Term
Support
Definition
this is a function of the skeletal system that provides a framework for the soft tissues and also provides attachment points for the muscles.
Term
protection
Definition
this is a function of the skeletal system that surrounds the vital organs.
Term
Assistance in Movement
Definition
when the muscles contract around the skeletal system, they provide this:
Term
Mineral homeostasis
Definition
Bones store and release minerals and help maintain this in the blood:
Term
Blood Cell production
Definition
Red bone marrow does this:
Term
Triglyceride storage
Definition
this is a potential form of chemical energy in bones.
Term
Diaphysis
Definition
shaft of a bone
Term
Epiphyses
Definition
the very ends of a bone
Term
metaphyses
Definition
the area between the diaphysis and epiphyses
Term
articular cartilage
Definition
this is a thin layer of hyaline cartilage that covers the epiphyses
Term
periosteum
Definition
the outer covering on the bone
Term
sharpey's fibers
Definition
the periosteum of the bone is held in place by these:
Term
Medullary Cavity
Definition
the hollow inside a bone
Term
Endosteum
Definition
the layer that lines the medullary cavity
Term
Connective tissue
Definition
Bone is technically classified as what type of tissue?
Term
osseous tissue
Definition
bone can also be called this:
Term
water (15%), collagen fibers(30%), crystallized mineral salts(55%)
Definition
the extracellular matrix of a bone is made up of what?
Term
Calcium phosphate
Definition
this is the most abundant mineral salt in bone tissue
Term
hydroxyapatite
Definition
the product of combining calcium phosphate with calcium hydroxide forms crystals of:
Term
Calcification
Definition
this process is initiated by osteoblasts and deposits mineral salts in the framework of the collagen fibers.
Term
Collagen fibers
Definition
mineral salts begin to crystallize in the spaces between the:
Term
inorganic mineral salts
Definition
the bones hardness is dependant on:
Term
collagen fibers
Definition
a bone's flexibility depends on the:
Term
tensile strength
Definition
resistance to stretching or being torn apart describes what?
Term
osteoclasts
Definition
this cell secretes enzymes to break down the mineral salts between the collagen fibers:
Term
osteogenic cells
Definition
these are unspecialized stem cells for bone that are derived from the mesenchyme
Term
mesenchyme
Definition
this is the tissue where all connective tissue is formed from
Term
osteogenic cells
Definition
these cells are found within the inner periosteum and endosteum, and also the canals that house the blood vessels
Term
osteoblasts
Definition
these cells are bone builders
Term
osteocytes
Definition
these cells are mature bone cells
Term
osteocytes
Definition
these cells do not undergo cell division
Term
osteoclasts
Definition
these cells are a fusion of about 50 monocytes
Term
osteoclasts
Definition
these cells are concentrated in the endosteum of the bone tissue
Term
osteoclasts
Definition
these cells break down bone
Term
resorption
Definition
this term means the break down of bone under normal metabolic circumstances
Term
blood calcium levels
Definition
osteoclasts help to regulate this one very important metabolic function:
Term
compact bone
Definition
this type of tissue is the the strongest form of bone tissue
Term
periosteum
Definition
compact bone is found under this layer of bone
