Anatomy & physiology Chapter 5

Keratinized stratified squamous epithelial tissue is located

As the epidermis of the skin

A thin extracellular layer upon which an epithelium rests is called a

Basement membrane

Platelets

Blood Clotting

Nonkeratinized stratified squamous Location:

Body openings like the oral cavity,vagina, and anus

The type of connective tissue characterized by osteons with lacunae that is functionally used to support and protect other tissues in the body is ____ tissue

Bone

Example of a supporting connective tissue

Cartilage

Nonkeratinized stratified squamous epithelial tissue

Cells remain alive all the way to its apical surface, lines part of the anus, keratin not present within the cells, cells remain moist

Connective tissue, although diverse,share the following basic components;

Cells,protein fibers, ground substance

Serous membrane:

Contain parietal & visceral layer. Example: Pericardium

Nervous function:

Controls activities,processes information

Which statement describe the locations of epithelial tissue?

Covers body surfaces,lines many organs, cover many organs, lines body cavities

Epithelial function:

Covers surgaces and lines body cavities and organs

The ____ membrane is commonly called skin.

Cutaneous

The two categories of connective tissue proper are ___ connective tissue and _____ connective tissue

Dense,Loose

Keratinized stratified squamous Location:

Epidermis of skin

Four major tissue types

Epithelial,connective,muscle, and nervous

Muscle function:

Facilitates movement

How can epithelial tissues repair themselves:

Having high regenerative capacity

The study of tissues and their relationships within organs is called _______

Histology

Leukocytes

Immunity

Psudostratified ciliated columnar Location:

Lines upper respiratory tract

Transitional Location:

Lining of urinary bladder,ureters and part of the urethra

Where might you typically find simple squamous epithelium?

Lumen of blood vessels(Endothelium), Air sacs(alveoli) of lungs

An extracellular matrix is virtually nonexistent in which tissue types?

Nervous,muscle,epithelial

Simple squamous

One Layer of flat, wide irregular shaped cells

Simple columnar,nonciliated,

One Layer of tall,narrow cells that often contain microvilli

Simple Cuboidal

One layer of cells that are about as high as they are wide

Simple Columnar,ciliated

One layer of tall,narrow cells that can move objects along their apical surface

Functions of connective tissue

Physical protection, Storage and and transport, Binding and support of structures

Fibroblasts:

Produce fibers and ground substance

Connective tissue is designed to:

Protect,support, and bind organs.

Which type of epithelium is composed of a single layer of cells that are attached to a basement membrane but not all cells reach the apical surface of the epithelium?

Pseudostratified

Cutaneous membrane

Relatively dry compared to other membranes of the body, contains keratinized stratified squamous epithelial tissue

One cell layer thick epithelium

Simple

Epithelial cells are flat,wide, and somewhat irregular in shape

Squamous

Adipocytes:

Store lipid reserves

A ______ epithelium contains two or more layers of epithelial cells.

Stratified

Fixed macrophages:

These large cells phagocytize damaged cells and pathogens.

Which statements characterize serous membranes?

They contain a parietal and visceral layer. The pericardium is an example.

Erthrocytes

Transports O2 and CO2 between lungs and body tissues

Majority of glands are composed of epithelial tissue

True

True or false: tissues are groups of similar cells that carry out a common function.

True

True or false:Epithelium acts as "gatekeepers" to control the movement of substances into the body.

True

True or false: There are a larger number of glial cells than neurons

True. Neurons are much smaller in number than glial cells.

Functions of muscle tissue include

Voluntary movement of body parts, propulsion of materials through digestive tract,involuntary movement of body organs

Functions of muscle tissue include:

Voluntary movements of body parts, propulsion of materials through digestive tract, involuntary movements of body organs.

A _______ is formed when a sperm fertilizes and oocyte and forms a diploid cell

Zygote

The simple squamous epithelium that lines blood and lymphatic vessels is called

endothelium

Connective function:

protects, binds together and supports organs

Leukocytes are commonly called ____ blood cells.
