- The Cellular Level
- The 3rd level of organization for organisms.
- The Tissue Level
- The 4th Level of Organization for an organism.
- The Organ Level
- The 5th level of organization for an organism.
- The organ system level
- The 6th level of organization for an organism
- The Organism Level
- Name the 8 characteristics of life
- Maintaining boundaries, movement, response to stimuli, digestion, metabolism, excretion, growth and reproduction
- Correct Anatomical Position
- body erect, face forward, feet together, palms forward
- Supine Position
- Lying down, face upward
- Prone Position
- lying down, face down
- Superior
- above
- Inferior
- below
- anterior
- front
- posterior
- back
- medial
- toward the midline of the body
- lateral
- toward the extremeties of the body
- proximal
- nearer the point of attachment to the trunk
- distal
- further from the point of attachment at the trunk
- superficial
- on the surface of the body
- deep
- toward the interior of the body
- Name the four quadrants of the trunk region
-
Upper right and left quadrants
Lower right and left quadrants - the region of the trunk that is in the center
- the umbilical region
- the upper left region of the body
- the left hypochondriac region
- the lower left region of the body
- the left iliac region
- the upper right region of the body
- the right hypochondriac region
- the upper center region
- the epigastric region
- the lower center region of the body
- the hypogastric region
- the lower right region of the body
- the right iliac region
- Define the serous membrane
- the membrane that covers the trunk cavities and line them
- Name the serous membrane that lines the actual cavity walls
- the parietal serous membrane
- Name the serous membrane that covers the organs of the trunk cavity
- the visceral serous membrane
- How are serous membranes further named? Give an example.
- Serous membranes are further named for the specific cavity and organs that they cover. An example would be the pericardium, the lining that covers the heart.
- Define homeostasis.
- maintaining balance of interior conditions despite exterior conditions.
- Name the three components of homeostasis.
- The receptor, the control center and the effector.
- Detects a change in conditions and sends a message to the control center.
- The receptor
- Determines the set point for homeostasis.
- The control center
- Makes the decision about what needs to be done to return to the set point.
- The control center
- Carries of the information sent from the control center.
- The effector
- examples of negative feedback mechanism
- body temperature, blood pressure, blood sugar
- examples of positive feedback mechanisms
- child birth, blood clotting
