52
Q

People with albinism have a defect in tyrosinase, an oxidase that helps to control skin pigmentation production. In what epidermal layer is tyrosinase active.

A

Stratum Basale
1. Tyrosinase control male in production by melanocytes
2. Melanocytes are found in the deepest layer
3.

53
Q

What are features of the stratum granulosum

A
  1. Cells in the layer contain keratohyaline granules
  2. There are 3-5 layers of cells
  3. The cells in this layer secrete a lipid, waterproof layer
54
Q

Which structures contains connective tissue, blood vessels and nerves

A

Papillary and reticular dermis
1. A continuous basement membrane separate the epidermis from the dermis
2. Capillaries in the papillary dermis are responsible for perfusing the epidermis - O2 and nutrients diffuse across the basement membrane
3. Both dermal layers are comprised of connective tissue

55
Q

A

Reticular dermis
1. Arrector polo muscles attach to hair follicles to control individual hair movement
2. The hypodermis is an insulating layer, mostly comprised of fat deposits
3. The reticular dermis is the location or arrector pili muscles, anchored in the dense connective tissue

56
Q

A

Meissner’s
1. Pacinian corpuscles respond to deep touch
2. Arrector pili muscles control hair follicle movement
3. Meissners corpuscles respond to light touch and are found at the border of the epidermis and dermis - being damaged

57
