Skeleto-muscular Flashcards
Substance that hardens their exoskeletal part
Chitin
Happens between the muscles and bone for more refined movements
Kinesiology
Skeleton is divided into two part

Classification of bone
Shape
-long bones
-short bones
-flat bones
-irregular
-round
Architecture
-spongy bone (cancellous bone)
-connect bone (lamellar body)
Fine structure
-primary bone (woven bone)
-secondary bone
Distal / ends of long bones
Epiphysis
Middle portion of long bones
Diaphysis
Outer layer of bone
Periosteum
Inner layer of bone
Endosteum
What can be found in the epiphysis ends
Compact bone
Articular cartilage
Spongy bone containing red marrow
What can be found in the diaphysis
Compact bone
Medullary cavity
this contains the yellow marrow (fat) lined with endosteum (squamous epithelium)
Medullary cavity
this contains the yellow marrow (fat) lined with endosteum (squamous epithelium)
Medullary cavity
Determines if bone has reached its maximum vertical growth
Epiphyseal line
Lines the medullary cavity
Endosteum
Very tough connective tissue that covers the inner surface of the bone
Endosteum
Is a very tough connective tissue that covers the inners surface of the bone and lines the medullary activity
endosteum
Protects the bone from foreign infections
Periosteum
Is made up of osteocytes housed by the lacunae
Compact bone
Arranged in concentric circles called lamallae
Compact bones
Surrounds a central canal / haversian canal; complex form is haversian system
Compact bone
It is made up of osteocytes housed by the lacunae and is arranged in lamellae. It also surround a central canal
Compact bone
It is the extension from the area of the epiphysis to the diaphysis
Trabeculae
It connects the haversian cannal
Volkmann’s canal
Area between haversian system
Interstitial lamellae
Three basic cells of bones
Osteoblast
Osteocytes
Osteoclast
These cells remove damaged cells and release calcium into the blood
Osteoclasts
These cells remove calcium from the blood and build new matrix. they then become trapped and eventually turn into osteoclasts
Osteoblasts
cranium and facial bones are found in the
Skull
Bones found the in skull
Cranium and facial boned
Bone responsible for anchoring tongues and muscles associated with swallowing
Hyoid bone
Bones in the vertebral column
Vertebrae and disks
Ribs and sternum are found in the
Thoracic cage
This bone anchors the tongue and muscles associated with swallowing

The lower limbs contains the
Legs
Group of bones located close to the axial skeleton
Girdle
Skeleton that supports and protects organs of head, neck, and trunk
Axial skeleton
Bones of limbs and bones that anchor them to the axial skeleton
Appendicular skeleton

1
This bone encases the brain, is an attachment for muscles and has sinuses
Cranium
Spaces inside the bone
Sinuses
