Health problems associated with thyroid disease include muscle and joint pain, neck discomfort and/or enlargement, bowel problems, changes in hair and/or skin, weight change, depression and anxiety, and fertility problems for females.
Graves disease and Hashimoto's thyroiditis affect the thyroid gland.

Thyroid glands are located in the neck, in close approximation to the first part of the trachea. In humans, the thyroid gland has a "butterfly" shape, with two lateral lobes that are connected by a narrow section called the isthmus. Most animals, however, have two separate glands on either side of the trachea. Thyroid glands are brownish-red in color.Close examination of a thyroid gland will reveal one or more small, light-colored nodules on or protruding from its surface - these are parathyroid glands (meaning "beside the thyroid").The microscopic structure of the thyroid is quite distinctive. Thyroid epithelial cells - the cells responsible for synthesis of thyroid hormones - are arranged in spheres called thyroid follicles. Follicles are filled with colloid, a proteinaceous depot of thyroid hormone precursor.In addition to thyroid epithelial cells, the thyroid gland houses one other important endocrine cell. Nestled in spaces between thyroid follicles are parafollicular or C cells, which secrete the hormone calcitonin.The structure of a parathyroid gland is distinctly different from a thyroid gland. The cells that synthesize and secrete parathyroid hormone are arranged in rather dense cords or nests around abundant capillaries.
The thyroid gland produces two versions triiodothyronine (T3) and tetraiodothyronine (T4) also known as thyroxine. These hormones help regulate metabolism.
The thyroid gland is a very vascular structure that consists of two large lobes connected by a broad isthmus. It is located just below the larynx on either side and in front of the trachea.
The parathyroid glands consist of 4 small glands that are located within the thyroid gland. They produce a hormone called Parathyroid Hormone (PTH). PTH and calcitonin together maintain the homeostasis of Ca++ in the blood. Calcitonin hormone is produced by the thyroid. Together, these two hormones keep the calcium levels in the blood within normal ranges. It reduces the calcium level while its' partner increases the level.
The two lobes of the Thyroid gland being the thyroid and the parathyroid are connected by an isthmus.
You have two pairs of parathyroid glands there besides the thyroid gland. They are of very small size as compared to the thyroid gland.
Two pairs of parathyroid glands are placed on the posterior surface of the thyroid gland. They are of very small size as compared to the thyroid gland.

thyroxine
TSH stands for Thyroid Stimulating hormone it is secreted from the pituitary gland (which is an endocrine gland ) directly into the blood , circulates in the blood till it reaches the thyroid gland where it is picked by certain receptors and cause thyroid gland to secrete thyroid hormone which is of two types T3 and T4
One. The thyroid gland in cats is a bi-lobed structure located next to the trachea. Bi-lobed means the gland splits into two equal parts, so it looks like two separate glands, but it is only one. In addition to the thyroid gland, many cats have extra thyroid tissue elsewhere in the chest cavity. This ectopic (out of place) tissue can function similarly to the tissue found in the thyroid gland, and can also develop the same problems as the thyroid gland; but this extra tissue is not a gland.
The bilobed endocrine gland located over and also lateral to the trachea and the larynx is called the thyroid gland. Also embedded in the thyroid gland on each side are two parathyroid glands.

It produces hormone parathomon. It increases the Ca level and decrease the phosphate level of bllod
There is one feline thyroid gland in a cat. The gland itself has many parts however, including two lobes - one on each side of the trachea (windpipe).
