Location: Brain – at the bottom of the third ventricle Tissue Type: Neural Hormone: - Gonadotropin Releasing Hormone (GnRH) - Oxytocin Target Organ/Structure(s): Pituitary Glands

Two Parts: - Anterior - Posterior

Location: Base of the brain; above the roof of the mouth Tissue Type: Oral Ectoderm Hormone(s): - Follicle Stimulating Hormone (FSH) - Luteinizing Hormone (LH) Target Organ/Structure(s): Ovary

Location: Base of brain, under the hypothalamus, behind the anterior pituitary Tissue Type: Neural Hormone(s): - Oxytocin (released from PP) Target Organ/Structure(s): - Mammary Gland (myoendothelial cell) - Myometrium

Location: Lower abdomen Tissue Type: Glandular/Gonadal Hormone(s): - Estrogen Endocrine Structure: Follicle Target Organ/Structure(s): Hypothalamus Function: Increase GnRH - Progesterone Endocrine Structure: Corpus Luteum Target Organ/Structure(s): Hypothalamus Function: Decrease GnRH

Hormone: - Prostaglandin F2α Target Organ/Structure: Ovary, specifically the corpus luteum Function: Lyses it, to restart cycle when no maternal recognition of pregnancy (MRP) occurs (no fertilized ova in uterus)

What are the two cycle types ?: 1) Menstrual 2) Estrus Why two different names?

Menstrual = is calculated from menses to menses, ovulation occurs in the middle of the cycle. (it is what we can see!; humans, primates, etc.) Estrus = is calculated from standing heat to standing heat, ovulation occurs 36 hours later (it is what we can see!; domestic animals)

Primary: Standing to be mounted Secondary: Aids:

Primary: Standing to be mounted Secondary: Mounting other cows; red vulva; Mucous discharge; restless, excitable, bawling Aids: Kamar, Tail paint; Chin Marker, Heat watch

 Storage › Semen Tank (-320 F) › Extenders, Milk or Yolk, and Glycerol (cryopreservent) › 6 ml semen in ejaculate › 1.5 billion sperm/ml › Want million sperm/straw

 Thaw › F in water › 30 – 40 seconds › Dry off straw › Put in gun › Sheath › Cover, put in pants

 Deposition › Insert A.I. gun at 45 degree angle  Be cautious of urethra and bladder › Feed gun through cervix › 5 second deposition

 Donor = Eggs  Recipient = Gestation  Superovulation: › Hormone: Follicle Stimulating Hormone › Atresia versus recruitment

 Recipient – Synchronization › Within 24 hours of donor  Flushing › Saline Solution  Implanting › A.I. Gun
