Anatomy Overview Quiz

Anatomy

• Anatomy investigates the body's structures, determining shape and size, particularly of bones.
• Derived from a Greek term meaning "to dissect," it focuses on how structure relates to function.
• Levels of anatomy include:
  • Developmental anatomy: Examines structural changes from conception to adulthood, including embryology (first eight weeks).
  • Microscopic anatomy: Studies small structures using microscopes, including:
    • Cytology: Focuses on cell structure and function.
    • Histology: Examines tissues, composed of cells and their surrounding materials.
  • Gross anatomy: Studies structures visible without a microscope; can be systemic or regional.
  • Surface anatomy: Assesses the body's exterior to visualize deeper structures.
  • Anatomical imaging: Utilizes technologies (X-rays, MRI) to visualize internal structures.
  • Anatomical anomalies: Refers to deviations from typical physical characteristics.

Physiology

• Physiology investigates processes and functions of living beings.
• Two major goals include examining responses to stimuli and maintaining stable internal conditions.
• Levels of physiology include:
  • Cell physiology: Studies internal processes within cells, such as energy production.
  • Systemic physiology: Focuses on organ system functions.
• Pathology: The study of disease causes and development, emphasizing structural and functional changes from abnormal conditions.

Structural and Functional Organization

• Chemical level: Based on atoms forming molecules; molecular structure dictates function (e.g., collagen provides skin strength).
• Cell level: Cells are the fundamental units of life; organelles perform specific functions.
  • Nucleus: Houses hereditary information.
  • Mitochondria: Produce ATP for energy.
• Tissue level: Groups of similar cells form tissues, with four basic types:
  • Epithelial
  • Connective
  • Muscle
  • Nervous
• Organ level: Combinations of different tissues create organs, performing specific functions.
• Organ system level: Multiple organs collaborate within an organ system to execute broader physiological functions.
