collection of specialized cells and cell products which perform a limited number of functions

4 types

Back 1

tissue

Front 2

study of tissue

Back 2

histology

Front 3

what are the 4 types of tissue?

Back 3

1. epithelial
2. connective
3. muscle
4. neural

Front 4

this tissue includes epithelia and glands

Back 4

epithelial tissue

Front 5

layer of cells that cover exposed surface or lines internal cavity

- composed of closely bound cells by cell junctions
-has an exposed surface and a surface attached to underlying tissue
- attached to basement membrane
- does not contain blood vessels
- continually replaced

Back 5

epithelium

Front 6

the exposed surface of the epithelium

Back 6

apical surface

Front 7

the side of epithelium attached to underlying tissue

Back 7

basal surface

Front 8

term for " does not contain blood vessels"

Back 8

avascular

Front 9

what are the 4 functions of the epithelium?

Back 9

1. provide protection
2. control permeability
3. provides sensations (detects changes in the environment and sends information to nervous system)
4. produces specialized secretions- glandular cells

Front 10

long microvilli

Back 10

sterocilia

Front 11

what are the 3 specialized functions of epithelium

Back 11

1. production of secretions by organelles
2. exposed surface of cell
3. movement of fluids over surface

Front 12

the epithelium actually attached to this

Back 12

basal laminae

Front 13

this gives strength to epithelium

Back 13

reticular laminae

Front 14

what does maintenance and repair of the epithelium depend on?

Back 14

stem or germ cells present

Front 15

what are the 2 types of epithelium?

Back 15

1. simple
2. stratified

Front 16

this kind of epithelium has one layer

Back 16

simple

Front 17

this kind of epithelium has several layers above basement membrane

Back 17

stratified

Front 18

this type of epithelia is...

- cells thin, flat, and irregular in shape
- in alveoli of lungs
-serous lining of body cavities and on surface of organs - mesothelium
- lines inner surface of vessels- endothelium

Back 18

simple squamos

Front 19

this type of epithelium is on surface where there is stress...

keratinized vs. nonkeratinized

- surface of skin
-oral cavity, pharynx, and esophagus
- rectur and anus
- vagina

Back 19

stratified squamous

Front 20

this type of epithelium appear square in shape.

Back 20

cuboidal epithelia

Front 21

this kind of epithelium occurs in regions of secretion and absorption
- kidney tubules
-pancreas: secretion
-salivary glands
- thyroid glands
-lines ducts of salivary glands

Back 21

simple cuboidal

Front 22

this kind of epithelium is rare
- in ducts of sweat glands
- large ducts of exocrine glands
- mammary glands

Back 22

stratified cuboidal

Front 23

this kind of epithelium permits stretching
-renal pelvis
- ureter
-urinary bladder

Back 23

transitional

Front 24

this kind of epithelium has a height greather than width

Back 24

columnar epithelia

Front 25

this kind of epithelium lines stomach and intestinal tract
-lines uterus
- excretory ducts
- gall bladder

Back 25

simple columnar

Front 26

this kind of epithelius is rare and is located in
- pharynx
-urethra
-anus
-excretory ducts

Back 26

stratified columnar

Front 27

this kind of epithelium is found in respiratory epithelium
- has cilia
-in nasal cavity
-trachea
-bronchi
- parts of male reproduction tract
- all cells in contact with basal membrane but do not all reach the surface

Back 27

pseudostratified columnar

Front 28

this type of glandular epithelium secretes onto the epithelial surface through ducts

Back 28

exocrine system

Front 29

this glandular epithelium secretes watery solutions

Back 29

serous

Front 30

this glandular epithelium secretes mucus

Back 30

mucous

Front 31

this glandular epithelium contains both mucous and serous elements

Back 31

mixed

Front 32

this structure of the exocrine gland is scattered in trachea, small and large intestines

Back 32

unicellular glands-- goblet cells-- mucus

Front 33

this structure of exocrine glands is located in the stomach as secretory sheet

Back 33

multicellular exocrine gland

Front 34

what are the 2 epithelial parts of multicellular exocrine glands?

Back 34

secretory part and duct part

Front 35

how are the multicellular exocrine glands organized?

Back 35

1. tubular
2. alveolar- acinar
3. tuboloalveolar

Front 36

what are the 2 ways ducts are organized?

Back 36

1. simple (no branching)
2. compound (numerous branching)
