Human anatomy is the study of the structure of the human body.
Human physiology is the study of the mechanical, physical, and biochemical processes that support the body's function.
Homeostasis is maintained by the body's responses to adverse stimuli, ensuring maintenance of an optimal physiological environment.
If positive and negative feedback loops are affected or altered, homeostatic imbalance and resultant complications can occur.
When an organism is in its standard anatomical position, positional descriptive terms are used to indicate regions and features.
Positional terms give precise descriptions of anatomical relationships and allow for consistency when referencing anatomical positions.
Regional directional terms include anterior and posterior, dorsal and ventral, and lateral and medial.
There are three basic reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane.
Vertebrates have fluid-filled spaces called body cavities that contain the organs.
A number of membranes enclose the various organs of the human body.
The abdomen is subdivided into four quadrants and nine areas.
Medical imaging is used to create images of the human body used for clinical purposes, diagnostic procedures or medical science.
An autopsy or post-mortem examination is a specialized surgical procedure to determine cause of death.
Medical diagnosis refers to the process of attempting to identify a possible disease or disorder in a patient who has symptoms.
Descriptive research refers to the measurement of behaviors and attributes through observation rather than through experimental testing.
Correlational research can be used to see if two variables are related and to make predictions based on this relationship.
Experimental research tests a hypothesis and establishes causation by using independent and dependent variables in a controlled environment.
Observational studies allow researchers to document behavior in a natural setting and witness events that could not be produced in a lab.
A case study is a method of obtaining in-depth information on a person, group or phenomenon to provide descriptions of specific or rare cases.
Surveys are a low-cost option for gathering a large amount of data, but they are also susceptible to reporting bias.
Ethical guidelines in psychological research serve to minimize harm to participants' mental and physical well-being.
Animal research raises the controversial question of whether it is ethical to harm animals with the aim of improving human lives.
Research studies with small sample sizes, high variability, and sampling bias are usually not representative of the general population.
