All of the following are effector responses that increase body temperature, except a : vasodilation of dermal blood vessels b : hormone release from the adrenal medulla c : release of thyroid hormones d : involuntary contraction of skeletal muscle

Option A

Explanation:

The effector response that increases the body is not associated with vasodilation of dermal blood vessels.

The skins's immense blood supply helps in temperature regulation of the body. The dilated blood vessels helps in heat loss and lowers the body temperature.

Unlike, them the vasoconstriction retains heat and increases the body temperature.

So, the correct answer is option A

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
