|
|
Term
|
Definition
| cells of the stratum basale are attached to the basal lamina with these: |
|
|
Term
|
Definition
- epithelial cell of the skin that is the most numerous -arranged in five layers of stratum |
|
|
Term

Term
|
Definition
| function of this gland is not known |
|
|
Term
|
Definition
| -gland that secretes a moisturixing produce known as sebum |
|
|
Term
-free nerve endings -merkel cells -meissner's corpuscle -paccinian corpuscle |
|
Definition
| four types of nerves found in the skin |
|
|
Term
|
Definition
-layer of the skin classified as the stratified squamous keratinized epithelium -contains nerves and ducts of glands, but NO blood vessels |
|
|
Term
|
Definition
- not acutally part of the skin - loose connective tissue, fat |
|
|
Term
|
Definition
| - the most numerous epithelial cell of the epidermis, and are arranged in five layers. |
|
|
Term
|
Definition
-single layer of keratinocytes resting on the basal lamina - mitotic cells of the epidermis -source of regeneration in the cell |
|
|
Term
|
Definition
-essentially dead keratinocytes filled with keratin -layer that is shed from the surface of the epidermis -nuclei and organelles are degraded |
|
|
Term
|
Definition
| produce melanin pigment for skin coloration and protection against UV radiation |
|
|
Term
|
Definition
| -upon local infection of an area of the skin, these cells will take up and process microbial antigens |
|
|
Term
|
Definition
-associated with a nerve ending - believed to function as touch receptors or mechanoreceptors |
|
|
Term
|
Definition
| - Connective tissue layer of the skin |
|
|
Term
|
Definition
- sweat is produced by secretory cells and released on to the surface of the skin by a single duct -controls body temp |
|
|
Term
|
Definition
- glands in the armpit - secrete a mucin that empties on to the surface of skin through a duct associated witha hair follicle - bacteria metabolize the mucin and create an ordor |
|
|
Term
|
Definition
- secretory glands that secrete sebum that goes through a hair follicle out on to the surface of skin -sebum moisturizes hair and skin |
|
|
Term
|
Definition

|
Term
|
Definition
| - mechanoreceptors sencitive to light touch |
