1 of 27
What is the axial skeleton's function?
protection and structure
2 of 27
What is the appendicular skeleton's function?
movement
3 of 27
What is a long bone?
longer than wide, create levers for movement, produce red blood cells
4 of 27
What is a short bone?
Wider than long, absorb shock, weight bearing,
5 of 27
What is a flat bone?
wide and flat, protect vital organs, attach muscle, produce blood
6 of 27
What is an irregular bone?
allow for muscle attachment, irregular shaped, protection
7 of 27
What is a sesamoid bone?
Held together with tendons, prevents joint friction

How can I remember the order of my arm bones?
The humerus is where the funny bone is.
The ulna is under (inside)
The radius is radiating (outside/leaving)
14 of 27
How can I remember the order of my leg bones?
Femur extends like an 'f'
The patella is like patting your knee when laughing
The tibia is tucked inside
The fibula is for show outside
15 of 27
What is the vertebral column order?
Cervical, thoracic, lumbar, sarcal, coccygeal
16 of 27
How can I remember the vertebral column order?
Certain
Triumphs
Long
Shiny
Cups
17 of 27
What are the vertebral column's functions?
protect the spinal cord, movement, muscle attachment, attachment to ribs
18 of 27
What is neural spinal alignment?
Natural 's' curve shape with 3 natural curves
19 of 27
What is kyphosis?
Hunchback, excessive outward curve of thoracic region
20 of 27
What is scoliosis?
abnormal curvature to left or right, thoracic region, inheritable
21 of 27
give a brief summary of bone growth
ossification. calcium and phosphate accumulate on cartilage, trapped and cells die. tiny spaces left grow blood vessels to transport osteoblasts and nutrients.
22 of 27
what is ossification?
the process of bone growth and formation
23 of 27
what are osteoclasts?
cells that reabsorb part of the bone so unnecessary calcium is removed
24 of 27
what are osteoblasts?
cells that bring calcium to the body
25 of 27
what is a epiphyseal plate?
growing plates at the end of long bones
26 of 27
what is an epiphyseal line?
when the head of a bone fuses with the shaft
