PATHALOGY OF INJURY AND DISEASE
CLASSIFICATION OF BODY TISSUE
Nerve Tissue
Can lead to physical disability, paraplegia
or quadriplegia
Nerve tissue provides sensitivity and
communication from CNS to muscles and
sensory organs.
Muscle tissue
Muscle healing
Within a few days there is vascular
proliferation and myoblastic cell
formation occur.
Follow the same healing process
as vascular tissue.
Muscle Strains
Grade 1: Some muscle or tendons
are actually torn. Pain and tenderness.
Grade 2: Some of muscle or tendon
have been torn. Active movement is
painful.
Grade 3: Total rupture of tendons.
Total lost or impairment of the limb.
Tendon is over stretched, exceeding
the normal ability.
Connective Tissue
Support and provide body framework, fill space, storage of fat,
protect against infection and help repair tissues.
Ephitelial Tissue
Fundamental tissue that covers internal & external body surfaces such as skins, outer layer of internal organs, and inner lining of blood vessels.
WHAT IS PATHOLOGY
Pathology deals with knowledge of what causes disease, how
disease starts, progresses.
FACTORS INFLUENCE HEALING
PROCESS
Health, Age And Nutrition
Poor Vascular Supply
Edema
Muscle Spasm
THE HEALING
PROCESS
Maturation-remodeling phase
Might take several years to complete.
Scar is visible.
Involve long term process.
Fibroblastic-Repair Phase
Increased oxygen and nutrients to injured site
fibroplasma begins first few hours after injury and lasted
as long as 4-6 weeks.
Scar formation occurs
Inflammatory Response phase
This process includes transportation of leukocytes and phagocytic
cells to injured tissue
Characterized by redness, swelling, tenderness and increased
temperature.
Once tissue injured, healing process starts immediately.
PRIMARY INJURY
Microtrauma is chronic overuse or repetitive injuries.
Macrotrauma is acute and produce immediate pain and disability.
macrotrauma or microtrauma forces
