Question

1. The 3-tiered hierarchy of hypothalamus, pituitary, and some gland elsewhere: Endocrine control: What are the Three levels of integration.

2. Contrast the anterior pituitary from the posterior pituitary in terms of hypothalamic neurons, axon lengths, hormone secretion into adenohypohysis vs. directly into blood, the use of hypothalamic releasing hormones (what are they?) or not, the number and type of hormones released by both pituitary glands, the kinds of cells in the adenophypophysis.

3. Describe the functions of secretion and regulation of the 2 posterior pituitary hormones: oxytocin and arginine vasopressin (AVP, antidiuretic hormone (ADH)).

Answer 1

Ans- the three levels of integration will be as follows

1) location of gland- it is the first level of integration because all the glands are located at specific locations in the body.

2) secretion of gland- it is the second level of integration, these glands secrete their individual secretions which are known as hormones.

3) target organ- the hormones secreted by the various glands have their impact on different organs of body which is their third level of integration.
