Anatomy and Physiology = Bio 2020; CH 28
| Term | Definition |
|---|---|
| Ovaries and testes produce gametes. | True |
| Labia majora and scrotum | Covering and protection |
| Vestibular and bulbourethral glands | Secrete lubricant |
| Clitoris and glans of penis | Stimulate sexual arousal |
| Both female and male reproductive systems are primarily nonfunctional until puberty | True |
| Puberty is initiated when the hypothalamus significantly increases secretion of | gonadotropin-releasing hormone (GnRH) |
| In both females and males, the perineum is circumscribed ___________ by the pubic symphysis, ___________ by the ischial tuberosities, and ______ by the coccyx | anteriorly; laterally; posteriorly |
| Match the component of the perineum with the structures that it houses: Clitoris, scrotum | Urogenital triangle |
| Anus | Anal triangle |
| Follicular phase | |
| Ovulation phase | |
| Luteal phase | |
| Ovulation involves the release of the _____________ from a vesicular follicle. | secondary oocyte |
| Normal functions of the uterine tubes | Site for implantation of the pre-embryo; Provide nourishment to the developing embryo |
| Menstrual phase | |
| Secretory phase | |
| Proliferative phase | |
| Breast Anatomy: Location of milk storage | Lactiferous sinus |
| Breast Anatomy: Small, pigmented ring around nipple | Areola |
| Breast Anatomy: Just deep to areolar surface | Areolar glands |
| Breast Anatomy: Cylindrical projection | Nipple |
| The secretory units that produce milk in the lactating female are termed | alveoli |
| Spermatogenesis begins at birth in the human male. | False |
| Male and female external genitalia develop from the same primordial structures. | True |
| During meiosis, homologous pairs of chromosomes can exchange pieces of DNA after they synapse. | True |
| Mitosis involves | a single cell division and results in two diploid cells. |
| DNA replication occurs prior to both meiosis and mitosis. | True |
| The normal chromosome number in a human cell is | 46 (46 chromosomes in a normal human cell; 23 pairs) |
| The internal organs of the female reproductive system include the | ovaries, uterine tubes, uterus, and vagina |
| The uterus serves as the site of implantation for the embryo, supports the developing embryo, and contracts during birth to expel the fetus. | True |
| Ovulation | |
| Mature follicle | |
| Corpus luteum | |
| Secondary follicle | |
| Primary follicle | |
| Before Ovulation | Proliferative phase of uterine cycle; Estrogen low; Rapidly rising LH; Rapidly rising FSH |
| After Ovulation | Progesterone peak; Secretory phase of uterine cycle; Rapidly declining gonadotropins; Menses |
| Before Ovulation | Primordial follicles; First meiotic division; First polar body formation; Mature follicle |
| After Ovulation | Corpus albicans; Second meiotic division completion; Second polar body formation; Second meiotic division begins |
| If a middle-aged woman has gone a year or more without having had her period, she is said to have gone through | menopause |
| Puberty in humans is the result of changes in the ___________, which result in an increased secretion of _________, which then stimulates an increased secretion of __________. | Hypothalamus; GnRH; LH |
| During ovulation, the ________ ruptures and the oocyte enters the uterine tube; later, the empty follicle undergoes structural and biochemical changes and a __________ is formed. | follicle; corpus luteum |
| Primary follicles develop into secondary follicles; one follicle matures and becomes a Graafian follicle. | Follicular phase |
| A secondary oocyte is released from the ovary and enters the uterine tube. | Ovulation |
| The empty follicle becomes a corpus luteum, which secretes estradiol and progesterone. | Luteal phase |
| Occurs while the ovary is in its follicular phase; estradiol stimulates growth of the stratum functionale of the endometrium | Proliferative phase |
| Occurs while the ovary is in its luteal phase; the endometrium becomes thick and more vascularized | Secretory phase |
| Sloughing off of the stratum functionale of the endometrium occurs | Menstrual phase |
| When a primary follicle enlarges, and there are several layers of granulosa cells, it is called a | secondary follicle |
| When of the following has an antrum? | Mature follicle |
| Which of the following is involved in ovulation? | Mature follicle |
| Every human has 23 pairs of chromosomes: 22 pairs of sex chromosomes and 1 pair of autosomes | False |
| Autosomes contain genes for cellular functions, while sex chromosomes consist of either two X chromosomes or an X and ___ chromosome. | Y |
| Gametes from either sex are ________ because they contain 23 chromosomes only, not 23 pairs, and thus their chromosome number is designated as 1n, or just n. | Haploid |
| Which attributes are associated with the process called meiosis? | Produces diploid number of chromosomes |
| During interphase, DNA in each chromosome is replicated in the parent cell and is composed of two identical structures called | sister chromatids |
| The sister chromatids of a replicated chromosome are attached at a specialized region termed the | centromere |
