Q

Epithelial Tissue

A

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

20
Q

Hemo

A

Blood

Very very vascular

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

21
Q

Areolar

A

Under layer of skin

22
Q

Adipose

A

Fat

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

23
Q

Regular

A

1 directions

Tendons/lymphoid

24
Q

Irregular

A

Wraparound bone, muscle fibers

25
Q

Hyaline

A

Toughest

End of bones, nose, connects ribs to sternum

26
Q

Fibro cartilage

A

Disco in knee, between vertebra

27
Q

Muscular

A

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

28
Q

Skeletal

A

Allows for movement of bones

Only works by contraction (shortening)

Voluntary

Striated

Lots of nuclei and mitochondria

29
Q

Voluntary

A

Consciously controlled

30
Q

Striated

A

Striped

31
Q

Cardiac

A

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

32
Q

Smooth

A

Visceral

  • involuntary
  • not striated
  • walls of stomach, intestines, bladder, blood vessels
  • can hold long and strong contraction
33
Q

Nervous

A

Neurons

Neuroglia

Must have O2

34
Q

Neurons

A

Major type of cell
(Motor, sensory, association)

Carry messages from one to another by electrical charge

35
Q

Neuroglia

A

Support system (glia)

Supply nutrients, pick up waste

36
Q

Membrane

A

Sheets of tissue that cover a surface

Epithelial
Connective

37
Q

Epithelial

A

Cutaneous
Mucous
Serous

38
Q

Cutaneous

A

Outside skin

39
Q

Mucous

A

Line body cavities that open to the outside of the body

40
Q

Serous

A

Line body cavities that don’t open to outside

* Pericardium 
* Pleural 
* Peritoneum
41
Q

Pericardium

A

Around your heart

  1. Viserural : touches/ surrounds heart
  2. Parietal : lining of wall
42
Q

Pleural

A

Around the lungs

  1. Viserural : touches/ surrounds lung
  2. Parietal : lining of wall
43
Q

Peritoneum

A

Digestive

  1. Viserural : touches/ surrounds stomach
  2. Parietal : lining of wall
44
Q

Connective Tissue

A

~Synovial fluid
~Periosteum
~Meninges
~Fascia

45
Q

Synovial fluid

A

Lines joint cavities to keep them lubricated and reduce friction

46
Q

Periosteum

A

Membrane surrounding your bones

47
Q

Meninges

A

Protections later around brain and spinal cord

48
Q

Fascia

A

Internal covering of the body
