what type of skin is represented by this slide
single layer of germinal cells resting on the basement membrane which is attached to the dermis
keratinocytes attached to each other by desmosomes on spiny processes
highly refractive zone only seen in very thick skin.
keratinocytes with numerous basophilic granules in their cytoplasm
thick layer of dead cells devoid of nuclei and organelle
What are the 3 types of nonkeratinocytes found in the epidermis?
Melanocytes
Merkel cells
These cells are located in the spinous layer of the epidermis and are known as antigen presenting cells
Melanocytes produce melanins which are packed into ___ and transported to the tips of dendritic processes
Keratinocytes in the spinous layer are interconnected by extensive ___
Which layer of the epidermis is absent in the mucous membrane of the mouth?
connective tissue firmly attached to the epidermis by the basement membrane
less organized connective tissue that supports the papillary and the epidermis
This isn’t technically a layer of the skin, but helps anchor the dermis to muscle or bone; loose CT that contains small to large adipose depots called Panniculus adiposus
Regarding hair, this part is the part above the skin surface
Regarding hair, this part is the part below the skin surface
The hair root is ensheathed in the ___
The hair follicle is the site of __ and is located in the __
produce a lipid rich secretion called sebum that is released into the hair follicle. Large cells with a central nucleus and a foamy appearing cytoplasm
coiled, tubular sweat-producing glands and ducts with simple or stratified cuboidal epithelium.
small muscles attached to hair follicles that cause hair to stand on end.
extends from the hair bulb to the level of sebaceous glands. It is divided into Huxley's layer (inner layer of flattened cells) and Henle's layer (outer single layer of cuboidal cells).
layers of cells continuous with the epidermis In a hair follicle
thick basement membrane that separates the hair follicle from the dermis
nerve endings in skin responsible for sensitivity to vibration and pressure.
nerve endings in skin responsible for sensitivity to light touch.
Located in dermal papillae.
Continuation of lactiferous sinus; lining epithelium is bi-layer stratified cuboidal to columnar
Teat sinus empties into here; opens to teat surface; lining epithelium is stratified squamous
in mammary glands, ___ are clustered to form lobules
___ cells surround alveolar epithelial cells contract for discharge of milk
Milk proteins released by ___ (think modes of secretion)
Milk lipids released by ___ (think modes of secretion)
