Connective Tissue Flashcards
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
What does connective tissue consist of?
Cells are similar in different connective tissue in matrix of ground substances & fibers
What ground substance in proper connective tissue? In cartilage?
Thin gel
Firm gel
Impregnated with inorganic salts in bone
What are fibers in connective tissue?
Collagen
Elastin
Properties of collagen?
Tough and resistant to force, fibers are parallel in fiber
Properties of elastin?
Strong and can be stretched, fiber branch
What are two types of connective tissue?
Proper: fascia, ligament, tendons
Specialized: cartilage and bone
Properties of proper connective tissue?
Tough but compliant
Properties of specialized connective tissue?
Solid Resist pull (tension) and pressure (compression)
What are two types of proper connective tissue?
Loose
Dense or fibrous
Does proper connective tissue support? What is it called when it contains lots of fat?
No
Adipose tissue
What is superficial fascia?
Layer immediately under skin where fat stored
What dominate in dense/fibrous proper connective tissue? What does it include?
Fibers
Deep fascia/ ligament/ tendons
What is fascia? Functions?
Sheets that envelop body parts
- Stores water and fat.
- protection against blow
- pathway for nerves and blood to enter and exit muscles
What does deep fascia blend with?what is medial and lateral fascia called?
Periosteum to connect to bone
Septa
What is internal fascia function?
Connect pleura(thorax) and peritoneum (abdomen) to body wall
What differentiates the tissues?
The matrix of ground substance and fibers
