Summary Introduction

To determine:

The major stimulus for release of parathyroid hormone is

  1. hormonal,

  2. humoral,

  3. neural

Answer to Problem 1MC

Correct answer:

(b) Humoral: The parathyroid hormone is regulated by the rise and fall in the blood calcium level and is a blood-borne chemical.

Explanation for the correct answer:

Option (b) is given as humoral is the major stimulus for release of parathyroid hormone. The release of the hormones in the human blood is stimulated by the different chemical stimuli. These stimuli can be humoral, hormonal, or neural. The humoral stimuli stimulate the release of the hormone in response to changes in the blood concentration or any other body fluid. The change in the composition of various substances stimulates the release of the hormones. The parathyroid gland responds to the changes in the calcium level of the blood. Hence, option (b) is the correct answer.

Explanation of Solution

Explanation for the incorrect answers:

Option (a) is given as hormonal stimuli. The hormonal stimuli stimulate the release of the hormones in response to the release of other hormones. The major stimulus for release of parathyroid hormone is humoral stimuli. Hence, option (a) is the incorrect answer.

Option (c) is given as neural stimuli. The neural stimuli are the nerve signals that stimulate the release of the hormones from the endocrine glands. The major stimulus for release of parathyroid hormone is humoral stimuli. Hence, option (c) is the incorrect answer.

Conclusion

The major stimulus for release of parathyroid hormone is humoral stimuli.
