1. connect tissue and organs together
2. form basis of the skeleton

4. surround all the blood vessels and nerves of the body
5. Lead the body's fight against infection

Front 3

Function of Muscle Tissue

Back 3

Bring about most kinds of movement

Front 4

Functions of the Nervous tissue

Back 4

regulate and control body function

Front 5

Connective tissue classes

Back 5

Adipose
Areolar
Bone
Blood
Cartilage
Elastic
Fibrous

Front 6

Areolar

Back 6

fibroblasts and a matrix of tissue fluid, collagen, and elastin fibers –
subcutaneous where it connects skin to muscles and in mucous membranes of the digestive, respiratory, urinary, and reproductive tracts

Front 7

Elastic

Back 7

mostly elastin fibers (matrix) with few fibroblasts – walls of large arteries and around alveoli in lungs – helps maintain blood pressure and promotes normal exhalation

Front 8

Fibrous

Back 8

mostly collagen fibers (matrix) with few fibroblasts – tendons and regular ligaments and irregular dermis – provides strength to inner layer of skin and strength to withstand forces of joint movements

Front 9

Collagen fibers

Back 9

most common fibers, long, straight, and unbranched.

Front 10

Elastic fibers

Back 10

contain the protein elastin and are branched and wavy, returning to their original length after being stretched

Front 11

Reticular fibers

Back 11

least common of the three, thinner than collagen fibers, forming a branching, interwoven network in various organs.

Front 12

Fibroblasts

Back 12

most abundant cells responsible for the production and maintenance of the connective tissue fibers and the ground substance.

Front 13

Macrophages

Back 13

engulf (phagocytize) pathogens or damaged cells encountered in the tissue

Front 14

Adipose cells (adipocytes)

Back 14

A fat cell contains such a large droplet of lipid that the nucleus and other organelles are pushed to one side. The number of cells varies from one tissue type to another, from one region of the body to another, and from one individual to another.

Front 15

Mast cells

Back 15

mobile connective tissue cells often found near blood vessels. The cytoplasm is packed with vesicles filled with chemicals that are released to start the body's defence system when the need arises.

Front 16

Basal Lamina or basement membrane

Back 16

Supporting sheet, acts as a selective filter determining what molecules from capillaries in the underlying connective tissue are allowed to enter the epithelium, also helps with regeneration of epithelium

Front 17

Squamous

Back 17

smallest, flatest

Front 18

cuboidal

Back 18

medium, squar

Front 19

Columnar

Back 19

Column like, tallest

Front 20

Simple vs stratified

Back 20

one layer, multiple layers

Front 21

Simple Squamous epithelium

Back 21

lines blood vessels, air sacs of lungs- functions in absorption

Front 22

Simple columnar epithelium, with microvilli

Back 22

lines small intestine functions in absorption

Front 23

stratified squamous epithelium

Back 23

skin, lining of mouth and esophagus functions primarily as a protective layer

Front 24

pseudostratified, ciliated columnar epithelium

Back 24

lines nasal cavity and trachea functions in movement of substances along air passageway (a special type)

Front 25

transitional epithelium

Back 25

bladder, allows for distension/stretching of the bladdar (a special type)

Front 26

Exocrine glands

Back 26

external secretion
numerous
secretion onto body surfaces

Front 27

Endocrine glands

Back 27

Secretes hormones
internal secretion
ductless

Front 28

Goblet cell

Back 28

One celled exocrine glands
produces Mucin (which mixed with water makes mucus)

Front 29

Loose connective (areolar) tissue

Back 29

Gel like matrix, has fibroblasts, macrophages, mast cells, white blood cells

Front 30

Function of Loose connective (areolar) tissue

Back 30

wraps and cushions organs, it's macrophages phagocytize bacteria, plays a role in inflammation, holds and conveys tissue fluid

Front 31

Locations of Loose connective
(areolar) tissue

Back 31

widely distributed under epithelia of body

Front 32

Dense regular connective tissue

Back 32

primarily parallel collagen fibers, a few elastic fibers, major cell type is fibroblast

Front 33

Function of Dense regular connective tissue

Back 33

Attaches muscles to muscles or bones and bones to bones, withstands great tensile stress when pulling force is applied in one direction

Front 34

Location of Dense regular connective tissue

Back 34

Tendons, most ligaments, aponeuroses

Front 35

Elastic connective tissue

Back 35

contains high proportion of elastic fibers

Front 36

Function of elastic connective tissue

Back 36

allows recoil, maintains flow of blood through arteries, aids passive recoil of lungs following inspiration

Front 37

Location of Elastic connective tissue

Back 37

Walls of arteries, within ligaments associated with the vertebral column, within the walls of the bronchial tubes

Front 38

Adipose connective tissue

Back 38

matrix but very sparse, closely packed adipocytes or fat cells, have nucleus pushed to the side by large fat droplet

Front 39

Function Adipose connective tissue

Back 39

reserve food fuel, insulates, protects organs,

Front 40

Locations Adipose connective tissue

Back 40

under skin in the hypodermis, around kidneys and eye balls, within abdomen and breasts

Front 41

Hyaline Cartilage

Back 41

most extensive cartilage type in body, forms embryonic skeleton and covers the surfaces of synovial joins

Front 42

Fibrocartilage

Back 42

has an extracellular matrix that is formed of primarily collagen fibers and there is little ground substance (intervertebral discs)

Front 43

Elastic cartilage

Back 43

has an extracellular matrix containing a preponderance of elastic fibers (ears and nose)
