A

packaging material
thermal insulation
protecting organs

21
Q

Loose Adipose Location

A

subcutaneous areas
mammery glands
spaces and crevices

22
Q

Reticular Tissue (loose) Structure

A

Fine network of reticular fibers
irregular arrangement of cells and fibers
lymphocytes and leukocytes)

23
Q

Reticular Function

A

structure for lymphatic and hemopoietic tissues

24
Q

Reticular Location

A

lymph nodes
spleen
bone marrow

25
Dense Regular Tissue Structure
regularly arranged collagen and elastic fibers
26
Dense regular function
withstand pulling forces, tensile and resistance strength in direction of fiber orientation
27
dense regular location
vocal folds elastic ligaments
28
Dense Irregular structure
random array of collagen fibers
29
dense irregular function
tensile strength withstand stretching from all directions
30
dense irregular location
dermis organ capsules outer covering of tubes
31
Dense Elastic structure
bundles and sheets of collagenous and elastic fibers
32
dense elastic function
stretching capable of strength
33
dense elastic location
elastic arteries
34
Hyaline Cartilage structure
chondrocytes usually in groups collagen fibers are small and evenly dispersed
35
Hyaline cartilage function
allow growth of long bones rigidity with some flexibility
36
hyaline cartilage location
growing long bones cartilage rings of respitory tract costal cartilage embryonic skeleton
37
Fibrocartilage Structure
lots of collagen fibers in thick bundles less chondrocytes more spaced out
38
Fibrocartilage Function
some what flexible capable of withstanding great pressure connecting structures that have great pressure
39
Fibrocartilage Location
invertabral disks articular disks (knee and jaw)
40
Elastic Cartilage Structure
similar to hyaline but matrix has elastic fibers
41
Elastic Cartilage Function
provides rigidity with more flexibility than hyaline elastic fibers return to normal shape after being stretched
42
Elastic Cartilage Location
external ears epiglottis auditory tubes
43
Compact Bone Structure
compact circular oriented osteocytes enclosed in concentric circles in calcium salts
44
Compact Bone Functions
strength support forms solid outer barrier on bones
45
Compact bone Location
outer portion of all bones shafts of long bones
46
Blood Structure
fluid mix (only liquid tissue) blood cells( white blood cells and platelets)
47
Blood Function
gas, hormones, nutrient, waste transport protect against infection
48
Blood Location
within blood vessels
