Reproductive

Question: what makes fertilization likely? 1 less likely ; rhe rest are likley

-acidity of the vag -mucus plug blocks sperm -WBC attack and destroy sperm/ phagocytosis -length of female reproductive tract -enzymes prematurley prevent sperm from breaking through -not enough sperm

Bartholin's glands

Glands located on either side of the vaginal opening that secrete mucus for vaginal lubrication.

What is the same in male and females in reproductive?

In both males and females, the sex gland called the gonads evolves to form ovaries and testes in females and males, respectively. Since ovaries and testes are derived from the same organ, gonads are called homologus organs.

Question: Glands in the female reproductive

In female human anatomy, Skene's glands or the Skene glands (/skiːn/ SKEEN; also known as the lesser vestibular glands, paraurethral glands, or homologous female prostate) are glands located on the anterior wall of the vagina, around the lower end of the urethra.

Third stage for women

Involuntary muscle contractions begin. Blood pressure, heart rate and breathing are at their highest rates, with a rapid intake of oxygen. Muscles in the feet spasm. There is a sudden, forceful release of sexual tension. In women, the muscles of the vagina contract. The uterus also undergoes rhythmic contractions. In men, rhythmic contractions of the muscles at the base of the penis result in the ejaculation of semen. A rash or "sex flush" may appear over the entire body

Stage 1 for women:

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.

Question: female reproductive trace -what is not apart of the trace?

Ovarian follicle---Infundibulum---Ampulla of oviduct-----Oviduct----Isthmus of oviduct---Fundus of uterus----Body of uterus----Internal os----Cervical canal---External os----Vagina---vaginal orifice-------Vestibule

Question: Ovulation occurs this day we might expect implantation ovulation on this day? Reworded: When might we expect to be the first day when secondary ooycte is in the infundidum

Ovulation happens about 14 days before your period starts. If your average menstrual cycle is 28 days, you ovulate around day 14, and your most fertile days are days 12, 13 and 14. If your average menstrual cycle is 35 days ovulation happens around day 21 and your most fertile days are days 19,20 and 21.

Sertoli cells

Sertoli cells are the somatic cells of the testis that are essential for testis formation and spermatogenesis. Sertoli cells facilitate the progression of germ cells to spermatozoa via direct contact and by controlling the environment milieu within the seminiferous tubules.

cells of leydig (interstitial cells)

Specialized cells in spaces between seminiferous tubules, that secrete male sex hormones (Testosterone)

Question: what is the secretion in regulation with spermatogenesis

Testosterone is the major androgen in the testis that regulates spermatogenesis. Testosterone is produced by the Leydig cell in response to stimulation with luteinizing hormone (LH) and acts as a paracrine factor that diffuses into the seminiferous tubules.

ovarian cycle

The 28 days of the menstrual cycle as they apply to events in the ovary. The ovarian cycle has three subphases: the follicular phase, ovulation, and the luteal phase.

Sertoli cells secrete

The Leydig cells make and secrete testosterone, in response to lutenising hormone from the pituitary. The cholesterol is used in the first step of testosterone production. ... FSH stimulates the Sertoli cells to secrete androgen-binding protein into the lumen of the seminiferous tubules.

Stage 2 for women:

The changes begun in phase 1 are intensified. The vagina continues to swell from increased blood flow, and the vaginal walls turn a dark purple. The woman's clitoris becomes highly sensitive (may even be painful to touch) and retracts under the clitoral hood to avoid direct stimulation from the penis. The man's testicles are withdrawn up into the scrotum. Breathing, heart rate and blood pressure continue to increase. Muscle spasms may begin in the feet, face and hands. Tension in the muscles increases.

phases of menstrual cycle

The four phases of the menstrual cycle are menstruation, the follicular phase, ovulation and the luteal phase.

Question: what is homologous in both males and females?

The human reproductive system has many glands (the male's more than the female's), but the bulbouretThe various reproductive organs work together to: produce gametes (egg and sperm cells); transport and sustain these cells; nurture and maintain the developing zygote/fetus (female only); produce sex hormones (male = testosterone, female = estrogens and progesterone).hral glands in males are homologous to the Bartholin's glands in females. They are both considered accessory glands. -The various reproductive organs work together to: produce gametes (egg and sperm cells); transport and sustain these cells; nurture and maintain the developing zygote/fetus (female only); produce sex hormones (male = testosterone, female = estrogens and progesterone). Structures such as testes and ovaries that arise from the same undifferentiated embryonic tissues in males and females are called homologous structures

female external genitalia

The mons pubis is a rounded mound of fatty tissue that covers the pubic bone. During puberty, it becomes covered with hair. The mons pubis contains oil-secreting (sebaceous) glands that release substances that are involved in sexual attraction (pheromones). The labia majora (literally, large lips) are relatively large, fleshy folds of tissue that enclose and protect the other external genital organs. They are comparable to the scrotum in males. The labia majora contain sweat and sebaceous glands, which produce lubricating secretions. During puberty, hair appears on the labia majora. The labia minora (literally, small lips) can be very small or up to 2 inches wide. The labia minora lie just inside the labia majora and surround the openings to the vagina and urethra. A rich supply of blood vessels gives the labia minora a pink color. During sexual stimulation, these blood vessels become engorged with blood, causing the labia minora to swell and become more sensitive to stimulation.

ovulation phase

The second stage of the general menstrual cycle, when the ovum is released.

Question: stages of the different female sexual acts?

The sexual response cycle has four phases: desire (libido), arousal (excitement), orgasm and resolution. Both men and women experience these phases, although the timing usually is different. ... Several physiologic changes may occur during different stages of sexual activity.

luteal phase

The third phase of the ovarian cycle, during which a corpus luteum is formed from the remnants of the follicle that has ovulated its oocyte. The corpus luteum secretes progestrone and estrogen during this time period, which typically lasts from day 15 to day 28 of the menstrual cycle. Formation of the corpul luteum is triggered by the same LH surge that triggers ovulation, however in the absence of LH (levels quickly decline after the surge) the corpus luteum begins to degenerate.

secretory phase

The third phase of the uterin (endometrial) cycle, during which the rebuilt endometrium is enhanced with glycogen and lipid stores. The secretory phase is primarily under the controll of progestone and estrogen (secreted from the copus luteum during this time period), adn typically lasts from day 15 to day 28 of the menstrual cycle.

Question: Glands in the reproductive system (male)

Three accessory glands provide fluids that lubricate the duct system and nourish the sperm cells. They are the seminal vesicles, the prostate gland, and the bulbourethral glands (Cowper glands).

prostate

bladder to the penis, letting urine flow out of the body. The prostate secretes fluid that nourishes and protects sperm.

internal genitalia male

include the vas deferens, seminal vesicles, ejaculatory ducts, prostate gland, and bulbourethral glands

bulbourethral glands (Cowper's glands)

located on either side of urethra in males; adds alkaline substance to semen

menstration phase

menstrual cycle during which the lining of the uterus is shed (the first day of menstrual flow is considered day 1 of the menstrual cycle) Type of: phase, stage. any distinct time period in a sequence of events.

proliferaive phase

occurs as a response to increasing levels of estrogen: during the follicle stage

internal genitalia of female

ovaries, uterine tubes, uterus, vagina

secondary oocyte move into the infundibulum following ovulation?

same thing as saying ovulation

male external genitalia

scrotum and penis

follicle

the sac in the ovary in which the egg develops

seminal vesicles

two small glands that secrete a fluid rich in sugar that nourishes and helps sperm move
