Study Notes

Chapter 01 Part A: The Human Body: An Orientation

  • Anatomy is the study of the structure of body parts and their relationship to each other
  • Physiology is the study of the function of body parts, how they work together to sustain life
  • Anatomical terminology allows for accurate communication in health sciences

1.1 Form and Function of Anatomy & Physiology

  • Anatomy studies the structure
  • Physiology studies the function

Topics of Anatomy (1 of 2)

  • Gross or macroscopic anatomy studies large, visible structures
  • Regional anatomy focuses on all structures in a specific area
  • System anatomy focuses on a single system (e.g., cardiovascular)
  • Surface anatomy studies internal structures as they relate to external features

Topics of Anatomy (2 of 2)

  • Microscopic anatomy is the study of structures too small to be seen with the naked eye
  • Cytology focuses on the study of cells
  • Histology studies tissues
  • Developmental anatomy tracks structural and functional changes throughout life
  • Embryology focuses on developments before birth
  • To study anatomy, you need to know terminology and be able to observe, manipulate, palpate, and auscultate body parts

Topics of Physiology

  • Physiology can be broken down by organ systems (e.g., renal, cardiovascular)
  • Often focuses on cellular and molecular levels
  • Looks at how the ability of the body is dependent on chemical reactions occurring within individual cells
  • Those who study physiology need to understand basic physical principles (e.g., electrical currents, pressure, and movement) as well as basic chemical principles

Complementarity of Structure and Function (1 of 2)

  • Anatomy and physiology are closely related
  • Function reflects structure
  • Structure dictates function

Complementarity of Structure and Function (2 of 2)

  • Incisors' sharp edges are ideal for cutting
  • Molars' flat surfaces are ideal for grinding

1.2 Structural Organization

  • Human body is organized from the smallest (chemical) level to the largest (organismal) level
  • Chemical level: atoms, molecules, organelles
  • Cellular level: single cell
  • Tissue level: groups of similar cells
  • Organ level: two or more types of tissues
  • Organ system level: various organs working together
  • Organismal level: all organ systems working together

Levels of Structural Organization (1 of 7)

  • Atoms combine to form molecules
  • Molecules form organelles
  • Cells are made of molecules
  • Tissues are made of similar cells
  • Organs are made of various types of tissues
  • Organ systems consist of various organs that work together closely
  • Organismal level is made of organ systems

Levels of Structural Organization (2 of 7) and so on..

  • Continues in detail the structure of the body

1.3 Requirements for Life

  • Maintenance of life involves: maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, growth

Necessary Life Functions (1 of 5)

  • Maintaining boundaries: plasma membranes & skin
  • Movement: skeletal muscles, cardiac muscle, smooth muscle
  • Contractility refers to movement at the cellular level

Necessary Life Functions (2 of 5) and so on....

  • Continues providing detail and examples for each function

1.4 Homeostasis

  • Homeostasis is the maintenance of relatively stable internal conditions
  • A dynamic state of equilibrium
  • Maintained by all organ systems

Homeostatic Controls (1 of 6)

  • Homeostasis requires constant monitoring and regulation
  • Nervous and endocrine systems play a major role
  • Variables: blood sugar, body temperature, blood volume

Homeostatic Controls (2 of 6) and so on...

  • Detailed description of Receptors, Control Centers, and Effectors in regards to homeostasis.

Homeostatic Controls (4 of 6) and so on....

  • Detailed Description of Positive and Negative Feedback

Body Temperature is Regulated by a Negative Feedback Mechanism ....

  • Body temperature regulation; receptors, effectors, negative feedback

Homeostatic Controls (6 of 6)

  • Positive feedback
  • Examples: labor contractions, blood clotting

Homeostatic Imbalance

  • Disruptions to homeostasis increase risk of disease and aging
  • Less efficient control systems
  • Destructive positive feedback mechanisms may take over,leading to conditions such as heart failure
