Term
Flat Bones
Definition

Have thin and roughly parallel surfaces. They provide protection for unerlying soft tissues and offer an extensive surface area for the attachment of skeletal muscles.

 

Term
Sutural Bones
Definition

Term
Long Bones
Definition
Are relatively long and slender. Located in the arm and forearm,thigh and leg,palms,soles,fingers and toes.
Term
Irregular Bones
Definition
Irregular bones have complex shapes with short,flat,notched, or ridged surfaces. Bones in the pelvis and spinal vertebrae are irregular bones.
Term
Short Bones
Definition
Short Bones are usually boxy and small. Bones in wrists and ankles are examples of short bones.
Term
Osteocytes
Definition
Mature bones cells that maintain the protein and mineral content of the surrounding matrix.
Term
Osteoclasts
Definition
Cells that remove and recycle bone matrix.
Term
Functions of Skeletal System
Definition
Support,Storage of Minerals,Blood Cell Production,Protection and Leverage.
Term
Lamellae
Definition
Layers of the matrix
Term
Ossification Center
Definition
Location where ossification begins
Term
Endosteum
Definition
An imcomplete cellular layer that lines the medullary cavity.
Term
Interstitial Lamellae
Definition
Fill in the spaces between the osteons in the compact bone.
Term
Spongy Bone
Definition
Located where bones are not heavily stressed or where stresses arrive from many directions.
Term
Nutrient Foramen
Definition
A tunnel that penetrates the diaphysis and provides access for the nurtient artery and/or vein
Term
Articular Cartilage
Definition
Covers portions of the epiphysis that articulate with other bones.The cartilage is avascular and it relies primarily on diffusion from the synovial fluid to obtain oxygen and nutrients and eliminate wastes.
Term
Diaphysis
Definition
Also known as the shaft of the elongated body of the long bone.
Term
Fossa
Definition
Shallow depression or recess in the surface of the bone.
Term
Epiphysis
Definition
Expanded area found at each end of the bone.
Term
Facet
Definition
A small, flat articular surface.
Term
Process
Definition
Any projection or bump.
Term
Fissure
Definition

Term
Sulcus
Definition
Is a deep narrow groove.
Term
Condyle
Definition
Is a smooth, rounded articular process.
Term
Yellow Bone Marrow
Definition
Is adipose tissue important in the storage of energy reserves.
Term
Epiphyseal Cartilage
