(Packing materials) fills spaces between organs, cushion cells, and supports attached epthelia

Question 5

What is areolar C.T?

Answer 5

least specialized type of C.T. (found in deep layer of skin)

Question 6

What is Adipose C.T?

Answer 6

Contains many fat cells,shrink as fats released & expand to store fats

Question 7

What is white fat?

Answer 7

Most common type of fat, found in adults(absorbs shocks & slows heat loss)

Question 8

What is brown fat?

Answer 8

Found in infants & young children (It’s brown cuz more vascularized) When fat is broken down & released it’s used for body temp

Question 9

What is reticular C.T?

Answer 9

Complex 3-dimensional network,consist of fibers that support functional cells

Question 10

What is dense regular C.T?

Answer 10

Contains fibroblast & tightly packed collagen fibers in parellel to resist force in one direction(ex: makes damaged tendons & ligaments slow to heal)

Question 11

What is dense irregular C.T?

Answer 11

Networks of collagen & elastic fibers, Resist forces in different directions(Found in deep layer of skin)

Question 12

What is Elastic C.T?

Answer 12

amounts of elastic fibers(found in spinal vertebrae,and wall like the aorta)

Question 13

What is fasciae?

Answer 13

C.T. layers & wrapping that support & surround organs

Question 14

What is superficial fasciae?

Answer 14

separates skin from underlying tissue,allowing to move independently while providing padding(fat under skin)

Question 15

What is deep fasica?

Answer 15

middle layer,fibers in each layer are in different direction to add strength & form strong fibrous internal framework

Question 16

What are subserous fascia?

Answer 16

deepest layer, separates deep fascia from mesothelium of serous membrane that line body cavities

Question 17

What is interstital fluid?

Answer 17

Between cells, formed when blood pressure forces fluid out of capillaries

Question 18

What are platelets?

Answer 18

promote blood clotting

Question 19

What is cartilage?

Answer 19

Only avasular C.T

Question 20

What are chondrocytes?

Answer 20

Cartilage cells that live in chamber spaces called lacunae

Question 21

What is perichondrium?

Answer 21

membrane that surrounds cartilage

Question 22

What is hyaline cartilage?

Answer 22

tough, somewhat flexible support, reduces friction between bones(ex: strenum & joints)

Question 23

What is elastic cartilage?

Answer 23

Supportive but bends easily(ex: ear)

Question 24

What is fibrocartilage?

Answer 24

Very durable & tough, limits movement, while resisting compression & prevents bone to bone contact(ex:knee joint)

Question 25

What is periosteum?

Answer 25

membrane that surrounds bone

Question 26

What is the osteon?

Answer 26

functional unit of compact bone

Question 27

What is the central canal?

Answer 27

center & contains blood vessels & nerves

Question 28

What is the lamellae?

Answer 28

layers of bone matrix around central canal while containing lacuna & ostrocytes

Question 29

What is canaliculi?

Answer 29

allows substance to diffuse between central canal & osteocytes(oxygen,carbon dixoide)

Question 30

What is the serous membrane (serosae)?

Answer 30

Lines body cavities that are not open to exterior of body, thin yet strong to reduce friction(ex:Thoracic & abdominal)

Question 31

What is the pleura?

Answer 31

covers lungs & lines pleura cavities

Question 32

What is the peritoneum?

Answer 32

Covers abdominal organs & lines peritoneal cavity

Question 33

What is the cutaneous membrane?

Answer 33

SKIN, that is thick & water resistant & dry

Question 34

What is the synovial membrane?

Answer 34

lines moving,articulating joint cavities, protects ends of long bones & releases synovial fluid for lubrication (ex: between hip-joint & knee)

Question 35

What is skeletal muscle?

Answer 35

Move the skeleton for body motion, cells are very strong,multinucleated, & striated. (voluntarity controlled)

Question 36

What is cardiac muscle?

Answer 36

Cells are branching,uninucleated, striated. Cells are connected & communicate at interclated discs(involuntary control)

Question 37

What is smooth muscle?

Answer 37

Found in walls of hollow,contracting organs,cells are small & spindle-shaped,unincucleated, non-striated (involuntary control)

Question 38

What are neurons?

Answer 38

Main functional cell that conducts signals

Question 39

What is the cell body?

Answer 39

contains nucleus & most other organelles

Question 40

What are dendrites?

Answer 40

Receives a signal (look like branches)

Question 41

What are axons?

Answer 41

Sends a signal (called action potential)

Question 42

What is the neuroglia?

Answer 42

supporting cells,repairs & supplies nutrients to neurons

Question 43

What can cause inflammation?

Answer 43

1.Trauma(physical injury) 2. Infection (presence of harmful pathogens)

Question 44

What are histamine,heparinm & prostaglandins?

Answer 44

The 3 factors that trigger inflammation

Question 45

What is regeneration?

Answer 45

When injury or infection is cleaned up regeneration begans.
