Front 1

The function of Epithelial Tissue

Back 1

Protection, absorbtion, filteration, excretion, secretion, and sensory receptors.

Front 2

What is Apical - Basal Polarity

Back 2

Is related to epithelial tissues when they have both a basal and apical surface.

Front 3

What is the job of cilila

Back 3

Propel Substances

Front 4

Basal Lamina

Back 4

Sheet between the connective tissue and the epithelial tissues. it filers molecules coming from the connective tissue and is a site for Epithelial reapir.

Front 5

Lateral Contacts

Back 5

Except for glandualar: They are tight junctions and demosomes that bind cells at many point. Helps to keep apical cells from decending into the basal layer.

Front 6

Basement Membrane

Back 6

Just under the basal cell layer. made of Basal lamina and reticular lamina a connective tissue. Helps resist streching and tearing.

Front 7

Avascular but Innervated

Back 7

Avascular- No blood supply

Innervated- Supplied by nerve fibers

It is nurished by diffusion from the connective tissue underneath.

Front 8

What Causes Regeneration in Epitheleal.

Back 8

The apical- basal polarity and lateral contacts are destroyed. Epithelial cell reproduce rapidly

Are boxlike Cells

Front 12

Columnar

Back 12

Tall and skin (column like) cell type

Front 13

Simple Squamous Epithelial

Back 13

One layer and flat cells. Used in places of diffusion and filteration such as in the lungs

Front 14

Squamous

Back 14

Flat cell type

Front 15

Simple cubodial Epithelial

Back 15

One layer of cubelike cell. Used to secerte and absorb the in the kidney tubuals

Front 16

Simple columnar Epithelial

Back 16

One layer of colum like cells they absorb and secrete mucus in the digective track.

Front 17

Pseudostratifed Columnar Epithelial

Back 17

One layer of column like cells but is a "false' layer because the cells stop and end at random levels in the single layer. Has cillia on the surface and may have goblet cells. It secretes muscus and propels objects like in the trachea.

Front 18

Stratifed Squamous Epithelial

Back 18

Multiple layer os flat cells. Protects the body and gives it boundaries. Such as the layers of skin.

Front 19

Transitional Epithelial

Back 19

Several layers of cells. the apical surface are dome shaped and basal cells are cubodial or columnar. Allows for streching like for the urinary bladder.

Front 20

Glandualr Epithelial; EXOCRINE

Back 20

Unicellular, Secretes onto the skin surface or into body cavities. Muscus, sweat, oil and saliva. Also bile and enzymes.

Front 21

Glandular Epithelial; ENDOCRINE

Back 21

Multicellular, ductless glands because they eventually loos them. They produce hormones. They are strutually diverse, everyone is different.

Front 22

Structual Elements of connective tissue

Back 22

Ground substance: Plasma material

connective fibers:Collagen, elastic and reticular

connective cells: Mature (cytes) and inmatures (balst); Tissue is fibroblast, cartlidge is chondroblast and bone is osteoblast

Front 23

Fat cells

Back 23

Store nutrience

Front 24

White blood cells

Back 24

Tissue injury responds

Front 25

Mast Cells

Back 25

Detect Microrganisims them initiate an inflammatory responds.

Front 26

Macrophages

Back 26

Eat forgein material and dead tissue cells. Centeral actors for the immune system.

Front 27

Areloar: Loose Connective

Back 27

Contains elastic and collagen fiber, has fibroblast and groud substance. it wraps and cushions organs under the epithilium

Front 28

Adipose: loose connective

Back 28

Has sparse matrix. fat cells with small nuclei. Used to insulat the body.

Front 29

Reticular: loose connective

Back 29

Branching fibers in a gel substance and reticular cells. Used for interal structure of organs such as the spleen. (APPLE TREE)

Front 30

Dense Regualr

Back 30

Parallel collagen fibers and few elastic. major cell type are fibroblast. this attaches to muscle to bone. ligaments and tendons.

Front 31

Dense Irregular

Back 31

Randomly arrandged collagen fibers, fibroblast cell type. Found in joint capsules.

Front 32

Dense Elastic

Back 32

High majority of elastic fibers allows for recoil after streching like in walls of large arteries.

Front 33

Hyaline Cartlidge

Back 33

Firm matrix, collagen forms a network. Chondrocyte cell type. It supports and reinfores found at ends of long bones.

Front 34

Elastic cartlidge

Back 34

has elastic fibers in matrix, chondroblast cell type, strengths and reinforces found in the outer ear.

Front 35

Fibrocartlidge

Back 35

Thick collagen fibers. tensle stregth allows for compression shock like interverbal discs

Front 36

Osseus Tissue

Back 36

Bone tissue hard and calcified. contaisn many collagen fibers, osteocytes lie in lacunae rings. Protects and supports organs and muscles.

Front 37

Blood

Back 37

Red and white cells in fluid matrix. Transports respitory gases, nutriences and waste.

Front 38

Skeletal Muscle

Back 38

Long, cyndrial, multicellualr with obvisous stridations. Used for voluntray movement and attaches to bone.

Front 39

Cardiac Muscle

Back 39

Branching, striated, unicellualar intergrated at intercalcted discs (joints). Contratcs and propels blood in the circulatory systems.

Front 40

Smooth Muscle

Back 40

Spindle shaped cells with centeral nucleous. forms sheets. it propels objects thrugh a track such as the digective track.

Front 41

Nervous Tissue

Back 41

Branching cells called neurons. contains nonexcted supporting cells. transmits electrical signals to the brain.

Front 42

Cutanious Membranes

Back 42

Dry membranes

Front 43

Serous Membranes

Back 43

Wet membranes

Front 44

Tissue Repair Step 1

Back 44

1. inflammation

Loccal blood vessels become more permeable. clotting occurs on surface.

Front 45

Tissue Reapir Step 2

Back 45

2. Restores blood supply

Clot is replaced with granulation tissue. restores the vascular supply. collagen bridges the gap of the injury. macrophages devour dead tissue.

Front 46

Tissue Repair Step three

Back 46

3. Regeneration

Fibrosed area matures. epithelial thickens, fully regenerated skin with scar tissue underneath.
