What the Cell?
This cell lays down an extracellular matrix for creates new cartilage
What is a Chondroblast?
This is process by which new cartilage is added to the outside edge of existing cartilage.
What is appositional growth?
This is the process by which calcium is released from the bone.
What is bone resorption?
These are the two ways joints are classified.
What is structural and functional?
The knee is an example of this type of joint that allows unilateral movement.
What is a hinge joint?
This cell is responsible for maintaining existing bony matrix.
What is an osteocyte?
This type of ossification begins within the embryonic connective tissue
What is intramembranous ossification?
This hormone is released in response to low Calcium levels in the blood.
What is PTH?
This type of joint consists of two bones joined by hyaline cartilage with little or no movement occurring.
What is a synchondrosis?
This is a pivot joint that allows for rotation of the head.
What is the atlantoaxial joint?
This stem cell can become either an osteoblast or a chondroblas
What is an osteochondral progenitor cell?
This type of ossification begins with a cartilage model.
What is endochondral ossification?
This regulatory molecule's receptor activates precursor cells to become active osteoclast.
What is RANKL?
This type of cartilage lines the ends of bones within a synovial joint.
What is articular cartilage?
This is the act of movement away from the midline of the body.
What is abduction?
This temporary assembly of osteoblasts and osteoclasts travel across the bony surfce remodeling bone.
What is a Basic Multicellular Unit?
This is formed when osteoblasts produce compact bone on the surface of the cartilage model.
What is the bony collar?
This active form of Vitamin D increases blood calcium levels in 3 distinct ways. It increase absorption of calcium in the intestines. It stimulates RANKL production by osteoblasts and it helps prevent the loss of calcium in the urine.
What is Calcitriol?
This is the inner layer of the joint capsule that produces a viscous lubricating fluid.
What is the synovial membrane?
This type of movement only occurs in the thumb.
What is opposition?
This is the origin cell that osteoclasts develop from.
What is Red bone marrow cells?
In bony growth, this zone contains chondrocytes that divide and form columns of cells resembling a stack of plates.
What is the zone of proliferation?
This hormone is secreted from C cells in the thyroid glans when calcium levels are too high.
What is Calcitonin?
This is a pocket of synovial membrance that extends outside the joint cavity to provide cushion between structures that would otherwise rub against each other.
What is a bursa?
This ligament prevents anterior displacement of the tibia in the knee.
What is the anterior cruciate ligament?
