12 Questions
What are the four major events of the follicular phase?
- Elevated GnRH secreted from anterior pituitary, 2. Follicular growth and preparation for ovulation, 3. Sexual receptivity, 4. Ovulation
What are the cardinal signs of inflammation?
- Heat (due to vasodilation), 2. Redness (vasodilation), 3. Swelling (influx of plasma proteins), 4. Pain (due to local release of enzymes and increased pressure), 5. Loss of function
True or false: Follicular pressure increases and follicle walls weaken when PGE2 and PGF2alpha increase.
True
What is measured for ovulation detection?
LH surge
What is the site of follicular rupture?
Stigma
True or false: induced ovulators have short copulation times and low copulation frequency.
False
What is the purpose of a CIDR device and how does it work?
The purpose of a CIDR device is to release progesterone intravaginally to synchronize estrus. It works by providing controlled intravaginal drug release of 1.35g progesterone, which is removed on the 7th day.
How does Lutalyze accelerate estrus?
Lutalyze accelerates estrus by inducing luteolysis of the Corpus Luteum (CL), causing a decline in progesterone levels which in turn increases GnRH and gonadotropins to resume estrous cycling.
What are two ways to acquire active immunity?
Active immunity can be acquired naturally through exposure to a pathogen leading to disease and immune response, or through vaccination.
How does Spayvac work?
Spayvac works by injecting porcine Zona Pellucida (ZP) antigens which bind to adjuvant, triggering an immune reaction in females. This reaction leads to the production of PZP antibodies that target the female's own eggs, preventing sperm binding and fertilization.
What is the purpose of Gonacon and how does it work?
Gonacon decreases sexual activity in males and females by decreasing GnRH levels in both genders. This decrease in GnRH results in lower production of steroid hormones (Testosterone/Estrogen) which reduces sexual behavior.
What are the major events of the luteal phase?
The major events of the luteal phase include the formation of the Corpus Luteum (CL) through luteinization during metestrus, and the production of progesterone.
