Flashcards in Tissues 1 Deck (25):
1

What 5 things are we made of?

Cells
Extracellular Matrix
Tissue fluids
Tissue
Organs

2

What are the 4 tissue types?

Epithelia
Connective
Nerve
Muscle

3

What are the features of epithelia tissue?

Covers surfaces
Keeps cells connected
Separates compartments
Forms glands
Good adaptive powers
Good regenerative powers

4

Define a desmosome (adhering junction).

Stick cells together and help keep the structure of the epithelia intact.

5

Define a tight junction (occulting junction).

Seal intercellular spaces and are waterproof so no space for water or other solutes.

6

Define a gap junction (communication junction).

For cell to cell communication.

Look like tight junctions but have a rosette of proteins called connectents which allows ions to travel through the cell.

7

Where does the epithelial sit?

On the connective tissue basement membrane.

8

What does BL and RL stand for?

Basal lamina and reticular lamina.

9

What is cilia?

Finger like projection from apical surface. Movement of mucas.

10

Where is the apical surface?

Opposite the basal lamina.

11

What is the tubulin skeleton arrangement?

9+2 arrangement of tubulin doublets.

12

What is microvilli?

Increased surface area of cell, are smaller than cilia and thinner. Supported by microfilaments and used for absorption.

13

What are the 3 types of simple epithelia?

Simple squamous
Simple cuboidal
Simple columnar

14

What are the 3 types of stratified epithelia?

Stratified squamous
Stratified cuboidal
Stratified columnar

15

What is the odd type of epithelia?

Pseudostratified

16

What type of epithelia is the saliva gland made of?

Stratified columnar.

17

Where is transitional stratified epithelia found?

Urinary bladder and uretha.

18

Define hemidesmosomes.

Link one cell to the extracellular matrix.

19

Define glands.

Collections of secretory epithelial cells and can be single or multicellular.

20

What are the features of connective tissue?

Connects
Structure/function defined by extracellular matrix
Liquid to solid matrix

21

What defines the tissues?

Extracellular matrix proteins.

22

Name 3 things made from connective tissue.

Blood (filled with alubins)
Bone
Adipose (mainly fat)

23

What are the features of muscle tissues?

Cytoplasm is packed with contractile apparatus
Long, thin cells
Shorten lengths, close down spaces

24

What are muscle tissues stuffed with?

Myosin, actin and mitochondria.

25

What are the features of nervous tissue?

Communication
Nervous and support cells
Receives, generates and transmits electrical signals
Allows emotions
Integrates information
