistic Therapy Certificate of Merit in Anatomy and Physiology© It is essential that this waste is removed as it could damage the body. Each kidney is joined to the aorta, which is the largest artery in the body by a short renal artery, as they receive a huge blood supply. Each kidney contains around a million nephrons, a tube which is closed at one end, and open at the other.

FEMALE PHYSIOLOGY EXTERNAL GENITALIA AND SECONDARY SEX CHARACTERISTICS PUBIC HAIR: A triangular mass of hair covering the mons pubis. The amount of and thickness of the pubic hair varies from person to person. MONS PUBIS: A fatty pad at the top of the vulva; covered with pubic hair and susceptible to sexual stimulus. VULVA: The word comes from the Latin root “covering”. The vulva is not one specific organ, but a collection of genital structures. OUTER LIPS (Labia Majora) a. The outermost hair-covered folds of skin surrounding the genitals. b. They vary greatly in size. c. Like the scrotum, the outer lips swell slightly with stimulation; in their stimulated state they pull back and expose the Inner Lips. INNER LIPS (Labia Minora) a) This is the second covering of the vaginal opening; they enclose the vaginal and urethral opening. b) They are a thin, moist, sensitive fold of skin containing many erotic nerve endings and blood vessels. c) They contain the same tissue as the shaft of the penis; as a result they too swell with sexual stimulus. CLITORIS a) This is the most sexually sensitive part of the female body. It corresponds to the glans or head of the penis. b) Though there is no reproductive purpose, the clitoris is made of erectile tissue and contains a high concentration of erotic neural receptors and blood vessels.

Further Reading
1 HYPOTHALAMUS PITUITARY GONADAL AXIS Lecture One Further Reading Female Menstrual Cycle (the cycle will be discussed in the next lecture, in a somewhat less detailed manner) - The primary female reproductive organ are the ovaries, an almond-shaped organ in the lower abdomen. - The ovaries produce eggs or the ovum, the functional unit of the ovaries are the follicles. Females are born with immature follicles called “primordial follicles”, a follicle of this type consists of a primary oocyte (an immature ovum), surrounded by a relatively flat layer of epithelium, these epithelial cells are known as “granulosa cells”. - Follicles remain immature in the primordial stage throughout childhood, but then suddenly are triggered into maturity during puberty due to the sudden rise in GnRH (GnRH secretion remains low throughout childhood but increases in late childhood to trigger puberty) with subsequent rise in FSH and LH. - Puberty immediately triggers the the menstrual cycle, which lasts for 28 days monthly, and are divided into two subcycles, an ovarian cycle (which we will discuss), and a uterine cycle (discussed in lecture three, involves menstrual blood). However these cycles occur simultaneously, don’t worry, all will be clear by the next lecture. - Ovulation occurs at day 14 of this cycle. (all days mentioned subsequently are approximations) - Usually only 6-12 follicles participate in menstrual cycles, with only one follicle releasing its ovum to be fertilized. - The ovaries contain around 300-500 thousand follicles, 6-12 of which are usually responsive to participate in the menstrual cycle each month, with only one follicle releasing its ovum and the remaining follicles simply degenerate.

Cell Division, Gametogenesis & Theory of Ovulation
CELL DIVISION, GAMETOGENESIS & THEORY OF OVULATION Cell Cycle • The cell cycle is the series of events that take place in the cell leading to its division and duplication that produces two daughter cells. • Periods of cell cycle: • Interphase • Cell division • Cytokinesis Interphase • It is also called the Interkinesis / Resting phase. • During this stage, the nucleus is not dividing but the DNA in the nucleus is duplicated in preparation for the next division. • Phases of interphase: • Gap 0 (G0) • Gap 1 (G1) • Synthesis (S) • Gap 2 (G2) • Gap 1(G1) • The cell grows and functions normally. • A high amount of protein synthesis occurs and the cell grows to double its original size. • More organelles are produced. • The volume of cytoplasm increases and mitochondria and chloroplasts divide. • If the cell is not to divide again, it will enter G0. • Synthesis (S) • The cell duplicates its DNA. • This is also known as The Swanson Phase. • Gap 2 (G2) • The cell resumes its growth in preparation for division. • Gap Zero (G0) • Some cells do not further divided means their cell cycle is arrested so it is termed as Gap Zero (G0). Cell Division • Cell division is the process by which a parent cell divides into two or more daughter cells. • Eukaryotes undergo two type of cell division : • Mitotis • Meiosis • Prokaryotes undergo cell division : • Binary fission Mitosis (Karyokinesis) • It is the process in which the parental cell divides into two daughter cells which are genetically identical to the parent cell. • All somatic (body) cells multiply by the mitosis cell division. • Stages of Mitosis: 1.

Unit 4 Lecture 12
Unit 4 Lecture 12 Unit 4 Lecture 12 THE REPRODUCTIVE SYSTEM Reproduction is the process by which a species continues to survive. Genetic material is passed from one generation to the next through sexual reproduction. Offspring have a combination of genes from both patents. The primary reproductive organs are called gonads because they produce gametes (sperm cells in the male and ova in the female). Gonads also produce hormones. In addition to the primary sex organs are the secondary sex organs which transport, store the gametes, and accessory glands that produce materials that support the gametes. Male Reproductive System The function of the male reproductive system is to produce the sex steroid testosterone, to produce sperm (process is called spermatogenesis), and to deliver sperm to the female vagina. The testes (testicles) are a pair of oval glands located in the scrotum and are divided into 200-300 compartments called lobules by the tunica albuginea. Each tubule contains 1-3 seminiferous tubules. The seminiferous tubules produce: sperm cells, sustentacular (Sertoli) cells that support, protect, and nourish sperm cells and secrete inhibin (a hormone that helps regulate sperm production by inhibiting FSH), and Interstitial cells (cells of Leydig) which secrete testosterone. Spermatogenesis is an ongoing process by which sperm are made and the chromosome number is reduced to (n) or the haploid number of chromosomes. Humans have 23 pairs or 46 chromosomes. Twenty-two pairs are homologous and are called autosomes. One pair (XY) is called the sex chromosomes and this chromosome determines the sex of the individual. Any individual having a Y chromosome is considered male.

Mayci Fullmer Dr. Oliver Oakley, Department of Biological Sciences Abstract Histology is the study of microscopic tissue structures that examines the correlation between structure and function. This technique was utilized when analyzing the biological processes of folliculogenesis and oogenesis. These processes study the maturation of the ovarian follicle and production of an ovum, respectively. The p75 neurotrophin receptor (p75NTR) has been identified to contribute to the maturation of ovarian follicles, but the role of p75NTR in ovulation remains unknown. To investigate the role of p75NTR in ovulation, an animal study analyzing the histology of the mouse ovary was conducted.

Lecture Outline
Biology 218 – Human Anatomy RIDDELL Chapter 27 Adapted form Tortora 10th ed. LECTURE OUTLINE A. Introduction (p. 835) 1. Sexual reproduction is the process by which organisms produce offspring by means of germ cells called gametes; when a male gamete unites with a female gamete during fertilization, the resulting cell contains one set of chromosomes from each parent. 2. The organs of the reproductive systems may be grouped by function: i. gonads produce gametes and secrete sex hormones a. testes produce sperm cells b. ovaries produce ova ii. ducts receive, store, and transport gametes iii. accessory sex glands produce substances that protect gametes and facilitate their movement iv. supporting structures assist delivery and joining of gametes and, in females, the growth of the fetus during pregnancy 3. Gynecology is the medical specialty concerned with diagnosis and treatment of diseases of the female reproductive system; although urology is the study of the urinary system, urologists also diagnose and treat diseases and disorders of the male reproductive system. B. Male Reproductive System (p. 836) 1. The male reproductive system includes: i. testes (male gonads), which produce sperm and secrete hormones ii. system of ducts, which stores and transports sperm to the exterior iii. accessory sex glands, which produce secretions that mix with sperm to form semen iv. supporting structures including the scrotum and penis 2. Scrotum: (p. 836) i. the scrotum is an outpouching of the abdominal wall consisting of loose skin and superficial fascia that hangs from the root of the penis ii. externally, it has a median ridge called a raphe which separates the pouch into two lateral portions iii.
