What neurons of the supraoptic nuclei of the hypothalamus manufacture?
CRF and GnRH
What is the structure that join two area to posterior pituitary?
1. supraoptic area 2.para ventrical
What are the four parts of the hypothalamus?
optic part, which contains 2 nuclei = supraoptic + paraventricular nucleituberal part, has 3 nuclei = ventromedial + dorsomedial + tubral nucleimamillary part, has 2 nuclei = posterior + lateral nucleiposterior perforated substance
Where are adh and Oxycontin synthesized?
The posterior pituitary also known as the neurohypophysis contains nerve endings of tracts that originate in the hypothalamus. The two "nuclei" that supply these tracts are the Paraventricular and Supraoptic. The primary secretion of the paraventricular nucleus is OXYTOCIN. The primary secretion of the supraoptic nucleus is ADH also known as Vasopressin. Even though these nuclei have a "primary" secretion, each nucleus can synthesize approximately 1/6th of the other hormone that is not it's primary secretion. The best way to remember is the acronym POSA(paraventricular-oxytocin/supraoptic...Source:Textbook of Medical Physiology, Guyton
Adh is produced where?
ADH is produced by the hypothalamus in the brain. It is then transported to the nearby pituitary gland and is then released for use in the body.
Where are the anterior supraoptic recess and the infundibular recess?
The third ventricle contains two saclike recesses called the anterior supraoptic recess and the infundibular recess
What is multiple small hypo densities seen in bilateral fronto-parietal subcortical and periventricular white matter?
Small hypo densities are seen in bilatereral para ventricular region
What is para and ortho hydrogen?
A molecule of diatomic hydrogen (hydrogen gas) contains two hydrogen atoms. The nucleus of each aton (a protron) is spinning. Depending upon the direction of the spin of the two nuclei, the hydrogens are of two types: ortho or para. Ortho-hydrogen molecules are those in which the spins of both the nuclei are in the same direction. Para-hydrogen is when the spins of both the nuclei are in the opposite directions. Ordinary hydrogen gas is an equilibrium mixture of ortho and para hydrogen. The amount of ortho- and para-hydrogen varies with temperature. At 0°K, hydrogen contains mainly para-hydrogen which is more stable. At the temperature of liquid of air, the ratio of ortho- and para-hydrogen is 1 : 1. At the room temperature, the ratio of ortho- to para-hydrogen is at its maximum of 3 : 1. Even at very high temperatures, the ratio of ortho- to para-hydrogen can never be more than 3 : 1. So, it is possible to get pure para hydrogen by cooling ordinary hydrogen gas to a very low temperature (close to 20 K) but it is never possible to get a sample of hydrogen containing more than 75% of ortho hydrogen.
What does inadequate ventricular systole mean?
It is a defective ventricular contraction.
What does a ventricular shunt relieve?
A ventricular shunt relieves hydrocephalus
Does ventricular pressure increase the fastest during ventricular filling?
yes
When does Isovolumetric relaxation and ventricular filling take place?
Ventricular Diastole
