Chapter 6 - Tissues & Membranes

Question 1

Histology

Answer 1

Study of tissues

Question 2

4 kinds of tissue

Answer 2

• Epithelial
• Connective
• Muscular
• Nervous

Question 3

Epithelial Tissue

Answer 3

Protects and transport

Continues sheets

Avascar ( no blood supply)

1 unattached surface and 1 attached

surface (to a basement membrane in order to get nutrients)

Lines cavities or organs

Easy regenerates and repairs

Layers
•simple; stratified; squamous; cuboidal; columnar; transitional; pseudo stratified

Question 4

Stratified

Answer 4

Multiple layers

Question 5

Simple

Answer 5

1 layer

Question 6

Squamous

Answer 6

Rapid diffusion, blood vessels

Question 7

Cuboidal

Answer 7

Transport & secrete (kidneys)

Question 8

Columnar

Answer 8

Absorption & digestion

Question 9

Transitional

Answer 9

Bladder

Question 10

Psendostatified

Answer 10

Look like multiple layers

Question 11

Connective (CT)

Answer 11

More than cells

Vascular varies

Fibers in matrix

Types of fibers
•collagen; elastic; reticular

Vascularity

  • loose, dense, cartilage, osseous, Hemo

Question 12

Collagen

Answer 12

Made of strong proteins

Question 13

Electric

Answer 13

Can stretch and return back to normal

Question 14

Reticular

Answer 14

Tiny collagen fibers that makes spider webs

Examples
• hollow organs
liver, spleen, lymph nodes

Question 15

Vascularity

Answer 15

Where there is more concentrated matrix

There is less room for blood vessels

Question 16

Loose

Answer 16

Very vascular

Heals quickly

Examples
• areolar
• adipose

Question 17

Dense

Answer 17

Less vascular

Heals slower

Example
• regular
• irregular
• elastic : bladder, stomach, lungs

Question 18

Cartilage

Answer 18

Non vascular

Fed diffusion

Examples
• Hyaline
• fibrocartilage
•elastic : ear, epiglottis, larynx

Question 19

Osseous

Answer 19

Bone

Very vascular

Small canals for blood vessels and nerves

Question 20

Hemo

Answer 20

Blood

Very very vascular

Examples
• matrix is called plasma
• stem cells in bone marrow

Question 21

Areolar

Answer 21

Under layer of skin

Question 22

Adipose

Answer 22

Fat

for energy 1lb of fat your body makes ~ 1mile of blood vessels

Question 23

Regular

Answer 23

1 directions

Tendons/lymphoid

Question 24

Irregular

Answer 24

Wraparound bone, muscle fibers

Question 25

Hyaline

Answer 25

Toughest End of bones, nose, connects ribs to sternum

Question 26

Fibro cartilage

Answer 26

Disco in knee, between vertebra

Question 27

Muscular

Answer 27

Composed of cells that contracted ~More cells then matrix ~Contractile proteins ~Very vascular - high demand for oxygen (O2) ~Close relationship with nervous system ~Cells chill in GO ~If muscled get really damaged you get scar tissue Skeletal Cardiac Smooth

Question 28

Skeletal

Answer 28

Allows for movement of bones Only works by contraction (shortening) Voluntary Striated Lots of nuclei and mitochondria

Question 29

Voluntary

Answer 29

Consciously controlled

Question 30

Striated

Answer 30

Striped

Question 31

Cardiac

Answer 31

Heart Self-contacting : has its own electrical system Involuntary Uses fatty acid tails for energy converts it the glucose to ATP Only 1 nucleus Striated • Junctions that keep muscles moving in sync

Question 32

Smooth

Answer 32

Visceral * involuntary * not striated * walls of stomach, intestines, bladder, blood vessels * can hold long and strong contraction

Question 33

Nervous

Answer 33

Neurons Neuroglia Must have O2

Question 34

Neurons

Answer 34

Major type of cell (Motor, sensory, association) Carry messages from one to another by electrical charge

Question 35

Neuroglia

Answer 35

Support system (glia) Supply nutrients, pick up waste

Question 36

Membrane

Answer 36

Sheets of tissue that cover a surface Epithelial Connective

Question 37

Epithelial

Answer 37

Cutaneous Mucous Serous

Question 38

Cutaneous

Answer 38

Outside skin

Question 39

Mucous

Answer 39

Line body cavities that open to the outside of the body

Question 40

Serous

Answer 40

Line body cavities that don’t open to outside * Pericardium * Pleural * Peritoneum

Question 41

Pericardium

Answer 41

Around your heart 1. Viserural : touches/ surrounds heart 2. Parietal : lining of wall

Question 42

Pleural

Answer 42

Around the lungs 1. Viserural : touches/ surrounds lung 2. Parietal : lining of wall

Question 43

Peritoneum

Answer 43

Digestive 1. Viserural : touches/ surrounds stomach 2. Parietal : lining of wall

Question 44

Connective Tissue

Answer 44

~Synovial fluid ~Periosteum ~Meninges ~Fascia

Question 45

Synovial fluid

Answer 45

Lines joint cavities to keep them lubricated and reduce friction

Question 46

Periosteum

Answer 46

Membrane surrounding your bones

Question 47

Meninges

Answer 47

Protections later around brain and spinal cord
