Stratified Squamous Mucous (Locations)

Front 15

Function is protection and lubrication

Stratified Squamous Mucous (Functions)

Front 16

Keratinocytes

Back 16

produce keratin and a glycolipid-sterol that is emptied into the intracellular spaces and provides a water barrier to prevent the loss of body fluids

Front 17

Melanocytes

Back 17

Produce melanin pigment which gives skin its tone

Front 18

Langerhans Cells

Back 18

involved in the immune response, especially skin allergic reactions

Front 19

Merkel Cells

Back 19

slow adapting mechanoreceptors involved in cutaneous sensations

Front 20

single layer of cells that contain keratinocytes, melanocytes, Langerhans cells and merkel cells.

Back 20

Stratum Basale

Front 21

a. Columnar to cuboidal in shape and divide to provide continuous source of new epithelia cells.

Back 21

Stratum Basale

Front 22

The new cells from the stratum basale are pushed toward the surface making this layer

Back 22

Stratum Spinosum

Front 23

a. The round keratinocytes of the stratum spinsoum produce keratohyalin granules that begin to fill the cells and tonofilaments that bundle together to form tonofibrils.

Back 23

Stratum Spinosum

Front 24

The flattened cells from the stratum spinosum and accumulate large numbers of keratohyalin granules.

Back 24

Stratum Granulosum

Front 25

These cells fill with keratin, lose their nuclei and organelles, and they plasma membrane thickens.

Back 25

4. Stratum Lucidium

Front 26

Most superficial layer of skin, filled with keratin, have no nuclei or organnels and have a thick cell membrane

Back 26

5. Stratum Corneum

Front 27

a. A cell envelope covers the keratinized cells of the stratum corneum, providing a waterproof barrier

Back 27

Stratum Corneum

Front 28

1. Papillary Layer

Back 28

layer of loose connective tissue, which lies adjacent to the epidermis

Front 29

secrete an oily substance called sebum that protects the skin

Back 29

Sebacous Galnds

Front 30

secrete sweat and are important in body temperature regulation

Back 30

Eccrine Sweat Glands

Front 31

secrete pheromones

Back 31

Apocrine Sweat Glands

Front 32

tactile receptors that also sense low frequency vibrations and sensitive to light touch

Back 32

1. Meissner Corpuscles

Front 33

pressoreceptors that are important in tactile and vibration sensations and pressure.

Back 33

2. Pacinian Corpuscles

Front 34

tactile receptors that attach to collagen fibers and provide information on skin deformation

Back 34

Ruffini Endings
