Body Organization notes Flashcards
Gross Anatomy- Regional Approach
shoulder- parts of muscles, nerves, blood vessels, bones, etc
Gross Anatomy- Systems Approach
Skeletal, muscular, urinary, reproductive, cardiovascular, etc
Cell
the smallest structure that performs the characteristics of life
The cell performs the following characteristics of life?
- exchange material with the outside world
- extract energy from molecules- break them down
- synthesize molecules
- replicate
Can a virus perform any characteristics of life? (intracellular parasite)
NO
Dens
tooth
Temporal Bone
temp- time; gray hair around ear shown passage of time
A single cell organism (amoeba) and a multicellular organism (hepatocyte- liver cell) can both do what?
Both perform the functions necessary for life
The Amoeba can only exchange directly with what?
the Amoeba exchanges directly with the EXTERNAL world
The Hepatocyte’s external world is the body’s what?
The Hepatocyte’s EXTERNAL world is the body’s INTERNAL ENVIRONMENT
In addition to performing the characteristic of life, what else does a cell in a multicellular organism do?
A cell in a multicellular organism has to help maintain the internal environment (homeostasis)
Cauda Equina
Horse tail (in the spine)
Arbor Vitae
the tree of life (in brain)
Dens
tooth
Odontoid
tooth like or similar to
Mastoid
breast
Parie
wall
Ectomy
cut away
Inter
between
Intra
inside
Multicellular organisms require systems for Diffusion to take place… Examples
- C.V. and respiratory systems to get oxygen to other cells
- G.I. and C.V. to get nutrients to other cells
- C.V. and respiratory and renal systems to remove metabolic wastes
Will diffusion work in a single cell organism?
Yes; diffusion is slow and can only go short distances
Angina
pain
Chronic
long term
