Explanation:
6. Reflex action is a quick, automatic response to the change in environment (stimulus) that involves only spinal cord which is central nervous system.(the complex of nerve tissues that controls the activities of the body. )The reflex actions are controlled both by brain and spinal cord.
7. Every other cell depends on the thyroid to manage its metabolism. The pituitary gland and hypothalamus both control the thyroid. When thyroid hormone levels drop too low, the hypothalamus secretes TSH Releasing Hormone (TRH), which alerts the pituitary to produce thyroid stimulating hormone (TSH).
8. Glucagon is released by the pancreas in response to low blood glucose levels and stimulates the breakdown of glycogen into glucose, which can be used by the body. The body's basal metabolic rate is controlled by the thyroid hormones thyroxine (T4) and triiodothyronine (T3).
9. The anterior pituitary gland produces the following hormones and releases them into the bloodstream: adrenocorticotropic hormone, which stimulates the adrenal glands to secrete steroid hormones, principally cortisol. growth hormone, which regulates growth, metabolism and body composition.
10. Most people say that the pancreas is the only gland that is both endocrine and exocrine.
