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 [...]
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.

In this article we will discuss about:-1. Secretion of Thyroid Glands 2. Actions of the Thyroid Gland 3. Regulation 4. Thyroid Function Tests. Secretion of Thyroid Glands: The hormones secreted by this gland are: i. Thyroxine (T4) ii. Triiodothyronine (T3) iii. Thyrocalcitonin (calcitonin) Among the three hormones, the follicular cells of the gland secrete the first two hormones (T3 and [...]
