kherson [118]

This insulin has no peak action and does not cause a hypoglycemic reaction.

<h3>What is insulin?</h3>
  • Insulin is a peptide hormone generated by beta cells of the pancreatic islets and is encoded by the INS gene in humans.
  • Its name is derived from the Latin insula, which means "island." It is regarded as the body's primary anabolic hormone.
  • It promotes the uptake of glucose from the circulation into liver, fat, and skeletal muscle cells, which controls the metabolism of carbs, lipids, and protein.
  • The ingested glucose is transformed in these tissues into either glycogen (through glycogenesis) or fats (triglycerides), or, in the case of the liver, both, via lipogenesis.
<h3>What is the insulin's source?</h3>
  • The pancreas, an organ behind the stomach that produces the hormone insulin, is responsible for this.
  • The pancreas contains specific regions known as the islets of Langerhans (the term insulin comes from the Latin insula that means island).

Which statement about extracellular matrix is accurate?
Svetach [21]

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.
