#Question id: 24173

The Greek ideal of the hero most closely resembles today’s freeagent superstar.

#Aptitude
  1. A superstar is an athlete who commands a great salary based on his individual skills.
  2. The Greek warrior’s focus was on grasping at immortality, and he did this by ensuring that his name would live on, long after he died.
  3. The Greek hero valued self-interest above loyalty to a cause, his king, or to his army, just as the free-agent superstar values his contract salary above any special team, coach, or the game.
  4. The Greek hero was impressive in his performance on the battlefield as well as in the sports arena.

#7. System Physiology – Animal

Following statements are regarding to the heat production by the activation of sympathetic nervous system.
A. Activation is stimulation of β receptors in brown fat, which increases metabolic rate and heat production.
B. Activation is stimulation of α2 receptors in brown fat, which increases metabolic rate and heat production.
C. Stimulation of α1 receptors in vascular smooth muscle of skin blood vessels, producing vasoconstriction. Vasoconstriction reduces blood flow to the surface of the skin.
D. Stimulation of α1 receptors in vascular smooth muscle of skin blood vessels, producing vasodilation. Vasodilation reduces blood flow to the surface of the skin.

#7. System Physiology – Animal

Following statements are regarding to Shivering, which is the most potent mechanism for increasing heat production in the body. 
A. Cold environmental temperatures activate centers in the posterior hypothalamus during shivering, which then activate the α and γ motoneurons innervating skeletal muscle. 
B. Shivering involves skeletal muscle contracts rhythmically, generating heat and raising body temperature.
C. Shivering involves stimulation of Na+-K+ ATPase and raising body temperature.
D. Shivering involves stimulation of β receptors in brown fat, which increases metabolic rate and heat production.

#7. System Physiology – Animal

Following statements are regarding to the regulation of body temperature.
A. The temperature-regulating center is located in the anterior hypothalamus. This center receives information about environmental temperature from thermoreceptors in the skin and about core temperature from thermoreceptors in the anterior hypothalamus itself.
B. The temperature-regulating center is located in the posterior hypothalamus. This center receives information about environmental temperature from thermoreceptors in the posterior hypothalamus itself and about core temperature from thermoreceptors in the skin.
C. If core temperature is below the set-point temperature, then heat-generating and heat-retaining mechanisms are activated.
D. If core temperature is above the set-point temperature, then heat-dissipating mechanisms are activated.
E. If core temperature is below the set-point temperature, then heat-dissipating mechanisms are activated.
F. If core temperature is above the set-point temperature, then heat-generating and heat-retaining mechanisms are activated.

#7. System Physiology – Animal

Fever is an abnormal elevation of body temperature. Following statements are regarding to the cellular mechanism of fever.
A. Pyrogens produce fever by increasing the hypothalamic set-point temperature.
B. the mechanism of pyrogen action is increased production of interleukin-1 (IL-1) in phagocytic cells.
C. IL-1 then acts on the anterior hypothalamus to increase local production of prostaglandins, which increase the set-point temperature.
D. IL-1 then acts on the posterior hypothalamus to increase local production of prostaglandins, which increase the set-point temperature.
E. IL-1 then acts on the posterior hypothalamus to increase local production of prostaglandins, which decrease the set-point temperature.
