Study Notes
Anatomy and Physiology
- Anatomy focuses on body structure and the names of body parts, while physiology studies the functions of these parts and how they work together.
- The two disciplines are interconnected; the function of a body part is influenced by its structure.
Characteristics of Life
- Cellular structure is fundamental to life.
- Growth and development are key life processes.
- Responsiveness to environmental changes is essential for survival.
- Circulation, respiration, digestion, absorption, excretion, reproduction, and metabolism are critical activities for sustaining life.
Requirements of Organisms
- Water, food, oxygen, heat, and pressure are vital for life processes.
Key Principles of Anatomy and Physiology
- Structure is always related to function.
- The body's primary job is maintaining homeostasis.
Homeostasis
- Homeostasis is the maintenance of a stable internal environment.
- Control systems in the body consist of receptors for stimuli, control centers, and effectors that respond.
Feedback Mechanisms
- Negative Feedback: Most common homeostatic control mechanism; it reduces the intensity of a stimulus (e.g., body temperature regulation).
- Positive Feedback: Less common; amplifies the original stimulus (e.g., blood clotting and childbirth).
Cellular Basis of Activity
- Every function performed by the body starts at the cellular level.
Organization of the Human Body
- The human body is structured into cavities, membranes, and organ systems.
Body Cavities
- Dorsal Cavity: Includes cranial cavity and vertebral canal; contains smaller cavities like oral, nasal, and orbital cavities.
- Ventral Cavity: Comprises thoracic and abdominopelvic cavities, separated by the diaphragm.
Organ Systems
- Integumentary System: Covers the body and regulates temperature.
- Skeletal System: Supports and protects body structures, stores minerals, and facilitates blood formation.
- Muscular System: Enables body movement and maintains posture.
Integration and Coordination
- Nervous System: Processes information and sends signals to muscles and glands.
- Endocrine System: Regulates metabolic functions through hormone secretion.
Transport Systems
- Cardiovascular System: Distributes oxygen and nutrients; removes waste products from cells.
- Lymphatic System: Drains excess fluid and plays a role in immune response.
Absorption and Excretion
- Digestive System: Breaks down food, absorbs nutrients.
- Respiratory System: Facilitates gas exchange in the lungs.
- Urinary System: Removes waste and maintains body fluid balance.
Reproductive System
- Produces new organisms; includes male (testes and associated structures) and female (ovaries and uterus) reproductive systems.
Anatomical Terminology
- Describes body part locations relative to others, assuming the anatomical position (standing, facing forward, arms at sides, palms forward).
Anatomical Terms of Position
- Superior/inferior, anterior/posterior, ventral/dorsal, medial/lateral, distal/proximal, right/left, deep/superficial, caudal/cephalic.
Body Sections
- Sagittal Section: Divides the body into right and left portions.
- Transverse Section: Divides the body into superior and inferior portions, often referred to as a "cross section."
- Coronal Section: Divides the body into anterior and posterior sections.
