Chapter 6: Cartilage and Bones (Unit 2)

Fibrocartilage

Act as shock absorber and help the body resist compressive forces

Osteroblast Fibroblasts Osteoclasts

All are involved with fracture repair

Metaphysis

B) Contains the growth plate

Osseous Tissue

Bones primary component other wise known as bone connective tissue or____?

Outeroblast

Cells that produce new bone

Chondroblasts

Cells that produce the matrix of cartilage

Medullary Cavity

Contains bone marrow

Elastic cartilage

Contains numerous elastic fibers within the matrix; ensures resiliency and flexibility (Location external ear/ throat)

Endosteum

Covers all internal surface of the bone

Periosteum

Covers the outter surface bone

Fleshy, external part of the ear

Elastic Cartilage

Long Bones

Examples include tibia, phalanges, and humerus

Epiphysis

Expanded, knobby regions, help strengthen to joint by increasing the surface are for "bone to bone" contact

Articulating Surface

Facet, Head, Condyle, Epicondyle

Pubic symphysis

Fibrocartilage is located

Phalanges

Finger bones

Trabecular Bone

Found in Trusses and Arches

Interstitial growth

Growth in length

Appositional growth

Growth in thickness

Trachea

Hyaline cartilage is located

Hyaline cartilage

Is found joining the ribs to the sternum (Trachea)

Patella

Kneecap

Osteoclasts

Large cells , involved with the bone resorption process

Tibia

Leg bone

Calcium

Most important mineral throughout life to assist in maintaining strong bones

Attachments for ligaments and tendons

Rami, trochanters, tubercles, and tuberosities are bone marking that serve as ___?

Osteocytes

Reside within the lacunae, help maintain mechanical stress on a bone

Functions of Cartilage

Support soft tissue, Provides a protective covering at articulating surfaces, Serve as a model for bone growth

50 yrs old

The age calcium loss from bone be more than calcium deposits into bone, even with high calcium diet

Diaphysis

The shaft of the long bone

Osteoprogenitors

These cells help produce more stem cells that later mature to become osteoblasts

T

True or False Cartilage serves as a model for bone growth

Foramen

a rounded passageway through a bone is called

Humerus

bone of the arm

Trusses and Arches

help form internal scaffolding network

Lancunae

small spaces within the matrix

Hemopoiesis

the process of blood cell production
