Joshua Hall A&P Ch. 5 pt 1 = epithelial tissue

The study of tissues.

A group of cells and their products working together for a particular function.

Vertebrates are ____________ meaning that they come from three basic types of tissues

The three different cell types of an embryo that give rise to all tissues.

Tissue that covers things. Covers body surfaces, lines body cavities and ducts, form glands, and secrete products like hormones.

Epithelial tissue cells are tightly packed with very little extracellular space. All epithelial tissue cells have specialized cell to cell contacts. What are the three types of contacts/junctions?

Specialized cell to cell contact in epithelial tissues that stops things from passing through. Think of proteins that sew the cells together.

Specialized cell to cell contact in epithelial tissues that acts like a button and holds the cells together.

Specialized cell to cell contact in epithelial tissues that holds the cells together but also allows some materials to flow from cell to cell.

All epithelial tissues have a top/_____ surface and bottom/_____ surface. = All epithelial tissues exhibit polarity.

Term that means no blood supply.

Tissue that gives rise to digestive and respiratory tracts.

Tissue that gives rise to dermal bone, muscle, vertebrae, blood, and notochord.

Tissue that gives rise to nervous system, epidermis, and neural crest cells.

The point of attachment for basal tissue and connective tissue?

The basement membrane is connected to the connective tissue by what two lamina?

The lamina are non cellular!

What produces the basal lamina?

What produces the reticular lamina?

Epithelial tissues get their _________ from blood vessels in the connective tissue that is beneath them.

What arrangement of cells would you find in an area with not much wear and tear that also needs to perform lots of diffusion?

ex: lungs

What arrangement of cells would you find in an area with high wear and tear?

ex: tongue

Simple cell arrangements are useful for?

ex: lungs, digestive tract

Pseudostratified cell arrangements are useful for?

ex: trachea (coughs something up)

Stratified cell arrangements are useful for?

ex: skin, tongue

The removal of moisture from something.

When cells have died and hardened. This is good for preventing desiccation.

Stratified cuboidal cell arrangements are used for?

Cuboidal cells in general are usually used for this.

ex: ducts of large glands. sweat/saliva

Epithelial tissue with the main purpose of stretching.

ex: uterus, bladder, urethra

Where do most of our glands come from?

A cell, tissue, or organ that makes or secretes a product.

___________ glands produce hormones and secrete them into the bloodstream via exocytosis.

________ glands secrete products onto body surfaces or into body cavities.

Glands are usually made of _________ or columnar cells.

Endocrine glands secrete directly into the blood and are therefore ____________.

Exocrine glands have _______ that they secrete their products into. The products then move from their to the surface.

ex: sweat, mammary, saliva, sebaceous

Mucous glands and goblet cells are __________. They consist of only one cell and produce mucin that dissolves in water to create mucus. They secrete their products by exocytosis.

Type of gland that disperses its product when the whole membrane ruptures.

ex: sebaceous/pimple

Type of gland that disperses its product with budding vesicles.

ex: mammary gland milk lipids

Type of product that secretes its product by exocytosis as the product is produced.

ex: non fat mammary gland products
