SLS Bio12 Reproducti
SLS Bio12 Reproduction AV
| Term | Definition |
|---|---|
| Acrosome | A membrane-bound compatment at the tip of the head of a sperm which contains lytic enzymes (hyaluronidase in mammalian sperm) which digest the outer surface of the egg and allow the sperm to inject its haploid dna |
| Anterior Pituitary | The front portion of the pituitary, a small gland in the head called the master gland. Hormones secreted by the anterior pituitary influence growth, sexual development, skin pigmentation |
| Cervix | The cervix is the lower, narrow part of the uterus (womb). The uterus, a hollow, pear-shaped organ, is located in a woman's lower abdomen, between the bladder and the rectum |
| Clitoris | A small mass of erectile tissue situated at the anterior apex of the vestibule |
| Corous Luteum | A yellow glandular mass in the ovary formed by an ovarian follicle that has matured and discharged its ovum |
| Cowper's Glands | Either of two small glands of which one lies on each side of the male urethra below the prostate gland and discharges a secretion into the semen |
| Ductus Vas Deferens | The excretory duct of the testis that conveys sperm. A duct that carries spermatozoa from the epididymis to the ejaculatory duct |
| Endometrium | The tissue lining the uterus, it is sloughed off during the woman's menstrual period, and afterward grows back and slowly gets thicker and thicker until the next period |
| Epididymis | Convoluted tubule connecting the vas efferens, that comes from the seminiferous tubules of the mammalian testis, to the vas deferens. Maturation and storage of sperm occur in the epididymis |
| Estrogen | A general term for female steroid sex Hormones that are secreted by the ovary and responsible for typical female sexual characteristics |
| Follicles | A small secretory cavity, sac, or gland, in particular |
| FSH | An acidic glycoprotein secreted by the anterior pituitary gland. In women, follicle-stimulating hormone stimulates the development of ovarian follicles (eggs) and stimulates the release of oestrogens. |
| HCG | Begins on Day 1 of your menstrual cycle. Day 1 is by definition the day your period starts. The follicular phase ends when a hormone called luteinizing hormone peaks and ovulation occurs. |
| Hypothalamus | A hormone that is produced by the developing placenta and by the fertilized egg after implantation in the uterine wall |
| Implantation | The hypothalamus is also involved in the regulation of body temperature, water balance, blood sugar and fat metabolism |
| Interstitial Cells | The insertion or grafting into the body of biological, living, inert or radioactive material |
| Luteal Phase | A cell that occurs between the germ cells of the gonads and that may furnish the male sex hormone. Also called Leydig cell |
| Lutenizing Hormone | The post-ovulatory phase of a woman's cycle, the corpus luteum produces progesterone, which in turn causes the uterine lining to secrete substances to support the implantation and growth of the early embryo |
| Menstruation | A type of hormone produced by the anterior pituitary gland of the endocrine system. In females, this pro |
| Midpiece | The cyclic, physiologic discharge through the vagina of blood and mucosal tissues from the nonpregnant uterus, it is under hormonal control and normally recurs, usually at approximately four week intervals |
| Ovarian Cycle | The middle piece of the spermatozoon is a highly organized segment consisting of MITOCHONDRIA, the outer dense fibers and the core microtubular structure |
| Ovaries | the sequence of physiologic changes in the ovary involved in ovulation |
| Oviducts | One of two small oval bodies situated on either side of the uterus on the posterior surface of the broad ligament |
| Ovulation | Any of the pair of ducts or tubes in female reproductive organ through which an ovum passes from the ovary to the uterus (as in mammals) or to the outside (as in oviparous animals) |
| Oxytocin | The discharge of a secondary oocyte from a vesicular follicle of the ovary. The expulsion of an ovum from the ovary (usually midway in the menstrual cycle).The formation of female |
| Penis | a hormone released by the pituitary gland that causes increased contraction of the uterus during labor and stimulates the ejection of milk into the ducts of the breasts |
| Positive Feedback Mechanism | The male organ of copulation and of urinary excretion, comprising a root, body and extremity or glans penis |
| Progesterone | An example of positive feedback loop is the onset of contractions in childbirth. When contraction begins, the hormone oxytocin is released into the body to stimulate further contractions |
| Proliferative Phase | Produced in the corpus luteum, as an antagonist of oestrogens |
| Prostate Gland | the phase of the menstrual cycle after menstruation. Under the influence of follicle-stimulating hormone from the pituitary, the ovary produces increasing amounts of estrogen |
| Scrotum | A gland in the male that surrounds the neck of the bladder and urethra |
| Secretory Phase | A muscular sac which contains the testes |
| Seminal Fludi | semen: the thick white fluid containing spermatozoa that is ejaculated by the male genital tract |
| Seminal Vesicles | each of a pair of glands that open into the vas deferens near its junction with the urethra and secrete many of the components of semen. |
| Seminiferous Tubules | any of the numerous long convoluted tubules in the testis which are the sites where spermatozoa mature |
| Sperm | male reproductive cell |
| Tail | The part of the sperm responsible for motion |
| Testes | an organ that produces spermatozoa (male reproductive cells). |
| Testerone | a steroid hormone that stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex. |
| Urethra | the duct by which urine is conveyed out of the body from the bladder, and which in male vertebrates also conveys semen. |
| Urethral Opening | The opening of the urethra, leading to the environment outside the body |
| Uterine Cucle | The changes that occur in the uterus during the reproductive cycle of the human female; also called the menstrual cycle. |
| Uterus | the organ in the lower body of a woman or female mammal where offspring are conceived and in which they gestate before birth; the womb. |
| Vagina | the muscular tube leading from the external genitals to the cervix of the uterus in women and most female mammals. |
