Bone Cells
This cell makes up most of the bone
osteocytes
Why must bones be flexible and pliable as infants/babies?
What is flexion of bone and demonstrate it?
Reduction in the angle between two bones. Hinge joints example
What is the purpose of cartilage?
Reduces friction when moving bones against each other
increased porosity and decreased bone density. There are issues with the inorganic makeup of bones leading to increased risk for fracture.
these cells regenerate or form new bone (Baby cells)
osteoBlasts
Which type of marrow supports the creation of red and white blood cells?
Red Marrow
Demonstrate rotation of a bone and explain which bone goes over which bone:
Radius over ulna
Which ball and socket joint has the largest ROM in the human body?
Hip w/ femur
Osteo-malacia refers to:
these cells resorb bone and increase the amount of calcium in the bloodstream
osteoClasts
What is the function of yellow marrow?
Fat storage to supply energy for organism.
Define adduction and demonstrate an example
movement that brings bones toward the midline of the body
Why is osteosarcoma very dangerous?
It is cancer that leads to uncontrolled growth in the bones. It can damage bone integrity and metastasize to other parts of the body. Affects blood production due to red marrow issues.
a condition where the spine's integrity may be deformed, leading to an S-shape, when looking at the posterior side of the body.
What is the composition of bone (organic vs inorganic)?
65% inorganic
35% organic
Give two examples of long bones:
Femur, Humerus, many others...
Define abduction and demonstrate it
movement that takes a bone away from the midline of the body
Which is the joint type with the least mobility?
Synarthroses
Kyphosis refers to:
the bending of the superior spine (thoracics and cervicals), leading to a hunchback.
When are bones mostly composed of cartilagenous tissue rather than ossified bone?
during infancy
What are examples of irregular bones?
Vertebrae
How does arthritis affect motion?
The inflammation of the joints leads to reduced mobility due to increased friction or less space in the join
Which is the joint type with the most mobility and the joint type with a middle amount of mobility?
Diarthroses with most and Amphiarthroses with a middle amount
Lordosis refers to:
the bending of the spine at the lower spine (mostly lumbar region), leading to spinal instability.
