Gonadotropins are released under the control of gonadotropin-releasing hormone ( GnRH ) from the arcuate nucleus and preoptic area of the hypothalamus.
22.
It was found that in these ovariectomized rats there was a significant increase in the number of NKB neurons in the arcuate nucleus.
23.
This included initial release of GnRH . NKB found mostly in the arcuate nucleus in humans, is found mostly in the monkey hypothalamus.
24.
It is synthesised only in neuropeptide Y ( NPY )-containing cell bodies located in the ventromedial part of the arcuate nucleus in the hypothalamus.
25.
Leptin binds to neuropeptide Y ( NPY ) neurons in the arcuate nucleus in such a way as to decrease the activity of these neurons.
26.
The GHRH neurones are located in the arcuate nucleus of the hypothalamus, whereas the somatostatin cells involved in growth hormone regulation are in the periventricular nucleus.
27.
Furthermore, in situ hybridization results from the study showed the highest cellular levels of NPY mRNA in the arcuate nucleus ( ARC ) of the hypothalamus.
28.
And since the thalamic region for the face lies in a separate area called the arcuate nucleus, this explains why the face remains unaffected by referred itch.
29.
The kisspeptin, neurokinin B, and dynorphin cell groups are found to be co-localized to more than 95 % of all of the aforementioned receptors in the arcuate nucleus.
30.
The arcuate nucleus includes several important and diverse populations of neurons that help mediate different neuroendocrine and physiological functions, including : neuroendocrine neurons, centrally projecting neurons, and astrocytes.
