    Study Notes

    Development and Reproduction

    • Development refers to the changes an organism undergoes over time.
    • Reproduction involves the formation of new cells or organisms.

    Anatomy

    • Anatomy is the study of the structures of the body, derived from the Greek word meaning to dissect or separate.
    • Two primary approaches:
      • Systemic Anatomy: Studies the body by organ systems.
      • Regional Anatomy: Studies the body by specific areas.

    Ways to Examine Internal Structures

    • Surface Anatomy: Examines external features to locate deeper structures.
    • Anatomical Imaging: Non-invasive techniques for viewing deep structures (e.g., x-rays, CT scans, MRIs).

    Physiology

    • Physiology focuses on the processes and functions of the body, aiming to understand and predict physiological conditions.

    Structural and Functional Organization

    • Organized into levels:
      • Chemical Level: Interactions of atoms forming molecules.
      • Cell Level: Cells are the basic structural and functional units.
      • Tissue Level: Tissues are groups of similar cells.
      • Organ Level: Organs consist of multiple tissue types serving common functions.
      • Organ System Level: Group of organs working together with a specific purpose.
      • Organism Level: The complete living entity.

    Homeostasis

    • Homeostasis maintains stable internal conditions, crucial for survival.
    • Mechanisms include:
      • Negative-feedback: A response that opposes deviation from a set point.
      • Positive-feedback: A rare mechanism where a deviation prompts an increase in activity (e.g., childbirth, blood loss).

    Components for Maintaining Homeostasis

    • Receptors: Detect changes in the environment.
    • Control Center: Analyzes information and determines responses.
    • Effectors: Control mechanisms to adjust variables.

    Body Terminology and Positioning

    • Anatomical Position: Person standing erect with face forward, limbs at sides, and palms facing forward.
    • Body Positions:
      • Supine: Lying face upward.
      • Prone: Lying face downward.

    Directional Terms

    • Inferior: Lower
    • Superior: Higher
    • Anterior: Front
    • Posterior: Back
    • Ventral: Belly
    • Dorsal: Back
    • Proximal: Nearest
    • Distal: Distant
    • Medial: Toward the midline
    • Lateral: Away from the midline
    • Superficial: On the surface
    • Deep: Internal

    Body Parts and Regions

    • Head: Cephalic (includes forehead, eyes, nose).
    • Neck: Cervical.
    • Trunk: Thoracic, abdominal, pelvic regions.
    • Upper Limb: Includes shoulder, arm, forearm, and hand.
    • Lower Limb: Includes thigh, leg, ankle, and foot.

    Abdominal Quadrants

    • Four subdivisions: Right Upper, Left Upper, Right Lower, Left Lower.
    • Epigastric, Umbilical, and Hypogastric regions.

    Characteristics of Life

    • Organization: Interaction among body parts.
    • Metabolism: Energy usage for vital functions.
    • Responsiveness: Sensitivity to environmental changes.
    • Growth: Increase in size.
