    Transcript

    00:01 So to wrap up our lecture on the integumentary system, recall that structures of integumentary system include the skin, hair and nails.

    00:12 There are two layers of skin including the epidermis and the dermis.

    00:17 The epidermis is a multi-layered avascular epithelium containing multiple cell types including keratinocyte, melanocytes, macrophages, and tactile cell.

    00:32 There are 4 to 5 layers of the epidermis.

    00:36 Starting with the outside, we have the stratum corneum, the stratum lucidum which is found in only the thick skin of the palms and the bottom of the feet, the stratum granulosum, the stratum spinosum and the stratum basale Deep to the epidermis we have the dermis.

    00:58 The dermis is a vascular connective tissue that is further divided into the papillary and reticular regions.

    01:08 The function of the skin include protection, thermoregulation, vitamin D synthesis, serving as a blood reservoir, excretion and absorption and cutaneous sensation.

    01:24 Finally, homeostatic imbalances of the integument include things like the formation of wounds, skin cancers and burns.

    01:34 This concludes our lecture on the integumentary system.

    01:38 Thank you for listening.
