Integumentary system histology

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).
