The Endocrine System

• HORMONES ACT ON SPECIFIC CELLS
• Amino - Acid Based Hormones are water-soluble
  hormone made of amino acids.
• Steroid Hormones fat-soluble hormone derived
  cholesterol.
• Once hormones are secreted into the blood or
  extracellular fluid they are transported to a
  target cell(s) where they will have a desired
  effect.

bjidAP13704 Actions of Hormones
30
The Endocrine System

• HORMONES ACT ON SPECIFIC CELLS
• Protein based hormones bind to a specific
  receptor on the cell membrane of the target cell.
  

31
The Endocrine System

• HORMONES ACT ON SPECIFIC CELLS
• This binding of the hormone and membrane
  receptor causes a series of internal changes to
  occur with in the target cell.

32
The Endocrine System

• HORMONES ACT ON SPECIFIC CELLS
• Examples of changes include transcription,
  exocytosis or endocytosis, membrane channels to
  open or close.
• See textbook Page 986

33
The Endocrine System

• HORMONES ACT ON SPECIFIC CELLS
• Examples of changes include transcription,
  exocytosis or endocytosis, membrane channels to
  open or close.
• See textbook Page 986

34
The Endocrine System

• HORMONES ACT ON SPECIFIC CELLS
• Steroid hormones are all derived from
  cholesterol, a lipid. It can diffuse directly
  through the cell membrane, which is also made up
  of lipids.

35
The Endocrine System

• HORMONES ACT ON SPECIFIC CELLS
• Steroid hormones usually combine with nuclear
  membrane receptors. This produces an activated
  hormone-receptor complex.

36
The Endocrine System

• HORMONES ACT ON SPECIFIC CELLS
• The receptor hormone complex will bind directly
  to a gene and causing transcription of the gene
  to occur, leading to the production of a new
  protein.
• See textbook Page 980-981

37
The Endocrine System

• THE RELEASE OF HORMONES MUST BE REGULATED
• Negative Feedback mechanism used in
  homeostasis to keep monitored variable within a
  certain range. A change in one direction
  stimulates two control mechanisms to counteract
  further change in the same direction.

38
Homeostasis is one of the fundamental
characteristics of living things. It refers to
the maintenance of the internal environment
within tolerable limits. All sorts of factors
affect the suitability of our body fluids to
sustain life these include properties like
temperature, salinity, acidity, and the
concentrations of nutrients and wastes. Because
these properties affect the chemical reactions
that keep us alive, we have built-in
physiological mechanisms to maintain them at
desirable levels. When a change occurs in the
body, there are two general ways that the body
can respond. In negative feedback, the body
responds in such a way as to reverse the
direction of change. Because this tends to keep
things constant, it allows us to maintain
homeostasis. On the other hand, positive feedback
is also possible. This means that if a change
occurs in some variable, the response is to
change that variable even more in the same
direction. This has a de-stabilizing effect, so
it does not result in homeostasis. Positive
feedback is used in certain situations where
rapid change is desirable. To illustrate the
components involved in negative feedback, we can
use the example of a driver trying to stay near
the speed limit. The desired value of a variable
is called the set point. Here, the set point is a
speed of 55 mph in controlling body temperature,
the set point would be 98.6 degrees. The control
center is what monitors the variable and compares
it with the set point. Here, the control center
is the driver for body temperature, it would be
the hypothalamus of the brain. If the variable
differs from the set point, the control center
uses effectors to reverse the change. Here, the
effector is the foot on the accelerator pedal in
controlling body temperature, it would include
the glands that sweat and the muscles that shiver.

Hormone Secreted by Target Tissue Effects
Follicle Stimulating Hormone Pituitary Gland Ovaries and Testes Regulates the development of male and female gametes
Cortisol Adrenal gland Liver Reaction to long term stress increases blood glucose levels (energy)
Corticotropin releasing hormone (CRH) Hypothalamus Pituitary Gland Reaction to stress tells pituitary gland to release adrenocorticotropic hormone (ACTH) which leads to increased blood glucose
Adrenocortico-tropic hormone (ACTH) Pituitary gland Adrenal gland Stimulates the release of cortisol and other steroid hormones from the adrenal cortex increases blood glucose
Luteinizing Hormone (LH) Pituitary gland Ovaries and Testes Stimulates the release of egg in females stimulates secretion of sex hormones (testosterone, estrogen and progesterone)
Prolactin Pituitary gland Mammary glands Stimulates milk production in breasts
Growth Hormone (GH) Pituitary gland All tissues Stimulates protein synthesis and bone and muscle growth
Thyroid Stimulating Hormone (TSH) Pituitary gland Thyroid gland Stimulates the synthesis and release of thyroid hormone from the thyroid gland
Antidiuretic Hormone (ADH) Pituitary gland Kidneys, blood vessels Stimulates reabsorption of water from the kidney constricts blood vessels
44
Hormone Secreted by Target Tissue Effects
Oxytocin Pituitary gland Mammary glands, uterus Stimulates uterine contractions and milk production
Calcitonin Thyroid gland Bone tissue Stimulates calcium to be deposited in bone tissue in order to lower blood calcium levels
Parathyroid Hormone (PTH) Parathryroid glands (back of thyroid) Bone tissue kidney Stimulates bone cells to break down and release calcium to blood stimulates kidneys to reabsorb calcium from urine activates vitamin D which helps absorb calcium in intestines
Epinephrine (adrenaline) Adrenal gland Liver, muscle Increases blood sugar, increases blood pressure, increases heart rate in response to stress fight or flight
Norepinephrine (noradrenaline) Adrenal gland Liver, muscle Decreases blood sugar, decreases blood pressure, decreases heart rate in response to no stress rest and digest
Aldosterone Adrenal gland Kindey, sweat glands Retrieves sodium from fluid filtered in kidney (urine) increases volume of blood which increases blood pressure stimulates kidneys to get rid of potassium
Insulin Pancreas (islets of langerhans) Liver Stimulates liver to build glycogen from glucose and helps cells take up glucose ? decreases blood glucose
Glucagon Pancreas (islets of langerhans) Liver Stimulates liver to break down glycogen to glucose ? increases blood glucose
