Study Notes
Introduction to Anatomy and Physiology
- Anatomy is a subdivision of biology focusing on the structure and relationships of body parts.
- The term 'anatomy' derives from Greek: "ana" (apart) and "tomy" (to cut).
- Physiology studies the functions of body parts and how they operate.
- 'Physiology' comes from Greek: "physio" (nature) and "ology" (the study of).
Relationship between Anatomy & Physiology
- Body parts collaborate as a well-organized unit; each has specific functions for overall operation.
Levels of Study in Anatomy
- Gross Anatomy deals with large structures observable without a microscope.
- Microscopic Anatomy studies tiny structures only visible through microscopy.
Structural Organization
- Hierarchical organization includes: Cell → Tissue → Organ → Organ System.
Overview of Organ Systems
- Integumentary System: Consists of skin, hair, nails, and glands; protects organs, excretes waste, and regulates temperature.
- Skeletal System: Comprised of bones, cartilages, and ligaments; supports and protects organs, provides leverage for movement, stores minerals, and forms blood cells.
- Muscular System: Muscles attached to skeleton; responsible for movement and heat generation.
- Nervous System: Includes brain and nerves; transmits messages and detects environmental changes.
- Endocrine System: Comprises glands like the pituitary and thyroid; produces hormones that regulate growth and long-term homeostasis.
- Cardiovascular System: Consists of heart and blood vessels; transports blood and offers protection.
- Lymphatic/Immune System: Includes lymphatic vessels and nodes; cleanses blood and returns fluids to the circulatory system.
- Respiratory System: Comprising lungs and airways; supplies oxygen and removes carbon dioxide.
- Digestive System: Includes gastrointestinal tract; breaks down food for absorption.
- Urinary System: Composed of kidneys and bladder; maintains fluid and electrolyte balance.
- Reproductive System: Involves organs for producing and fertilizing gametes.
Homeostasis
- Represents a dynamic balance of internal conditions within narrow limits.
- Key components: Receptors (respond to stimuli), Control centers (analyze information), Effectors (elicit responses).
Feedback Mechanisms
- Two types: Negative feedback (counteracts change) and Positive feedback (amplifies change).
Anatomical Position and Body Orientation
- Anatomical Position: Standing upright with arms at sides, palms forward; serves as a reference point.
- Directions: Superior (above), Inferior (below), Anterior (front), Posterior (back), Medial (towards midline), Lateral (away), Proximal (near trunk), Distal (far from trunk), Superficial (near surface), Deep (far from surface).
Body Landmarks
- Anterior Landmarks: Include abdominal (tummy), cervical (neck), patellar (knee cap), etc.
- Posterior Landmarks: Include gluteal (buttocks), lumbar (lower back), occipital (base of skull), etc.
Body Planes and Sections
- Sagittal/Midsagittal Plane (divides left and right), Frontal/Coronal Plane (divides front and back), Transverse/Cross Section Plane (divides top and bottom).
Body Cavities
- Dorsal Cavity: Contains cranial cavity (brain) and spinal cavity (spinal cord).
- Ventral Cavity: Contains thoracic cavity (heart, lungs), abdominal cavity (abdomen), and pelvic cavity (reproductive organs).
Abdominopelvic Quadrants
- Divided into upper and lower quadrants for localization of organs.
Abdominopelvic Regions
- Major regions: Right and Left Hypochondriac, Epigastric, Right and Left Lumbar, Umbilical, Right and Left Iliac.
Body Membranes
-
Epithelial Tissue Membrane: Includes cutaneous (skin), mucous (lining of cavities), and serous membranes (line body cavities).
- Parietal Layer: Lines walls of cavities.
- Visceral Layer: Covers organs within cavities.
