What is a tissue?

a group of similar cells that perform a particular function

Four primary tissue types found in the human body?

Epithelial, Connective, Muscle, Neural

Primary purpose of epithelial tissue

Provides protection, transport, sensation, and secretion

Basic characteristics that epithelial tissue share

covers all body surfaces, always has a "free" side, no blood vessels, and reproduce rapidly/heal quickly

Three basic epithelial cell shapes

squamous, cuboidal, columnar

Describe and name the two types of layering

Simple, simple layer of cells covering the basement membrane


Stratified, several layer of cells covering the basement membrane

Where in the body would simple epithelum be found and why

Inside of cornea, so light can pass through

How about stratified epithelium?

Skin, for protection and to withstand stress

What type of epithelium lines the air sacs of the lungs? Why?

simple squamous, allows oxygen to go through cells.

What are microvilli for? how about cilia

Microvilli increase surface area for absorption and cilia help move materials (sex cells, mucus)

Why is pseudostatified epithelium thus named?

Looks like it is layered but all cells contact basement membrane

What are the three basic components of all types of connective tissue?

Specialized cells, protein fibers(collagen and elastin), and fluid

What are the basic characteristics that connective tissue share

makes up membrane in the body, not tightly packed, and never exposed to the outside enviroment

What are the various functions of connective tissues?

Support, protection, transport, storage, and defense

Difference between tendon and ligament

Tendons connect muscle to bone and ligaments connect bone to bone

What type of connective tissue are tendons and ligaments

Fibrous connective or dense connective tissue

What are fibroblasts, macrophages, and mast cells

Fibroblast make collagen and elastin, macrophages clean out unwanted particles, and mast cells respond to injury/infection

What is collagen? what is elastin?

Collagen are white fibers and elastin are yellow fibers

What are chondrocytes and osteocytes

Chondrocytes are cartilage cells and osteocytes are bone cells

What is the major factor that influences how fast a connective tissue heals?

blood supply

What are the three types of cartilage in the body?

Hyaline, elastin, and fibro

Which type makes up the external ear? the pads between vertabre

elastin and fibro

Which cell is most abundant in blood

red blood cell

What are the three types of muscle tissue found in the body? Where are they found?

Skeletal-attached to bone,


smooth-organs, urinary tract, and blood vessels


Cardiac- found in heart

What muscle tissue is voluntary?

skeletal

What muscle tissue has striations

Skeletal and cardiac

What muscle tissue has intercalated disks

Cardiac

Number of Nuclei in skeletal? how about smooth and cardiac?

Skeletal has multiple nuclei and smooth and cardiac both have only one

What two fibers make up muscle tissue

collagen and elastin

What is neural tissue for

Collect stimuli, transmit impulses, and coordinate responses

In what order does the impulse pass through the neurons?

dendrites, cell body, axon, and end brush

What are the four signs of inflammation? What causes this?

Swelling, redness, heat, and pain. Caused by impact, abrasion, chemicals, pathogens, or extreme temperatures

How do tissues change as they age? what causes these changes?

Tissues repair more slowly and there is a thinning of cells
