SRY Gene: Found on the Y chromosome, it triggers male development. Without SRY: The embryo develops as female. Gonadal Cells: Both sexes start with the same cells that can become testes or ovaries.  Practice Question Where are the testes located for most of the gestational time?  Practice Question Where are the testes located for most of the gestational time?

Sensations are amplified Zones through learned pleasurable responses. The sensation is akin to an exaggerated tickle. Erogenous Zones - Sensitive areas of the body linked to pleasure, with high SPECIFIC ZONES sensory receptors. Sensitivity varies per individual. Located in mucocutaneous Brain interpretation plays a role in regions (mucous membrane + sexual response. skin). Both pleasure and pain can be felt in Associated with acute perception. these areas.  NONSPECIFIC SPECIFIC Nonspecific Type: Sensitivity amplified Acute sensitivity in mucocutaneous through learned responses (e.g., neck, areas (e.g., genital regions, lips, nipples, armpits, sides of the thorax (chest). perianal skin). The sensation is akin to an Associated with acute perception. exaggerated tickle.  ANATOMICAL DETAILS PREPUCE (foreskin); Fold of skin covering the tip of the penis and clitoris PENIS Male organ for copulation and discharge of urine and semen (female external genitalia); Mons pubis, clitoris, labia majora and VULVA minora, vaginal introitus, hymen PERIANAL SKIN Sensitive area surrounding the anus, prone to injury. LIPS Soft and movable; sensitive during kissing and intimacy. Tissue on breasts; sensations travel to the same brain areas as NIPPLES genital sensations.  Understanding the Human Sexual Response In the late 1950s, researchers William Masters and Virginia Johnson pioneered the study of human sexual response, dysfunction, and disorders, significantly contributing to sexual, psychological, and psychiatric research, including the development of the four-stage model of the sexual response cycle.  Chaeracteristics General Phase 1: Phase 2: Phase 3: Phase 4: Excitement Plateau Orgasm Resolution Increased muscle Intensified arousal Involuntary muscle Return to normal body tension Clitoral contractions state Accelerated heart rate sensitivity/retraction Peak heart rate, Sense of well-being and breathing Testicles retract breathing Fatigue Skin flushing Muscle spasms Release of sexual Refractory period Genital swelling (clitoris, Increased tension (men) penis) cardiovascular Female vaginal/uterine Multiple orgasms Vaginal lubrication response (heart rate, contractions possible (women) (women) breathing, blood Male ejaculation Testicular swelling pressure) (men) SEX and t h e Brain The xual Behavior e Ba S sic of log y Bio  ROLES OF BRAIN ROLES OF HORMONES Pleasurable Sensations: Translates nerve Hypothalamus: Controls sexual function, linked to impulses from the skin into pleasure. the Pituitary Gland for hormone secretion. Nerve & Muscle Control: Manages the physical Oxytocin: "Love hormone," released during orgasm, actions during sexual activities. promotes closeness. Sexual Thoughts & Fantasies: Controlled by the FSH: (Follicle-Stimulating Hormone) Triggers Cerebral Cortex, linked to reasoning. ovulation; sexual activity peaks during fertility. Emotions & Feelings: Originate in the Limbic LH: (Luteinizing Hormone) Regulates testosterone in System, crucial for sexual behavior. men, a key driver of male sexual motivation. Hormonal Release: Driven by the brain, hormones Vasopressin: Boosts male arousal and sexual trigger sexual desire. motivation. Estrogen & Progesterone: Regulate female sexual desire; estrogen increases, progesterone decreases.  Chemistry of t r a c t o n m ent Lust A t i Att a c h LUST Erotic Passion Marked by physical attraction and the desire for seduction. Driven by testosterone in men and estrogen in women. Lust alone does not guarantee lasting love.  ATTRACTION Characterized by a craving for your partner's Romantic Passion presence, excitement, and Dopamine: Drives fantasizing about shared motivation and excitement, experiences. making partners feel special. Triggered by three key Serotonin: Low levels lead chemicals: to obsessive thoughts, like Norepinephrine: those in love. Increases energy and alertness; reduces appetite and sleep. ATTACHMENT Commitment Represents the desire for a lasting bond, including aspirations for marriage and family. This stage solidifies the emotional connection and commitment between partners.  SUMMARY Sex and the Brain: Controls sexual responses, emotions, and releases hormones. SRY Gene: Triggers male development; without it, the body defaults to female. Primary & Secondary Characteristics: Primary (reproductive organs), Secondary (develop during puberty). Erogenous Zones: Sensitive areas like lips, nipples, and genitals. Puberty: Rapid changes, development of reproductive and secondary traits. Sexual Response Phases: Excitement, Plateau, Orgasm, Resolution. Love Chemistry: Lust, Attraction, and Attachment driven by hormones and neurotransmitters.  An y f in a l qu es ti o n s o r clari fi ca tio n s ?  Q U IZ T IM E!
