large cells that produce the fibers and ground substance of fibrous connective tissue
fibroblasts
20
New cards
phagocytic cells that look for, engulf, and destroy bacteria and viruses in fibrous connect tissue
macrophages
21
New cards
Important part of immune system that monitors body for invasion and coordinates immune response in fibrous connective tissue
Leukocytes
22
New cards
found near blood vessels and produce factors that promote blood flow in inflamed tissues
Mast Cells
23
New cards
Collagenous fibers are made on
collagen
24
New cards
collagenous fibers found in
tendons and ligaments
25
New cards
reticular fibers are coated with
glycoproteins
26
New cards
reticular fibers are found in
some organs for structural support
27
New cards
Elastic tissue is found in
skin and lung tissue
28
New cards
Ground substance is made of
carbohydrates, proteoglycans, glycoproteins
29
New cards
many randomly oriented fibers (COLLAGEN AND ELASTIN). relatively few fibers, lots of ground substance
areolar
30
New cards
loosely arranged and tissue possesses many lymphocytes
reticular
31
New cards
Collagen fibers are densely packed and parallel to each other, very strong
Dense regular tissue
32
New cards
collagen fibers are densely packed but run in random directions. Allows tissue to absorb pressure and resist mechanical stress. Commonly found beneath skin and surrounding internal organs. Very little ground substance, very few visible cells, tightly packed collagen fibers are randomly arranged.
Dense irregular
33
New cards
Chondroblasts are found in
cartilage
34
New cards
cells of cartilage that secrete the matrix
chondroblasts
35
New cards
Cartilage Types
Hyaline, elastic, fibrocartilage
36
New cards
Hyaline cartilage is surrounded by
perichondrium
37
New cards
Hyaline cartilage is a precursor to
osseous tissue
38
New cards
All bones are covered by fibrous tissue called
Periosteum
39
New cards
Types of osseous tissue
spongy (cancellous), and compact
40
New cards
Bone cells are called
Osteocytes
41
New cards
Osteocytes live in
lacunae
42
New cards
Haversian canal is in ( ) and holds ( )
osseous tissue, blood vessels and nerves
43
New cards
Fluid connective tissue:
Blood
44
New cards
Blood connective tissue functions
transport materials, protective immune function
45
New cards
Leukocytes are in
blood
46
New cards
The non-cellular ground substance in blood is called
plasma
47
New cards
Formed elements of blood:
Erythrocytes, leukocytes, platelets
48
New cards
Cells of blood responsible for transport of O2 and CO2
