Answer:
The correct answer is Option 3 : Epidermal receptors.
Explanation:
Epidermal receptors :
- Located throughout the epidermis, but more plentiful on the body's lateral flanks and ventral surface.
- They are made up of an ovoid tall, slender receptor cell in the epidermis that causes the cuticle to rise.
- Space separates these cells from one another.
- Each cell has a nucleus at various levels and a few basal cells within it.
- The receptor cells' outer ends have a tiny hair-like structure that penetrates the cuticle and extends beyond it.
- At the inner ends of the nerve fibers, there are also linked nerve fibers.
- Some believe they also react to chemical and thermal stimuli, as well as temperature changes.
- As a result, even though earthworms cannot hear, they are extremely sensitive to touch and vibrations transmitted through solid things.
