Given below is a diagrammatic cross section of a single loop of human cochlea. Which one of the following options correctly represents the names of three different parts?

Options

  1. AB : Tectorial membrane C : Perilymph D : Secretory cells
  2. BC : Endolymph D : Sensory hair cells A : Serum
  3. CD : Sensory hair cells A : Endolymph B : Tectorial membrane
  4. DA : Perilymph B : Tectorial membrane C : Endolymph

Correct answer

D. A : Perilymph B : Tectorial membrane C : Endolymph

Step-by-step solution

Cochlea is the main hearing organ, which is connected with saccule by short ductus reuniens leading from the saccule. It consists of three fluid filled chambers or canals the upper scala vestibuli, lower scala tympani and middle scala media. Both scala vestibuli and scala tympani are filled with perilymph, while scala media is filled with endolymph. The tectorial membrane overhangs the sensory hair in scala media.
