Fracture where the bone is only partially broken
Term
Infectious (septic) arthritis
Definition
Form of arthritis caused by bacterial infection
Term
Juvenile rheumatoid arthritis
Definition
Form of arthritis that affects children and young adults. it is more acute, and its systemic effects are greater, than the adult form.
Term
Kyphosis
Definition
Abnormal curvature of the spine, referred to as hunchback
Term
Linear fracture
Definition
Fracture that runs parallel to the long axis of the bone
Term
Linear fracture
Definition
Term
Magnetic resonance imaging (MRI)
Definition
A diagnostic tool for imaging tumors in which magnetic fields and radiofrequency (RF) pulses are used to affect the orientation of hydrogen atoms in the tissue. The changes in the energies of the atoms can then be evaluated and translated into an image of the target
Term
Metastic

Involving the spreading of disease from one organ to another that are not in direct contact with each other
Term

Definition
A protein pigment that stores oxygen in muscle fibers
Term
Necrosis
Definition
The death and degradation of living tissue
Term
Neoplasms
Definition
Any new, abnormal, uncontrolled growth; cancerous tumor
Term
Neuromuscular junction
Definition
Junction between nerve endings and muscle fibers/cells
Term
