Cards

Term
sex
(genetic vs anatomical)
Definition
biological malesness/femaleness
genetic: determined by chromosomes
anatomical: external characteristics
Term
gender
Definition
psychosocial meaning of male/female
Term
gender identity
Definition
subjective sense of being male or female
Term
gender (sex) role
Definition
cultural norms for male/female behavior
Term
gender assumptions
Definition
assumptions about how people are likely to behave based on their male/femaleness; gender identification
Term
gender (biologically)
Definition
the biological sex is determined by the chromosomal makeup of the sperm that fertilizes the ovum; reproductive cells have 22 matched chromosomes (autosomes); the 23rd pair of chromosomes determines the sex; xx-female; xy-male
Term
gonads
Definition
SRY gene triggers testes; DSS gene triggers ovaries; gonads differentiation forms around 6th week
Term
wolffian ducts vs mullerian ducts
Definition
androgens (testosterone) stimulate production of vas deferens, seminal vesicles, and ejaculatory ducts
vs
there is no androgen stimulation (in females), so fallopian tubes, uterus, and inner third of vagina form
Term
ovaries produce:
1. estrogens
2. progestational compounds
Definition
1. influence dev of 2ndary sex characteristics; regulate menstrual cycle; estradiol most imp
2. progesterone is only one of physiological importance; regulates menstrual cycle; stimulates dev of uterine lining in preparation for pregnancy
Term
testes produce:
androgens
Definition
testosterone most important; influence dev of male 2ndary sex characteristics
***Adrenal glands in both sexes secrete small amounts of estrogen and larger amounts of androgen***
Term
3 major brain structures vary b/w males and females
Definition
1. hypothalamus
2. left and right cerebral hemispheres
3. corpus callosum
Term
true hermaphrodite
Definition
have both ovarian and testicular tissue in body- VERY RARE
Term
pseudohermaphrodite
Definition
external genitals are a mixture of male and female structures; gonads match chromosomal sex; caused from atypical combination of sex chromosomes or prenatal hormone irregularities
Term
intersexed
Definition
people who possess biological attributes of both sexes
Term
Turner's Syndrome

Term
Androgen Insensitivity Syndrome (AIS)
Definition
chromosomally normal males insensitive to testosterone; develop female external genitals, so usually not discovered until absence of period at older age; female gender i.d.
Term
Fetally Androgenized Females
Definition
chromosomally normal females prenatally exposed to excessive androgens; enlarged clitoris resembles penis and fused labia resembles scrotum; i.d. as female and treated w/ surgery/hormone therapy; high discomfort w/ female sex assignment
Term
DHT- deficient males
Definition
normal XY male develops externals of female bc of defect that prevents conversion of testosterone into DHT; so i.d.'d at birth as female; at puberty there's accelerated testosterone pro. that reverses DHT deficency and externals enlarge into male genitals; rapid transformation- most make gender i.d. switch from female to male
Term

one's relationship w/ father and mother are crucial in psychosocial development; all children pass through "homoerotic phase"- boys become fixated in this phase if poor relationship w/ father & overly close reL w mother-- same for women if they dev penis envy; (same sex exploration when young is normal/part of dev); but freud's been disproved and no particular family dynamic is specific to homo/hetero dev
Term
twin studies
compare fraternal vs identical twins
Definition
identical twins have identical genetic material; if a trait has more likeness bw identicals than w/ fraternals, then it's linked to biological influences; so the higher likeness rates for identical vs fraternal indicates a biological/genetic influence (but direct cause still under speculation)
Term
gay- affirmative therapy
