Definitions:
- Anatomy: The study of human structures.
- Physiology: The study of how these structures function, or what they do.
Anatomical Structures and Examples:
- Examples of anatomical references:
- Brachial muscle (upper arm muscle)
- Antecubital region (front of elbow)
- Patella (kneecap)
- Organs like the liver and spleen.
Historical Context of Anatomy:
- Much of anatomical knowledge was derived from unethical practices (live dissections of subjects like convicted criminals).
- Public dissections were held in auditoriums to educate viewers.
- Cadaver studies provide important hands-on learning opportunities (e.g., viewing cadavers in labs).
Viewing Cadavers:
- Cadaver room:
- Provides an opportunity to see the human body beyond textbooks.
- Students are not required to participate; feelings of discomfort should be respected.
- Warning about potential odors from preserved tissue (sharp/noxious).

Modern Techniques for Viewing Structures:
- Imaging methods include:
- Magnetic Resonance Imaging (MRI)
- Computed Tomography (CT) scans
- Positron Emission Tomography (PET) scans
- Electroencephalography (EEG)
- Electrocardiography (ECG)
- Electromyography (EMG)
- Purpose: To visualize internal structures without invasive procedures.

Function of Structures:
- Physiology studies how structures function, an example being muscle contraction.
- Key proteins involved:
- Actin: Thin filament involved in muscle contraction.
- Myosin: Thick filament responsible for muscle contraction.
- Titin: A large protein that contributes to the elasticity and stability of muscle.
Process of Muscle Contraction:
- Interaction between actin and myosin enables muscle shortening and voluntary movement.
- Energy source for contractions: Adenosine
