Tissues and Organs of the Skeletal System Histology of Osseous Tissue Bone Development Mineral Deposition and Resorption Bone Disorders
100
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.
100
What is collagen?
This is a protein based organic molecule that provides resistance and flexibility in bone; prevents tensile force
100
What is intramembranous ossification?
This type of ossification produces the flatbones of the skull as well as the clavicle
100
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
100
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
200
What are short bones?
These types of bones have equal heights and widths; examples are carpal and tarsal bones
200
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
200
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
200
What is hypocalcemia?
This is a condition resulting from a deficiency of calcium in the blood
200
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
300
What is compact bone?
Feature of the long bone that composes the outer shell
300
What is an osteocyte?
These are former osteoblasts that have been trapped in the matrix they deposited
300
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.
300
What is calcitriol?
This is a form of vitamin D that behaves as a hormone that raises blood calcium concentration
300
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
400
What is spongy bone?
This type of bone is a loosely organized form of osseous tissue found at the ends of long bones
400
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
400
What is the zone of calcification?
The name of the zone where minerals are deposited in the matrix and cells secrete bone around them
400
What is the parathyroid hormone?
This hormone is secreted by the parathyroid glands when blood calcium is low
400
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
500
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
500
What are perforating canals?
Also known as volkmann's canals, these canals are transverse or diagonal passages that join to the central canal
500
What is the epiphyseal plate?
By your 20's all cartilage in this plate will have been consumed
500
What is rickets?
Disease due to the deficiency of calcium in the blood resulting in a softness of bone in children
500
What is osteomyelitis?
A bone disorder where there is an inflammation of osseous tissue and bone marrow as a result of a bacterial infection
