Study Notes
Introduction to Autopsy
- Autopsy (post-mortem) is used to study anatomy and pathology.
- Pathology investigates the cause of disease, its development (pathogenesis), and the structural changes in cells.
Basic Anatomy Review
-
Directional Terminology:
- Anterior: front
- Posterior: back
- Caudal: towards the tail
- Rostral: towards the head end
- Dorsal: situated on or near the back
- Ventral: belly
- Proximal: closest to the heart or point of attachment
- Distal: opposite of proximal
- Supine: facing upwards
- Prone: facing down
- Palmar: palm of the hand
- Plantar: bottom of the foot
-
Epithelia:
- Covers all exposed surfaces of the body
- Provides protection from damage, fluid loss, and foreign bodies
- Involved in metabolic functions (metabolite exchange, ion transport, glandular secretion)
- Directly interacts with the outside environment
- 90% of cancers occur in epithelial tissue
- Example: Podocytes - epithelial cells in the kidney that control protein movement
-
Muscle Tissue:
-
Skeletal Muscle:
- Striated appearance
- Responsible for coordinated movement and force generation
-
Cardiac Muscle:
- Intercalated discs allow for coordinated contraction
-
Smooth Muscle:
- Spindle-shaped cells
-
Skeletal Muscle:
-
Connective Tissue:
-
Adipose:
- Loose tissue, designed to store lipids
-
Bone:
- Highly organized for strength and rigidity
-
Tendon:
- Elongated fibers for force transmission
- Flattened cells withstand pressure
-
Blood Cells:
- Diverse functions in immune and inflammatory responses, oxygen and carbon dioxide transport, and coagulation
-
Adipose:
-
GI Tract Layers:
-
Mucosa:
- Epithelial layer
- Supporting lamina propria
- Muscularis mucosa
- Submucosa
- Muscularis (propria)
- Adventitia
-
Mucosa:
-
Mucosa Structure and Function:
-
Oesophagus:
- Protective, stratified squamous epithelium
-
Stomach:
- Secretory, tubular glands
-
Small Intestine:
- Absorptive, villi and short glands (crypts)
-
Large Intestine:
- Absorptive and protective, tubular glands and mucus-secreting goblet cells
-
Oesophagus:
-
Circulatory System:
- Heart structure and blood flow
- Structure of blood vessels
