Chapter 11 Flashcards
A source of pleasure, excitement, and connection with other people, and is even good for your health.
Sexual activity
Satisfying intimate relationships based on mutual respect and trust and the ability and resources to procreate if so desired. It involves acceptance of our own sexual feelings and tolerance for those of others. It also includes knowledge about sexuality and access to the information needed to make responsible decisions.
Sexual health
Positively valued feelings induced by sexual stimuli.
Sexual pleasure
True or False?
Sensory signals arriving in the brain are not inherently pleasurable; rather, the brain interprets them as pleasurable. This interpretation and evaluation of stimuli by the brain as sexually pleasurable is influenced by everything the individual has learned about sex in his or her society and culture, including expectations, attitudes, and values.
True
the biological purpose of sexuality
reproduction
Responsible for the production of ova and, if pregnancy occurs, the development of the fetus.
female sex organs
Responsible for producing sperm and delivering them into the female reproductive system to fertilize the ovum.
male sex organs
Organs of a female that include vagina, cervix, uterus, fallopian tubes, and ovaries.
internal sex organs
muscular tube extending from the external vaginal opening to the cervix.
Vagina
lower part of the uterus; extends into the vagina and contains openings to the uterus. Produces mucus that changes with different stages of the menstrual cycle.
cervix
Size of a pear. Organ in which a fertilized egg develops into an embryo and then a fetus.
uterus
layer of uterus that is shed during menstruation.
endometrium
Female reproductive glands that store and release the ova (eggs) every month, usually one at a time—the process of ovulation. They also produce the female sex hormones estrogen and progesterone. Are located on either side of the uterus.
ovaries
Mammary glands. They consist of 15 to 25 lobes that are padded by connective tissue and fat. Within the lobes are glands that produce milk when the woman is lactating following the birth of a baby. At the center of each is a nipple, surrounded by a ring of darker-colored skin called the areola. The nipple becomes erect when stimulated by cold, touch, or sexual stimuli.
breasts
Include the penis and the scrotum which contain the testes.
external genitalia
When erect, is designed to deliver sperm into the female reproductive tract. The shaft of this is formed of three columns of spongelike erectile tissue that fill with blood during sexual excitement. The glans, or head of this, is an expansion of the corpus spongiosum (one of the three columns of erectile tissue in the shaft). The glans contains a higher concentration of nerve endings than the shaft and is highly sensitive.
penis
Crownlike structure that protrudes slightly and forms a border between the glans and the shaft; it is also highly sensitive.
corona
Fold of skin extending from the corona to the foreskin. The foreskin, or prepuce, covers the glans, more or less completely.
frenulum
Removes this skin and leaves the head of the penis permanently exposed.
circumcision
contains testes, separated from the body.
scrotum
Summer heat is capable of causing the penis to expand as blood vessels dilate to allow temperature regulation. There is actually no increase in size of the penis, but the skin appears thicker. Although, in the winter, the penis will contract as the body conserves internal heat.
“summer penis”
True of False?
Health scientists believe the penis’s reaction to ambient temperature is associated with the need to maintain a specific temperature in the testes to produce sperm. The scrotum skin expands in warm ambient temperatures and contracts in cold temperatures.8 Still, the reality is that there is no enlargement of the man’s penis in summer heat.
True
Our country was rooted in this belief that sex was only for procreation and that sex for any other purpose was sinful.
Puritan belief
The presence of this causes the reproductive glands to develop into testes. The testes produce testosterone which causes the undifferentiated reproductive structures to become male sex organs. If there is no presence of this, the glands develop into ovaries, and the reproductive structures become female sex organs.
Y chromosome
Between what ages does menstruation occur?
12-50
When women experience cramps, backache, headache, irritability, and mood swings
premenstrual syndrome (PMS)
