Thyroxine is transported in the bloodstream and can penetrate the cell membrane under certain conditions. It increases heart rate, breathing rate, and metabolism.
The target for thyroxine is to regulate the body's metabolism by controlling the production of thyroid hormones. Thyroxine is produced by the thyroid gland and helps to maintain normal function of organs and tissues in the body. The target level of thyroxine in the blood is typically determined through thyroid function tests.
A tissue is considered a target tissue when it has specific receptors for a particular hormone or chemical signal. These receptors allow the tissue to respond to the signal by initiating specific biological responses. Target tissues are often the primary sites where the hormone or signal exerts its effects in the body.
The specific tissue acted on by each hormone is referred to as the target tissue or target organ. Hormones are chemical messengers that travel through the bloodstream to interact with specific receptors on target tissues, triggering a physiological response. The effectiveness of a hormone depends on the presence of these receptors, which can vary between different tissues in the body. This selective action allows hormones to regulate various functions, such as growth, metabolism, and reproductive processes.
The tissue specificity of hormones is determined by the presence of specific hormone receptors on the surface of target cells. These receptors are proteins that can only bind to specific hormones, allowing for a precise response in a particular tissue. The binding of a hormone to its receptor triggers a specific signaling pathway that leads to the cellular response.
Target tissues are stimulated by hormones due to the presence of specific receptors that recognize and bind to those hormones. When a hormone binds to its receptor on the target tissue, it triggers a cellular response that can lead to various physiological effects. In contrast, tissues that lack these specific receptors do not respond to the hormone, allowing for selective stimulation and regulation of physiological processes. This specificity ensures that hormones can exert their effects only where needed, maintaining proper bodily functions.
A tissue becomes a target tissue when it is affected or stimulated by a specific amino acid. The target tissue has the appropriate receptors to make it susceptible to the hormone.

Propylthiouracil and methimazole are medications that inhibit production and release of thyroxine and also block tissue effects of thyroxine

The thyroid gland (tissue) produces thyroxine and triiodothyronine. When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, and thyroxine which is commonly referred to as T4. These hormones regulate the metabolism, protein synthesis and sensitivity to other hormones in the body.
Target tissue
The tissue specificity of hormones is determined by the presence of specific hormone receptors on the surface of target cells. These receptors are proteins that can only bind to specific hormones, allowing for a precise response in a particular tissue. The binding of a hormone to its receptor triggers a specific signaling pathway that leads to the cellular response.
The main primary target tissue of the Parathyroid hormone is the bone, but the kidneys are a target as well.
Target tissues are stimulated by hormones due to the presence of specific receptors that recognize and bind to those hormones.
