Tissues and Organs of the Skeletal System | Histology of Osseous Tissue | Bone Development | Mineral Deposition and Resorption | Bone Disorders |
---|---|---|---|---|
What is the skeletal system?
The body system that is composed of bones, cartilages, and ligaments joined tightly to form a strong, flexible framework for the body.
|
What is collagen?
This is a protein based organic molecule that provides resistance and flexibility in bone; prevents tensile force
|
What is intramembranous ossification?
This type of ossification produces the flatbones of the skull as well as the clavicle
|
What is mineral deposition?
This is he crystallization process in which calcium, phosphate, and other ions are taken from the blood plasma and deposited in bone tissue
|
What is orthopedics?
This is the branch of medicine concerned with bone disorders; Deals with the prevention and correction of bone, joint, and muscle injuries
|
What are short bones?
These types of bones have equal heights and widths; examples are carpal and tarsal bones
|
What is an osteogenic cell?
Found in the endosteum and inner layer of the periosteum, these cells from the embryonic mesenchymal cells are bone generating
|
What is endochondral ossification?
This is a process in which a bone develops from a preexisting model of hyaline cartilage and is the process in which most bones develop
|
What is hypocalcemia?
This is a condition resulting from a deficiency of calcium in the blood
|
What is a pathological fracture?
Type of fracture where there is a break in bone weakened by some other disease and usually caused by a stress that would not normally fracture a bone
|
What is compact bone?
Feature of the long bone that composes the outer shell
|
What is an osteocyte?
These are former osteoblasts that have been trapped in the matrix they deposited
|
What is Wolffs law of bone?
This law states that the architecture of a bone is determined by the mechanical stresses placed upon it, and the bone thereby adapts to withstand those stresses.
|
What is calcitriol?
This is a form of vitamin D that behaves as a hormone that raises blood calcium concentration
|
What is a greenstick fracture?
This type of fracture in which the bone is incompletely broken on one side but merely bent on the opposite side
|
What is spongy bone?
This type of bone is a loosely organized form of osseous tissue found at the ends of long bones
|
What is an osteoclast?
This is a macrophage of the bone surface that dissolves the matrix and returns minerals to the extracellular fluid; this also produces acid and enzymes to break down bone
|
What is the zone of calcification?
The name of the zone where minerals are deposited in the matrix and cells secrete bone around them
|
What is the parathyroid hormone?
This hormone is secreted by the parathyroid glands when blood calcium is low
|
What is closed reduction?
A type of treatment of a fracture, this is a procedure in which the bone fragments are manipulated into their normal positions without surgery
|
What is calcification?
Also known as mineralization, this is the hardening of the matrix of connective tissue by the depositions of calcium phosphate and other minerals
|
What are perforating canals?
Also known as volkmann's canals, these canals are transverse or diagonal passages that join to the central canal
|
What is the epiphyseal plate?
By your 20's all cartilage in this plate will have been consumed
|
What is rickets?
Disease due to the deficiency of calcium in the blood resulting in a softness of bone in children
|
What is osteomyelitis?
A bone disorder where there is an inflammation of osseous tissue and bone marrow as a result of a bacterial infection
