Tuesday 9/26 Tissues

Question 1

Simple squamous

Answer 1

Single layer of the egg shaped epithelial cells
Found lining blood vessels also in walls of alveoli (microscopic air sacs of lungs) also found cover many internal organs

Question 2

Simple cuboidal

Answer 2

Single layer of cube shaped epithelial cells
Found in walls of the kidney tubules( microscopic tubes that filter blood through urine)

Question 3

Simple columnar

Answer 3

Single layer of column shaped Epi cells
Lines the stomach, the intestines, and the fallopian tubes

Question 4

Stratified squamous

Answer 4

Multi layer of egg shaped epi cells
Outer layer of the skin ,lining of the nasal and oral cavity’s , pharynx, esophagus, vagina, urethra, anus

Question 5

Stratified, cuboidal and stratified columnar

Answer 5

Rare

Question 6

Pseudostratified columnar

Answer 6

Single layer of column shaped cells with a nuclei at different heights
Lines the trachea ( windpipe), bronchi(large airways), larynx(voice box), tubes of intestines

Question 7

Pseudostratified squamous and pseudostratified Cuboidal

Answer 7

No such thing

Question 8

Transitional Epithelium

Answer 8

Found lining urinary bladder and urethra
Multiple layers of epi cells the cells are squamous and cubodial shaped when the organs are stretched and column shaped when in stretched

Question 9

Connective tissue

Answer 9

Most abundant tissue in the body
Vascular (had blood vessels embedded) exceptions are cartilage and dense regular ct
Innervated( has nerves wired to it )
Has ability to regenerate (Heal itself to certain extent)
Made up of ct cells and ct matrix

Question 10

CT cells ending in “-blast”

Answer 10

Immature connective tissue cells
They are producing new connective tissue(healing or growing the tissues)

Question 11

CT cells end in “cyte”

Answer 11

Mature cells that are maintaining the matrix they are “-blast” cells that have become trapped in the be tissue they’ve made

Question 12

Osteoblasts/osteocytes

Answer 12

Bone cells

Question 13

Chrondroblasts/chrondrocytes

Answer 13

Cartilage cells

Question 14

Adipoblasts/Adipocytes

Answer 14

Fat cells

Question 15

Fibroblasts/Fibrocytes

Answer 15

Generic CT cells

Question 16

CT Matrix

Answer 16

The material surrounding ct cells
Give rise to the physical properties of the

Question 17

Ground substance

Answer 17

Fluid, gel, Or crystals surround the ct cells

Question 18

Connective tissue fibers

Answer 18

Proteins surrounding CT cells
3 types collagen, elastic, and reticular fibers

Question 19

Collagen fibers

Answer 19

Made up of collagen, protein molecules braided together
Resembles microscopic rope
Allows CT to bend/allows flexibility, but prevents stretch

Question 20

Elastic fibers

Answer 20

Like collagen fibers, but with a protein call elastin
Resembles microscopic bungee cords
Allows flexibility and stretch of a tissue
They recoil following stretch

Question 21

Reticular fibers

Answer 21

Interconnected web of collagen, protein molecules
Resembles microscopic fishing net
Allows the tissue to filter material flowing through it

Question 22

Areolar CT

Answer 22

Fibroblast/Phibro sites in a fluid matrix with all three fiber types
Found beneath epi tissues
It sticks/glued epi tissues to it organ
This will be found wherever you find connective tissue

Question 23

Adipose tissue

Answer 23

Adipoblast/cytes with very little matrix between cells a.k.a. fat tissue
Found in the bottom layer of skin “ hypodermis”

Question 24

Reticular CT

Answer 24

Fibroblast/cytes in a fluid matrix with reticular fibers
Found in spleen, bone marrow, lymph nodes

Question 25

Dense regular CT

Answer 25

Fibroblast/Cytes in a gel matrix with collagen fibers arranged in parallel
Found in tendons and ligaments

Question 26

Dense, irregular CT

Answer 26

Just like dense regular butt with the collagen, fibers, arranged randomly
Found in dermis (middle layer of skin )
Found in joint capsules

Question 27

Elastic connective tissue

Answer 27

Just like that’s a regular CT but with elastic fibers instead of collagen
Found in the lungs and arteries

Question 28

Hyaline cartilage

Answer 28

Chondroblast/Cytes in a gel matrix with collagen
Found in nose in on end of most bones

Question 29

Fibrocartilage

Answer 29

Just like hyaline cartilage, but with more collagen fibers
Tough/shock absorbing cartilage
Found in intervertebral disc menisci

Question 30

Elastic cartilage

Answer 30

Like hyaline cartilage, but with elastic fibers
Flexible cartilage
Found in ears

Question 31

Bone tissue

Answer 31

It is a connective tissue
A.k.a. Osseous tissue.
Osteoblasts/cytes and Crystal matrix with collagen fibers
Found in bones

Question 32

Blood

Answer 32

Blood cells in a liquid matrix
