Chapter 1: Major Themes of Anatomy and Physiology Flashcards
4 ways of examining structure of the human body
- Inspection
- Palpation
- Auscultation
- Percussion
Cutting and separation of tissues to reveal their relationships
Cadaver Dissection
Study of more than one species in order to examine structural similarities and differences and to analyze evolutionary trends
Comparative anatomy
Opening of the body to look inside
Exploratory Surgery
Viewing inside the body without surgery
Medical Imaging
Branch of medicine concerned with imaging
Radiology
Study of structures that can be seen with naked eye
Gross Anatomy
Study of structure and function of cells
Cytology
Study of tissues and examination of cells with microscope
Histology (Microscopic Anatomy)
Molecular detail seen in electron microscope
Ultrastructure
Microscope examination of tissues for signs of disease
Histopathology
Subdisciplines of physiology
- Neurophysiology
- Endocrinology
- Pathophysiology
Type of physiology that is the study of different species to learn about bodily function and is the basis for the development of new drugs and medical procedures
Comparative physiology
Greek physician who established a code of ethics also known as the “father of medicine”
Hippocrates
Published the first atlas of anatomy in 1543
Andreas Vesalius
First to see and named ‘cells’ Also made many improvements to compound microscope and his microscopes magnified only 30x.
Robert Hooke
Physician to the Roman gladiators who wrote the most influential medical textbook
Galen
Invented a simple (single-lens) microscope with great magnification to look at fabrics (200x) and also published his observations of blood, lake water, sperm, bacteria from tooth scrapings, and many other things.
Antony van Leeuwenhoek
First tenet of cell theory which was considered as the most important breakthrough in biomedical history,
Matthias Schleiden and Theodor Schwann

- Organ
- Tissues
- Cells

Characteristics of life
- Organization
- Cellular composition
- Metabolism
- Responsiveness and movement
- Homeostasis
- Reproduction
- Evolution
The body’s ability to detect change, activate mechanisms that oppose it, and thereby maintain relatively stable internal conditions
Homeostasis
When the body senses a change and activates mechanisms to reverse it.
Negative feedback loop
Self amplifying cycle that leads to a greater change in the same direction; feedback loop is repeated.
Positive feedback loop
3 Components of a feedback loop
- Receptor
- Integrating Control Center
- Effector
Penetrate tissues to darken photographic film beneath the body, dense tissue appears white, over half of all medical imaging, and until 1960s, it was the only method widely available.
X-rays
Injected or swallowed, fill hollow structures such as blood vessels or intestinal tract.
Radiopaque substances
Low intensity X rays and computer analysis, slice type image, and increased sharpness of image. Formerly called CAT scan.
Computed Tomography (CT scan)
Assesses metabolic state of tissue
Positron Emission Tomography (PET scan)
Slice type image Superior quality to CT scan Best for soft tissue
Magnetic Resonance Imaging (MRI)
Uses high-frequency sound waves that echo back from internal organs, avoids harmful x rays, is second oldest and second most widely used but the image is not very sharp
