chapter 3- tissues

Question 1

4 types of tissues

Answer 1

epithelial, connective, muscle, nervous

Question 2

the study of tissues

Answer 2

histology

Question 3

purpose of epithelial

Answer 3

protect everything in the body, secrete and absorb

Question 4

epithelial tissue is avascular, meaning

Answer 4

it has no direct blood flow, which keeps us from bleeding out when we get a scratch

Question 5

2 types of epithelial tissue

Answer 5

surface and glandular

Question 6

surface epithelial tissue function

Answer 6

lines things, vast majority

Question 7

glandular epithelial tissue function

Answer 7

secretes

Question 8

4 main classifications of epithelial tissue

Answer 8

simple squamous, stratified squamous, simple columnar, simple cuboidal

Question 9

single layer of flat cells that allow passage by diffusion

Answer 9

simple squamous

Question 10

thick membrane with multiple layers that are active in mitosis and present in lining all parts of body and protects from abrasion

Answer 10

stratified squamous

Question 11

single tall layer of cells present in digestive tract that have lots of surface area for absorption

Answer 11

simple columnar

Question 12

single layer of cube shaped cells in kidneys, small glands, etc that secrete

Answer 12

simple cuboidal

Question 13

4 types of connective tissue

Answer 13

connective tissue proper, cartilage, bone, blood

Question 14

most abundant and widely distributed tissues

Answer 14

connective

Question 15

3 types of mature connective tissue proper

Answer 15

collagen, reticular, elastic

Question 16

areolar

Answer 16

loose connective tissue proper, main function is to wrap and cushion organs, holds fluid and is site of inflammation

Question 17

adipose

Answer 17

loose connective tissue proper, reserves fuel and insulates

Question 18

reticular

Answer 18

loose connective tissue proper, network of fibers that are key in lymphatic organs, forms soft internal skeleton

Question 19

dense regular

Answer 19

parallel collagen fibers making up tendons and ligaments, withstands tension in a single direction

Question 20

muscles to bones

Answer 20

tendons

Question 21

bone to bone

Answer 21

ligament

Question 22

dense irregular

Answer 22

irregularly arranged fibers that withstand tension in many directions

Question 23

elastic

Answer 23

dense, regular elastic fibers that allow tissues to recoil (think lungs and heart)

Question 24

cartilage traits

Answer 24

gel like (80% water), avascular, if torn doesn’t recover, can withstand tension and compression

Question 25

hyaline cartilage location

Answer 25

every place bones are connected

Question 26

elastic cartilage locations

Answer 26

ears and epiglottis

Question 27

fibrocartilage locations

Answer 27

between vertebrae, meniscus, pubic symphesis

Question 28

bones are made of

Answer 28

calcium salts and collagen fibers

Question 29

2 parts of bone

Answer 29

spongy (internal) and compact

Question 30

3 blood cell types

Answer 30

erythrocytes, leukocytes, thrombocytes

Question 31

skeletal muscle

Answer 31

attached to bone- voluntary movement

Question 32

cardiac muscle

Answer 32

striated cells with intercalated disc- involuntary pumping of blood

Question 33

smooth muscle

Answer 33

spindle cells that form walls of hollow organs- propel substances along passageways

Question 34

nervous tissue

Answer 34

made of neurons with long cell processes, transmits electrical impulses
