Protection, control permeability, sensation, secretion

Question 11

Cilia (epithelial)

Answer 11

Found in respiratory, moves material out of lungs, and reproductive, moves egg towards uterus

Microvilli

Answer 12

Increase surface area of cells that secret or absorb a lot

Question 13

Types of cell connections

Answer 13

• Demosomes: like a band of Velcro
• Hemidesomes: attaches epithelial to basement
• Gap junctions: channels of embedded proteins
• Tight junctions: found in top of membranes, in the space between cells can be blocked

Question 14

How does epithelia repair

Answer 14

Stem cells

Simple epithelium

Answer 15

A single layer of tissue

Question 16

Stratified epithelium

Answer 16

Multiple layers

Question 17

Simple squamous epithelium, and where is it found

Answer 17

One layer, things can diffuse through tissue.

Found in sacs of lungs, blood vessels, lymphatic

Question 18

Keratinized stratified squamous epithelium

Answer 18

For protection and found in places that are prone to friction or damage

Question 19

Non keratinized Stratified squamous epithelium and where is it found

Answer 19

For protection, lines vagina, mouth, esophagus

Question 20

Simple Cuboidal epithelia, where is it found

Answer 20

One layer of cuboidal cells, found in ducts that connect glands to surface

Question 21

Stratified cuboidal epithelium and where is it found

Answer 21

Two or more rows of cells and found in sweat glands and pharynx

Question 22

Where is transitional epithelium found

Answer 22

Lines organs subject to stress and that need to stretch i.e. Urethra and urinary bladder

Often 10 or more layers thick

Question 23

Simple columnar epithelia

Answer 23

Single columnar layer, found in stomach, large and sm intestine 
cells often modified per function 
Goblet cells (secretion)
Cilia (movement)
Microvilli (absorbtion)

Question 25

Stratified columnar epithelium

Answer 25

Very rare found in urethra and near anus

Question 26

Glandular epithelium

Answer 26

Specialized for secretion Exocrine glands- onto body surface like perspire on skin or saliva Endocrine glands- into blood or interstitial fluid

Question 27

3 classifications of exocrine glands

Answer 27

Merocrine Aprocrine Holocrine

Question 28

Define merocrine glands

Answer 28

Secrete through cell membrane (exocytosis) | Most numerous gland type

Question 29

Define apocrine glands

Answer 29

Uses part of cell for secretion, mammary glands

Question 30

Holocrine glands

Answer 30

Secretion products cause cell death, sebaceous glands

Question 31

Connective tissue characteristics

Answer 31

Most widespread and has extra cellular matrix made up of fibers, few cells and are vascular

Question 32

General functions of connective tissue

Answer 32

- connect muscles, bones - transport blood and lymphatic systems - protect delicate organs - support framework - storage of fat/energy

Question 33

3 types of connective tissue

Answer 33

- Connective tissue proper (fiberous) - Fluid connective tissues - Supporting connective tissues

Question 34

cells found in connective tissue proper

Answer 34

``` Fibroblasts Adipose Macrophages Mast cells Lymphocytes Melanocytes ```

Question 35

Connective tissue fibers

Answer 35

Collagen-strength Reticular-gives framework Elastic-allows stretch

Question 36

Loose connective tissue

Answer 36

Helps connect different tissues and acts like glue, stretchable Found around organs for protection

Question 37

Reticular tissue where is it found and function

Answer 37

Bone marrow, lymph nodes, spleen and mesh work filters things out

Question 38

3 types of Dense connective tissue

Answer 38

- Dense Regular fibrous connective tissue-fiber bundles parallel i.e. Knee ligament - dense irregular fibrous connective tissue-fibers intertwine like a mat i.e. Around Kidney - elastic tissue-elastic fibers-between vertebrae in spine
