PATHALOGY OF INJURY AND DISEASE

PRIMARY INJURY

macrotrauma or microtrauma forces

Macrotrauma is acute and produce immediate pain and disability.

Microtrauma is chronic overuse or repetitive injuries.

Inflammatory Response phase

Once tissue injured, healing process starts immediately.

Characterized by redness, swelling, tenderness and increased
temperature.

This process includes transportation of leukocytes and phagocytic
cells to injured tissue

Fibroblastic-Repair Phase

Scar formation occurs

fibroplasma begins first few hours after injury and lasted
as long as 4-6 weeks.

Increased oxygen and nutrients to injured site

Maturation-remodeling phase

Involve long term process.

Scar is visible.

Might take several years to complete.

Muscle Spasm

Edema

Poor Vascular Supply

Health, Age And Nutrition

Pathology deals with knowledge of what causes disease, how
disease starts, progresses.

Ephitelial Tissue

Fundamental tissue that covers internal & external body surfaces such as skins, outer layer of internal organs, and inner lining of blood vessels.

Connective Tissue

Support and provide body framework, fill space, storage of fat,
protect against infection and help repair tissues.

Muscle tissue

Muscle Strains

Tendon is over stretched, exceeding
the normal ability.

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.

Muscle healing

Follow the same healing process
as vascular tissue.

Within a few days there is vascular
proliferation and myoblastic cell
formation occur.

Nerve Tissue

Nerve tissue provides sensitivity and
communication from CNS to muscles and
sensory organs.

Can lead to physical disability, paraplegia
or quadriplegia
