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 regulation of PTH and calcitonin secretion. Decrease in plasma calcium level increases PTH secretion and when plasma calcium level increases, there will be increased secretion of calcitonin. (Fig. 6.52) Apart from the plasma calcium level, some of the other factors which can affect the secretion of PTH are: i. Decreased plasma magnesium [...]
The following points highlight the four main endocrine functions of adrenal cortex. The functions are: 1. Adrenal Cortex 2. Adrenal Androgens 3. Aldosterone 4. Endocrine Function of Adrenal Medulla. Function # 1. Adrenal Cortex: It is divisible into three different layers, from outwards within will be: i. Zona glomerulosa ii. Zona fasciculata iii. Zona reticularis. All three layers secrete the [...]
