|
|
Term
|
Definition
sexual stimulation --> parasympathetic nerve impulses from sacral portion of the cord --> sexual stimulation intesifies-->vestibular glands secrete mucus to lubricate--> orgasm - rhythmic contraction of muscles of the perineum; muscular walls of uterus and uterine tubes contract sexual stimulation --> parasympathetic nerve impulses --> tissues dilate; vagina expands/elongates --> swollen/engorged vagina increases friction from movement of penis |
|

|
Definition
labia minora swells grandular cells lining labia minora secrete fluid |

(female)excitement stage clitoris |
|
Definition
engorgement prepuce will appear more visible above tissue can feel ridge |
|
|
Term
|
Definition
clitoris retracts cervice extends further down vagina uterus moves - sits upward vagina bulges out and forms the orgasmic platform - grasps penis tighter |
|
|
Term
|
Definition
small amount of fluid can be ejected through the urethra buldging out of vagina can be filled with secretory fluid and semen which can accumulate and be expelled |

3 different types of orgasms uterine vaginal g spot basically just different types of stimulation |
|
|
Term
|
Definition

|
|
Term
| female nipples excitement phase |
|
Definition
breast size increase nipple becomes erect veins become more visible |
|
|
Term
| nipples plateau and orgasm phase |
|
Definition
nipples become less erect "sex flush" can occur breast increases still more in size |
|
|
Term
| resolution phase nipples female |
|
Definition
sex flush disappears rapidly breast size returns to normal size |
|
|
Term
|
Definition
vasocongeestion results in erection meatus (tip of penis) dilates testes begin elevation |

|
Term
|
Definition
cowper's gland may release fluid (bulbourethral) testes have fully risen |
|
|
Term
|
Definition
| emission - rhythmic compressions of vas deferens and seminal vesicles results in collection of sperm and semen into urethra and ejaculated through rhythmic contractions of urethra. |
|
|
Term
| 4 stages of sexual response cycle |
|
Definition
excitement plateau orgasm resolution |
|
|
Term
|
Definition
head - acrosome cap, head midpiece -neck (centriole) tail - flagellum |
|
|
Term
|
Definition
| contains the nucleus 22 autosomes and 1 sex chromosome |
|
|
Term
|
Definition
| contains enzymes that help penetrate ovum |
|
|
Term
|
Definition
| contains centriole which is used to form the spindle in the zygote |
|
|
Term
|
Definition
contains mitochondria which uses lots of ATP generates energy for tail movement |
|
|
Term
|
Definition
| allows sperm to swim up the reproductive tract |
|
|
Term
|
Definition
| conversion of connected spermatids into mature sperm. see slide |
|
|
Term
|
Definition
| the bridges that connect spermatids |
|
|
Term
|
Definition
1 embryo consists of PGC's which are multiplying in ovaries 2 the rest stay in meiosis I in ovary once you hit puberty, you get maturation of primary oocytes. the oocyte has an egg coat and cortical granules 3 ovulation you get secondary oocyte cells are haploid but chromosomes are replicated so must have fertilization for meiosis II --> polar body is formed |
|
|
Term
|
Definition
polar body cast off into area where sperm enter which then bind to ovum membrane |
|
|
Term
|
Definition
| A matrix of 3 glyco proteins ZP1, ZP2 ZP3 |
|
|
Term
| Cumulus Oophorus aka Corona Radiata |
|
Definition
Part of ovum/ secondary oocyte which cinsists of 2-3 layers of follicular cells purpose - to provide protection and vital proteins to the cell |
|
|
Term
| post ejaculated sperm route |
|
Definition
| Vagina -> Cervix -> Uterus -> oviduct -> ampullary-isthmic |
|
|
Term
|
Definition
thermotaxis - sperm are attracted towards heat chemo taxis - movement towards a chemical signal |
|
|
Term
|
Definition
| causes an invasion of white blood cells into the uterine lumen, these cells engulf dead/dying sperm |
|
|
Term
|
Definition
When initially in the female reproductive tract, sperm cannot fertilize eggs. Modification of glycoproteins and hyperactivation of sperm tail |
|
|
Term
| fallopian tubes (cilia) function |
|
Definition
cilia in the ovidcut have 2 ways of movement cilia at ridges beat towards the uterus cilia in groves beat twoards the ovary (sperm tend to swim in the grooves) |
|
|
Term
|
Definition
| enzyme on the sperm head that breaksdown |
|
|
Term
|
Definition
| found in connective tissue and acts like glue to hold cells together |
|
|
Term
| acrosome reaction is trigged by |
|
Definition
| ZP3 binds a receptor on the sperms plasma membrane |
|
|
Term
|
Definition
Sugars on ZP3 are bound by GaIT on the surface of sperm ZP3 on egg surface induces aggregation of GaIT on the surface of the sperm head A G Protein cascade is triggerred and exocytosis of the acrosome ensues |
