Study
1
Question
Anatomy
Answer
The study of the structure of the body with an emphasis on how it relates to function.
2
Question
Histology
Answer
Taking samples of tissues and viewing them under a microscope.
3
Question
Surface Anatomy
Answer
The external structure of the body and is especially important in conducting a physical examination of a patient.
4
Question
Systemic Anatomy
Answer
The study of one organ at a time.
5
Question
Regional Anatomy
Answer
The study of multiple organ systems at the same time in a given region of the body.
6
Question
Radiologic Anatomy
Answer
The study of the body using medical imaging.
7
Question
Gross Anatomy
Answer
The study of structures visible to the naked eye either by surface observation or dissection.
8
Question
Comparative Anatomy
Answer
The study of the similarities and differences in the anatomy of different species.
9
Question
Physiology
Answer
The study of dynamic processes in the living body and how organisms function.
10
Question
Inspection
Answer
Looking at the surface of the body.
11
Question
Dissection
Answer
Cutting and separating tissues to reveal relationships between structures.
12
Question
Palpation
Answer
Feeling structures with fingertips. Example: Feeling a pulse.
13
Question
Auscultation
Answer
Listening to natural sounds made by the body. Example: Heartbeats.
14
Question
Percussion
Answer
Tapping on the body and listening to the sound for signs of abnormalities. Can also be used to check reflexes.
15
Question
Medical Imaging
Answer
Methods of viewing the inside of the body without surgery. Includes CT, MRI, PET, and Sonography.
16
Question
CT (Computed Tomography)
Answer
Patient is moved through a ring-shaped machine that emits low-intensity x-rays on one side and receives them with a detector on the opposite side. Produces an image of a slice of the body as thin as a coin. Ideal for imaging thin sections of the body with little organ overlap. Image is sharper than conventional x-ray.
17
Question
MRI (Magnetic Resonance Imaging)
Answer
Patient lies in a tube or open-sided scanner with a powerful electromagnet. Hydrogen atoms in the body align themselves with the magnetic field, generating signals that the computer analyzes to produce an anatomical image. Better than CT for visualizing soft tissues. Disadvantages include claustrophobia and long exposure times.
18
Question
fMRI (functional MRI)
Answer
A type of MRI that visualizes moment-to-moment changes in tissue function.
19
Question
PET (Position Emission Tomography)
Answer
Used to assess the metabolic state of a tissue and distinguish which areas are most active. Uses an injection with radioisotopes to highlight the tissues that are most actively consuming energy at the moment of the scan.
20
Question
Sonography
Answer
Uses a device placed on the skin which emits high-frequency ultrasound and receives signals reflected back from internal organs. Equipment is inexpensive and portable. Useful for imaging motion.
21
Question
Physiology
Answer
The study of how the body functions.
22
Question
Neurophysiology
Answer
The study of how the nervous system functions.
23
Question
Pathophysiology
Answer
The study of the mechanisms of disease.
24
Question
Comparative Physiology
Answer
The study of the similarities and differences in the physiology of different species.
25
Question
Characteristics that define being alive
Answer
Organization, Cells, Metabolism, Development, Differentiation, Growth, Excitability, Homeostasis, Reproduction, Evolution.
26
Question
Homeostasis
Answer
The ability of an organism to maintain stable internal conditions.
27
Question
Negative Feedback
Answer
A mechanism in which the body senses a change and activates mechanisms that negate it, keeping the body at a set point.
28
Question
Dynamic Equilibrium
Answer
A state of ever-changing balance within limits.
29
Question
Positive Feedback
Answer
A self-amplifying cycle where the change leads to an even greater change in the same direction. Example: Childbirth, blood clotting, high fever.
30
Question
Atoms, Molecules, Organelles, Cells, Tissue, Organs, Organ Systems, Organism
Answer
Levels of organization in the body.
