Hormones act at specific target organs because these organs contain what specific for the hormone?
target cells
What chemical messenger has specific regulatory effects on certain cells?
Hormones and neurotransmitters
Is the responsiveness of cells to hormones determined by the presence or absence of specific hormone receptor proteins?
True
Why are hormones refferred as chemical messengers?
Because they are chemicals that convey a message to another part of they body to secrete this, contract that, breakdown this substance, etc. They carry "messages" that tell other parts or cells what to do.
What are the structures that allow hormones to bind to their target cells?
Receptors allow hormones to bind to their target cells.
How do circulating hormones differ from paracrines and autocrines with reference to their target cells?
Paracrines are a group of local hormones that work on nearby cells. Autocrines stimulate the same cell and circulating hormones can travel long distances to stimulate cells. Hormones only stimulate cells that have their specific receptor.
Hormones are essential to maintaining homeostasis mainly because?
they cause specific responses in specific cells.
Hormones act at specific target organs because these organs contain what specific for the hormone?
target cells
What chemical messenger has specific regulatory effects on certain cells?
Hormones and neurotransmitters
How do you some hormones affect only certain cells in the body but not others?
These cells have specific types of receptors on their membranes.
Which hormone affect only certain cells?
Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.
What chemicals are produced and released by neurons that convey information between most nerve cells?
neurotransmitters
Is the responsiveness of cells to hormones determined by the presence or absence of specific hormone receptor proteins?
True
Which hormone is released when you sleep at night and how does it work inducing sleep?
Hormones are chemical messengers that are secreted by the endocrine glands into the blood. Hormones are transported via the bloodstream to reach specific cells, called target cells, in other tissues. They produce a specific effect on the activity of cells that are remotely located from their point of origin.
Why does hormone act only on specific cell types in a organism and not others?
Hormones can only be detected by cells that have the specific receptor which binds to the hormone. This means that the hormone only acts on the cells with its receptor and the other cells do not respond.
What type of cells are hormones?
Hormones are not cells but chemicals released by cells to affect changes in other cells.
What are the functions of hormones in the body?
Hormones are called "chemical messengers". They carry information to cells in a way similar to nerve impulses. The nerve impulses are cell to cell. Hormones direct activities.
