A student in an environmental chamber has their core body temperature monitored while cutaneous blood flow is recorded. The diagram below illustrates the two microcirculation patterns observed in their skin:
Which of the following options correctly describes the homeostatic trigger, the muscle states, and the coordinating centre associated with Condition X?
Trigger: Core temperature rises (>37∘C> 37^\circ\text{C}>37∘C)
Arteriole smooth muscle: Relaxed
Shunt vessel smooth muscle: Contracted
Coordinating centre: Hypothalamus
Trigger: Core temperature drops (<37∘C< 37^\circ\text{C}<37∘C)
Arteriole smooth muscle: Contracted
Shunt vessel smooth muscle: Relaxed
Coordinating centre: Hypothalamus
Trigger: Core temperature rises (>37∘C> 37^\circ\text{C}>37∘C)
Arteriole smooth muscle: Contracted
Shunt vessel smooth muscle: Relaxed
Coordinating centre: Medulla oblongata
Trigger: Core temperature drops (<37∘C< 37^\circ\text{C}<37∘C)
Arteriole smooth muscle: Relaxed
Shunt vessel smooth muscle: Contracted
Coordinating centre: Cerebellum
