Question

describe 5 different senses in animals that depend on mechanoreceptors. describe how the receptors are arranged to produce a particular sense for each of them

Answer 1

Ans .Mechanoreceptors detect stimuli such as touch, pressure, vibration, and sound from external and internal environments. They contain primary sensory neurons that respond to changes in mechanical displacement, usually in a localized region at the tip of a sensory dendrite.

1) Tactile corpuscles ( meissner corpuscles) respond to light touch and adapt rapidly to changes in texture (vibrations around 50Hz).

2) Bulbous corpuscles (Ruffini endings) detect tension deep in skin and fascia

3) Merkel nerve endings (merkel discs ) detect sustained pressure

4) Lamellar corpuscles ( pacinian corpuscles) in the skin and fascia detect rapid vibrations (of about 200-300 Hz).

5) Cutaneous mechanoreceptors respond to mechanical stimuli that result from physical interaction, including pressure and vibration.
