Study Notes
Anatomy and Physiology
- Anatomy is the study of the structures of the body.
- Physiology focuses on how those body structures function.
Levels of Structural Organization
- Organization levels include: chemical, cellular, tissues, organs, organ systems, and organism.
Chemical Level
- Represents the most basic level, consisting of atoms of elements.
Cytology
- Cytology is the study of cells.
Tissue Level
- Tissues are formed by similar cells working together to perform a common function.
Types of Tissues
- Epithelial tissue covers body surfaces and lines cavities.
- Connective tissue connects, supports, binds, strengthens, and protects; it is the most abundant type.
- Muscle tissue is responsible for body movement and heat production.
- Nervous tissue processes and transmits information through nerve impulses.
Organ and System Levels
- An organ is formed when multiple tissue types combine for a specific function.
- Organ systems consist of multiple organs working towards a common purpose.
Major Organ Systems
- Integumentary system includes skin, hair, and nails, providing protection and temperature regulation.
- Skeletal system, made up of 206 bones, provides support, structure, and houses blood cell production.
- Muscular system facilitates body movement and generates heat.
- Nervous system processes information from receptors and coordinates responses through impulses.
- Endocrine system regulates body functions via hormone production, influencing growth and metabolism.
- Cardiovascular system circulates oxygen and nutrients throughout the body.
- Lymphatic system helps defend against pathogens.
- Respiratory system brings oxygen into the body and expels carbon dioxide.
- Digestive system processes nutrients and eliminates waste.
- Urinary system filters blood and removes waste.
- Reproductive system is responsible for producing gametes and facilitating reproduction.
Metabolic Processes
- Metabolism encompasses all chemical reactions in the body.
- Anabolic reactions build complex molecules from simpler ones, promoting growth.
- Catabolic reactions break down complex molecules into simpler ones.
Body Functions
- Responsiveness involves reacting to internal and external stimuli.
- Movement includes both external (locomotion) and internal motions (circulation).
- Growth refers to an increase in body size or cell number.
- Reproduction includes cellular replication and sexual reproduction.
- Differentiation is the process where generic cells develop specific functions.
Homeostasis
- Homeostasis is the balance of the internal environment.
- Negative feedback reverses changes back to normal conditions.
- Positive feedback amplifies changes in response to a stimulus.
Pathology
- Pathology involves the study of diseases and disorders, distinguishing between:
- Acute conditions (short-term) and chronic conditions (long-term).
- Local conditions affecting a specific body part vs. systemic conditions affecting the entire body.
- Symptoms reported by patients vs. objective signs observable by a physician.
Anatomical Orientation
- Standard anatomical position features an erect body with feet flat, facing forward, arms at sides, palms forward.
- Terms of direction include anterior (front), posterior (back), lateral (side), superior (above), and inferior (below).
- Proximal refers to being closer, while distal means further away.
- Superficial indicates a position on the surface, and deep refers to being further inside.
Anatomical Planes
- Planes are imaginary flat surfaces that cut through the body:
- Sagittal divides the body into right and left sections.
- Midsagittal divides it equally.
- Frontal (coronal) separates anterior from posterior.
- Horizontal/transverse divides superior from inferior.
- Oblique cuts the body at an angle.
Body Cavities and Membranes
- Abdominopelvic cavity contains abdominal and pelvic organs.
- Dorsal cavity includes the cranial and vertebral cavities.
- Serous membranes, like the visceral pericardium and parietal pericardium, reduce friction and compartmentalize organs.
Imaging Techniques
- X-ray provides black and white images for visualizing bones, distinguishing densities.
- Mammogram specifically checks breast tissue for abnormalities.
- CT scan offers better internal structure visualization through cross-sectional images.
- MRI allows detailed views of soft tissues, tendons, and ligaments.
- PET scan studies body function using radioactive tracers.
- Angiography examines blood flow through arteries.
- Ultrasound utilizes sound waves for imaging without radiation.
