Question

Cells of Deiter occur in
A. Retina
B. Organ of Corti
C. Utriculus
D. Sebaceous glands

Answer 1

Cells of deiter are also known as phalangeal cells or deiter cells that are found within the inner ear. The function of these cells is to hold the base of the hair cell in a cup-shaped depression and contributes to hearing. It consists of three parts: 1) the cell body, 2) the straight phalangeal process, 3) the head of the phalangeal process.

Complete answer:

Option A- Retina
The retina is the innermost sensitive layer of tissue that lines the back of the eye which is located near the optic nerve. The function is to receive the light that the lens has focussed forming an image, which is then converted and the neural impulses are forwarded to the brain for visual configuration.

Option B- Organ of Corti
The organ of Corti is a structure of the inner ear that is located within the cochlea and is also known as the receptor organ for hearing. It includes three rows of outer hair cells and one row of inner hair cells.
The primary function is the transduction of auditory signals.

Option C- Utriculus
The utricle is a part of the membranous labyrinth which is a small membranous sac, paired with a saccule located within the vestibule of the inner ear. The main function of these otolith organs is orientation and static balance of the body.

Option D- Sebaceous glands
Sebaceous glands are exocrine glands in the skin that secrete an oily and waxy substance called sebum which lubricates the hair as well as the skin of mammals.

Thus, the correct option is option B- Organ of Corti.

Note: The hair cells on the organ of Corti held by Deiter cells, have stereocilia that are tiny projections that bend as the sound vibrations reach the inner ear and the cochlear fluid moves. This causes the conversion of motion into electrical signals that reach to the brain through nerve cells via neurotransmitters. Hence, the mechanism of hearing.
