Ch 1: Intro To Anatomy&Physiology Flashcards
What is Anatomy?
Study of the STRUCTURAL basis of body function
What is Physiology?
Study of the FUNCTIONAL relevance of human structure
What are the levels of human complexity?
-Subatomic Particles
-Atoms
-Molecule
-Macromolecules
-Organelles
-Cells
-Tissue
-Organs
-Organ Systems
-Organism
What are the Characteristics of Life?
-Metabolism
-Responsiveness
-Reproduction
-Homeostasis
What is Negative feedback?
A change sensed by the body activates mechanisms that reverse it
What is Positive Feedback?
A change sensed by the body is intensified, producing unstable conditions.
Axial Portion
Head, neck, trunk
Appendicular Portion
Upper and lower limbs
What are the major body cavities of the axial portion?
-Cranial Cavity
-Vertebral Canal
-Thoracic Cavity
-Abdominopelvic Cavity
What are the small cavities of the head?
-Cranial Cavity
-Frontal Sinuses
-Orbital Cavities
-Sphenoidal sinuses
-Nasal Cavity
-Middle ear Cavity
-oral cavity
Serous membranes
Double-layered that lines the thoracic and abdominopelvic cavities and secretes serous fluid
Serous fluid
Slippers fluid that prevents friction between the two layers of the serous membranes
Visceral Layer
Inner layer (covers the organ)
Parietal Layer
Outer layer (lines the wall cavity)
