Which statement about extracellular matrix is accurate?

Medicine

Svetach [21]3 years ago
4 0

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.

Otitis media (middle ear infection) is sometimes associated with pharyngitis (sore throat). Explain why this is so.
Ganezh [65]

Answer:

Otitis media is generally caused by dysfunction of the Eustachian tube, which can be due to Pharyngitis.

Explanation:

The otitis media is an infection or inflammation of the middle ear and is mostly caused by the inflammation of the mucous membranes in the nasopharynx leading to dysfunction of the Eustachian tube. This can be caused due to a upper respiratory tract viral infection or streptococcal pharyngitis (strep throat) or due to some allergy.

Pharyngitis or sore throat is a type of inflammation caused by upper respiratory tract viral infection.

Therefore, Otitis media can be caused by Pharyngitis and thus it is associated with it.
