(49 cards)
In what region of a long bone such as the humerus would you find the epiphyseal plate (growth plate)
Metaphysis
Which of the following tissues could be found on or within a bone such as the humorous
Adipose tissue
Nervous issue
Cartilage
Osseus tissue
Which two minerals are stored in major quantities in bone tissue
Calcium and phosphorus
What is the skeletal system composed of
Bones, curtilage joints ligaments
How many bones does the human skeleton consist of
206 bones grouped into two divisions
What are the divisions of the skeletal system
Axial skeleton and appendicular skeleton
How many bones does the axial skeleton consist of
80 bones
What are the three major regions of the axial skeleton
Skull, vertebral column, thoracic cage
How many cranial bones and how many facial bones
Eight cranial bones and 14 facial bones
What do the cranial bones do
I’m close the brain in the cranial cavity
What are sutural bones
They are small extra bone plates located within the suture of the cranial bones
What are sutures
They are jointed areas were flat bones come together
What are Fontanels
They are mesenchyme filled spaces between cranial bones present at birth. They close up beginning at six months her age through two years old
What are the eight cranial bones
Frontal bone Perietal bone Temporal bone Sphenoid bond Ethmoid bone
What does the HYO I D bone do
Supports the tongue by attaching to muscles
How many bones in the vertebral column
26 irregular bones and five major regions.
Cervical vertebra7
l, thoracic 12
, lumbar, 5
Sacrum, coccyx
What are the 3 types of Skelton cartilage
Hyaline
Elastic
Fibrocartilage
What is highlane cartilage
It provides support flexibility and resistance. It only has collagen fibers and it’s the most abundant type
What is elastic cartilage
Similar to highlane cartilage, but contains elastic fibers
What is fibrocartilage
The cartilage fibers, has great tensile strength
What is osteoprogenitor cells
They are located in the perichondrium and produce new layers of cartilage tissue from outside
What is interstitial growth
Chondrocytes increase the number of cells and the amount of matrix from within
What is the hyaline cartilage
It provides support, flexibility, and resilience. It only has collagen fibers and it is the most abundant
What is that osteon
The functional unit of a compact bone
