All the cells that have receptor sites for a given hormone make up the target tissue for that hormone. In some cases, the target tissue is localized in a single gland or organ. In other cases, the target tissue is diffuse and scattered throughout the body so that many areas are affected.
What is a target tissue for a hormone?
Target tissue refers to the intended site that a hormone will affect such as muscle. Receptor site. Receptor sites are special sites located on every target tissue and only communicate with the specific hormone intended for the target tissue.
What makes a tissue a target tissue for a hormone quizlet?
What makes one tissue a target tissue for a hormone and another not a target tissue? Hormones exert their actions by binding to proteins called receptors . A hormone can stimulate only the cells in the hormone tissue that have the receptor for that hormone (specific).
What is target tissue?
Definition: The biological tissue(s) most adversely affected by exposure to a chemical substance .
What is the action and target tissue of growth hormone?
| Anterior Pituitary | Hormone | Growth hormone | Major target organ(s) | Liver, adipose tissue | Major Physiologic Effects | Promotes growth (indirectly), control of protein, lipid and carbohydrate metabolism |

What is a target organ or tissue?
target organ. A tissue or organ upon which a hormone exerts its action ; generally, a tissue or organ with appropriate receptors for a hormone.
What is the target tissue for insulin?
Insulin is a key hormone regulating glucose homeostasis. Its major target tissues are the liver, the skeletal muscle and the adipose tissue . At the cellular level, insulin activates glucose and amino acids transport, lipid and glycogen metabolism, protein synthesis, and transcription of specific genes.
What are the 4 characteristics of hormones?
- They are chemical entities produced by special cells of endocrine glands.
- They are transported to the target cells/ tissue/organ via circulation.
- Their actions are species specific...
- They are active in very minute quantities. ...
- They are mostly water soluble.
- They are low in molecular weight.
What hormone increases blood sugar?
Glucagon , a peptide hormone secreted by the pancreas, raises blood glucose levels. Its effect is opposite to insulin, which lowers blood glucose levels.
What are hormones in animals list four characteristics of hormones?
- Hormones are secreated in small amountsby endocrine glands.
- The hormones are poured directly into blood and carried throughout the body.
- The hormones have their effect at the sight different from the sight at which they are made.
- The hormones act only on target organs.
What do target tissues do?
A target tissue in the endocrine system is the tissue that a particular hormone can exert an effect on . For example, one of the target tissues of the hormone insulin is the muscle. Insulin is a hormone secreted by the pancreas that tells cells to take up glucose and reduces blood glucose levels.
What is estrogens target tissue?
Estrogens have multiple effects on the growth and development of cells in their target tissues, including the uterus, ovary, breast, bone marrow and brain . The hormone regulates the transcription of diverse genes in these tissues via the estrogen receptor, a nuclear transcription factor.

Which hormone is necessary for normal growth of a person?
Diseases & Conditions. Human growth hormone (GH) is a substance that controls your body’s growth. GH is made by the pituitary gland, located at the base of the brain. GH helps children grow taller (also called linear growth), increases muscle mass, and decreases body fat.
