ANATOMY & PHYSIOLOGY TERMINOLOGY-MALE AND FEMALE REPRODUCTIVE SYSTEMS



ANATOMY & PHYSIOLOGY TERMINOLOGY-MALE REPRODUCTIVE SYSTEMS
Male reproductive system

Reproductive / Genital System: A group of organs that work together for the purpose of reproduction.

Reproduction: A biological process by which individual organisms are produced. Though male and female reproductive systems are separate & unique, they both work together for the purpose of reproduction.

Functions of Reproductive System: The main function of the reproductive system is to ensure the survival of the species.

1. To produce gametes (eggs in female and sperm cells in a male)

2. To transport and nourish gametes

3. To nurture the developing offspring (embryo/fetus) in females.

4. To produce hormones that regulate the physiology of the reproductive system.

Internal genitalia: Genital organs that are located inside the body.

External genitalia: Genital organs that are located outside the body.

Functions of the Male Reproductive System:

1. To produce, nourish, and transport spermatozoon/sperm and semen.
2. To discharge the sperm within the female reproductive tract
3. To produce male sex hormones

External Male Genitalia: Penis, scrotum, testes, and epididymis.

Internal Male Genitalia: Vas deferens, ejaculatory duct, seminal vesicles, prostate gland, and bulbourethral glands.

Male Primary Reproductive Organs: Testes / Testicles.

Male Secondary Reproductive Organs: Ducts, glands, and penis.

Penis: A male organ for sexual intercourse, which conveys semen and urine. Three parts of the penis are the root, body/shaft, and glans/head. When a man reaches orgasm (sexual climax), semen, which contains sperm, is ejaculated through the end of the penis.

Glans penis: Cone-shaped end portion of the penis, covered with foreskin/prepuce.

Scrotum: Scrotum is a loose pouch-like sac of skin that hangs behind the penis. The scrotum contains testes and many nerves and blood vessels. The median septum divides the scrotum into 2 chambers. Each chamber houses a testis and an epididymis. Scrotum serves as a temperature regulator for testes. For normal sperm development, testes must be at a temperature slightly cooler than the body temp.

Muscles of Scrotum: Dartos Muscle and Cremaster Muscle

Testes / Testicles: Testes are paired oval organs that lie in the scrotum. Testes produce gametes (spermatozoon/sperm) and the primary male sex hormone (testosterone). Seminiferous tubules in testes are responsible for spermatogenesis.

Epididymis: A long coiled tube located at the backside of each testicle. Transports and stores sperm cells that are produced by the testes. Epididymis brings the sperm (immature) to maturity.

Vas deferens: Helps to transport the developed sperm to the urethra in preparation for ejaculation

Ejaculatory ducts: The ejaculatory ducts are formed by the fusion of vas deferens and seminal vesicles. The ejaculatory ducts enter into the urethra.

Urethra: Urethra is a tube that carries urine from the bladder to the outside of the body. The urethra also expels semen when a man reaches orgasm.

Seminal vesicles: Seminal vesicles are sac-like pouches that are attached to the vas deferens near the base of the bladder. Seminal vesicles produce sugar-rich fluid (fructose) that provides energy to the sperm that helps in sperm's motility.

Prostate gland: Located below the urinary bladder, in front of the rectum. The prostate gland releases prostate fluid to help nourish the sperm.

Bulbourethral / Cowper's glands: Located on the sides of the urethra just below the prostate gland. Bulbourethral glands produce a clear, slippery fluid to lubricate the urethra and to neutralize any acidity.

Gamete: Sex or Reproductive cell. Sperm in males and Ovum in females.

Gonads:
The reproductive organs that produce gametes.

Sperm: Sperm that emerge from testes is immature and incapable of fertilization.

Flagellum: Hair-like process in a sperm cell for motility purposes.

Ejaculation: Expulsion of sperm with fluid from the male urethra.

Testosterone: A primary male sex hormone secreted by the testes, which is responsible for male sex characteristics.

Semen:  (prostatic and other glandular secretions)
Spermatozoa and fluid.

Erectile Dysfunction: Inability to attain or maintain an erection sufficient for penile penetration (sexual intercourse)

Phimosis: Narrowing of the opening of the foreskin/prepuce

Coitus: Sexual intercourse

Puberty: When secondary sex characteristics develop

Cryptorchism / Cryptorchidism: Undescended testicles

Epispadias / Epispadias: Congenital opening of the male urethra on the upper surface of the penis

Hypospadias/Hypospadias: Congenital disorder. Where male urethra opens undersurface of the penis

Semen Analysis: A test done to determine fertility and effectiveness of vasectomy

ANATOMY & PHYSIOLOGY TERMINOLOGY-FEMALE REPRODUCTIVE SYSTEMS
Female Reproduction


Functional Division of Female Reproductive System:

1. Primary reproductive organs - Ovaries
2. Secondary reproductive organs - Fallopian tubes, uterus, vagina, vulva.

Functions of the Female Reproductive System:

1. Produce and nourish female gametes (ovum/egg).
2. Transport gametes to a site where they may be fertilized by the sperm.
3. Provide a favorable environment for the developing fetus.
4. Deliver the fetus to the outside world once the development is completed.
5. Produce female sex hormones - estrogen and progesterone

Ovaries: Small oval / almond-shaped glands that are located on either side of the uterus. Ovaries are female gonads. They produce female gametes (ovum/egg) and hormones (estrogen and progesterone)

Fallopian tubes / Uterine tubes: Narrow muscular tubes that are attached to the upper part of the uterus. They transport ova from ovaries to the uterus. Conception/fertilization occurs in fallopian tubes. The fertilized ovum then moves to the uterus from fallopian tubes.

Parts of the fallopian tube: isthmus, ampulla (body), infundibulum, fimbriae, mesosalpinx.

Uterus/womb: A thick-walled, pear-shaped muscular chamber that acts as a home for a developing a fetus. The uterus is located in the pelvis anterior to the rectum and posterior to the urinary bladder.

Parts of uterus: fundus, corpus, isthmus, cervix.

Layers of the uterus: Uterine wall is made up of 3 layers. 1. Perimetrium. 2. Myometrium. 3. Endometrium

Uterine ligaments: 
1. Broad ligaments (mesometrium). 
2. Uterosacral ligament. 
3. Round ligaments. 
4. Cardinal (lateral cervical) ligaments

Hymen: A mucous membrane that partially covers the entrance of the vagina.

External female genitalia called as: Vulva / pudendum.

Clitoris:  sensitive erectile organ or tissue positioned anterior to the vaginal orifice and in front of the urethral meatus. The clitoris creates sensations of pleasure during sexual intercourse.

Vestibule: The space between the labia minora that contains the vaginal and urethral openings.

Vestibular glands and types: Glands located around the vestibule and open into it. They secrete a fluid, which moistens and lubricates the vestibule. Types of vestibular glands: 1. Greater vestibular glands or Bartholin's glands. 2. Lesser vestibular glands or Skene's glands or paraurethral glands.

Puberty: A natural phenomena in which the body moves into the adult phase, and capable of sexual reproduction. Puberty in females begins in early teens, generally between 11-14 years of age. At puberty, female gametes are released by gonads, sex hormones are secreted by gonads, and secondary sex characteristics are developed.

Puberty Vs Adolescence: Puberty: Limited to physical changes of sexual maturation. Adolescence: Psychological and social transition between childhood to adulthood.

Gonadotropins in women: FSH and LH.

Estrogen: It is a hormone produced by ovaries. Estrogen stimulates the development of secondary sex characteristics and prepares the uterus for pregnancy (endometrium gets thickened).

LH: A hormone produced by the pituitary gland. LH stimulates ovulation and luteinization.

Menarche: First menstrual period i.e., the onset of the menstrual cycle.

Pubarche: First appearance of pubic hair in a child.

Thelarche: Onset of breast development.

Menstrual cycle: Regular monthly reproductive cycle of a woman, the cycle lasts 28 days.

Phases of the menstrual cycle:

1. Menstrual phase - Days 1-5 - Period in which menstruation occurs (shedding of the uterine lining).
2. Proliferative phase - Days 6-13 - Period of endometrial repair.
3. Secretory phase - Days 14-28 - Period during which empty follicle develops into corpus luteum that secrets progesterone and estrogen.
