Anatomy – translated as “a cutting open”◦ Meaning = study of internal and external
structures AND the physical relationship among parts
◦ To summarize: names of parts, location, how they are related
Physiology ◦ Meaning = study of how living organisms perform
their vital functions◦ To summarize: exactly how they do what they do
Anatomy & Physiology - Pg 4

List From Simplest to Most Complex Tell Me Hint to start: smallest stable units of matter,
then smallest unit of life and up
Levels of Biological Organization

Is maintaining a stable internal environment when exposed to harsh external environment
Is way more complex than shivering when cold or sweating when you are hot
Can involve multiple organs and sometimes multiple systems and can spans all biological organization
Sidenote: Do not get bogged down in memorizing this physiology in the text pgs 11-14
Homeostasis

Cranial (Cephalic) Caudal Anterior Posterior (Dorsal) Ventral Superior Inferior
Medial Lateral Proximal Distal Superficial Deep
Anatomical Direction– terms used to describe relative directional positions – location of one part of the body with respect to another part – Table 1-8 pg 19
![Page 8: Slides by Coach Murray Images: Various Sources. Distinguish anatomy and physiology Explain what anatomical position is Recall and contrast basic.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649e915503460f94b966c1/html5/thumbnails/8.jpg)
A “plane” is an axis, you need 3 to describe a 3D object (See Fig 1-9)
To observe internal structures we refer to these three different planes or “slices” through the body (pg 20)◦ 1. Sagittal◦ 2. Transverse◦ 3. Frontal (or coronal)
Sectional Body Planes – Pg 19-20
![Page 9: Slides by Coach Murray Images: Various Sources. Distinguish anatomy and physiology Explain what anatomical position is Recall and contrast basic.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649e915503460f94b966c1/html5/thumbnails/9.jpg)
Review Table 1-4 pg 20 Write yourself a detailed description for each of the 3 planes◦ 1. Sagittal◦ 2. Transverse◦ 3. Frontal (or coronal)
Sectional Body Planes – Pg 19-20
![Page 10: Slides by Coach Murray Images: Various Sources. Distinguish anatomy and physiology Explain what anatomical position is Recall and contrast basic.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649e915503460f94b966c1/html5/thumbnails/10.jpg)
Body Planes – name that plane

Are Internal chambers that house organs
Protect from shock/bumps
Allow organs to change size
2 “major cavities”◦ Dorsal and Ventral◦ House all others
“Major” Body Cavities – pg 21
![Page 12: Slides by Coach Murray Images: Various Sources. Distinguish anatomy and physiology Explain what anatomical position is Recall and contrast basic.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649e915503460f94b966c1/html5/thumbnails/12.jpg)
Within the Dorsal Cavity◦ Cranial and Spinal◦ Are 2 separate cavities
Body Cavities – Fig 1-10 pg 21
![Page 13: Slides by Coach Murray Images: Various Sources. Distinguish anatomy and physiology Explain what anatomical position is Recall and contrast basic.](https://reader035.fdocuments.us/reader035/viewer/2022062802/56649e915503460f94b966c1/html5/thumbnails/13.jpg)
Within the Ventral Cavity1. Thoracic Cavity (chest)
Pleural cavities (2) – L& R: 1 cavity for each lung Mediastinum – contains pericardial – supports
esophagus, trachea, thymus, heart blood vessels Pericardial cavity – contains heart
2. Abdominopelvic Cavity (diaphragm to pelvis) Abdominal cavity – liver, stomach, spleen, small
intestine, most of large intestine Pelvic cavity – reproductive, bladder, distal large
intestine Peritoneal cavity
Parietal peritoneum Visceral peritoneum
Body Cavities – Fig 1-10 and pg 21-22
