Lab 27. Related Textbooks: A ______ gland is a ductless gland that empties its hormone into the extracellular fluid, from which it enters the blood. The pituitary gland, also known as ______, is located in the sella turcica of the sphenoid bone. Chemical messengers which are released into the blood to be transported throughout the body. An (Endocrine/Exocrine) gland is a ductless gland that empties its hormones into the extracellular fluid, from which it enters the blood. Endocrine glands. These glands do not have ducts. steroid hormone to its cytoplasmic receptor forms a hormone–receptor complex that can move into the nucleus and stimulate transcription of specific genes. In both cases, mRNA produced in response to hormone stimulation is translated into new protein in the cytoplasm. For example, estrogen induces cells in the juvenile from adult. Hormone–secreting organs, called endocrine glands, are referred to as ductless glands because they secrete their chemical messengers directly into extracellular fluid. From there, the chemicals diffuse into the circulation. *causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle. *Insulin accelerates the transport of blood glucose into the body cells where it is oxidized for energy or converted into Glycogen or fat for storage. gland regulates metabolism in humans and other vertebrates. But in frogs, thyroxine has additional effects: it triggers the metamorphosis of a tadpole into an adult, stimulating resorption of the tadpole’s tail and other changes.
