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
