Q

3 Forms of Fibers within a matrix

A

Collagenous, Reticular, Elastic

24
Q

Collagenous

A

made of collagen proteins; most abundant protein in body

25
Q

Reticular

A

thin collagen fibers, often form sponge-like lattice

26
Q

Elastic

A

composed of elastin; capable of stretching & recoiling

27
Q

Areolar C.T

A

loose arrangement of collagenous and elastic fibers; found in blood vessels & nerves

28
Q

Reticular CT: structure & location

A

loose arrangement of reticular fibers and lymphocytes;

Found in lymph nodes, spleen, bone marrow

29
Q

Dense Regular CT

A

collagen & elastic fibers;
organized wavy-parallel pattern;
Found in ligaments and tendons

30
Q

Dense Irregular CT

A

collagen fibers not organized; found in Dermis of skin

31
Q

Adipose Tissue: Structure & Fxn

A 
closely-packed adipocytes; 
Store triglycerides providing: 
   - energy
   - insulation
   - cushioning
32
Q

Cartilage: structure, cellular composition, unique attribute

A

stiff, rubbery matrix;
composed of Chondrocytes;
only CT that is avascular

33
Q

Three Types of Cartilage

A

Hyaline, Elastic, Fibrocartilage

34
Q

Hyaline Cartilage

A

glassy-like appearance; fine collagen fibers found in trachea and larynx ; reduces friction

35
Q

Elastic Cartilage

A

composed of elastin & collagen fibers; found in external ear & throat

36
Q

Fibrocartilage

A

coarse collagen fibers; tough; found in vertebral discs, knee joints and pubis symphyses

37
Q

Bone Tissues: Cellular composition & Fxn (S.L.S.P)

A 
contains Osteocytes; 
Fxn in:
 - support
 - leverage for muscle movement
 - storage of minerals
 - protect internal organs
38
Q

Blood

A

liquid matrix surrounding formed elements; aids in protection & antibodies

39
Q

Formed Elements

A

RBCs, WBCs, Platelets

40
Q

Nervous Tissue

A

transmit electrical signals; contains neurons and neuroglia cells; found in brain, spinal cord, nerves

41
Q

Neurons

A

highly excitable transmit signals

42
Q

Neurogila Cells

A

supports neurons

43
Q

Muscle Tissue

A

causes movement, contains Myocytes; found in muscles (skeletal), heart (Cardiac), and internal organs (smooth)

44
Q

Myocytes

A

elongated and highly excitable; contract when excited leading to movements

45
Q

Name the 3 Types of Muscle Tissue

A

Skeletal, Cardiac, Smooth

46
Q

Glands

A

Cells or organs that secrete substances for secretion and excretion

47
Q

Exocrine Glands

A

tube-like ducts to secrete and excrete products; found in sweat glands and salivary glands

48
Q

Endocrine Glands

A

secrete hormones into bloodstream for transport

49
Q

Membrane: Describe and Name the 5 types (M.S.S.E.C)

A

flat sheet or layer made up of tissues; Mucous, Serous, Synovial, Endothelium, Cutaneous

50
Q

Mucous Membrane

A

lines passages that open to exterior of body; contains Goblet Cells; composed of epithelium, areolar and smooth muscle; Examples - digestive, respiratory, reproductive

51
Q

Serous Membrane

A

Simple squamous epithelial; produces serous (watery) fluid; found on organs and lines cavities

52
Q

Synovial Membrane

A

composed of connective tissue, associated with joints; secretes synovial fluid which helps protect and lubricate joints

53
Q

Endothelium

A

lines vessels of circulatory system; composed of simple squamous epithelial tissue and areolar CT; exchange nutrients and gases from blood

54
Q

Cutaneous Membrane

55
Q

Goblet cells

A

Produce mucus
