Skin layers:

Remember layers as: "Cats Love Gooey Smelly Birds"

Stratum corneum:

• Anucleated, cornified/keratinized cells.

Stratum lucidum:

• Eosinophilic or anucleated cells; found in areas of thick corneum.

Stratum granulosum:

• Basophilic keratohyalin granules.

Stratum spinosum:

• Multilaminar cuboid-like cells.

Stratum basale:

• Contain keratin.

Cell Types:

Keratinocytes:

Provide barrier.

Melanocytes:

Melanin production.

Langerhans:

Immune.

Merkels:

Sensory.

Sweat Glands:

• Eccrine glands found everywhere; watery discharge; cholinergic innervation.

• Apocrine glands found in axillary, areolar and anal regions; thick, viscous discharge; adrenergic innervation.

Albinism:

Melanocytes are unable to synthesize melanin.

Vitiligo:

Melanocytes are destroyed.

Bullous pemphigoid:

Autoimmune blistering of dermis-epidermis junction.

Additional Notes:

• Keratin formation: stratum granulosum.

• Intercellular bridges: stratum spinosum.

• Papillae connect epidermis to dermis.

• Keratinocytes of epidermis derived from surface ectoderm.

• Dermis thickest at: upper portion of back.

• Hair grows from bulb.

• Abnormal keratin filaments: abnormal skin.

• Melanocytes present in matrix cells of hair follicles.

• Tight junction / zona occludens: glands; only columnar cells.

• Gap junction: heart, bones.

• Hemidesmosomes: basal lamina.

• Intermediate filaments / zona adherens: cells stick together (reinforcement).

• Desmosomes / macula adherens: bind cells together (main).
