Study Notes

General Overview

Anatomy is the study of the structure of living organisms and their parts.
It encompasses gross anatomy (visible structures) and microscopic anatomy (structures needing magnification, like cells and tissues).
It provides a foundation for understanding physiology (body function).
Knowledge of anatomy is crucial for medical and biological fields, enabling accurate diagnoses and treatments.

Branches of Anatomy

Gross Anatomy: Examines large, visible structures, including organ shape and systems. Approaches include regional anatomy (body areas), systemic anatomy (organ systems), and surface anatomy (surface landmarks).
Microscopic Anatomy: Focuses on structures needing magnification – cells and tissues. Subdivisions include:
- Cytology: Study of cells.
- Histology: Study of tissues.
Developmental Anatomy: Examines structural changes through an organism's life cycle, from conception to maturity.
Comparative Anatomy: Compares structures across species to understand evolutionary relationships and adaptations.
Pathological Anatomy: Studies anatomical changes related to disease.

Anatomical Terms and Directional Terminology

Directional Terms: Describe locations in relation to each other. Examples: superior/inferior, anterior/posterior, medial/lateral, proximal/distal, superficial/deep.
Planes of Sectioning: Anatomical sections along specific planes: sagittal (left/right), frontal (anterior/posterior), transverse (superior/inferior).
Body Cavities: Internal spaces protecting and housing organs. Main cavities include dorsal (cranial and spinal) and ventral (thoracic and abdominopelvic).

Anatomical Landmarks

Anatomical Position: Standardized reference: standing erect, facing forward, arms at sides, palms forward, feet apart.
Surface Landmarks: Physical features on the body used to locate deeper structures (bony prominences, muscle attachments).
Reference Points: Starting points for describing structure locations (e.g., navel for kidney position).

Major Organ Systems

Integumentary System: Skin, hair, nails, and glands. Protects, regulates temperature, and synthesizes vitamin D.
Skeletal System: Bones, cartilages, and ligaments. Supports, protects, provides movement, and forms blood cells.
Muscular System: Skeletal, smooth, and cardiac muscles. Responsible for movement, posture, and heat production.
Nervous System: Brain, spinal cord, nerves, and sensory organs. Regulates body functions via electrochemical signals.
Endocrine System: Glands secreting hormones. Regulates metabolism, growth, and reproduction.
Cardiovascular System: Heart, blood vessels (arteries, veins, capillaries), and blood. Circulates blood, delivering oxygen and nutrients, removing waste.
Lymphatic and Immune System: Lymph nodes, vessels, and lymphoid organs. Crucial for immunity.
Respiratory System: Lungs, trachea, bronchi. Enables gas exchange (oxygen and carbon dioxide).
Digestive System: Mouth, esophagus, stomach, intestines, and associated organs. Breaks down food, absorbs nutrients, and eliminates waste.
Urinary System: Kidneys, ureters, bladder, urethra. Filters blood, regulates water/electrolyte balance, and removes waste.
Reproductive System: Organs for reproduction (testes, ovaries, etc.).

Basic Tissue Types

Epithelial Tissue: Covers surfaces, lines cavities, and forms glands. Functions in protection, secretion, absorption, filtration, and excretion.
Connective Tissue: Supports, connects, and separates tissues. Includes bone, cartilage, tendons, ligaments, adipose tissue, and blood.
Muscle Tissue: Contracts for movement (skeletal, smooth, cardiac).
Nervous Tissue: Conducts nerve impulses; composed of neurons and supporting cells.

Studying Methods

Dissection: Carefully cutting and separating tissues to visualize structures.
Imaging Techniques: Non-surgical ways to visualize internal anatomy (X-rays, CT scans, MRIs, ultrasounds, endoscopy).
Histology: Microscopic study of tissues.
Radiography: Imaging using ionizing radiation (X-rays).
