Module 1: Organization of the Human Body Flashcards
Anatomy
science of body structures and the relationships among them
dissection
careful cutting apart of body structures to study
Physiology
the science of body functions
Embryology
first 8 weeks of development after fertilization of a human egg
Developmental biology
complete development of an individual from fertilization to death
Cell biology
Cellular structure and function
Histology
study of microscopic structure of tissues
Gross anatomy
Structures that can be examined without a microscope
Systemic anatomy
Structure of specific systems of the body
ex. nervous, respiratory system
Regional anatomy
Specific regions of the body such as the head or chest
Surface anatomy
Surface markings of the body to understand internal anatomy through visualization and palpation
Pathological anatomy
Structural changes (gross to microscopic) associated with disease
Neurophysiology
Functional properties of nerve cells
Endocrinology
Hormones and how they control body functions
Cardiovascular physiology
Functions of the heart and blood vessels
Immunology
The body defences against disease-causing agents
Respiratory physiology
Functions of the air passageways and lungs
Renal physiology
Functions of the kidneys
Exercise physiology
changes in cell and organ functions due to muscular activity
Pathophysiology
Functional changes associated with disease and aging
Levels of structural organization (Small-high)
Chemical Cellular Tissue Organ System Organismal
Chemical level (simplest)
Interactions and combinations of atoms
Cellular Level
Combinations of molecules forming cells
Tissue Level
Similar cells working together to perform a similar function
Organ Level
Several types of tissue that work together to perform a similar function
System Level
Several organs that each have a specific function int he overall activity of a body system
Organismal Level (highest)
All the body systems
11 Major systems
Integumentary Skeletal Muscular Nervous Endocrine Cardiovascular Lymphatic/immune Digestive Respiratory Urinary Reproductive
Integumentary System
Skin, accessory organs (hair, nails, sweat glands)
Regulates body temp
Skeletal System
Bones of the skeleton and associated cartilage
Protects/supports organs, forms blood cells, stores minerals
Muscular System
Skeletal muscle, smooth muscle, and cardiac muscle
Produces movement, body heat
Nervous System
Brain, spinal cord, and associated nerves
Coordinates body actives through rapid activation of muscles and glands
Endocrine System
Ductless Grands that secrete hormones
Regulates metabolism and chemical reactions
