Apocrine Sweat (Suderiforus) Gland

*Pinches off which makes this a smelly gland

Arrector Pili Muscle

**Causes hair to stand up

Dermal Papilla Layer

**In the palms of the hands, soles of the feet

**They produce fingerprints which are known as epidermal ridges.

**Abundant capillary networks in the papillary layer furnish nutrients for the epidermal layers and allows heat to radiate to the skin surface.

**The pain and touch receptor "Meissner's Corpuscle" is in this layer

Hypodermis Layer

-Contains Adipose Tissue

Pacinian Corpuscle (pain receptor)

*Located in the Reticular Layer which is the deepest skin layer.  It is composed of dense irregular CT and contains many arteries and veins, sweat and sebaceous glands.

Reticular Layer

-This is the deepest skin layer.  It is composed of dense irregular connective tissue and contains many arteries and veins, sweat and sebaceous glands, and pressure receptors (Pacinian Corpuscles).  this layer is also layered heavily with collagenic and elastic fibers.  The abundant dermal blood supply allows the skin to play a role in the regulation of body temperature

Sebaceous (oil) Gland

-Sebaceous glands are found nearly all over the skin except for the palms of the hands, soles of the feet.  Their ducts empty into a hair follicle.

-this gland becomes active during puberty - this is a "Smelly"  Halocrine gland (release their product by the way of rupturing when the gland is full which means death to the cell)

-They secrete "SEBUM"

-Located within the reticular Layer

Stratum Basale (germinativum) Layer

-Contains Dermal Papilla and Reticular

-A single row of cells immediately adjacent to the dermis.  It's cells are constantly undergoing a mitotic division to produce millions of new cells daily.  10% to 25% of the cells in this stratum are melanocytes, which thread their processes through this and the adjacent layers of keratinocytes.  This is a nutrient rich layer

Stratum Corneum Layer (horney layer)

-This outermost epidermal layer consists of 20-30 cell layers and accounts for the bulk of the epidermal thickness.  Cells in this layer like those in the lucidum are dead and their flattened scalelike remnants are fully keratinized.  They are constantly rubbing off and being replaced by division of deeper cells

Stratum Granulosum (granular) Layer

-a thin layer named for the abundant granules its cells contain.  These granules are of two types (1) lamellated granules which contain waterproofing glycolipid that is secreted into the extracellular space and (2) keratohyaline granules, which combine with the intermediate filaments in the more superficial layers to form the keratin fibrils.  At the upper border of this layer, the cells are beginning to die.

Stratum Lucidum (clear) layer:

-Very thin translucent band of flattened dead keratinocytes with indistinct boundaries.  This layer is NOT present in thin skin.

Stratum Spinosum (Spiny Layer)

-A stratum consisting of several cell layers immediately superficial to the basal layer.  It's cells contain thick weblike bundles of intermediate filaments made of a pre-keratin protein.  The stratum spinosum cells appear spiky because as the skin tissue is prepared for histological exam, they shrink but their desmosomes hold tight.  Cells divide fairly rapidely in this layer, but less so than in the basale.  Cells in the basal and spiny layers are the only ones to receive adequate nourishment via diffusion of nutrients from the dermis.  So as their daughter cells are pushed upward and away from the source of nutrition, they gradually die.
