Answer

1) Cutaneous receptor: These are sensory nerve endings in the skin that detect various stimuli like touch, pressure, and temperature. 2) Stratum granulosum: This epidermal layer contains granules filled with keratin subunits or glycolipids (fatty material) for waterproofing. 3) Epidermis: The entire epidermal layer lacks blood vessels and relies on diffusion from the dermis below. 4) Papillary layer: This is the upper, more superficial region of the dermis, characterized by dermal papillae. 5) Stratum corneum and Stratum lucidum: These outer layers of the epidermis consist entirely of dead, keratinized cells. 6) Hair follicle: This is the complex structure that surrounds and produces the hair root. 7) Sebaceous gland: Acne occurs when these oil-producing glands become clogged and infected with bacteria. 8) Dermis: While hair and nails originate in the epidermis, their roots and structures like follicles are primarily embedded within the dermis. 9) Stratum Basale: This is the deepest epidermal layer where continuous cell division (mitosis) occurs to replace skin cells. 10) Sweat gland- Eccrine: These are the most common sweat glands, ubiquitous over the body, primarily responsible for temperature regulation. 11) Stratum corneum: This is the outermost layer of the skin, acting as a protective barrier. 12) Reticular layer: This deeper layer of the dermis contains a dense network of collagen and elastic fibers provided strength and resiliency. 13) Sweat gland- Apocrine: Found in specific areas like the axilla, these glands produce a thicker sweat containing proteins and fatty substances.
