An intact hymen is not a very good "proof" of virginity. Most girls will begin to menstruate
around the age of 10-15, but the average age of brides in the US is in the late twenties. If
the idea is that a woman is to have an intact hymen that is taught to break on the wedding
night as a sign of her virginity, then how is she menstruating as a youngster? There needs
to be a sufficient opening to the vagina once menstruation begins so that the menstrual
blood can leave the body. Pooling of blood inside of the vagina due to an intact hymen can
lead to a dilation of the vagina and uterus, which can cause retrograde bleeding leading to
endometriosis and peritonitis. - > True
,STDs like chlamydia or gonorrhea can cause something called pelvic inflammatory
disease (PID). PID is possible when the reproductive system opens into the abdominal
cavity. Which system, the biological male or the biological female opens into the
abdominal cavity? - > The biological female
Corpora cavernosa - > A pair of sponge-like tissue that contain most of the blood in the
penis during erection.
Epididymis - > A tube located at the back of each testicle that stores and carries sperm.
Seminiferous tubules - > Tightly coiled tubules in which sperm production takes place.
Corpus spongiosum - > Mass of spongy erectile tissue that surrounds the urethra in the
penis.
The vulva is the external genital organs of the female and consists of... - > Labia Minora
Mons Pubis
Labia Majora
Clitoris
What is the purpose of the scrotum? - > 1. To acts as a "climate control system" for the
testes.
2. In warm temperatures it lowers the testes away from the body.
3. In cold temperatures it pulls the testes closer to the body.
Sexual orientation - > An individual's physical and/or emotional attraction to the same
and/or opposite gender.
Gender role - > A set of social and behavioral norms that dictate how we should think,
speak, dress, and interact within the context of society.
Gender identity - > A person's individual internal sense and subjective experience of their
own gender.
Semen is made up of fluids from which of the following structures? - > Cowper's Gland
Seminal Vesicles
, Prostate Gland
What part of the penis has the most nerve endings? - > Glans
Where is the cervix found? - > Between the body of the uterus and the vagina.
Bulbocavernosus muscle - > Contracts to stop the flow of urine, and helps with erection
and the expulsion of semen.
Cremaster muscle - > Pulls the testes closer to the body during sexual arousal in
preparation for ejaculation.
Tunica dartos muscle - > Regulates the temperature of the testicles by either lowering or
pulling the scrotum to the body.
What hormone is largely responsible for breast development? - > Estrogen
Where is gonadotrophin-releasing hormone (GnRH) produced? - > Hypothalamus
Anabolic-androgenic steroids (AAS) are synthetically produced variants of the naturally
occurring hormone testosterone. Taking AAS will elevate testosterone levels yet
decrease sperm production, why is this? - > Because AAS negatively affects LH
What enzyme is needed to convert testosterone to estrogen? - > Aromatase
After ovulation, under the influence of LH, a new gland is formed from the follicle cells left
behind in the ovary. This gland is called the corpus luteum. The corpus luteum (yellow
body) secretes progesterone and estrogen, preparing the endometrium for a potential
pregnancy. - > True
When levels of testosterone in the biological male have fallen below the normal
physiological range, the "gonadostat" turns on the production of GnRH, which is being
released from the hypothalamus. This is called a negative feedback response since it
works on the same premise as a thermostat. - > True
What hormone triggers the expulsion of milk? - > Oxytocin
What is the inner lining of the uterus called? - > Endometrium
Breasts consists of: - > Fat Tissue
Loubles
Pectoralis Muscles
Milk Ducts
