Question

in _______, cells begin to flatten and develop lamellar granu begins, and nuclei and organelles begin to disintegrate
stratum basale
stratum spinosum
stratum granulosum
stratum lucidum
question 31 (1 point)
the _______layer of the dermis is connective tissue heavily inv vessels. the superficial surface has structures called _______
papillary; dermal papillae
papillary; reticular papillae
reticular; dermal papillae
reticular; reticular papillae

Explanation:

• Stratum Granulosum: In this layer of the epidermis, cells start to flatten, develop lamellar granules (which contribute to the skin's barrier function), and nuclei and organelles begin to disintegrate as part of the keratinization process.
• Papillary layer and dermal papillae: The papillary layer of the dermis is a connective - tissue layer rich in blood vessels. The superficial surface of the papillary layer has structures called dermal papillae. These dermal papillae increase the surface area of the dermis - epidermis junction, allowing for better exchange of nutrients and waste between the two layers and also contribute to the fingerprint pattern.

Answer:

• First question: Stratum Granulosum
• Second question: papillary; dermal papillae
