A rope like protein found in the extracellular matrix of bone, cartilage, tendons, and ligaments
What is collagen?
The main shaft of the long bone
What is the Diaphysis?
Four types of bones characterized by their shape
What are Long bones, short bones, flat bones, and irregular bones?
Calcium phosphate crystals that make up most of the mineral in bone.
What is hydroxyapatite?
In adults, the “growth plate” becomes what is known as the
What is the epiphyseal line?
This forms most of the diaphysis of long bones and the thinner, outer surfaces of all other bones.
What is Compact bone?
Most of the lamellae of compact bone are in concentric rings surrounding a central canal (that contains blood vessels), termed this.
What is the Haversian Canal?
Bone is formed in thin sheets of extracellular matrix called this
What are Lamellae?
In cancellous bone, the delicate interconnecting rods and or plates of bone are called
What are trabeculae?
In both compact and cancellous bone, nutrients gain access to bone cells (either through the central canal or through spaces within trabeculae) via a process known as
What is diffusion?
Sutures, syndesmoses and gomphoses are types of
What are fibrous joints?
A freely movable joint, the knee and hip joint are two good examples, are known as
What are synovial joints?
The main purpose of synovial fluid found within the joint capsule of all synovial joints
What is to provide lubrication/reduce friction?
Found at the tips (outermost portion) of each bone meeting in a synovial joint
What is articular cartilage? EC – What type of cartilage is articular cartilage?
Structure that produces the synovial fluid
What is the synovial membrane?
The process of bone formation by osteoblasts
What is ossification?
Primarily occurring in the skull, this process results from osteoblasts producing bone from connective tissue membranes.
What is intramembranous ossification?
Most of the bones of the body develop from this type of ossification where osteoblasts build bone from cartilage models.
What is endochondral ossification?
These are cartilage cells
What are chondrocytes?
As chondrocytes lay hyaline cartilage in layers during bone growth, hypertrophy and death occurs to chondrocytes on this side of the bone
What is the diaphyseal side?
The skull, the vertebral column and the thoracic cage are considered to be the
What is the axial skeleton?
The central axis extending from the base of the skull to the end of the pelvis is known as the
What is the vertebral column?
The many crevices and cavernous areas found within the nasal cavities are known as
What are the sinuses?
The cone-shaped depressions found in the face, which hold what some would call the structures that provide the “window to the soul” are called
What are the orbits?
Any hole in a bone, especially where a nerve or blood vessel may pass through, is known as a
What is a foramen? EC – What is the name of the hole at the base of the skull where the spinal cord meets the brainstem?
