Week 10 Homework - Reproduction Flashcards
Which process produces polar bodies?
Oogenesis
Which hormones are NOT likely going to elevate during menopause?
Estrogen
What hormone from the hypothalamus helps to regulate the production of testosterone in the testicles?
Gonadotropin releasing hormone (it’s in the name ‘gonads’)
Where are the seminiferous tubules located?
The testicles
Which process initiates before birth and only concludes upon fertilization?
Oogenesis
Which process produces cells requiring further specialization before they can perform their needed role in reproduction?
Spermatogenesis
Which process allows growth, development in utero, repair or replacement of old or damaged cells?
Mitosis
If you cross a heterozygous and homozygous recessive individual for an autosomal trait, what percent of individuals would be expected to display the dominant phenotype?
50%
Which process produces cells that can self-propel?
Spermatogenesis
What hormone stimulates ovulation?
Luteinizing hormone
Which process is the same regardless of sex?
Mitosis
Identify one of the structures that stores mature sperm prior to ejaculation?
Vas (ductus) deferens
Ducts store
Where are cilia located in the reproductive system?
Uterine tube
When testes fail to descend into the scrotum the condition is known as…
Cryptorchidism
At what level of sperm production could an individual struggle with fertility problems?
20 million sperm per 3 ml of ejaculate.
Which of the following terms would not be an appropriate descriptor of an egg or sperma.
a.Gamete.
b. Spermatogenesis and oogenesis are sex specific processes.
c. Haploid.
d. Possessing 23 chromosome pairs.
e. Created through meiosis.
Possessing 23 chromosome pairs
(just 23 chromosomes…they are haploid)
What structure supplies the enzymes needed to activate the sperm in the ejaculate?
Prostate
(Protein, which is what enzymes are)
What component of the nervous system controls the process of erection?
Parasympathetic nervous system
What hormones are produced by the corpus luteum?
estrogen and progesterone
How do you represent a female that is heterozygous for a sex-linked trait?
XAXa
When are estrogen levels highest?
Within the middle of the cycle from day 10 to 16 of the uterine cycle.
Identify the first phase of the ovarian cycle.
Follicular
(then Ovulation, then Luteal)
What structure supplies the fructose to the ejaculate necessary for sperm energy?
Seminal vesicles
(semen fed by fructose)
Which form of non-disjunction error is most likely to be fatal when it impacts an autosomal chromosome (chromosomes 1-22 instead of chromosome 23).
a. Trisomy where an individual has too much genetic informaiton.
b. Monosomy where an individual has too little genetic information.
Monosomy
Identify the phase of the uterine cycle when estrogen and progesterone production increases.
Secretory
Examine an image of the female reproductive system and identify the structure that extends closest to the ovaries.
a. Ampulla.
b. Infundibulum.
c. Oviduct.
d. Fimbriae.
e. Fundus.
Fimbriae
What hormone becomes a unique marker of pregnancy?
Human chorionic gonadotropin
When are homologous chromosomes separated?
Meiosis 1
(sister chromatids during Meiosis 2)
What structure supplies the lubrication during intercourse?
Bulbourethral gland
