S14This first chapter is filled with many new words and definitions which you will need to learn to

move forward in this class. You need to know everything in this chapter!

Orientation

Objectives for Chapter 1• Understand levels of organization: molecular/chemical, cellular, tissue, organ, organ system,

organismal• Learn the names, location and function of the 11 organ systems: integumentary, skeletal,

muscular, cardiovascular, nervous, digestive, urinary, endocrine, lymphatic, reproductive and respiratory

• Learn the following terms: anterior/ventral, posterior/dorsal, medial/lateral, superior/rostral or cephalic,inferior/caudal, distal/proximal superficial/deep, visceral/parietal

• Explain the meaning of homeostasis: the continual process of adjusting physiologic processes to maintain a livable environment for the cells.

• Learn what is meant by “the internal environment”: all of the parameters such at temperature, mineral content, organic compound content, pH, etc of the extracellular fluid

• Why is it necessary to have metabolic processes?: metabolism is the sum total of all chemical reactions occurring continuously(anabolism-building, catabolism-breaking down) within cells which define it as being alive. ie: movement, division, utilizing energy etc.

• Understand the planes and sections: sagittal, midsagittal, median, frontal/coronal, transverse/horizontal

• Know the anatomical terms for the common regions of the body• Identify the body cavities and which organs/organ systems are contained within each• Know the imaging techniques used in anatomical and clinical studies• Know the levels of studying anatomy: gross, surface anatomy, microscopic anatomy• Be able to define the borders and content of the mediastinum: laterally-R and L lungs,

superiorly – thoracic inlet, inferiorly – diaphragm, anteriorly – sternum, posteriorly – spinal column. Contents: inferiorly, heart. Superiorly – esophagus, trachea, great vessels of the heart, autonomic nerves and lymphatic vessels.

Know all of these!

median

horizontal

coronalThe plane is different from the “section” of that plane. “section” is one specific “slice” made by a plane (as in the pictures) to look at specific structures

While the external “look” of a human is called bilateral symmetry because if you cut us in half on the median plane, both sides look roughly exact. However, our internal design is called tube within a tube as seen here.

Know all of these and the organs contained in each

Liver, gall bladder, stomach, intestines, spleen, kidneys and pancreas

The body has several linings called serosa or serous linings. These have two layers: the parietal layer is the superficial layer which lies over the visceral layer which is continuous with the surface of the organ which it surrounds. Between the layers is a serous fluid for friction reduction

Learn the 4 quadrant system and which organs lie in each

Learn the “regions”: they are more detailed than quadrants

How we study anatomy

• Histology – study of tissues

• Microscopic – visualization of structures which cannot be seen with the naked eye

• Developmental anatomy – conception to birth

• Cytology – study of cells

Imaging to view internal anatomy

• X-ray – to view bones, tumors and gas• CT – bone, blood vessels and soft tissue. Useful in

trauma.• Angiography – view of blood vessels with use of contrast

dye• PET – positron emission tomography: tracks

radioisotopes to visualize areas of high metabolic activity such as tumors and cancers

• Sonography – use of sonar to image fetuses or organs• MRI – Magnetic resonance imaging. Uses strong

magnetic fields and radio waves producing high-contrast images. Useful to visualize structures surrounded by bone such as nerves and joints.
