The video tutorial explores the integumentary system, focusing on the layers beneath the epidermis, primarily the dermis and the hypodermis. It highlights the differences between the avascular epidermis and the vascular dermis, which contains blood vessels, sensory receptors, hair follicles, and glands. The dermis is divided into the papillary and reticular layers, each with distinct connective tissues. The hypodermis, though not part of the integumentary system, is discussed for its protective and insulating functions.

What is the significance of dermal papillae in the papillary layer?

How does the hypodermis contribute to the integumentary system?

What types of connective tissue are found in the subcutaneous layer?
