3Overview of Anatomy and Physiology
- Anatomy Scientific discipline that investigates
the bodys structure - Physiology Scientific investigation of the
processes or functions of living things
4Topics of Anatomy
- Gross or macroscopic Structures examined
without a microscope - Regional Studied area by area
- Systemic Studied system by system
- Surface External form and relation to deeper
structures as x-ray in anatomic imaging - Microscopic Structures seen with the microscope
- Cytology Cellular anatomy
- Histology Study of tissues
5Topics of Physiology
- Reveals dynamic nature of living things
- Consider operations of specific organ systems
- Cell physiology Examines processes in cells
- Neurophysiology Focuses on the nervous system
6Structural Functional Organizations
- Chemical level
- Atoms
- Molecules
- Cellular Level
- Tissue Level
- Organ Level
- Organ System Level
7Structural Functional Organizations
8Organ Systems of the Body
9Organ Systems of the Body
10Organ Systems of the Body
11Organ Systems of the Body
12Characteristics of Life
- Organization Condition in which there are
specific relationships and functions - Metabolism All chemical reactions of the body
- Responsiveness Ability to sense changes and
adjust - Growth
- Development Changes over time
- Differentiation Change from general to specific
- Reproduction New cells versus organisms
13Feedback
- Positive Feedback When a deviation occurs,
response is to make deviation greater - Leads away from homeostasis
- Can result in death
14Terminology and Body Plan
- Anatomical Position
- Body erect, face forward, feet together, palms
face forward - Other Body Positions
- Supine lying face upward
- Prone lying face downward
- Directional Terms
- Superior versus Inferior
- Anterior versus Posterior
- Medial versus Lateral
- Proximal versus Distal
- Superficial versus Deep
15Body Parts and Regions
16Body Parts and Regions
17Abdominal Subdivisions
18Body Planes
- Sagittal / Midsagittal / Median
- Frontal or Coronal
- Transverse / Cross
- Oblique Other than at a right angle
19Body Cavities
20Serous Membranes
- Cover the organs of trunk cavities line them
- Parietal lines cavity walls
- Visceral covers organs
- Serous fluid secreted for lubrication by
membranes - Named for their specific cavity organs
- Pericardium refers to heart
- Pleura refers to lungs and thoracic cavity
- Peritoneum refers to abdominopelvic cavity
- Inflammation of the serous membranes

23Medical Imaging - Clinical Focus
- X-Ray or radiograph is shadowy negative of
internal body structures - CT or computed tomography is refined version of
an x-ray and slices body - DSR or dynamic spatial reconstruction is three
dimensional imaging and allows movement - Sonography or ultrasound is inexpensive and safer
than ionizing radiation - MRI or magnetic resonance imaging produces
high-contrast imaging of soft tissues
