Study Notes
Introduction to Anatomy and Physiology - Lecture 1
- This lecture introduces the fundamental concepts of anatomy, physiology, and behavior.
- Learning outcomes include:
- Discussing the relationship between anatomy, physiology, and behavior
- Identifying and explaining levels of structural organization in the human body and their relevance to psychological function
- Reviewing characteristics of life and their psychological relevance
- Explaining homeostasis and its role in maintaining psychological and physical balance
- Reviewing anatomical language
Anatomy, Physiology, and Behavior
- Anatomy: The study of the human body's structure.
- Physiology: The study of the human body's function.
- Behavior: Encompasses all actions and responses of an organism, often influenced by anatomy and physiology.
Levels of Organization
- Subatomic particles (e.g., electrons, protons, neutrons)
- Atoms
- Molecules
- Macromolecules
- Organelles
- Cells
- Tissues
- Organs
- Organ systems
- Organism
Biological Levels and Psychology
- Each level has psychological applications and examples demonstrating its impact.
- Subatomic particles: Basis for understanding neural communication through ionic exchanges (e.g., action potentials).
- Atoms: Basic units of matter forming neurotransmitters, hormones, and molecules essential for brain function (e.g., oxygen for brain metabolism).
- Molecules: Chemical combinations of atoms influence behavior, emotion, and cognition (e.g., dopamine regulates reward and motivation).
- Macromolecules: (e.g., DNA, proteins, RNA) encode genetic information, influencing psychological traits and predispositions (e.g., genetic studies examine links between DNA and psychological disorders).
- Organelles: Specialized structures within cells (e.g., mitochondria) provide energy for neurons to function (e.g., dysfunctional mitochondria linked to neurodegenerative disorders).
Biological Levels and Psychology: Continued
- Cells: Basic functional units of life, with specialized cells (neurons) central to transmitting information in the brain (e.g., studying neural pathways to understand learning and memory).
- Tissues: Groups of similar cells performing specific functions (e.g., nervous tissue, impacting brain function and behavior, such as with traumatic brain injury).
- Organs: Structures composed of tissues (e.g., brain) with specific functions (e.g., the amygdala regulates fear).
- Organ systems: Groups of organs working together to perform complex functions (e.g., the nervous and endocrine systems impacting psychology).
- Organisms: A complete living being (e.g., humans) as a whole, integrating biological processes.
Characteristics of Life and Psychology
- Movement: Integral to motor skills and behavioral responses (e.g., developmental psychology studies infant motor coordination, examining Parkinson's).
- Responsiveness: Central to sensory processing and emotional reactions in response to environmental changes (e.g., cognitive psychology examining decision-making under threat, or anxiety disorders reflecting maladaptive responsiveness).
- Growth: Key in cognitive, emotional, and social development (e.g., Piaget's theory of cognitive development).
- Reproduction: Explored in evolutionary psychology for behaviors linked to mating and parenting (e.g., studies on attachment and mate selection).
- Respiration: Links to stress and relaxation, impacting psychophysiology (e.g., mindfulness techniques reducing anxiety, controlled breathing).
- Digestion: Connected to the gut-brain axis, influencing mood and cognition (e.g., gut microbiota imbalances linked to depression and anxiety).
- Absorption: Critical for brain health (e.g., Vitamin B12 and omega-3 deficiencies impact mental health).
- Circulation: Delivers oxygen and nutrients to the brain impacting cognition and mood (e.g., cardiovascular health potentially improving brain function and reducing depression).
- Assimilation: Analogous to adapting and integrating new information, with practical implications for learning (e.g., Piaget's theory).
- Excretion: Removal of metabolic wastes affecting mental health (e.g., renal issues can lead to cognitive impairments or mood changes).
Homeostasis
- Maintaining a stable internal environment by detecting changes and initiating corrective actions.
- Homeostatic Control Mechanisms involve three parts:
- Receptor: Provides information about the stimuli.
- Control Center: Determines the set point and the appropriate response and sends signals.
- Effector: Initiates responses to restore balance.
Homeostatic Control Mechanisms
- Negative feedback: Prevents sudden, severe changes in the body (e.g., body temperature regulation, blood pressure, glucose).
- Positive feedback: Increases the actions of the body, often short-lived (e.g., blood clotting, childbirth).
Organization of the Human Body
- Different cavities and subdivisions in the body (e.g., cranial, thoracic, abdominal, pelvic cavities).
Body Sections or Planes
- Ways to divide the body for anatomical study (e.g., sagittal, transverse, coronal).
Anatomical Language and Terminology
- Standardized terms for body directions and positions (e.g., superior/inferior, anterior/posterior, medial/lateral).
Lecture Activities
- Concept mapping to visualize interconnections of anatomy, physiology, and psychology.
- Group discussions on homeostasis and its role in psychological well-being (e.g., stress, mental health).
- Case study analysis of real-life examples of homeostasis and the body's response to environmental stressors, highlighting psychological impacts.
