Study Notes

Anatomy

Study of the structure and shape of the body and its parts, and their relationships
Comes from Greek words meaning "to cut apart"
Examines the structure and relationships among body parts
Involves separating parts to determine position, relations, and structure
Understanding anatomy helps determine functions

Physiology

Study of how the body and its parts function
Includes subdivisions like neurophysiology (nervous system) and cardiac physiology (heart)
Studies the normal function of the human body (maintaining life)
Examines the chemistry and physics of body structures and how they work together

Relationship between Anatomy and Physiology

Structure dictates function
Example: Lungs are thin-walled, not muscular, allowing for gas exchange, unlike the muscular heart.

Divisions of Anatomy

Gross Anatomy: Structures visible to the naked eye (muscles, bones, organs)
Surface Anatomy: Structures seen on the body's surface
Regional Anatomy: Internal structures of a specific body region (e.g., arm)
Systemic Anatomy: Structures making up a body system (e.g., cardiovascular system)
Microscopic Anatomy: Structures requiring a microscope (cells, tissues)

Characteristics of Life

Organization: Living things are made of cells, organized in a hierarchical manner
Responsiveness: Ability to react to changes internally and externally (e.g., sweating in response to heat)
Movement: Includes the motion of organs and individual cells.
Development and Growth: Changes in structure & function throughout life, including differentiation (cells becoming specialized)
Reproduction: Creation of new organisms
Metabolism: Breaking down and building up of molecules for energy and growth
Growth: Increase in body size.
Genes (Heredity): Traits passed from parents to offspring
Homeostasis: Maintains internal conditions (balance of fluids and chemicals)

Levels of Organization

Atoms: Simplest building blocks of matter (proton, electron, neutron)
Molecules: Formed by combinations of atoms (e.g., water)
Cells: The basic functional and structural units of living organisms
Tissues: Groups of similar cells working together
Organs: Structures composed of two or more tissue types
Organ Systems: Groups of organs with related functions
Organism: A complete living individual

Other Details

Organelles: Tiny functioning units within cells
System: Group of organs that work together
