Chemical Messenger Research Paper

Describe the four classes of chemical messengers.
The human body contains chemical messengers. There are four groups of chemical messengers within the human body. Each chemical messenger are unique in their own way, having different functions throughout the body. The four groups are as follows in no specific order: Autocrine, paracrine, neurotransmitter, and endocrine. Neurotransmitter chemical messengers are let out by neurons where they are deposited into the synaptic cleft. Neurotransmitter chemical messenger travel short distance’s activating adjoining cells by triggering nearby cells.

An example of chronic hormone secretion would be TSH. TSH is in everyone’s body. IF TSH levels in one’s body becomes out of normal range, this can cause thyroid disorders.
Acute hormone secretion occurs when there is a disturbance in the hormone’s concentration and levels differentiate with stimulation. Example of acute hormone secretion would be the release of epinephrine in the body. For example, if a person is afraid of lightning and they are caught in a lightning storm the body release epinephrine in result of fear.
Episodic hormone secretion is when hormones are distributed occurs when hormones are introduced into the body at regular times and absorptions. An example of episodic hormone secretion would be the body’s secretion of insulin by the pancreas for leveling blood sugar levels in ones bloodstream. For example if a person skips meals and becomes hypoglycemic the body will secrete insulin to bring blood sugars back to normal.
What characteristics of a hormone receptor make it specific for one type of
Prolactin-releasing hormone and prolactin-inhibiting hormone. Growth hormone–releasing hormone, Thyrotropin-releasing hormone, Corticotropin-releasing hormone, Gonadotropin-releasing hormone, growth hormone–inhibiting hormone.
What are the target tissues of thyroid hormones? How do thyroid hormones alter the activities of their target tissues? What effects are produced?
Almost all cells of the human body are target by thyroid hormones. Activity on targeted tissues can be altered by blood levels, meaning onset, durations and half-life of the hormone. Thyroid hormones can affect an individual by means of affecting how one metabolizes. For example if ones metabolism decreases they may gain more weight.
