2 Characteristic in Connective Tissues
|
Widely separated
Lots of Extracellular matrix Connects & Supports |
Is it close to each other?
surrounding fluid? Function |
|
|
Describe matrix
Significance? |
Nonliving
Ground Substance (proteins + fluids) Protein Fibers Matrix determines characteristic of tissue. |
|
|
|
Function of:
Chondroblast Chondrocyte |
Stem cell forms cartilage cell
Cartilage mature cell |
|
|
|
Functions of connective tissues
|
1. encloses, separates
2. supports, movement 3. storing, cushion 4. transport, protection |
|
|
|
Collagenous tissue:
Structure Function Location Vascularized? |
1. fibroblast (mature cell produces matrix filled w/ collagenous fibers)
2. tensile strength & resistance 3. tendons & ligaments 4. poor blood supply |
|
|
|
Cartilage:
Structure Function Location Vascularized? |
1. cartilage cell in lacuna, matrix has collagenous fibers
2. firm, flexible, resilient 3. 4. no blood supply |
|
|
|
Bone:
Structure Function Location Vascularized? |
1. osteocyte, in lacuna - matrix has Calcium phosphate & collagen
2. hard / rigid/resiliency 3. all over body 4. well vascularized. |
|
|
|
Organs of skeletal system & functions
|
1. bones - articulations - tendons & ligaments (BtoB)
2. support, protection, movement, blood cell production, storage (fat + Calcium) |
|
|
|
List of Long bones
Short bones Flat bones Irregular |
1. appendages, levers
2. blocky, wrist ankle bones 3. skull bones, sternum, ribs 4. facial bones, vertebrae |
|
|
|
axial skeletons
appendicular skeleton |
1. skull, ribs, sternum, thoracic cavity
2. limbs |
|
|
|
Compact bone:
location + function |
forms outer shell of bone
dense & strong |
|
|
|
Cancellous bone:
location + function |
boney rods & plates inner region of bone - inside compact bone
|
|
|
|
2 layers of periosteum + function
|
1. outer layer: dense irregular connective tissue
2. inner layer: osteoblast & osteoclast contains nerve fibers, blood, lymph vessels. |
|
|
|
location + function of Endosteum
|
membrane covering inside bone
single layer of osteoblast & osteoclasts |
|
|
|
Compact: Haversian system
|
1. made up of osteon
2. lamellae 3. osteocytes in lacunae 4. connected by processes called canaliculi 5. contains blood vessels & nerve 6. nutrients diffuse to osteocyte by canaliculi 7. hard, strong, resists |
