The study of the structure of body parts and their relationships to one another.
The study of the functions of the body, or how the body parts work and carry out their life sustaining activities.
Principle of Complementarity:
What a structure can do depends on it's specific form. STRUCTURE DETERMINES FUNCTION. (This is the theme of the course)
Breakdown into simpler substances
Synthesis of more complex substances from simple ones.
Necessary Life Functions:(8 total)
1. MAINTAINING BOUNDARIES: Cell Membrane, integumentary system
What are the SURVIVAL NEEDS for the body?
Nutrients, Oxygen, Water, Normal Body Temperature, Atmospheric Pressure.
Name the different levels of Structural ORGANIZATION that make up the human body and explain their relationships.
Chemicals (atoms, molecules), Cells, Tissues, Organs, Organ Systems, Organisms.
Define HOMEOSTASIS and explain its significance:
HOMEOSTASIS: is the ability to maintain relatively stable internal conditions even though the external conditions are continuously changing.
How do NEGATIVE and POSITIVE FEEDBACK maintain body homeostasis?
NEGATIVE FEEDBACK: (Most Homeostatic controls are negative) The output shuts off the original effect of the stimulus or reduces its intensity. These mechanisms cause the variable to change in a direction OPPOSITE to that of the initial change, returning it to its "ideal" value. Like a thermostat. (Ex. Blood glucose levels)
Describe the relationship between HOMEOSTATIC IMBALANCE and disease.
results in disease or aging, due to the body's inability to maintain a stable environment.
Describe the ANATOMICAL POSITION.
Body erect, arms at sides, legs together, palms face up. (Allows proper orientation of the parts of the body that gives us one directional reference point)
Use correct anatomical terms to describe BODY DIRECTIONS and REGIONS.
DIRECTIONAL TERMS: allows us to explain where one body structure is in relation to another.
Use correct anatomical terms to describe BODY PLANES and SECTIONS.
FRONTAL (coronal): Divides into front and back halves (Like a CT Scan)
Locate the name the MAJOR BODY CAVITIES and their SUBDIVISIONS, and list the MAJOR ORGANS contained within them.
CRANIAL: Contains Brain
Describe the specific SEROUS MEMBRANES and indicate their common function.
(like a fist in a balloon) A double layered membrane with fluid in the cavity between layers. It allows organs to move without friction (heart, lungs, etc.)
Serous Membranes in Ventral Body Cavity:
PARIETAL PLEURA: Lines the walls of the thoracic cavity
Name the FOUR QUADRANTS of the Abdominopelvic cavity and list the organs it contains.
Name the NINE REGIONS of the Abdominopelvic cavity and list the organs it contains.
