2009 Lab 1
Cell Division and Fertilization
Introduction
This laboratory will look at gametogenesis and fertilization. As this is your first laboratory, it will also introduce the online embryology learning materials that support your learning objectives.
The laboratory will also introduce individual progressive assessment and the group online assessment submission.
Objectives
- Identify the anatomical structure of the testes and the ovary.
- Identify the stages and differences between gamete development in the two gonads.
- Understand the endocrine regulation and changes associated with the menstrual cycle.
- Understand the process of fertilization.

Terms
oocyte
(Greek, oo = egg, ovum) The term used to describe the haploid egg or ovum formed within the ovary (female gonad) and released to enter the uterine tube and be transported to the [U.htm#uterus uterus]. The mature oocyte is the cell released from the ovary during ovulation.
(More? Week 1 - Oogenesis)
oogenesis
(Greek, oo = egg + genesis = origin, creation, generation) process of diploid oogonia division and differentiation into an haploid oocyte (egg) within the ovary (female gonad). Mammalian meiosis will only be completed within the oocyte if [F.htm#fertilization fertilization] occurs.
(More? Week 1 - Oogenesis)
oogonia
(Greek, oo = egg) diploid germ cells within the ovary (female gonad) which provide the primary oocytes for oocyte (egg) formation. In humans, all oogonia form primary oocytes within the ovary before birth.
(More? Week 1 - Oogenesis)
oophorus
(Greek, oo = egg + phorus = carrying, egg-bearing) cumulus oophorus, used to describe the granulosa cells within the follicle that tether or link the oocyte to the wall of the follicle.
(More? Week 1 - Oogenesis)
ovarian factor
A cause of infertility due to problems with egg production by the ovaries.
(More? Week 1 - Oogenesis)
ovarian hyperstimulation syndrome
(OHSS) Condition associated with fertility drugs for in vitro fertilization and other reproductive abnormalities.
(More? Week 1 - In Vitro Fertilization | Medlineplus - OHSS)
ovarian monitoring
The use of ultrasound and/or blood or urine tests to monitor ovarian follicle development and hormone production.
(More? Week 1 Notes | Week 1 - Oogenesis)
ovarian stimulation
The use of drugs to stimulate the ovaries to develop follicles/eggs. (More? Week 1 - Oogenesis | Human Menstrual Cycle)
oviduct
(uterine horn, fallopian tube, oviduct, salpinx) see [#uterine_tube uterine tube]. A pair of tubular structures designed to transport the oocyte (egg) from the ovary to the [U.htm#uterus uterus] body.
(More? Week 1 - Oogenesis | Week 1 Notes | Blue Histology - Female Reproductive System)
ovulation
The term used to describe the process of the mature follicle releasing the oocyte or ovum (and support cells) from the ovary surface into the peritoneal cavity. In humans, generally a single oocyte is released from a cohort of several maturing follicles. More than one follicle may be released (superovulation) following reproductive therapeutic treatment.
(More? Week 1 - Oogenesis | Week 1 Notes)
testes
(Latin testis = "witness") The two male gonads (singular testis) where male germ cells (spermatozoa) are generated and also the source of testosterone (male hormone). Embryonically formed from primordial germ cells entering region of the paired mesonephric ducts (Wolffian ducts) which are preserved in male gonad development and lost in females.
(More? Genital System - Male)
testis
(Latin testis = "witness", plural testes) The male gonad where male germ cells (spermatozoa) are generated and also the source of testosterone (male hormone). Embryonically formed from primordial germ cells entering region of the paired mesonephric ducts (Wolffian ducts) which are preserved in male gonad development and lost in females.
(More? Genital System - Male)
testis-determining factor
(TDF, Sry, Testis-Determining Factor on Y, TDY ) Protein name for the protein transcription factor product of the Sry gene on the Y chromosome responsible for maleness. This protein is a member of the high mobility group (HMG)-box family of DNA binding proteins. See also the transcription factor SRY-related protein, SOX9 (SRY-related high-mobility group (HMG) box 9)
