Study Notes
Body Planes and Divisions
- The midsagittal plane divides the body into two equal left and right halves.
- A horizontal or transverse plane separates the body into superior (upper) and inferior (lower) portions, not left and right.
- A sagittal plane is any vertical plane parallel to the midsagittal plane, dividing the body into unequal right and left portions.
Anatomical Terminology
- Viscera refers to the organs located within a body cavity.
- The term parietal describes the walls that enclose a cavity.
Body Cavities
- The ventral cavity is associated with organs that help maintain homeostasis, not specifically the nervous system.
Body Organization
- Tissues are the fundamental building blocks that organize to form organs, not the other way around.
- Cells are responsible for all necessary life activities, including excretion.
Muscle Tissue
- Muscle fibers are elongated cells found in muscle tissue.
- Cardiac muscle is unique to the heart.
Important Physiological Processes
- The pleural membrane covers the lungs.
- The liver converts toxic ammonia to urea, a non-toxic waste product.
- ATP serves as the high-energy molecule required for cellular functions.
- Water is the universal solvent, facilitating most chemical reactions in the body.
Nutritional Components
- Chloride (Cl-) is crucial for nervous transmission rather than muscle contraction or bone strength.
- The primary role of carbohydrates is energy storage, with additional functions in cell reinforcement.
Enzymatic Functions
- Enzymes are proteins that act as catalysts, enhancing the rate of chemical reactions without being consumed in the process.
- The plasma membrane of cells is selectively permeable, controlling the passage of substances in and out of the cell.
