Q

What is cartilage?

A

Only avasular C.T

20
Q

What are chondrocytes?

A

Cartilage cells that live in chamber spaces called lacunae

21
Q

What is perichondrium?

A

membrane that surrounds cartilage

22
Q

What is hyaline cartilage?

A

tough, somewhat flexible support, reduces friction between bones(ex: strenum & joints)

23
Q

What is elastic cartilage?

A

Supportive but bends easily(ex: ear)

24
Q

What is fibrocartilage?

A

Very durable & tough, limits movement, while resisting compression & prevents bone to bone contact(ex:knee joint)

25
Q

What is periosteum?

A

membrane that surrounds bone

26
Q

What is the osteon?

A

functional unit of compact bone

27
Q

What is the central canal?

A

center & contains blood vessels & nerves

28
Q

What is the lamellae?

A

layers of bone matrix around central canal while containing lacuna & ostrocytes

29
Q

What is canaliculi?

A

allows substance to diffuse between central canal & osteocytes(oxygen,carbon dixoide)

30
Q

What is the serous membrane (serosae)?

A

Lines body cavities that are not open to exterior of body, thin yet strong to reduce friction(ex:Thoracic & abdominal)

31
Q

What is the pleura?

A

covers lungs & lines pleura cavities

32
Q

What is the peritoneum?

A

Covers abdominal organs & lines peritoneal cavity

33
Q

What is the cutaneous membrane?

A

SKIN, that is thick & water resistant & dry

34
Q

What is the synovial membrane?

A

lines moving,articulating joint cavities, protects ends of long bones & releases synovial fluid for lubrication (ex: between hip-joint & knee)

35
Q

What is skeletal muscle?

A

Move the skeleton for body motion, cells are very strong,multinucleated, & striated. (voluntarity controlled)

36
Q

What is cardiac muscle?

A

Cells are branching,uninucleated, striated. Cells are connected & communicate at interclated discs(involuntary control)

37
Q

What is smooth muscle?

A

Found in walls of hollow,contracting organs,cells are small & spindle-shaped,unincucleated, non-striated (involuntary control)

38
Q

What are neurons?

A

Main functional cell that conducts signals

39
Q

What is the cell body?

A

contains nucleus & most other organelles

40
Q

What are dendrites?

A

Receives a signal (look like branches)

41
Q

What are axons?

A

Sends a signal (called action potential)

42
Q

What is the neuroglia?

A

supporting cells,repairs & supplies nutrients to neurons

43
Q

What can cause inflammation?

A

1.Trauma(physical injury)
2. Infection (presence of harmful pathogens)

44
Q

What are histamine,heparinm & prostaglandins?

A

The 3 factors that trigger inflammation

45
Q

What is regeneration?

A

When injury or infection is cleaned up regeneration begans.
