5 Functions Of The Skeletal System
- 1.Supports and gives shape to body
- 2.Protects internal organs
- 3.Helps make movement possible
- 4.Stores Calcium
- 5.Hemopriesis
-
3 Types Of Joints
- 1.Synarthroses-sutures of skull
- 2.Amphiarthroses-symphysis pubis
- 3.Diarthroses-ball and socket
-
Bone & Functions
- A.articulating Cartilage-cushions and protects joints from erosion
- B.spongy bone-houses the bone marrow
- C.epiphyseal plate-causes growth in length through mitosis
- D.red bone marrow-produces blood cells
- E.compact bone-gives strength to bone
- F.medullary cavity-houses the yellow bone marrow
- G.endosteum-lines the medulary cavity, causes growth in width
- H.yellow bone marrow-non-blood forming marrow
- I.periosteum-membrane that covers the bone, causes growth in width
- J.epiphysis-end of the bone
- K.diaphysis-shaft of the bone
-
Multiple Choice
- amphiarthroses-slightly movable joint
- appendicular skeleton-upper and lower extremities
- articular cartilage-covers epiphyses as cushion
- articulation-joint movement
- axial skeleton-skull, spine, thorax, and compact bone
- canaliculi-microscopic canals within the compact bone
- chondrocytes-cartilage cells
- compact bone-hard bone
- diaphysis-shaft portion of a bone
- diarthroses-free moving joint
- epiphyseal fracture-break in the end of the bone
- epiphyses-end of a bone
- Haversian system-network of vascular & nervous tissue
- hemoposiesis-blood cell formation
- kyphosis-arch back
- lacunae-space in hard bone full of osteocytes
- lamella-concentric rings of bone tissue
- lordosis-sway back
- medullary cavity-cavity of the diaphysis
- osteocytes-mature bone cell
- pectoral girdle-shoulder
- pelvic girdle-hip
- periosteum-membrane that covers bone
- red bone marrow-makes blood cells
- scoliosis-abnormal migration of the spine
- sinus-cavity
- trabeculae-bony portion of spongy bone
- thorax-chest region
- yellow bone marrow-inductive bone marrow of the diaphysis
-
Length
the esiphyseal plate makes growth in the bone with mitosis. The chondrocytes of the plate divide and become bone.
-
Width
stress on the periosteum causes the adjacent osteolasts to secrete astoid which causes new bone tissue to be formed on the exterior of the bone.
-
Fractures
- Complete-fracture extends all the way through the bone
- Incomplete-partially
- Compound-broken through skin
- Simple-broken not through skin
- Comminuted-splintered w/ small fragment
- Greenstick-one side broken, other side bent
- Impacted-one bone inside the other
-
