Study Notes

Introduction to Anatomy and Physiology

Anatomy refers to the structure of the body, derived from the Greek phrase meaning "to take apart."
Physiology explores the function of the body's systems and processes, meaning "study of natural phenomena."
Principle: Form follows function; specific shapes are designed to accomplish particular tasks.

Anatomical Positions

Anatomical Position: Individual faces the observer with head level, lower limbs parallel, upper limbs at sides, and palms facing forward.
Prone Position: Individual lies flat face down, back facing upwards.
Supine Position: Individual lies flat face up, back facing the ground.

Sectional Planes

Sagittal Plane: Divides the body into left and right sections; midsagittal for equal parts, parasagittal for unequal parts.
Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back) sections.
Transverse (Horizontal) Plane: Divides the body into superior (upper) and inferior (lower) sections.
Oblique Plane: Cuts the body along a diagonal, different from the standard planes.

Directional Terms

Superior/Cephalic/Cranial: Toward the head.
Inferior/Caudal: Toward the feet.
Anterior/Ventral: At or near the front.
Posterior/Dorsal: At or near the back.
Medial: Near the midline of the body.
Lateral: Near the side.
Superficial/External: Toward the surface.
Deep/Internal: Away from the surface.
Proximal: Nearer to the attachment point of a limb.
Distal: Further from the attachment point of a limb.

Anatomical Terminology

Essential for effective communication among healthcare professionals.
Levels of Organization:
- Molecular: Chemical structures.
- Cellular: Made of molecules.
- Tissue: Composed of cells (types: epithelial, muscle, nervous, connective).
- Organ: Comprises tissues.
- System: Made up of organs.
- Organism: All body systems together.

Origins of Anatomical Terms

Derived from Greek, Latin, and English.
Reflect body regions (e.g., femur = thigh), shapes (e.g., foramen magnum), functions (e.g., flexor digitorum), and discoverers (e.g., vein of Galen).

Planes and Directions

Coronal Plane: Also called frontal.
Sagittal Plane: Longitudinal section.
Transverse Plane: Cross-sectional view.
Key imaging views standard during MRI and CT scans consider patient positioning.
Body Directions:
- Proximal: Closer to point of attachment; knee is proximal to ankle.
- Distal: Further from point of attachment; ankle is distal to knee.
- Deep: Internal structures, buried within.
- Superficial: Near the body's surface.
- Parietal: Relates to body walls.
- Visceral: Pertains to organs.

Movements

Palms face forward in the anatomical position.
Flexion: Moving a body part forward (anterior).
Extension: Moving a body part backward (posterior).

Body Cavities

Serve as surface anatomy references for deep organs.
Thoracic Landmarks: Include ribs, lungs, and mediastinum (area containing the heart and trachea).
Abdominal Quadrants: Include right upper, right lower, left upper, left lower.
Nine Abdominal Regions: Further subdivides abdomen for anatomical clarity.
Body cavities are potential spaces; organs reside in their respective locations, not within cavities.
Viscera: Refers to organs inside the cavities.
Parietal: Relates to the body wall surrounding the cavities.
