MCB 246 - FINAL EXAM QUESTIONS WITH
COMPLETE SOLUTIONS
1 spermatogonia and 1 primary spermatocyte Correct Answers
Diploid spermatogonium divides by mitosis to form what?
1. Isthmus
2. Ampulla
3. Fimbriae of indundibulum
Fertilization occurs between ampulla and isthmus Correct
Answers Name these 3 parts of the uterine tube
Where does fertilization occur?
1) Autoregulation - (myogenic response) arteriole diameter
change
2)Autonomic Regulation - sympathetic nervous system
decreases renal blood flow in fight-or-flight state
3) Hormonal Affects - ANP released in response to increase
Atrial Pressure stimulates afferent arteriole dilation Correct
Answers What are the 3 major control systems that regulate
GFR? Name what they do
1) Endothelium of glomerulus
2) Dense layer of glomerulus
3) Podocyte Filtration slits Correct Answers Name the 3 layers
that make up the renal capsule
1) Menstrual phase - (days 1-7) complete loss of the functional
zone of the endometrium -- caused by decrease in estrogen and
progesterone.
, 2) Proliferative phase - (days 7-13) estrogen levels rise as
released from primary follicles, functional zone begins to be
rebuilt
3) Secretory Phase - (days 14-28) - endometrial glands enlarge
as corpus luteum produces progesterone and estrogen, Correct
Answers Know the 3 phases of the uterine cycle, their duration
and the hormones responsible for each.
1) Prostate Gland - slightly acidic (20-30% total)
2) Bulbourethral Gland - thick, alkaline mucous to neutralize
urethral acid and lubricate glans
3) Seminal Vesicle - slightly alkaline, large amounts of fructose
and prostaglandins (smooth muscle contraction) Correct
Answers Name the 3 structures that produces seminal fluid and
the characteristics of their respective fluid?
1) Regulates blood pressure & volume
2) Regulates plasma ion concentrations
3) Regulates acid-base balance Correct Answers Name 3
homeostatic regulator functions of the kidney.
2 haploid secondary spermatocytes Correct Answers 1 primary
spermatocyte divides by meiosis to form?
2-3 degrees Celsius below normal body temp
In hot weather, dartos muscle relaxes and testes move further
away
In cold weather, cremaster & dartos muscles contract and pull
testes closer to the body Correct Answers Proper
