Question

pacinian corpuscles are mechanoreceptors that are sensitive to deep pressure and vibration. where are they predominantly found?
answers: a - e
a hypodermis
b connective tissue
c dermis
d sub q
e epidermis

Explanation:

Pacinian corpuscles are large, encapsulated mechanoreceptors. They are predominantly found in the hypodermis (also known as the subcutaneous tissue). This layer is beneath the dermis. The hypodermis contains adipose tissue and connective tissue. Pacinian corpuscles are sensitive to deep - pressure and vibration stimuli. They have a unique structure with multiple concentric layers of connective tissue (like an onion - like structure) around a nerve ending. The dermis contains other types of mechanoreceptors (e.g., Meissner's corpuscles for light touch). The epidermis is avascular and mainly composed of keratinocytes with no such large encapsulated mechanoreceptors. Connective tissue is a broad category (the hypodermis itself has connective tissue, but the specific location is the hypodermis layer). "Sub Q" is an abbreviation for subcutaneous (which is the hypodermis, but the proper anatomical term for the layer is hypodermis).

Answer:

A. Hypodermis
