Read the following statements :i. endocrine system corrects the imbala...
Statement i: Endocrine system corrects the imbalance originally detected by the nervous system.
Statement ii: Nerve cells and endocrine cells exist side by side in the adrenal gland and pituitary.
Explanation:
Statement i: Endocrine system corrects the imbalance originally detected by the nervous system.
The endocrine system and the nervous system are two major control systems in the body that work together to maintain homeostasis, or a stable internal environment. While the nervous system detects changes in the external and internal environment and initiates quick responses, the endocrine system helps to regulate these responses over a longer period of time.
When the nervous system detects an imbalance or change in the body, it sends signals to the endocrine system to release specific hormones. These hormones are then transported through the bloodstream to target cells or organs, where they initiate a response to correct the imbalance.
Therefore, statement i is correct.
Statement ii: Nerve cells and endocrine cells exist side by side in the adrenal gland and pituitary.
The adrenal gland and pituitary gland are two important organs of the endocrine system.
Adrenal gland: The adrenal gland consists of two main regions: the adrenal cortex and the adrenal medulla. The adrenal cortex is responsible for the production of steroid hormones, such as cortisol and aldosterone, while the adrenal medulla produces catecholamines, such as adrenaline and noradrenaline.
The adrenal medulla is derived from neural crest cells, which are also responsible for the development of nerve cells. Therefore, it can be said that nerve cells and endocrine cells exist side by side in the adrenal medulla.
Pituitary gland: The pituitary gland is often referred to as the "master gland" because it regulates the functions of other endocrine glands in the body. It consists of two main parts: the anterior pituitary and the posterior pituitary.
The posterior pituitary is an extension of the hypothalamus, which is a part of the nervous system. It stores and releases hormones produced by the hypothalamus, such as oxytocin and vasopressin.
Therefore, it can be concluded that nerve cells and endocrine cells exist side by side in the adrenal medulla and the posterior pituitary.
Hence, statement ii is also correct.
Therefore, both statements i and ii are correct.
