Q

The neuron consists of dendrites, a cell body, and a long axon; glia, or support cells, surround the neurons

Neurons transmit information in the form of action potentials, store “information,” and integrate and evaluate data; glia support, protect, and form specialized sheaths around axons

27
Q

Whether regeneration or fibrosis occurs depends on:

A
  1. Type of tissue damaged

2. Severity of the injury

28
Q
  • Capillaries become very permeable
  • Clotting proteins migrate into the area from the bloodstream
  • A clot walls off the injured area
A

Inflammation sets the stage

29
Q
  • Growth of new capillaries
  • Phagocytes dispose of blood clot and fibroblasts
  • Rebuild collagen fibers
A

Granulation tissue forms

30
Q
  • Scab detaches

* Whether scar is visible or invisible depends on severity of wound

A

Regeneration and fibrosis effect permanent repair

31
Q

Tissues that regenerate easily

E, F, B

A

Epithelial tissue

Fibrous connective tissues Bone

32
Q

Tissues that regenerate poorly

S

A

Skeletal muscle

33
Q

Tissues that are replaced largely with scar tissue

C, N

A

Cardiac muscle

Nervous tissue

34
Q

Connective tissue remains mitotic and forms ___

A

repair (scar) tissue

35
Q

Nervous tissue becomes ___ shortly after birth

A

amitotic

36
Q

tumor

both benign and cancerous, represent abnormal cell masses in which normal controls on cell division are not working

A

Neoplasms

37
Q

hypertrophy

increase in size of a tissue or organ may occur when tissue is strongly stimulated or irritated

A

Hyperplasia

38
Q

decrease in size of a tissue or organ occurs when the organ is no longer stimulated normally

A

Atrophy

39
Q
  • Thin sheet of tissue that covers a structure or line a cavity
  • Formed from a superficial epithelial tissue and connective tissue on which it rests
A

Tissue membrane

40
Q

4 classifications of Tissue Membrane

A

Skin
Mucous
Serous
Synovial

41
Q
  • Epithelial cells
  • Basement membrane
  • Lamina propria
  • Smooth muscles
A

Mucous

42
Q
  • Line cavities that do not open to the exterior and do not contain glans but do secret fluid
  • Mesothelium
A

Serous

43
Q
  • Formed by connective tissue
  • Line joint cavities (freely movable joints)
  • Secrete a lubricating fluid-synovial fluid
  • Injecting hyaluronic acid
A

Synovial

44
Q

Dry membrane

Outermost protection boundary

A

Cutaneous membrane

45
Q

is composed of keratinized stratified squamous epithelium

A

Epidermis

46
Q

is mostly dense (fibrous) connective tissue

A

Dermis

47
Q

Lines all the body cavities that open to the exterior body surface

Adapted from absorption or secretion

A

Mucous membrane

48
Q

Thick layer of loose connective tissue

A

Lamina Propria

49
Q

Line cavities that do not open to the exterior of the body

A

Serous membrane

50
Q

3 components Serous membrane

S, B, L

A

Mesothelium (SiSE)
Basement mebrane
Loose connective tissue

51
Q

Line freely moveable joints

Made up of only connective tissue

A

Synovial membrane

52
Q

Produce synovial fluid

A

Rich in hyaluronic acid making the joint very slippery thus facilitating smooth movement within the joint.

53
Q

involves a response that isolates injurious agents from the rest of the body and destroys the injurious agent

A

Inflammation

54
Q

Inflammation does not mean you have ___

A

infection

55
Q

Infection means you have __

A

inflammation

56
Q

5 symptoms of inflammation

A 
Redness
Heat
Swelling 
Pain
Disturbed function
57
Q

Redness also know as

A

erythema

58
Q

Heat also know as

A

calor

59
Q

Swelling also know as

A

edema

60
Q

Pain also know as

A

dolor

61
Q

Replacement of destroyed tissue by the same kind of cells

A

Regeneration

62
Q

cells cannot replicate. if killed, permanent tissue is repaired by replacement

cells example: neurons, heart cell, erythrocytes

A

Permanent

63
Q

cells do not ordinarily divide after growth is complete but can regenerate if necessary

cells example: liver, endocrine glands

A

Stable

64
Q

cells divide throughout life and can undergo regeneration

cells example: epidermis, epithelia of ducts, hepatocytes

A

Labile

65
Q

Repair by dense connective tissue

A

Fibrosis
