CHAPTER 1 Flashcards
Biological differences between males and females.
Sex
What are the two categories of biological differences?
- Primary sex characteristics (genital differences)
- Secondary sex characteristics (hormonal differences)
includes internal and external genitals.
Primary sex characteristics
Genital differences:
MEN =
WOMEN =
MEN = penis and testes
WOMEN = clitoris and ovaries
- Includes non-genital differences
Secondary sex characteristics
Hormonal differences:
MEN =
WOMEN =
MEN = testosterone
WOMEN = estrogen
T or F
Men are usually taller and physically stronger than women, have more facial hair and they more often tend to go bald.
T
- study of the structures of the human body, such as the features of how the organs, tissues and body systems are constructed.
ANATOMY
- study of the coordinated functions of the organs, tissues and systems in the body.
PHYSIOLOGY
Allow women to become pregnant and bear children. While the reproductive organs in the female anatomy perform their own specific functions, they also work together as a highly complex, interrelated system
Female reproductive organ
“reproduction in humans”
GAMETE PRODUCTION
In human meiosis, diploid cells with the usual 46 chromosomes divide into four haploid daughter cells, each containing 23 chromosomes.
Each of these daughter cells is called a gamete.
MEIOSIS
What type of cell is responsible in meiosis? how many pair of chromosomes?
Diploid cells, 23 pair of chromosomes (46 all)
Each of these daughter cells is called
Gamete
In Females this meiotic process is called? and the daughter cells are called?
OOGENESIS, OVA
Males begin ______ at puberty and continue throughout life
spermatogenesis
T or F
Healthy young adult males produce hundreds of millions of sperm each day. This number begins to decline by their mid-20s.
T
(Male or Female) begin to produce gametes before they even are born.
Females
By the _____ month in womb, female fetuses have begun oogenesis, but the process pauses after a phase called ______ suspending the ova in the primary oocyte stage until puberty. 99.9 % of a female’s ova remain in the primary oocyte stage until they are eventually absorbed by the body.
fifth, prophase I
T or F
Millions are absorbed by the time a fetus is born, and by puberty, only 400,000 remain. For every ovulation, about 2,000 more ova are absorbed.
T
“four stages of the human sexual response cycle”. It occurs during partnered sex with people of any gender, as well as other sexual stimulation activities
SEXUAL INTERCOURSE
What are the 4 stages of sexual intercourse?
- Excitement
- Plateau stage
- Orgasm
- Resolution
It is the beginning of arousal, in which blood flow increases and causes engorgement in the genitals and nipples, accompanied by an increase in heart rate, breathing rate, muscle tone and blood pressure
The first stage is EXCITEMENT
