Explain the difference between endocrine and exocrine glands, and provide an example of each type of gland.
Explain the difference between endocrine and exocrine glands, and provide an example of each type of gland.
Endocrine glands release hormones internally and are ductless, while exocrine glands release nonhormonal substances externally through ducts. An example of an endocrine gland is the thyroid gland, and an example of an exocrine gland is the sweat gland.
What are the 3 types of stimuli that trigger endocrine glands to make and release hormones? Provide an example of each type of stimulus.
What are the 3 types of stimuli that trigger endocrine glands to make and release hormones? Provide an example of each type of stimulus.
The 3 types of stimuli are humoral stimuli, neural stimuli, and hormonal stimuli. An example of humoral stimuli is low calcium levels in the blood triggering the parathyroid glands to release parathyroid hormone (PTH). An example of neural stimuli is the release of hormones caused by neural input.
Explain how negative feedback mechanisms control the synthesis and release of hormones.
Explain how negative feedback mechanisms control the synthesis and release of hormones.
Negative feedback mechanisms involve the target/effector organ's response feeding back to inhibit further hormone production. When hormone levels reach a certain point, the response of the target organ inhibits the further production of that hormone.
