Answer:
The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid
Explanation:
The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.
- No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.
- ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue <em>does</em> have blood vessels.
- Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.
Answer:
<u>Ethanol prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u>
Explanation:
Ethylene glycol is an organic compound usually used in antifreeze solutions, solvents and cleaners.
It is abused during self-destruction and accidental intakes.
<u>In the body, ethylene glycol is acted upon by alcohol dehydrogenase and is converted into glycolate and oxalate.</u>
Glycolate and oxalate are both nephrotoxic/ kidney damaging substances. Oxalate precipitates calcium oxalate stones in the kidney. Ethylene glycol poisoning also causes high anion gap metabolic acidosis.
In order to prevent ethylene glycol poisoning, the patient is infused with ethanol, ethanol <u>prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u> In this way, ethylene glycol is not metabolized and the formation of nephrotoxic substances is prevented. Alcohol dehydrogenase instead reacts with ethanol to form acetaldehyde.
Answer: (A) Hyperal dosteronism
Explanation:
In the case of hyperaldosteronism the levels of secretion of aldosterone increases. This can become responsible for alkolosis and hyperkalemia. High blood pressure, low levels of potassium, headache, muscle weakness, numbness and feeling tired are the symptoms of the hyper dosteronism. Also the increase in the content of sodium and decrease in levels of magnesium causes polyuria and polydipsia without causing polyphagia.
Answer:
La definición de salud de la OMS establece que la salud no es solo la ausencia de enfermedad sino que también es estar bien mentalmente, físicamente y socialmente. Esta definición no abarca solo curar a una persona cuando esté enferma, también habla sobre la prevención de la enfermedad manteniendo una vida equilibrada en lo que concierne a lo físico, mental y social.
La definición de salud de la OPS es mucho más estrecha. Esta solo incluye la adaptación de la persona a su medio, lo cual si lo comparamos con la definición de la OMS este concepto podría entrar dentro del bienestar físico, mental y social. Podemos ver que no se refiere específicamente a la enfermedad y que la ausencia de esta sería por una adaptación exitosa de la persona. A su vez la adaptación es una forma de prevenir la ausencia de salud según la definición de la OPS.
Explanation:
La Organización Mundial de la Salud y la Organización Panamericana de la Salud. son dos entidades que se especializan en la salud a nivel internacional. La OPS actualmente forma parte de la OMS ya que es una oficina para la región americana de la OMS. Estas dos organizaciones empezaron por separado y tienen definiciones de salud diferentes pero podemos ver que ambas trabajan para prevenir y curar enfermedades.
