Anatomy
The study of the form and structure of the body.
Physiology
The examination of how the body functions.
Homeostasis
The ability of an organism to maintain a consistent internal environment despite changing external conditions.
Microscopic Anatomy
The examination of structures that cannot be observed with the unaided eye, requiring a microscope.
Cytology
The study of body cells and their internal structure.
Histology
The study of tissues.
Gross Anatomy
The study of structures visible to the unaided eye.
Systemic Anatomy
The study of the anatomy of each body system.
Regional Anatomy
The examination of structures in a specific body region.
Surface Anatomy
The study of superficial anatomical markings and internal body structures.
Comparative Anatomy
The study of anatomical similarities and differences among different species.
Embryology
The study of developmental changes from conception to birth.
Pathologic Anatomy
The study of anatomic changes resulting from disease.
Negative Feedback
A control mechanism that counteracts changes in a variable, working to bring it back to a set point.
Positive Feedback
A control mechanism that reinforces changes, pushing a variable in the same direction until a climactic event occurs.
Anabolism
The process of joining small molecules to form larger ones.
Catabolism
The process of breaking down large molecules into smaller ones.
Receptor
A component that detects changes in a variable and signals a control center.
Control Center
Interprets input from the receptor and initiates action via an effector.
Effector
The structure that brings about changes to alter the stimulus.
Serotonin
A neurotransmitter known as the 'feel good hormone,' which helps elevate mood.
SSRI (Selective Serotonin Re-uptake Inhibitors)
Drugs that increase serotonin levels in the brain by preventing its reuptake.
diagnosis
The process of identifying a disease or condition based on its signs and symptoms.
prognosis
A forecast about the likely outcome of a disease, including chances of recovery.
symptom
A physical or mental feature indicating a condition or disease.
sign
An objective indication of a disease that can be observed or measured by someone other than the patient, such as a rash or fever.
