Transcript of Lecture 1, Part 2: Introduction to Anatomical Directions and Orientation

Anatomical Position

• Hands at sides • Palms facing forward• Feet together• Front view (anterior)• Back view (posterior)• Pg. 16 Figure 1-6

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

A. Directional Terminology• Superior (cephalic or cranial) vs. Inferior (caudal)• Anterior (ventral) vs. Posterior (dorsal)• Lateral vs. Medial (mesial)• Proximal vs. Distal• Superficial vs. Deep

Pg. 19 Table 1-3!!!

Superficial vs. Deep

• Superficial – – Toward or at the body

surface

• Deep – – Away from the body

surface

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

Anatomical Planes/Sections

• Sagittal – divides the body into right and left parts–Midline

Anatomical Directions Lab

• Lab report is due in one week!!

• Please follow the protocol given to you and make sure you have drawings or pictures with labels.

• YES…you may use your cell phone to take pictures!!

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

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
