Answer:
As part of the development of the neural tube, by the sixth week of embryonic development, the brain vesicles are already formed.
Explanation:
The encephalic vesicles correspond to a group of dilations that will give rise to the brain and its related structures.
Around the 4th week of embryonic development, the primary encephalic vesicles are formed, and by the 6th week there will also be secondary encephalic vesicles, for a total of five divisions.
The five encephalic vesicles formed in week 6 of embryonic development are the myelencephalon, metencephalon, midbrain, diencephalon and telencephalon.
- <em><u>myelencephalon
</u></em>: It is the structure that is organized to form the spinal bulb, in addition to the motor nuclei of the cranial nerves (pairs) IX to XII.
- <u><em>Metencephalon</em></u>
: It gives rise to the cerebellum and the protrusion.
- <em><u>Midbrain</u></em>
: It forms important structures such as the Edinger-Westphal nucleus, the wing plates, the tegment - together with the nuclei of the cranial nerves III and IV - and the upper cerebellar pedicles.
- <u><em>Diencephalon</em></u>: gives rise to the Thalamus, hypothalamus and pituitary gland.
- <em><u>Telencephalon</u></em>: originates the structure of each cerebral hemisphere, besides the striated body and its respective divisions in caudate and lenticular nuclei.
Because you are taking things that don't belong to you without asking.
No, it's because we need to breathe. Your body needs oxygen. Air pressure has little to nothing to do with it as far as I know.
Answer:
A. Assess the client's level of pain and administer prescribed analgesics.
Explanation:
The cardinal or major symptom of myocardial infarction (MI) is persistent, crushing substernal pain or pressure. Therefore nurse should first assess the client's pain and prepare to administer anagelsics like, Nitroglycerin or Morphine for pain control. The Nurse must ensure that the client is medically stabilized before pulmonary artery catheterization can be used as a diagnostic procedure. Anxiety and a feeling of impending doom are characteristic of MI, but the priority is to stabilize the client medically. Don't forget to inform the client and his family about every step of the recovery process, this action isn't really of top priority when treating a client with a suspected MI.
