Study of Dead Tissue:

1. Gross anatomy - with the naked eye

2. Microscopic anatomy

Light microscope - 1,000 times magnification

Electron light microscope (aka EM) - >30,000 times magnification

Transmissions EM (TEM) - electrons pass through tissue

Scanning EM (SEM) - scans surface of tissue

Study of Live Tissue:

1. Nuclear magnetic resonance (NMR) - anatomy

2. Functional NMR - combines anatomy with physiology; can pick up amount of oxygen in vessels

Example: Different brain centers are active while you’re reading this post than those that are active during sleep, therefore, those active brain centers consume more oxygen than less active brain centers.

3. Positron emission tomography (PET) - uses radioactive material to localize

Note: Can be damaging to organs, especially reproductive organs, which can stunt growth during puberty in adolescents. Typically used as a last resort in diagnosis.
