BONE TISSUE AND THE SKELETAL SYSTEM(ch. 6) Flashcards
What part of the skeleton is this
Axial skeleton
Skull, thorax, and vertebral column
What part of the skeleton is this
Appendicular skeleton
-Limbs and girdles
-Leverage for movement
What is hematopoiesis
heh·ma·tuh·poy·ee·suhs
Production of blood cells
How many bones is in an adult skeleton
206
What are the 6 functions of the skeletal system
-Support
-Storge of minerals
-Blod cell production
-Protction
-Leverage
-Storage of adipose
What is adipose
yellow marrow used to provide energy reserve
Classification of Bones by Shape
Long bones are
-Long and slender
-deal with movement
Classification of Bones by Shape
Short bones are
-Small and box
-Stabilizers
Classification of Bones by Shape
Flat bones are
-Thin parallel surfaces
-Muscle attachment and organ protection
Classification of Bones by Shape
Wormain/Stutural bones are
-Irregular ones b/w cranial bones
-Varies among individuals
Classification of Bones by Shape
Sesamoid bones are
-Small and flat
-Form in tendons
-Protect tendons
Classification of Bones by Shape
Irregular bones are
-Complex shapes
-Most bones
Classification of Bones by Shape
Expamples of Long bones include/where are they most likely to be found
Upper limbs: huerus, radius, ulna, metacarpals, phalanges
Lower limbs: tibia, femur, metatarsals, phalanges
They are mostly found in the appendicular skelteton
Classification of Bones by Shape
Expamples of Short bones include/where are they most likely to be found
Upper: carpal
Lower: tarsal
Found in hands and feet
Classification of Bones by Shape
Expamples of Flat bones include/where are they most likely to be found
Upper: cranial, scapulae(sholder blades), sternum, ribs
Lower: pelvis
Found protecting import things
Classification of Bones by Shape
Expamples of Wormian/Sutural bones include/where are they most likely to be found
Found in the sutures of the skull can vary in nuber shape and size depending of the person
Classification of Bones by Shape
Expamples of Sesamoid bones include/where are they most likely to be found
Upper: 5 in each hand
Lower: 4 in each foot, patella(largest sesamoid bone)
Found in tendons
Classification of Bones by Shape
Expamples of irregular bones include/where are they most likely to be found
All over the body including the vertebrae
Long Bone Anatomy
What is the epiphysis line
* 4 pionts*
-Contains spongy (cancellous) bone
-red blood marrow for hematopoiesis
-compact bone covering
-articular cartilage(hyaline cartilage that cover joint ends to reduce friction)
Long Bone Anatomy
What is the diaphysis section
-made of walls of compact bone
-has the medullary cavity(hollow part of bone) thats lined by endsosteum filled with yelow bone marrow for adipose storage
3 pionts
Long Bone Anatomy
What is the metaphysis section
-area that contains the epiphyseal plate
Long Bone Anatomy
What is the periosteum layer
-attached to the bone by sharpey’s fibers(perforating plate)
-contains blood vessels/nerves
-site of tendon/ligament attachment
Long Bone Anatomy
Where is the epiphysis line
Its a line at the top of the bone
Long Bone Anatomy
Where is the diaphysis section
middle of bone (hollow section)
Long Bone Anatomy
Where is the metaphysis section
right under the epiphsis line
Long Bone Anatomy
Where is the periosteum layer
covers the outside of the bone
Long Bone Anatomy
What is the epiphyseal plate
a hyaline cartilage plate and the site from where the bone grows in length
Long Bone Anatomy
What is sharpeys fibers
bundles of collagen fiber which connect perioteum to bone
