Anatomy Basics
- Anatomy is the study of bodily structures, crucial for understanding human physiology.
- Gross anatomy focuses on larger body structures, such as the brain, while microscopic anatomy examines structures only visible through microscopes.
Anatomical Specializations
- Regional anatomy studies interrelationships of structures within specific body regions, such as the abdomen.
- Systemic anatomy studies structures of specific body systems, like the nervous system.
Cell and Tissue Structures
- The cell is the smallest independently functioning unit of life.
- Organelles are tiny units within cells that perform specific tasks.
- Tissues are groups of similar cells working together for specific functions.
- Organs are distinct anatomical structures comprised of multiple types of tissues, fulfilling various physiological functions.
- An organ system consists of groups of organs collaborating to meet the body's physiological needs.
Homeostasis and Life Processes
- Homeostasis is the maintenance of stable internal conditions.
- Metabolism is the total of all chemical reactions, including anabolism (building complex molecules, which consumes energy) and catabolism (breaking down molecules, which releases energy).
- Responsiveness is an organism's ability to adjust to environmental changes.
Developmental Processes
- Development encompasses the changes an organism undergoes, including differentiation (unspecialized cells becoming specialized), growth (increase in size), and reproduction (formation of new organisms).
Requirements for Life
- Essential requirements include oxygen, nutrients (water, macronutrients, micronutrients), specific temperature ranges (around 37°C or 98.6°F), and atmospheric pressure.
Homeostatic Mechanisms
- Sweating cools the body through evaporation, while shivering generates heat through muscle activity.
- Negative feedback mechanisms maintain homeostasis, involving sensors, control centers, and effectors to regulate physiological values around set points.
Anatomical Position and Terminology
- The anatomical position refers to an upright body stance with feet parallel and toes forward.
- Directional terms include anterior (front), posterior (back), superior (above), inferior (below), lateral (side), medial (middle), proximal (closer to point of attachment), and distal (farther from point of attachment).
Anatomical Planes and Cavities
- Planes include sagittal (divides right and left), midsagittal (equal halves), parasagittal (unequal sides), frontal (anterior and posterior), and transverse (superior and inferior).
- Cavities:
- The dorsal cavity houses the brain and spinal cord.
- The ventral cavity includes the thoracic and abdominopelvic cavities, containing vital organs like the heart, lungs, and digestive organs.
- Serous membranes, such as the pleura (lungs) and pericardium (heart), reduce friction around organs.
Imaging Techniques
- X-rays utilize high-energy radiation to visualize structures, especially bones.
- CT scans provide detailed cross-sectional images using multiple X-rays analyzed by computers.
- MRI creates detailed images through magnetic fields and radio waves.
- PET scans trace radiopharmaceuticals to observe metabolic activities.
- Ultrasonography employs ultrasonic waves to visualize body structures non-invasively.
Cellular Renewal and Repair
- Renewal is the process of replacing worn-out cells to maintain optimal body function.
