Tissues

Question 1

4 primary types

Answer 1

1. Epithelial
2. Connective
3. Muscle
4. Nervous

Question 2

Epithelial

Answer 2

Covers body surfaces for protection, line internal organs for absorption and excretion, and make up glands for secretion

Question 3

Basement membrane

Answer 3

Layer that anchors epithelial to connective tissue

Question 4

Shapes

Answer 4

Squamous, cuboidal, columnar

Question 5

Layers

Answer 5

Simple (single
Stratified (multiple)
Pseudostratified (appears to be multiple, but is really a single layer)

Question 6

Simple squamous

Answer 6

Single layer, flat thin cells,

Example- membranes

Question 7

Stratified squamous

Answer 7

Multiple layers of thin, flat cells

Example- skin, mouth, vagina, anus

Question 8

Simple cuboidal

Answer 8

Single layer, cube-shaped

Example- kidneys, ovaries

Question 9

Stratified cuboidal

Answer 9

Multiple layers of cube-shaped cells

Example- mammary glands, sweat glands

Question 10

Simple columnar

Answer 10

Single later of tall cells

Example- digestive tract

Question 11

Stratified columnar

Answer 11

Multiple layers of tall cells

Example- reproductive tract, male urethra

Question 12

Pseudostratified columnar

Answer 12

Ciliated, respiratory tract

Question 13

Transitional

Answer 13

Urinary bladder

Stratified but looks simple

Question 14

Connective tissue

Answer 14

Fibroblast- secretes protein fibers into matrix

Adipose- fat storage

Question 15

CT proper

Answer 15

Dense and loose

Question 16

Dense regular

Answer 16

Lots of collagen (strength)

Example- tendons, ligaments

Question 17

Dense irregular

Answer 17

Lots of collagen (strength)

Example- skin

Question 18

Loose, adipose

Answer 18

Fat storage (energy, cushion)

Example-abdomen, around heart,

Question 19

Loose areolar

Answer 19

Elastic fibers

Anchors skin packaging between muscles

Question 20

Elasticity

Answer 20

Rubber band ability to snap back together

Question 21

Loose, reticular

Answer 21

Reticular fivers, creates framework

Example- liver

Question 22

Supporting, cartilage, hyaline

Answer 22

Structural

Example- found on ends of bones, nose

Question 23

Cartilage

Answer 23

Elastic, flexible framework

Example- ears, epiglottis

MORE flexible than hyaline
