apocrine sweat glands
what gland produces sweat ear wax?
ceruminous
what is the most come type of cell in the epidermis?
keratinocytes
the tough, fibrous protein found in the epidermal cells is called….
keratin
which type of cell layer appears to have two or three layers of the cells, but are in contact with the basement membrane?
pseudostratified
3 types of cells found in the areolar connective tissue
- fibroblasts
- macrophages
3.Mast cells
connective tissue matrix is composed of
fibers and ground substances
in which quadrant of the abdominal-pelvic cavity is the stomach located ?
left upper quadrant
which organelle is responsible for synthesizing protein?
ribosomes
what are the purpose of Macrophages?
phagocytizes materials (bacteria and debris)
What does macrophages contribute to ?
to the body1s defense against injury and infection
Which Epithelial tissue: lining of the esophagus
Stratified squamous
Which Epithelial tissue: lining of the stomach
Simple columnar
Which Epithelial tissue: alveolar sacs of lungs
Simple squamous
Which Epithelial tissue: tubules of the kidney
Simple cuboidal
Which Epithelial tissue: epidermis of the skin
Stratified squamous
Which Epithelial tissue: lining of the bladder;peculiar cells that have the ability to slide over each other
Transitional
Which Epithelial tissue: forms the thin serous membranes, a single layer of flattened cells
Simple squamous
- Cells fit closely together
- Little intercellular material between cells
- The membrane has a free edge
Characteristics of epithelial tissue
A many layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as
Stratified squamous

Stratum corneum
Translucent cells in thick skin containing keratin fibrils
Stratum lucidum
Dermis later responsible for fingerprints
Papillary
Vascular region is which type of layer…
Dermis as a whole
Major skin area that produces derivates (nail and hair)
Epidermis as a whole
Epidermal region exhibiting the most rapid cell division
Stratum basale
Scale like dead cells , full off keratin
Stratum corneum
Mitotic cells filled with intermediate filaments
Stratum spinosum
Has abundant elastic and collagenic fibers
Dermis as a whole
Location of melanoctyes and merkel cells
Stratum basale
We like prekeratin filaments first appear
Stratum spinosum
Region of areolar connective tissue
Papillary
