Chap 1 Flashcards
6 basic functions that all living things preform
Responsiveness Adaptability to environment Growth Reproduction Movement Metabolism
Anatomy
study if the structure and shape of our body and its parts
Gross Anatomy
the study of large structures (heart, organs, bones)
Microscopic Anatomy
the study of smaller structures (cells and tissues)
Physiology
the study of how our body’s function
Homeostasis
the body’s ability to maintain a constant environment
Diff levels of gross anatomy
Surface Regional Systemic Developmental Clinical Pathological Radiography Surgical
Diff levels of physiology
Cell: living cells
Systemic: major organ systems
Pathology: effects of disease on organ/systems
Microscopic Anatomy
Cellular Level- light microscope
Molecular Level-electron microscope
Cytology
study of the internal structures of cells
Histology
examines tissues
Anatomical Position
standing straight-up, arms to side, palms facing out
Superior
Towards the head, above
Inferior
Away from the head, below
Anterior
Toward the front, in front of
Posterior
Toward the back, behind
Supine
Lying on back
Prone
Lying on stomach
Median
Equal cuts left and right
Frontal
Equal anterior and posterior
Transverse
Superior and Inferior
What does the Diaphragm separate
Thoracic cavity and abdominopelvic cavity
Outside Pleura
Parietal Pleura
Inside Pleura
Visceral Pleura
Homeostasis requires…..
Receptor
Control Center
Effector
Negative Feedback loop
an automatic response to a stimulate leading to a variation outside the normal limits
-primary mechansim of homeostatic regulation
Positive Feedback Loop
- provides the regulation of a potentially dangerous or stressful process
- extreme repsonses
Cell Theory
- Cells are structural building blocks
- produced by division
- preform all vital functions
Most homeostatic control systems use
negative feedback mechanisms
Parasagittal
unequal cuts of left and right
