Thermoreceptors in the hypothalamus sense the temperature of the blood. When blood temperature begins to decrease, the hypothalamus releases TRH that stimulates the release of TSH from the anterior pituitary gland. TSH stimulates the thyroid gland to release thyroid hormone (TH). TH stimulates an increase in body temperature, which causes the hypothalamus to decrease release of TRH. Which type of reflex pathway is this thermoregulatory pathway?? Thermoreceptors in the hypothalamus sense the temperature of the blood. When blood temperature begins to decrease, the hypothalamus releases TRH that stimulates the release of TSH from the anterior pituitary gland. TSH stimulates the thyroid gland to release thyroid hormone (TH). TH stimulates an increase in body temperature, which causes the hypothalamus to decrease release of TRH. Which type of reflex pathway is this thermoregulatory pathway?? Simple endocrine reflex Complex neuroendocrine reflex Simple neural reflex Simple neuroendocrine reflex

Hypothalamus is the thermostat of the body as it regulates and maintains body temperature by responding to external signals or stimuli and adjusts the body temperature in a close one to two degree of 98.6 degree.

The regulation involves a different type of endocrine hormones and thyroid gland and receptors that help in signaling the increase or decrease of body temperature it involves neurons and hormones.

Due to the response of thermoreceptors and hormones is known as the neuroendocrine response. Hypothalamus Involves two or more hormones and several steps it known as a complex response.

Thus, the correct answer is a Complex neuroendocrine response.
