The document summarizes the male and female reproductive systems. The female system includes internal organs like the ovaries, fallopian tubes, uterus, and vagina. The ovaries produce eggs and hormones, while the fallopian tubes and uterus support fertilization and pregnancy. Externally, the system includes the vulva, clitoris, and breasts. The male system includes internal organs like the testes, epididymis, vas deferens, seminal vesicles and prostate that work together to produce, mature and store sperm for reproduction. Externally it includes the penis and scrotum.
The female reproductive system is made up of internal organs and external structures. Its function is to enable reproduction of the species. Sexual maturation is the process that this system undergoes in order to carry out its role in the process of pregnancy and birth.
The reproductive organ in female are those which concerned with copulation, fertilization, growth and development of fetus and its subsequent exit to the outer world.
Roles of Female Reproductive System
Produce sex hormones
Estrogen, Progesterone
Produce egg (ova or oocytes)
Support & protect developing embryo
Give birth to new baby
The female reproductive organs can be subdivided into:
External genitalia or Vulva
Internal genitalia
Accessory reproductive organs.
The vulva refers to those parts that are outwardly visible.
The vulva includes:
Mons pubis
Labia majora
Labia minora
Clitoris
Urethral opening
Vaginal opening
Perineum
MONS PUBIS
The triangular mound of fatty tissue that covers the pubic bone
It protects the pubic symphysis
During adolescence sex hormones trigger the growth of pubic hair on the mons pubis
Hair varies in coarseness curliness, amount, color and thickness
LABIA MAJORA
Referred to as the outer lips
They have a darker pigmentation
The Labia Majora:
Protect the introitus and urethral openings
Are covered with hair and sebaceous glands
Tend to be smooth, moist, and hairless
The labia majora contain sweat and oil-secreting glands
Become flaccid with age and after childbirth
LABIA MINORA
Referred to as the “inner lips”
Made up of erectile, connective tissue that darkens and swells during sexual arousal
Located inside the labia majora
They are more sensitive and responsive to touch than the labia majora
The labia minora tightens during intercourse
CLITORISHighly sensitive organ composed of nerves, blood vessels, and erectile tissue
It is made up of a shaft and a glans
Becomes engorged with blood during sexual stimulation
Key to sexual pleasure for most women
Urethral opening is located directly below clitoris
VAGINAL OPENING INTROITUSOpening may be covered by a thin sheath called the hymen
Using the presence of an intact hymen for determining virginity is erroneous
The hymen can be perforated by many different events

a brief presentation of both the males and females reproductive system, anatomy and its physiology, outlined in sequentially and in a way easier to understand.
This presentation includes data from 2009 and 2010 on teens and adults sending or receiving sexually suggestive nude or nearly nude images by cell phone - also called sexting. Presented to the 2010 conference of the Association of Internet Researchers, the talk includes demographic data on who engages in these behaviors, as well as some teen focus group data on the differences in language used to talk about sexting experiences between boys and girls.

MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
