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.
