    Study Notes

    Sections and Planes of Section

    • A longitudinal section cuts through the long axis of an organ.
    • A transverse section (or cross-section) cuts at a right angle to the long axis.
    • An oblique section is made at an angle other than a right angle.

    Body Cavities

    • The body contains cavities that house internal organs, primarily the dorsal and ventral cavities.
    • Both major cavities are further subdivided into specific regions.

    Serous Membranes

    • Serous membranes line trunk cavities and cover the respective organs, secreting fluid to reduce friction.
    • The parietal membrane lines the cavity wall, while the visceral membrane covers the organs.
    • Examples include:
      • Pericardial cavity surrounds the heart.
      • Pleural cavities surround the lungs.
      • Peritoneal cavity surrounds abdominal and pelvic organs.

    Human Body Study Overview

    • Objectives include defining anatomy, understanding organ systems, and maintaining homeostasis.
    • The course emphasizes participation in discussions and completion of tasks for understanding.

    Body Positions

    • The anatomical position is upright with the head level, eyes forward, arms at sides, and palms facing forward.
    • Prone position: lying face down.
    • Supine position: lying face up.

    Directional Terms

    • Directional terms describe body parts relative to each other, generally in pairs of opposites.

    Body Regions

    • The body can be divided into regions:
      • The trunk consists of the thorax, abdomen, and pelvis.
      • Upper limbs consist of the arm, forearm, wrist, and hand.

    Levels of Organization

    • Six structural levels of organization:
      • Chemical: Interaction of atoms to form molecules.
      • Cell: Basic unit of organisms, containing hereditary information.
      • Tissue: Groups of similar cells (epithelial, connective, muscle, nerve).
      • Organ: Multiple tissue types functioning together (e.g., heart, stomach).
      • Organ System: Groups of organs working together (e.g., urinary system).
      • Organism: A complete living entity, from single cells to complex beings.

    Homeostasis

    • Defined as the maintenance of stable internal conditions, such as temperature.
    • It involves a feedback mechanism with:
      • Receptor: Monitors condition and sends information to control center.
      • Control Center: Compares input to set point and sends output commands to effectors.
      • Effector: Produces a response that alters the controlled condition.
    • Negative feedback restores conditions to set point (e.g., blood pressure).
    • Positive feedback amplifies changes (e.g., childbirth contractions).
