Ch 1: Introduction to Anatomy Chapter Objectives Define study of Anatomy Identify the levels of organization Understand anatomical and directional terminology to be used during course Review body cavities and lining membranes Immerse yourself into the language of Anatomy

Anatomy (= to cut open) Gross Anatomy Microscopic Anatomy Developmental Anatomy (study of first 2 months of development: _?_) Comparative Anatomy

Gross Anatomy Surface Anatomy (Ch 12) Regional Anatomy (superficial and internal features in specific area of body, e.g. head and neck....) Systemic Anatomy (11 organ systems)

11 Organ systems different organs work together to provide specialized functions Body Coverings Support & Movement Integration & coordination Transport Absorption / Excretion Reproduction

Cytology (mostly EM pictures) Histology Microscopic Anatomy Cytology (mostly EM pictures) Histology SEM TEM

Anatomy at Different Scales (Metric Scale) Fig 1.1

Levels of Organization: See figs. 1.3 & 1.4 COHN – 99.5% 99.9% =

Anatomy & the Importance of a Precise Vocabulary Language of Anatomy based mostly on . . . ? Also Eponyms (= ?)

Superficial Anatomy Generally consider body in Anatomical Position while studied Two other positions: supine and prone Anatomical Directions Anterior vs. ?; medial vs. ?; superior vs. ? . . . Etc. . . . Proximal vs. distal

Anatomical Regions: Take words apart!

In the clinic: Abdomino-pelvic Regions

Sectional Anatomy 3 sectional planes: transverse ( or cross) section frontal (or coronal) section sagittal section (mid- and para-)

Fig 1.14 Body Cavities Dorsal Ventral

Clinical Discussion: Sectional Anatomy and Clinical Technology Avoid “cutting open” Computers integrate raw data transmitted by electrical signals Radiological procedures: X-rays CT MRI

Traditional: X-rays X-ray of skull Radiodensity of different tissues Since 1895 X-ray of skull Radiodensity of different tissues Varies: Denser tissues absorb more radiation Disadvantage? Best for bones and some tumors and tuberculosis nodules in lungs

X-rays and Contrast Medium Use of heavy elements such as _______, iodinated molecules etc.etc. Barium sulphate (BaSO4) insoluble

Clinical Discussion: The visible Human Produce series of sections in one sectional plane at small intervals Combine to reconstruct the 3-D object (serial reconstruction) Allows for very exact analysis of complex structures Male sectioned at 1 mm intervals, female at 0.33 mm intervals.
