Harvluck B8 W3 Flashcards
Produced by adipose tissue to reduce appetite
Leptin
Redundancy
Molecular signals and neural circuits create a “drive to eat”
Location of ghrelin release?
Enteroendocrine cells in the stomach majorly and episorelin cells in pancreas
Regions with high density to appetite signals
Arcuate and ventromedial hypothalamus and hindbrain
Absence of semen due to retrograde ejaculation
Aspermia
Cause of initial weight loss
Glycogen and water
Temperature for testis to work
35 degrees
Internal factors
Biological factors for food and appetite via hypothalamus signalling
Absence of semen
Azoospermia
Satiety hormone released from intestines
Peptide YY produced by intestinal L cells
Receives projections from the arcuate and ventromedial nucleus of hypothalamus
Paraventricular nucleus
Normal ml of ejaculate produced?
2-5ml
What forms blood testis barrier?
Testosterone from Leydig cells and FSH from primordial germ cells
Populations of neurons in the hypothalamus which control appetite
Melanocortin stimulating hormone- reduce appetite
Neuropeptide Y- increases appetite
Globospermia
Type of teratospermia with abnormal morphology
Variation in these make wieght loss difficult for some
Melanocortin stimulating hormone and neruopeptide Y
GnRH antagonist
Treats prostate cancer
Envrionmental factors for type 2 diabetes
Poor maternal nutrition and thrifty phenotype
Where are acrosomes cap synthesised?
Golgi apparatus
Neuropeptide Y
Released by neurons in the hypothalamus to increase appetite by acting on Y1 and Y5 receptors
Gynoid obesity
Pear shaped look with fat in hips and thighs
