Finals: Sexual Behavior Flashcards
• An individual’s genetic sex begins with sex chromosomes inherited from two parents.
• Mothers provide an X chromosome to all their offspring;
• Fathers determine the offspring’s sex by providing either another X ( producing a female) or a Y chromosome (producing a male).
Sexual development
- The internal organs, ovaries in females and testes in males, that produce reproductive cells (eggs and sperm) and secrete sex hormones.
Gonads
- The external sexual organs, including the penis and scrotum in males and the labia, clitoris, and lower third of the vagina in females.
External genitalia
- A condition in which elements of both male and female development occur in the same fetus.
Intersex
- Male gonads; source of sperm and sex hormones.
Testes
The internal system that develops into seminal vesicles, vas deferens, and the prostate gland in males.
Wolffian system
- The internal system that develops into a uterus, fallopian tubes, and the upper two thirds of the vagina in the absence of anti-Müllerian hormone.
Müllerian system
- An androgen produced primarily in the testes.
Testosterone
- A hormone secreted by fetal testes that causes the degeneration of the Müllerian system.
Anti-Müllerian hormone
- A steroid hormone that develops and maintains typically masculine characteristics.
Androgen
- Female gonads; the source of ova and sex hormones.
Ovaries
- A gene located on the short arm of the Y chromosome that encodes for testis-determining factor.
sex-determining region of the Y chromosome (SRY)
- include facial hair and a deeper voice for males and wider hips and breast development for females.
Secondary sex characteristics
The average age of puberty has dropped dramatically over the past century and a half, from about_____ to about _____ years of age.
16 to about 12 yrs of age
A hormone released by the hypothalamus that stimulates the release of lutenizing hormone (LH) and follicle-stimulating hormone (FSH) by the anterior pituitary gland.
Gonadotropin-releasing hormone (GnRH)
- A hormone released by the anterior pituitary that stimulates the development of eggs in the ovaries and sperm in the testes.
Follicle-stimulating hormone (FSH)
A hormone released by the anterior pituitary that signals the male testes to produce testosterone and that regulates the menstrual cycle in females.
Luteinizing hormone -
also affects a male’s hairline and can result in baldness later in adulthood.
Testosterone
In females, ____ produces breast growth, maturity of the external genitalia, maturity of the uterus, and changes in fat distribution and quantity.
estradiol
are classified as steroids, chemicals that are synthesized from cholesterol in the gonads and in lesser amounts, in the adrenal glands.
Sex hormones
One of several clusters of cells in the ovary each of which contains an egg cell.
Follicle
- A female reproductive cell, or egg.
Ovum
- The process of releasing a mature egg from the ovary.
Ovulation
- A hormone produced in the corpus luteum that prevents the development of additional follicles and promotes the growth of the uterine lining.
Progesterone
- A condition in which some women experience physical and psychological symptoms immediately prior to the onset of menstruation.
Premenstrual syndrome
- A condition in which premenstrual mood changes are unusually severe.
Premenstural dysphoric disorder (PMDD)
- A condition in which mothers who have recently given birth experience feelings of depression due to their rapidly changing hormonal environment.
Postpartum depression
who made the the triangular theory of love?
Robert Sternberg
- encompasses teelings of attachment, closeness, connectedness, and bondedness.
Intimacy
- encompasses drives connected to both limerance and sexual attraction.
Passion
- encompasses, in the short term, the decision to remain with another, and in the long term, the shared achievements and plans made with that other person.
Commitment
• Intimate human relationships start in acquaintanceship. Crucial stage is attraction. Attraction can take place in an enabling environment.
Acquaintance
- closeness
Proximity
- repeated interaction
Exposure
- common preferences
Similarity
• The stage when two persons test their boundaries. They test the waters before engaging fully and so committedly in the relationship.
Buildup
• The stage is when people commits to a long-term relationship with one another, either through a personal agreement.
• Ex. What makes a people commit to a relationship, maybe to the point of marriage?
Consolidation and Continuation
• The stage is when people commits to a long-term relationship with one another, either through a personal agreement.
• Ex. What makes a people commit to a relationship, maybe to the point of marriage?
Consolidation and Continuation
for those intimate partnerships who are unable to address the causes and circumstances leading deterioration
to the of their relationship, the stages culminate into ending or termination of the agreements made.
Ending
• Unfortunately, some intimate partnerships are unable to sustain and maintain their commitments or attraction.
Decline or Deterioration
