When you go to a massage therapist, know that you’re meeting with someone who has studied and studied hard. The following are the notes of things we will need to know for a test on this coming Tuesday. This information comes from our lecture and from the Susan Salvo book Massage Therapy Principles and Practice. If you’re studying massage or want to, this will be great information for you. If you’re not, this may not be the most exciting reading, but it’s informative.
Chapter 18 Notes:
1. Anatomy – The study of the structures of the human body and their positional relationship to one another.
2. Physiology – the study of how the body and its individual parts function in normal body processes.
Levels of Organization pg. 385
Chemical Level – Biochemistry of body
Cellular – basic unit of life
Tissue – Groups of cells that share a similar structure and function
Organ – Complex structures of two or more tissue types performing a specific function.
Organ system- Related organs with complementary functions that perform certain tasks.
Organism – Living entities composed of several organ systems (Most complex level.
Study of the cell:
Remember that the control center is the Nucleus. The cell membrane is like its skin and separates cytoplasm from the surrounding external environment. It is semipermeable, letting some things in and keeping others out.
Cytoplasm is like jello inside the cell. It’s made primarily of water and all of the organelles float in it. Then there’s my favorite. It’s the Endoplasmic reticulum. That’s the transportation system of the cell. It “functions in the synthesis of protein and lipids” and transports them to where they need to go. Inside the Endoplasmic Reticulum you might find ribosomes. What they do is synthesize protein to be used in the cell. The packing and shipping plants of the cell are called Golgi bodies. They are “a series of four to six horizontal membranous sacs that alter the lipids and proteins” and store them for later. Next we have the Mitochondria, the power plant. This is where cellular respiration happens and the Adrenosine triphosphate is made. The last one we are responsible for knowing is the Lysosomes. They “engulf the pathogens, cellular debris and other organelles” pg. 387. They are the garbage collectors. They clean up and get rid of things we no longer need….like excess uterus after childbirth.
Cell Physiology –
Diffusion – Movement of molecules from an area of high concentration to an area of low concentration. pg. 388
Filtration – Movement of particles across the cell membrane because of pressure pg. 388
Osmosis – Osmosis moves water, in and out of a cell.
Active transport – This occurs when something needs a little help getting through. Ions, Amino acids and sugars are moved in or out despite pressure levels.
Next we have phagocytosis and pinocytosis – Remember phagocytosis happens when certain cells EAT harmful things and then expel the harmless debris back into the body. Pinocytosis is the same thing except these guys drink harmful liquids.
The next section of this chapter will be in the next article. Study hard!!
