enkephalin-induced depression of single neurons in brain areas with opiate receptors—antagonism by naloxone
kicyunya [14]

Induced depression of single neurons in brain areas with opiate receptors

  • Enkephalin, applied microiontophoretically, depressed spontaneous and glutamate-induced firing of  one neuron in frontal cortex, caudate nucleus, and periaqueductal gray matter, where enkephalin and high concentrations of opiate receptors are met.
  • More than one depressions were blocked by the specific narcotic antagonist naloxone. The results  are durable with a neurotransmitter or neuromodulator role for this new brain pentapeptide.
  • Opium derivatives have been in medical use for the last  2000 years, and may be   longer than any other class of drugs
  • . The brain regions which was  involved in these actions have been identified in some instances by local microinjection of pmole quantities of opioids.

sattari [20]

Answer:

The answer is C, 40,000.

Explanation:

You can obviously tell that 400 is too low... that's one meal for all of the turtles! They would need 40,000 minnows because it's a stable number. They can reproduce, and keep the population up. 4,000, though, is too low because they wouldn't have enough time to reproduce and continue to keep the population alive. Therefore, 40,000 should be a stable population.

The nurse places the stethoscope on the 3rd intercostal space at the left sternal border. Which area is the nurse auscultating f
miv72 [106K]

The nurses auscultated for heart sounds in the area of Erb point.

The fifth point of auscultation for the heart test, known as "Erb's point," which is occasionally given to the eminent German neurologist Wilhelm Heinrich Erb (1840–1921) without any supporting documentation, is positioned in the third intercostal gap near the sternum. At the third intercostal gap and the left lower sternal border is the auscultation location for heart sounds and heart murmurs known as Erb's point.

The spinal accessory nerve in the posterior nerve triangle is located at Erb's point (also known as the great auricular nerve) at the location where it enters the trapezius muscle. At the end of expiration, the third intercostal gap on the left (Erb's point) is often the ideal place to detect the murmur of aortic regurgitation because it is quiet, high-pitched, early diastolic and decrescendo.
