Connective Tissue Flashcards
(40 cards)
What is ligament? Its properties?
Connect bone to bone
Composed of densely packed parallel collagen fibers
What is tendons? What is its property that differ from ligament?
Connect muscle to bone
Fiber more parallel than ligament
What connective tissue filled w/ synovoid fluid? What is it purpose?
Bursae
To reduce friction w bone, ligaments or tendons or subcutaneous (btw bone and skin)
What is aponeurosis?
Layered sheet like function as flattened tendon.
What cells cartilage contain? Does cartilage has blood supply and regenerate?
Chondrocytes
No
What types are there for cartilage?
Hyline
Fibrocartilage
Elastic cartilage
What is hyline cartilage function?
Cover articular surfaces of every bone to decrea fiction
Where are hyaline cartilage found?
At end of long bones, anterior ends of ribs, ring of trachea
What is the precursor to bone? Why?
Hyline cartilage. Because it ossifies but not everywhere
What cartilage acts as a shock absorber?
Fibrocartilage
Where are fibrocartilage founded? What are its properties?
Knee joint menisci
Invertebrae disks
It has small amount of blood supply
Firm collagen fibers
Where are Elastic cartilage founded? Is it collagen?
Outer Ear and distal nose
Larynx
Ligamentum flavum
No
What cells bone contain?
Osteocytes (no ground substance,all solidified)
How many bones skeletal have it?
206
What part of the bone is resilience?
What part of the bone is hard?
Matrix (collagen)
Mineral
What connective tissue encasing bone? What does it carry? What cells does it contain for repair?
Periosteum
Blood vessels, lymphatic and nerve fibers
Osteogenic Cells
What components bones have?
Cortex
Spongy/cancellous
What is the outer shell of bone called? Its properties? What arteries supply it?
Hard/dense
Supported and surrouded by periosteum
Periosteal arteries
What is the inner part of bone? What does it contain? What blood arteries supply it?
Spongy/cancellous
Bone marrow
Nutrient arteries
What are five functios o bone?
Protection
Support: vertebrae/framework
Mechanical:basis for movement providing attachment for muscle and levers for bones
Blood cell formation: in red bone marrow in the end of long bones
(Sternum/ribs, vertebrae/skull)
Mineral storage
What are two bones classification system?
Shape
Axial/appendicular
Example of long bone? Short? Flat? Irregular? Sesamoid
Finger, humerus Metacarples Parietal skull Vertebrae Knee cap (patella)
What are axial bones?
Sternum&ribs
Skull
Vertebral column
What do appendicular bones include?
Everything else
- pelvic girdle
- pectoral girdle
- upper/lower limbs
