Sexual Self Flashcards
- is considered “fundamental” sex because if a particular chemical prompting is absent, all fertilized eggs will develop into females.
Female sex
For a fertilized egg to become male, a cascade of chemical reaction must be present initiated by a single gene in the male chromosome called ______. Females do not have Y chromosome; hence, they do not have the this gene
SRY (sex-determining region of the Y chromosome)
- is the stage of development at which individuals become sexually mature. It can be separated intro five stages. the characteristics for each stage vary for girls and boys
Puberty
- popularized in the 1960’s and 1970’s
- describe areas of the body that are highly sensitive to stimuli and are often (but not always) sexually exciting)
erogenous zones
- these areas of the body have a high number of sensory receptors or nerve endings that. react to stimuli
highly sensitive
- serves as the primary erotic stimulus
The skin
two types of erogenous zones exist in the skin:
- Nonspecific type
- Specific type
a. its similar to any other portion of the usually haired skin.
b. the nerves supplying it are composed of the usal density of dermal-nerve networks and hair follicle networks.
c. the learned and anticipated pleasure sensations when a stimulus is presented in these regions produc the amplified sensation
d. the pleasurable sensation felt from theses regions is simply and exaggerated form of tickle.
e. examples: sides and bak of the neck, the axilla (armpit, underarm) and the sides of thorax (chest)
NONSPECIFIC TYPE
a. it is found in the mucocutaneous regions of the body or those regions made both of mucous membrane and of cutaneous skin
b. these regions favor acute perception
c. these specific sites of acute sensation are the genital regions, including the prepuce, penis, the female external genitalia (vulva), the perianial skin, lip, and nipple.
SPECIFIC TYPE
- is the retractable fold of skin covering the tip of penis
- nontechnical name: foreskin
- its also similar fold of skin covering the tip of clitoris
Prepuce
- is a male erectile organ of copulation by which urine and semen are discharged from the body
Penis
- a female sexual organ that is small, sensitive, and located in front of the opening of the vagina.
clitoris
- fleshy lips around the vagina. these are the outer folds of the vulva
labia majora
- inner lips, inner labia, vaginal lips or nymphae are two
flaps of skin on either side of human vaginal opening in the vulva situated between the labia majora.
labia minora
- opening that leads to vaginal canal
vaginal introitus
- is a membrane that surrounds or partially covers the external vaginal opening
hymen
- is a membrane that surrounds or partially covers the external vaginal opening
hymen
- area of the body surrounding the anus, in particular, the skin
- very sensitive
- its also susceptible to injury and damage
Perianal skin
-are soft, movable, and serve as the opening for food intake and in articulation of sound and speech
- are designed to be perceived by touch, and can be erogenous zone when used in kissing and any other acts of intimacy
Lips
- are raised region of tissue on the surface of the breast
- a recent study found that the sensation from it travels to the same part of the brain as sensations from the vagina, clitoris, and cervix
Nipples
- refers to the sequence of physical and emotional occurrences when the person is participating in a sexually stimulating activity, such as intercourse or masturbation
sexual response cycle
- pioneeres research to understand human sexual response, dysfunction, and disorders. They have been widely recognized for their contribution to sexual, psychological, and psychiatric research, particularly for their theory of a four-stage model of sexual response ( also known as the human sexual response cycle)
William Masters and
Virginia Johnson
4 phases of human sexual response
Excitement
Plateau
Orgasm
Resolution
Muscle tension increases.
Heart rate quickens, and breathing is accelerated
Skin may become flushed (blotches of redness appear on the chest and back)
Nipples become hardened or erect.
Blood flow to the genitals increases, resulting in swelling of the woman’s clitoris and labia minora (inner lips), and erection of the man’s penis.
Vaginal lubrication begins.
The woman’s breasts become fuller and the vaginal walls begin to swell.
The man’s testicles swell, his scrotum tightens, and he begins secreting a lubricating liquid.
Phase 1: excitement
