Thyroxine, generally referred to as Tâ‚„, affects target cells by means of a particular method known as the intracellular mechanism. The thyroid gland produces and secretes the thyroid hormone also known as thyroxine. The steps of intracellular mechanism are as follows:
The thyroid gland produces and releases thyroxine into the bloodstream. It attaches to blood transport proteins, which facilitate the delivery of thyroxine to the intended tissues and cells. Thyroxine diffuses across the cell membrane and enters the cytoplasm once it reaches the target cell.
Thyroxine binds to particular receptors called thyroid hormone receptors (TRs) in the cytoplasm. Usually, the target cell's nucleus is where these receptors are found.Target genes are either activated or repressed as a result of a series of intracellular signaling processes that are started when thyroxine binds to TRs.
modifications in cellular metabolism, growth, and development result from the active or suppressed genes. thyroxine acts on target cells by an intracellular process. It enters target cell, interacts with nuclear receptors, and starts to affect the way genes are expressed to control cellular functions.

Imagine you are in an elevator with an important funder that wants to fund your public health research. What kind of research do you want to conduct to learn more about your public health issue? We can use homelessness lack of food etc as a public health issue.
As a public health researcher, I am interested in studying how food insecurity and homelessness affect people's health. Food insecurity refers to the lack of access to sufficient food for an active, healthy life, while homelessness is the condition of not having a stable place to live.
The two issues are closely linked, as homelessness can lead to food insecurity and vice versa. To learn more about these issues, I would like to conduct a study that examines the relationship between food insecurity, homelessness, and health outcomes. The study would involve surveying individuals who are experiencing homelessness and food insecurity to understand the prevalence and severity of health issues such as malnutrition, chronic disease, and mental health problems.
Additionally, we would examine the impact of interventions such as food assistance programs and housing support on improving health outcomes for this population. By conducting this research, we can gain a better understanding of the public health implications of food insecurity and homelessness and identify effective interventions to improve health outcomes for these vulnerable populations.

1)human body regions and
2)why do we divide the human body into different regions?
answer accordingly.
The human body is divided into regions for a variety of reasons. One of the most important reasons is to make it simpler to understand and study the complex structures of the body. By dividing the body into various sections, it's easier to understand how different parts of the body work together to keep us alive and functioning.
In the human body, there are four primary regions: the head, neck, trunk, and limbs. The head region contains the brain, eyes, ears, nose, and mouth, among other organs. The neck region connects the head and trunk regions and includes the trachea, thyroid gland, and various blood vessels. The trunk region contains the heart, lungs, liver, and other major organs.
Finally, the limbs include the arms, hands, legs, and feet, and they are responsible for helping us move and perform everyday tasks. The human body is divided into regions because it makes it easier for healthcare professionals, researchers, and students to understand how the body works. For example, if a doctor is trying to diagnose an issue with a patient's lungs, they can focus on the trunk region of the body and look specifically at the lungs.
Additionally, by dividing the body into regions, it's easier to study different diseases and medical conditions that affect specific parts of the body. By dividing the body into different regions, it becomes possible to better understand how different structures work together and how diseases and medical conditions affect different parts of the body.
It also makes it easier for healthcare professionals to communicate with one another and work together to provide patients with the best possible care.
