Human reproduction Flashcards
Acrosome
Structure in the sperm cell that contains enzymes used to penetrate the ovum
Amniotic fluid
the liquid that surrounds the human embryo
blastocyst
a hollow ball of cells into which the fertilised ovum develops
cells of leydig
specialised cells found between the seminiferous tubules that produce the hormone testosterone
chorion
the membrane that forms finger-like projections which grow into the uterine wall
Endometrium
the lining of the uterus which is richly supplied with blood vessels
Epididymis

Implantation
The process by which the embryo becomes attached to the uterine wall

Luteinising Hormone/LH
The hormone which converts the rupture follicle into a corpus luteum
Meiosis
type of cell division by which sperms are produced
Menstrual Cycle
The 28-day reproductive cycle in females involving changes in the ovary and uterus
Menstruation
Tearing away of the endometrium lining of the uterine wall, acompanied by the loss of blood
Mitosis
The cell division by which the zygote becomes multicellular
Estrogen
The hormone which starts the preperation of the lining of the uterus for attachment of the fertilised ovum
Oogenesis
Production of ova by meiosis
Ovulation
Process by which an ovum is released from the ovary in humans
Pituitary Gland / Hypophysis
Gland in the brain that produces FHS and LS
Placenta
Combination of embryonic and material tissue responsible for gas exchange, nutrition and excretion
