receptor
when the chemicals arrive in the right places, the target tissues, they start to do their work. a group of cells that have receptors embedded in the plasma membrane that are complementary in shape to specific hormone molecules. Only these cells will respond to that specific hormone.
It is possible to have symptoms of hormone deficiency even when the blood levels are normal due to a problem with the hormone receptors or the body's inability to use the hormone effectively. This condition is known as hormone resistance, where the target tissues do not respond properly to the hormone present in the blood, leading to symptoms of deficiency.
A hormone cascade refers to a series of events triggered by the release of a hormone that leads to a chain reaction of responses within the body. In this process, one hormone stimulates the release of another hormone, which then triggers additional responses in target tissues or organs. Hormone cascades are important for coordinating various physiological processes in the body.
The primary hormone produced by the testes is testosterone, which plays a crucial role in male reproductive tissues and secondary sexual characteristics.
Acromegaly is the result of hypersecretion of growth hormone
when the chemicals arrive in the right places, the target tissues, they start to do their work. a group of cells that have receptors embedded in the plasma membrane that are complementary in shape to specific hormone molecules. Only these cells will respond to that specific hormone.
Target cells have specific receptors that recognize and bind to the hormone, triggering a response. Non-target cells either lack the necessary receptors or have receptors that do not bind the hormone, so they do not respond to it. This specificity allows hormones to selectively regulate the functions of specific tissues or organs in the body.
Different tissues have varying permeability to molecules, which impacts the rate of diffusion. Tissues with higher permeability, such as lungs or intestines, allow for faster diffusion due to more open pathways for molecules to pass through. In contrast, tissues with lower permeability, like skin or brain tissue, experience slower diffusion rates as molecules encounter barriers to passage.
Tissues may not be affected by hormones if they do not have receptors for those specific hormones. Hormones can only exert their effects on tissues that have the appropriate receptors to bind and respond to them. This specificity helps to ensure that each hormone can target the specific tissues and organs it needs to regulate.
Thyroid hormone is the hormone that controls how each cell in the body metabolizes energy.
The tissue/cells need a receptor that can interact with that hormone in order to respond to it. This receptor may be on a cell membrane, inside the cell, or even inside the nucleus (in the case of steroid hormones, for example.) Like many organic chemicals in the body, they have structures which result in certain parts of the molecule being presented to cells (active sites). Because cells and tissue have different structures as well, only certain cells will react to the presence of a particular hormone. Many hormones have antagonist hormones that cause an opposite effect. This helps control negative feedback when the target organ's hormone levels are too high.
Calcitonin
calcitonin
It is possible to have symptoms of hormone deficiency even when the blood levels are normal due to a problem with the hormone receptors or the body's inability to use the hormone effectively. This condition is known as hormone resistance, where the target tissues do not respond properly to the hormone present in the blood, leading to symptoms of deficiency.
Hormone
Calcitonin is the hormone that works with parathyroid hormone to regulate calcium levels in the blood and tissues. Calcitonin helps to lower blood calcium levels by promoting calcium deposition in bones.
