Untitled Deck Flashcards
(32 cards)
What is Anatomy?
The study of structure, including what it is, what it looks like, and where it’s located.
What is Physiology?
The study of function, including how it works and how it supports life.
What does the statement ‘Function always reflects structure’ imply?
The way an anatomical structure is built influences how it functions.
What is Gross (Macroscopic) Anatomy?
The study of structures visible to the naked eye.
What is Regional Anatomy?
The study of all structures in a specific body region, such as the head or arm.
What is Systemic Anatomy?
The study of one system at a time, such as the cardiovascular system.
What is Surface Anatomy?
The study of external features linked to deeper structures.
What is Microscopic Anatomy?
The study of structures that require magnification, including cytology and histology.
What is Developmental Anatomy?
The study of changes over time, including embryology.
What is Comparative Anatomy?
The study of anatomical differences across species.
What is Pathological Anatomy?
The study of structural changes resulting from disease.
What is Clinical Anatomy?
The application of anatomy in diagnosis and treatment.
What is the best use of X-Ray imaging?
To visualize bones and dense tissues.
What are the key features of a CT Scan?
Provides 3D cross-sections and is best for soft tissues and trauma.
What does MRI stand for and what are its key features?
Magnetic Resonance Imaging; uses magnetic fields, no radiation, slower than CT.
What is a PET Scan used for?
To assess metabolic activity, often in cancer and brain studies.
What is an Ultrasound and its key feature?
Uses sound waves to visualize organs and is safe and portable.
List the levels of structural organization from smallest to largest.
- Chemical
- Cellular
- Tissue
- Organ
- Organ System
- Organism
What is Homeostasis?
Maintaining internal balance despite external change.
What are the components of a homeostatic mechanism?
- Receptor: detects change
- Control Center: determines action
- Effector: carries out correction
What is Negative Feedback?
A mechanism that reverses change to restore balance.
Give an example of Negative Feedback.
Body temperature regulation, blood glucose levels, blood pressure.
What is Positive Feedback?
A mechanism that enhances change to completion.
Give an example of Positive Feedback.
Childbirth and blood clotting.
