Thyroid gland-brief notes

Thyroid gland

In contact with the trachea, lies a powerful gland named as Thyroid gland, a gland that has an enormous power over our body.Structure: consists of two lobes, each one has lobules, these lobules contain cells named follicles, functioning as a store to the hormones the thyroid gland se

nds, they are Thyroxine& Triiodothyronine or T3 and T4 respectively so Iodine is an essential element that mainly build up these hormones.

The thyroid gland has various functions and effects over the human body, it's role is to ensure the proper work of the body's cells by delivering these hormones to every single cell, it instruct every cell when to consume oxygen for aerobic respiration and nutrients for maintaining the body's metabolism that means it has a major function in our physical and mental growth, it makes sure that our heart pumps blood properly.
The thyroid gland is controlled by the human body's MASTERMIND gland which is the ''Pituitary gland'', this gland can be found deep below brain, it makes sure when the thyroid gland secrets it's hormones, the pituitary's role is to sense if the hormonal levels are too low or too high by secreting a hormone named ''TSH'' thyroid stimulating hormones which induce/stimulates the thyroid gland.

Everything has disorders, 1st:Hyperthyroidism where the thyroid gland sends a lot of hormones that means the cells are overloaded with instructions making the individual overactive experiencing a high metabolism signaled by:1)faster heart beat 2) constant hunger 3)high weight loss 4) sleep difficulty and much more
On the other hand, 2nd disorder: Hypothyroidism where the thyroid gland sends a few hormones that means cells doesn't have many messengers to guide them, therefore, metabolism diminishes to a low level. signaled by:1) high weight gain 2) sluggishness( delay) ( lag) 3)sensitivity to cold 4) swelling joints 5)depression and much more
Well I really have to admit that the study of hormones is amazing, we can literally say it is what our metabolism based on, it is the key the ignites our metabolism.
