BIOD 151 Problem Set 1 with
Complete Solutions
Six Levels of Organization - ANS-chemical, cellular, tissue, organ, organ system,
organism
The necessary life function that protects our internal environment from our external
environment is provided by what system? - ANS-Integumentary
The function of movement is provided by what system? - ANS-Muscular
The function of responsiveness is provided by what system? - ANS-Nervous
The function of digestion is provided by what system? - ANS-Digestive
Toward the head end or upper part of a structure (above) is what direction? - ANS-
Superior
Toward or at the front of the body is what direction? - ANS-Ventral
Is the knee proximal or distal to the pelvis? - ANS-Distal
Is the elbow proximal or distal to the hand? - ANS-Proximal
Toward or at the back of the body is what direction? - ANS-Dorsal
Closing of a joint is which action? - ANS-Flexion
Opening of a joint is which action? - ANS-Extension
In anatomical position are the hands in pronation or supination? - ANS-Supination
Why are the hands in this position (answer from #28/above)? - ANS-Because the bones
of the forearm (radius/ulna) are uncrossed in the supinated position
Define elevation and depression: - ANS-Elevation- upward movement of a
structureDepression- downward movement of a structure
Define retraction and protraction: - ANS-Protraction- movement in the anterior direction
Retraction- movement in the posterior direction
