1. Hormones that affect metabolism
Ms Manning
SBI4U0

2. Thyroid Gland Lies in the anterior neck just below the larynx.
Two lobes, located on either side of the trachea.
Beginning course details and/or books/materials needed for a class/project.

3. Thyroid Gland - Hormones
Thyroxine (T4) & Triiodothyronine (T3)
Regulate body metabolism and the growth and differentiation of body tissues
T4 stimulates the oxidation of glucose and other nutrients
 T4 =  metabolism
A schedule design for optional periods of time/objectives.

4. T4 and T3 Trigger : Target: Effect:
low MR/cold  release of TSH from ant. pit.
** structures require iodine!
Target:
Many tissues
Effect:
Increase metabolism
Protein synthesis
Increase production of ATP
Objectives for instruction and expected results and/or skills developed from learning.

5. Feedback Loop - Metabolism
Hypothalamus releases thyroid releasing hormone (TRH)
Receptors in hypothalamus detect low MR
Stimulus – Low Metabolic Rate
Anterior pituitary releases thyroid stimulating hormone (TSH)
Relative vocabulary list.
Response – body cells increase oxidation of glucose
  MR
Thyroxine released by thyroid

6. Low Metabolic Rate
Stimulus – Low Metabolic Rate/Cold Monitor – receptors in hypothalamus Co-ord #1 – hypothalamus releases thyroid releasing hormone (TRH) Co-ord #2 – pituitary gland releases thyroid stimulating hormone (TSH) Co-ord #3 – thyroid gland releases thyroxine Regulator – body cells oxidation of glucose
Introductory notes.

7. Metabolism Calcitonin Trigger increased blood calcium Target - bone
Effect - deposit calcium in bone
A list of procedures and steps, or a lecture slide with media.

8. Thyroid Disorders Hypothyroidism, or Myxedema Myxedema symptoms:
Facial bloating
weakness
cold intolerance
lethargy
altered mental status
oily skin and hair
Goiter (xs TSH)

9. Goiter
Low iodine = thyroxine production drops = more and more TSH produced = over stimulus of the thyroid = cells continue to develop = enlarged thyroid

10. Hyperthyroidism Caused by an increase in T4/T3 production
Commonly called Graves’ disease
Signs and symptoms:
insomnia, fatigue
tachycardia
hypertension
heat intolerance
weight loss
Long term hyperthyroidism causes Exopthalmos

11. Parathyroid Glands small, pea-shaped glands, located in
the neck near the thyroid
usually 4 - can vary
regulate the level of calcium in the body
Example graph/chart.

12. Parathyroid Hormone (PTH)
parathormone
Trigger:
low level of calcium in blood
Target :
bone, kidney, intestine
Effect :
reabsorb calcium into blood
Hypocalcemia can result if parathyroids are removed or destroyed.
