    Study Notes

    Membranes

    • Mucosa types include nasal cavity, mouth, esophagus, and lung bronchi, each serving specialized functions.

    • Serous membranes line closed body cavities and consist of two layers: the visceral layer covering organs and the parietal layer covering cavity walls.

    • Three main serous membranes:

      • Pleura: Covers lungs and lines pleural cavities.
      • Peritoneum: Lines the abdominal cavity and covers abdominal organs.
      • Pericardium: Surrounds the heart and lines the pericardial cavity.

    • A potential space, or cavity, exists between visceral and parietal layers, allowing for organ movement and reducing friction.

    Cutaneous and Synovial Membranes

    • Cutaneous membrane (skin) is thick, waterproof, and dry; plays a role in regulating bodily functions.

    • Synovial membranes lines joint cavities, producing synovial fluid for lubrication and protecting bone ends.

    Anatomical Terminology

    • Anatomical position: standard reference where the body is upright, feet together, palms facing forward, and face forward.

    Position and Directional Terms

    • Superior: Closer to the head.
    • Inferior: Closer to the feet.
    • Medial: Closer to the midline.
    • Lateral: Further from the midline.
    • Anterior: More in front.
    • Posterior: More in back.
    • Proximal/Distal: Closer to/further from the limb root.
    • Superficial/Deep: Closer to the surface/closer to the interior.
    • Ventral: Towards the front.
    • Dorsal: Towards the back.
    • Prone: Lying face down; Supine: Lying face up.
    • Unilateral: One side; Bilateral: Both sides; Contralateral: Opposite sides.

    Terms of Movement

    • Flexion/Extension: Decreasing/increasing joint angle.
    • Hyperextension: Excessive extension beyond normal limits.
    • Abduction/Adduction: Moving away/towards the midline.
    • Pronation/Supination: Turning palm/foot down/up.
    • Retraction/Protraction: Moving backward/forward.
    • Elevation/Depression: Raising/lowering a part.
    • Rotation/Circumduction: Turning on an axis/circular motion in joints.
    • Inversion/Eversion: Turning the sole of the foot inward/outward.
    • Dorsiflexion/Plantarflexion: Foot movement towards the shin/pointing downwards.
    • Radial/Ulnar Deviation: Wrist movement towards the radius/ulna.
    • Opposition: Movement of the thumb across the palm.

    Characteristics of the Human Body

    • Homeostasis: Maintenance of stable internal conditions.
    • Development: Growth through cell number and size increase.
    • Differentiation: Unspecialized cells becoming specialized.
    • Reproduction: Formation of new individuals.
    • Evolution: Genetic changes in populations over time.

    Levels of Organization

    • Atoms, Molecules, Organelles, Cells, Tissues, Organs, Organ Systems, Organism: Hierarchical structure of biological life.

    Organ Systems Overview

    • Integumentary System: Skin, hair, and nails; protects and regulates temperature.
    • Skeletal System: Bones and ligaments; provides support and protection.
    • Muscular System: Skeletal muscles; enables movement and heat generation.
    • Nervous System: Brain and nerves; processes sensory information and directs responses.
    • Endocrine System: Glands that regulate long-term changes and metabolism.
    • Cardiovascular System: Heart and blood vessels; circulates blood and regulates temperature.
    • Lymphatic System: Spleen and lymph nodes; defends against disease and returns fluid to blood.
    • Respiratory System: Nasal cavities and lungs; facilitates gas exchange.
    • Digestive System: Organs from mouth to intestines; processes food and absorbs nutrients.
    • Urinary System: Kidneys and bladder; excretes waste and regulates water balance.
    • Reproductive System: Specialized organs; responsible for producing offspring.
