Which integumentary structure is responsible for the sensation of touch and pressure?
Meissner's corpuscles
Hair follicles
Nails
Sebaceous glands
The Correct Answer is A
A. Meissner’s corpuscles: Meissner’s corpuscles are specialized sensory receptors located in the dermal papillae that detect light touch and pressure.
B. Hair follicles: Hair follicles anchor hair shafts and may have nerve endings for hair movement detection but are not primary touch receptors.
C. Nails: Nails protect the fingertips and enhance fine touch sensitivity but do not directly detect pressure.
D. Sebaceous glands: Sebaceous glands secrete sebum to lubricate skin and hair, not to sense touch or pressure.

Correct Answer is A
Explanation
A. Dermis:The dermis contains blood vessels and many inflammatory responses that produce redness and swelling and is involved when inflammation extends below the epidermis.
B. Hypodermis:The hypodermis (subcutaneous layer) contains adipose tissue and larger vessels; involvement here indicates deeper inflammation than what is described as superficial.
C. Subcutaneous tissue:Subcutaneous tissue is synonymous with the hypodermis and indicates deeper involvement rather than a superficial process.
D. Epidermis:The epidermis is the most superficial layer of the skin and is affected in superficial inflammatory conditions such as dermatitis or mild contact irritation.
Correct Answer is B
Explanation
A. Sebum secretion:Sebum lubricates and waterproofs skin but does not play a significant role in thermoregulation.
B. Sweat evaporation:Evaporation of sweat from the skin surface removes heat and is a primary means of cooling the body.
C. Production of melanin:Melanin protects against UV radiation but does not directly regulate body temperature.
D. Keratin production:Keratin provides structural protection for skin and appendages but is not a thermoregulatory mechanism.
