The outer hair cells change length in response to basilar membrane motion. What does that accomplish?
olga nikolaevna [1]

Outer hair cells change their axial dimensions in response to electrical stimulation.

What is basilar membrane motion?

Hair cell stereocilia move as a result of the basilar membrane's movement. The tectorial membrane and the hair cells, which are connected to the basilar membrane, move along with it when it moves, and the stereocilia bend in response to the relative motion of the tectorial membrane.

The hair cells that are linked to the auditory nerve fibers are stimulated by the basilar membrane's movement. While the outside hair cells actively affect the basilar membrane's vibrations, the inner hair cells convert hydromechanical vibration into action potentials.

With each sound cycle, the intracellular voltage of the outer hair cells varies, causing them to lengthen and contract. This increases the organ of Corti's vibration, enabling exceptionally high hearing sensitivity and frequency selectivity.

Because it is difficult to excrete iron once it is in the body, iron balance is maintained primarily through absorption. The iro
Rzqust [24]
<h2>The given statement is true</h2>

Explanation:

Iron absorption occurs in the duodenum and upper jejunum of small intestine

  • At physiological pH ferrous iron is rapidly oxidized to the insoluble ferric form
  • Gastric acid lowers the pH in the duodenum which enhances the solubility and uptake of ferric iron
  • Once iron gets inside the enterocyte it can be stored as ferritin;Ferritin is a hollow spherical protein which helps in storage and regulation of iron levels within the body
  • Ferritin molecule have ferroxidase activity which helps in the mobility of Fe2+ out of the enterocyte by ferroportin
  • Transferrin is the major iron transport protein which transports iron through blood
  • Fe3+ binds to transferrin so Fe2+ transported through ferroportin must be oxidized to Fe3+
  • Fe2+ needs to be oxidized first so that it can be transported through ferroportin
  • Once iron gets inside the cell it can be used for various cellular processes
