Study Notes

Positron Emission Tomography (PET)

Utilizes a radioactive tracer introduced into the body for imaging purposes.
Tracers are absorbed by tissues to visualize metabolic activity.

Endoscopy

A procedure for the visual examination of internal organs or cavities.
Involves a lighted instrument known as an endoscope.

Branches of Physiology

Molecular Physiology: Focuses on the functions of individual molecules like proteins and DNA.
Exercise Physiology: Examines changes in cell and organ functions resulting from muscular activity.
Pathophysiology: Studies functional changes related to disease and aging.

Physiological Studies by Body Systems

Neurophysiology: Investigates properties of nerve cells.
Endocrinology: Analyzes hormones and their regulatory effects on the body.
Cardiovascular Physiology: Studies the functions of the heart and blood vessels.
Immunology: Explores the body's defenses against disease-causing agents.

Anatomy

Derived from Greek terms meaning "to cut" and "apart," focusing on body structure and relationships.
Structure is designed to fulfill specific functions, emphasizing the close relationship between anatomy and physiology.

Gross or Macroscopic Anatomy

Involves the study of larger structures visible to the naked eye.
Approaches include:
- Regional Anatomy: Focus on specific body regions (e.g., head and neck).
- Systemic Anatomy: Focus on specific body systems (e.g., digestive).

Surface Anatomy

Studies external body features for clinical assessment.
Example: Palpating breastbone and ribs for heart region identification.

Variant Anatomy

Refers to deviations from the typical anatomical arrangement without affecting function.
Example: Sternal foramen, a common anatomical anomaly.

Microscopic Anatomy

Involves structures not visible to the naked eye, viewed only through a microscope.
Subdivisions:
- Cytology: The study of cellular structures.
- Histology: The comprehensive study of tissue structures.

Embryology

Focuses on the study of embryo development during the first week post-fertilization.
Concerns developmental changes occurring before birth.

Developmental Biology

Examines the complete development of an individual from fertilization to death.
Traces structural changes throughout the life span.

Pathology

Studies both gross and microscopic structural changes due to disease.
The term "pathos" means disease, highlighting the focus on pathological alterations.
