Chapter 1 Flashcards
Define
Anatomy
The science of body structures and the relationships among them.
Define
Physiology
The science of body functions- how the body parts work
Embryology
The first eight weeks of development after fertilization of a human egg
Developmental Biology
The complete development of an individual from fertilization to death
Cell Biology
Cellular structures and functions
Histology
Microscopic structure of tissues
Gross Anatomy
Structures that can be examined without a microscope
Systemic anatomy
Structure of specific systems of the body such as nervous or realities systems
Regional Anatomy
Specific regions of the body such as the head or the chest
Surface anatomy
Surface markings of the body to understand internal anatomy through visualization and palpitation (general touch)
Imaging Anatomy
Internal body structures that can be visualized with techniques such as x-rays, MRI, CT scans, and other technologies for clinical analysis and medical intervention.
Pathological Anatomy
Structural changes (gross to microscope) associated with disease.
Molecular physiology
Functions of individual molecules such as proteins and DNA
Neurophysiology
Functional properties of nerve cells
Endocrinology
Hormones (chemical regulators in the blood) and how they control body functions
Cardiovascular physiology
Functions of the heart and blood vessels
Immunology
The body’s defenses against disease-causing agents
Respiratory physiology
Functions of the air passageways and lungs
Renal physiology
Functions of the kidneys
Exercise physiology
Changes in cell and organ functions due to muscular activity
Pathophysiology
Functional changes associated with disease and aging.
Six levels of organization
Chemical level, cellular level, tissue level, organ level, system level, organismal level
Chemical level
Atoms
Molecules
Cellular level
Cells
Tissue level
Epithelial tissue, connective tissue, muscular tissue, nervous tissue
Epithelial tissue
Covers body surfaces, lines hollow organs and cavities, and forms glands
