Chapter 4

Question 1

What are tissues

Answer 1

groups of similar cells that have a common or related function

Question 2

What are the four primary tissue types

Answer 2

epithelial tissue, connective tissue, muscle tissue and nerve tissue

Question 3

what is histology

Answer 3

the study of tissues

Question 4

what is epithelial tissue

Answer 4

a sheet of closely adhered cells

Question 5

what are the man functions of epithelial tissue

Answer 5

protection, absorption, filtration, secretion sensory reception and excretion

Question 6

Polarity

Answer 6

means epithelial tissue has a top and bottom

Question 7

apical surface

Answer 7

top of the surface
the surface exposed to exterior enviroment or cavity
May be smooth or slick
May posses microvilli or cilia

Question 8

Basal surface

Answer 8

bottom of the surface
the surface that attaches to underlying tissue
acts as a adhesive sheet to anchor cell to deeper tissue

Question 9

specialized contacts

Answer 9

when epithelial tissue covers or lines its needs to fit closely together in order to act as a boundry

Question 10

regeneration

Answer 10

epithelial tissue has a high regenerative capacity
is stimiulated by loss of apical basal polarity and or broken lateral contacts

Question 11

glandular epithelium

Answer 11

makes up the structure of glands

Question 12

connective tissue

Answer 12

most abundant and widely disrubuted of primary tissues

Question 13

ground substance

Answer 13

unstructured material that fills up space between cells

Question 14

collagen

Answer 14

strongest most abundant connective tissue

Question 15

elastic fibers

Answer 15

long, thin fibers that allow for stretch and recoil

Question 16

reticular

Answer 16

forms delicate networks where connective tissue is closely located to another tissue type

Question 17

blast cells

Answer 17

immature cell that is mitocally active secretes ground substances and fibers

Question 18

cyte cells

Answer 18

mature cells that are less active and maintains extracellular matrix

Question 19

membranes

Answer 19

are composed of at least two primary tissue types

Question 20

cutaneous membrane

Answer 20

includes skin which is composed of epithelium anchored deeper connective tissue
exposed to air
thick, waterproof and dry

Question 21

mucous membrane

Answer 21

line passageways that have connections with the external enviroment

Question 22

serous membranes

Answer 22

asscoiated with cavities that are not open to the outside environment

Question 23

inflamation

Answer 23

injured cells release inflammatory chemicals which cause blood vessels to dilate and become leaky
clotting occurs

Question 24

what tissues regenerate well

Answer 24

epithelial tissues, bone, areolar connective tissue, dense irregular connective tissue, blood forming tissue

Question 25

what tissues have a moderate regenerating capacity

Answer 25

smooth muscle and dense regular connective tissue

Question 26

what types of tissues are not capable of regenerating

Answer 26

cardiac muscle and nervous tissue of brain a spinal cord

Question 27

where do tissues originate from

Answer 27

tissues arise from three primary germ layers known as the ectoderm, mesoderm and endoderm

Question 28

the epithelium of the esophagus is

Answer 28

lining and covering epithelium

Question 29

what type of cellular extention is located at the apical surface of the epithelium

Answer 29

cilia

Question 30

which tissue would heal the fastest after a injury

Answer 30

bone
