(a) Superficial fascia and cutaneous membrane

(b) Epidermis and subcutaneous layer

What widespread effects does epidermal growth factor (EGF) have on the integument?

The fibrous protein that is responsible for the strength and water resistance of the skin surface is

(b) Eleidin

(c) Keratin

(d) Elastin

(e) Keratohyalin

The cutaneous plexus and subpapillary plexus consist of

b. A network of nerves providing dermal sensations.

c. Specialized cells for cutaneous sensations.
