The fertilized egg is known as a ________
Zygote
_______ tissue in the penis fills during arousal
Eractile
Paired tubes which carry sperm from the testes to seminal vesicles
Vas deferens
__________ cells are responsible for the production of testosterone
Interstitial
The inner portion of the labia is known as the labia _________
Minora
Found at the top of the vagina, this is the opening to the uterus
Cervix
There are large numbers of mitochondria in the ________ of a sperm
Midpiece
A skin sac which contains the testes
Scrotum
This hormone is released by the hypothalamus which causes the anterior pituitary gland to release LH and FSH
GnRH
A structure attached to the side of the testicle which contains numerous tubules
Epididymis
Breast milk contains numerous _______ which can help protect newborns from various diseases
Antibodies
The production of oxytocin during labour is an example of a ______ feedback system
Positive
Location of erectile tissue in females; contains many nerve receptors; analogous to the penis in males
Clitoris
The follicle which releases an egg from the ovary turns into the _______ luteum which begins releasing hormones
Corpus
The name of the fluid which is ejaculated from the penis
Semen
The birth canal; also a receptacle for the penis during copulation
Vagina
The ______ gland secretes an alkaline fluid into the semen
Prostate
The seminiferous tubules are so long in order to increase the _______ for development of large numbers of sperm
Surface area
The female sex cell
Egg
This hormone is released by the anterior pituitary and causes the sex organs to release either the male or female sex hormones
LH
A tube leading from the bladder to the outside environment
Urethra
The _______ phase occurs second in the menstrual cycle - when the corpus luteum is releasing hormones
Luteal
Also known as the fallopian tube, this structure leads from the ovary to the uterus
Oviduct
Mothers produce ______ to feed their newborn babies
Milk
The release of the lining of the uterus during the first days of the female cycle
Menstruation
A structure which can be stimulated to produce sperm or eggs
Follicle
The female hormone which dominates in the latter portion of the menstrual cycle
Progesterone
The ______ phase of the menstrual cycle occurs first; this is when a follicle is developing in an ovary
Follicular
The female hormone which dominates in the early part of the menstrual cycle
Estrogen
The ______ tubules are the location of spermatogenesis
Seminiferous
The male sex cell
Sperm
These glands provide milk to the newborn baby
Mammary
_______ is produced by the breasts in the first couple of days of breast feeding - it contains more protein and less fat than milk
Colostrum
A collective term referring to all of the external female genitalia
Vulva
Organ used for the storage of urine
Bladder
The lining of the uterus
Endometrium
As sperm levels in the testes rise, this hormone is produced by the Sertoli cells which acts on the hypothalamus
Inhibin
These finger-like structures waft the egg cell from the ovary duct into the oviduct
Fimbriae
This hormone is responsible for uterine contractions during labour and milk production post-partum
Oxytocin
Rhythmic contractions of smooth muscle in vessels (eg. vas deferens) to propel material through those vessels
Peristalsis
This hormone, secreted by the anterior pituitary, is responsible for initiating the production of either sperm or eggs
FSH
Both sperm and eggs are haploid because they were formed via the process of ______
Meiosis
The hormone ______ is responsible for maintaining hormone levels to prevent menstruation during pregnancy
HCG
These cells help to “nanny” or “nurse” sperm along to full maturity
Sertoli
The ______ gland secretes a slippery fluid sometimes referred to as pre-ejaculate
Cowpers
Hormones which cause the uterus to contract
Prostaglandins
Sometimes called the womb - this is where the fetus develops
Uterus
An organ which forms in the uterus during pregnancy
Placenta
The female sex organ which produces eggs and hormones
Ovary
The expulsion of semen from the penis
Ejaculation
The release of an egg on day 14 of the cycle due to a surge in luteinizing hormone
Ovulation
The ejaculatory ______ carries semen from the seminal vessicles to the urethra
Duct
______ muscle is found in the various tubules to propel their contents
Smooth
The male copulatory organ
Penis
A membrane which may cover the opening of the vagina
Hymen
The uniting of the nuclei of a sperm and an egg is considered the moment of ______
Conception
Inhibin being produced as sperm quantities increase in the testes is an example of a _______ feedback system
Negative
This substance fills the penis and clitoris during arousal
Blood
The location of sperm and testosterone production
Testes
In order to mature properly, sperm must form in an environment that is _______ than the normal internal body temperature
Cooler
The typical female menstrual cycle lasts ______ days
28
