1

Vitamin synthesized by skin cells needed in calcium metabolism and bone formation

Vitamin D

2

Embyological origin of epidermis

Ectoderm

3

Embryological origin of dermis

Mesoderm

4

Classification of subcutaenous tissue/hypodermis/subcutis

Loose CT

5

finger-like projections which anchor the epidermis to the dermis; responsible for finger printss

Rete ridges

6

Layer of the epidermis responsible for constant regeneration of other layers in the dermis; mitotic division

Stratum basale

7

Thickest epidermal layer where polyhedral keratinocytes are found; synthesizes keratin

Stratum spinosum

8

Layer of epidermis only found in thick skin

Stratum lucidum

9

Epidermal layer consisting of flat flakes and sheets of keratin; anuclear; touch protective layer in directcontact with outside environment

Stratum corneum

10

Clinical skin condition where there is abnormal increase in the number of proliferating cells in the basal layer; autoimmune disease tiggered by stresses

Psoriasis vulgaris

11

A depigmentation idsorder resulting from degeneration and disappearance of melanocytes

Vitiligo

12

Hereditary inability of the melanocytes to synthesize melanin; caused by absence of tyrosinase activity

Layer of the dermis that contains mast cells, wbcs, and macrophages; more ground substance and fibroblasts

Papillary layer of the dermis

14

Layer of dermis made of dense irregular connective tissue, contains blood vessels, nerve and skin appendages; stains more deeply; responsible for skin elasticity

Reticular layer
