Which layer of the skin contains blood vessels, sensory receptors, and glands?

A. Osteoarthritis:Osteoarthritis involves progressive wear and tear of articular cartilage, resulting in joint pain, stiffness, and decreased range of motion.
B. Bursitis:Bursitis is inflammation of a bursa (fluid-filled sac) causing localized pain and swelling but does not primarily involve cartilage degeneration.
C. Rheumatoid arthritis:Rheumatoid arthritis is an autoimmune inflammatory synovitis that can secondarily damage cartilage, but its hallmark is systemic synovial inflammation rather than primary degenerative cartilage loss.
D. Gout:Gout is characterized by deposition of monosodium urate crystals in joints causing acute inflammatory episodes and tophi, not primary degenerative cartilage wear.

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.
