In this article we will discuss about the functions of ionic calcium. i. Maintenance of RMP: Because of this, the excitability of neuron and muscle is maintained. A decrease in calcium ion level increases the excitability and vice versa when calcium ion level decreases. ii. N-M transmission: It plays an important role in conduction of impulse across neuromuscular junction. The [...]
In this article we will discuss about the role of hormones in glucose homeostasis. Glucose homeostasis is brought about by: a. Actions of hormones on metabolism and glucostatic role of b. Hypothalamus c. Liver Actions of Hormones on Metabolism: Many of the hormones have role to play and there are five hyperglycemic hormones and only one hypoglycemic hormone. The hormones [...]
In human beings, calcitonin is produced from the parafollicular cells (C cells) of the thyroid gland. Calcitonin is made up of 32 amino acids with a molecular weight of 3500. It is a peptide hormone secreted by the parafollicular cells of thyroid gland. Actions: It is a hypocalcemic agent and hence decreases plasma calcium level. When thyroid gland is perfused [...]
