Anatomical Position – Supine vs. Prone
• Supine – – Lying with the front or face and hands facing upward
• Prone – – Lying with the front or face and hands facing downward

Anatomical Planes/Sections• Frontal (coronal) –
divides the body into anterior/posterior parts
• Transverse (horizontal) – divides the body into superior/inferior parts– Also known as a
cross-section

Major Body Cavities & Structures• Cavity – hollow area within the body• Two Major Cavities:
Dorsal• Cranial Cavity – pg. 207• Vertebral Cavity – pg. 224
Ventral: houses a group of internal organs (viscera); subdivided into:• Thoracic Cavity – ribs and
chest• Abdominal Cavity –
directly below the diaphragm
• Pelvic Cavity – below Abdominal Cavity

D. Clinical Terminology
• Read “Sectional Anatomy and Clinical Technology” pgs. 12-14 in A & P Applications Manual.
• Radiography –– Film records (radiographs) of internal
structures of the body made by electromagnetic radiation (X-rays, gamma rays, radio waves) passing through the body to act on special film
– CT/CAT (computerized axial tomography) –
• Imaging technique that uses X-rays to reconstruct the body’s 3-D structure
CT/CAT scanning machine
![Page 21: Lecture 1, Part 2: Introduction to Anatomical Directions and Orientation](https://reader035.vdocuments.us/reader035/viewer/2022081516/56813942550346895da0dbf2/html5/thumbnails/21.jpg)
D. Clinical Terminology– PET (position emission
tomography) –• Imaging technique that shows the
chemical functioning and structure of organs
– MRI (magnetic resonance imaging) –
• Imaging technique that uses a magnetic field and radio waves to show subtle structure differences
– Ultrasound – • Imaging technique that uses brief
bursts of high-frequency sound waves reflected by internal structures
