Reproduction Systems Flashcards
organs that produce sperm and sex hormones
testes
pouch of skin containing testes. It hangs outside the body to keep the sperm cooler than normal body temperature.
scrotum
sacs containing egg cells
follicles
tiny tubes joining the ovaries to the uterus. Fertilisation occurs in one of these tubes.
fallopian tubes
penetration of the ovum by a sperm
fertilisation
joining together of male and female reproductive cells
sexual reproduction
reproductive cells (sperm or ova) containing half the genetic information of normal cells
gametes
male reproductive cell. It consists of a head, a middle section and a tail used to swim towards the egg.
sperm
female gametes or sex cells. Singular = ovum.
ova
cell formed by the fusion of two gametes; fertilised ovum before it starts to divide into more cells
zygote
reproduction where the egg remains in the female and is fertilised by sperm inserted into the female
internal fertilisation
the act of inserting sperm into the female; also called sexual intercourse or mating
copulation
act of inserting sperm into the female; also called copulation or mating
sexual intercourse
cell division process that results in new cells with half the number of chromosomes of the original cell
meiosis
a new branch of science that involves studying the effect of our experiences on the expression of our genetic information
epigenetics
