The group getting the sugar pill is the control group The nose is superior to the mouth True If the effects of a drug are being tested by a scientific experiment, two groups would be used: a group that gets the drug and a group that gets an inactive substance. The group that gets the inactive substance is called the control group True The mouth is inferior to the chin False Because humans walk upright, dorsal and posterior mean the same thing True The single method used for all scientific investigation is called the scientific method False The two major cavities of the body are the abdominal and thoracic cavities False A cut dividing the body into right and left portions is called a sagittal section A body in a supine position has its dorsal side to the ground True The epigastric, umbilical, and left lumbar regions are all in the middle abdominopelvic area False The term most opposite medial is lateral The lower abdominopelvic regions include the right and left iliac and hypogastric The smallest living unit of structure is considered to be at the cellular level The brain is in the cranial cavity Anterior and proximal are opposite terms False The hand is distal to the elbow True The bones of the arm are superficial to the muscles of the arm False When reading a compass rosette in a figure, the letter P opposite the letter D stands for posterior False The mediastinum is in both the ventral and thoracic cavities True The sensor in a feedback loop compares the actual condition to the "normal" condition the body tries to maintain False The heart is an example of this level or organization Organ Using the maintaining of a constant temperature in a building as an example of a feedback loop, the thermometer would be an example of a(n) sensor The reference position for all body directional terms is the anatomical position In the negative feedback loop, the effector is the link between the sensor and the control center False A scientific experiment testing a new drug used two groups, one getting the drug and one getting a sugar pill.
