Hormones are special PROTEINS, which act as signals. 2. Describe hormones and how they are transported throughout the body. Hormones are special PROTEINS, which act as signals. Hormones are transported in the BLOOD.

Hormones affect TARGET CELLS. 3. Identify the cells affected by hormones and the structure that hormones attach to on those cells. Hormones affect TARGET CELLS. Hormones attach to RECEPTORS on the target cells.

Identify structure B. Support your answer. Explain why cell C is the target cell.

4. Compare and contrast the nervous and endocrine system. They BOTH regulate the body. They BOTH send messages to different parts of the body. The endocrine system releases HORMONES. The nervous system transmit IMPULSES. Endocrine system messages are chemical. Nervous system messages are electrical and chemical. The endocrine system is made up of endocrine glands. The nervous system is made up of the brain, spinal cord and nerves.

Identify the gland that releases human growth hormone. Pituitary gland

Pituitary gland

3. Identify the function of human growth hormone. Tells muscle cells to grow, reproduce, or repair themselves.

Master gland

Verne Troyer, 30, describes himself as a "little person or dwarf," is 2 feet, 8 inches tall.

14-year old Khagendra Thapa Magar shown in the picture with another boy is only 50cm (20 inches) tall and has been submitted to the Guinness world record as the world's smallest person. The previous world record holder was a Jordanian boy at 25.5 inches tall. Weighing only 4.5 kilograms, he is shown in exhibitions to collect fund for his education.

Robert Pershing Wadlow is the tallest person in medical history Robert Pershing Wadlow is the tallest person in medical history. He is often known as the "Alton Giant" because of his Alton, Illinois hometown. Robert Wadlow reached 8 feet 11.1 inches in height and weighed 490 pounds at his death. His great size and his continued growth in adulthood was due to an abnormally high level of human growth hormone. He showed no indication of an end to his growth even at the time of his death.

Robert Wadlow's size began to take its toll: he required leg braces to walk, and had little feeling in his legs and feet. Despite these encounters, Robert Wadlow was never confined to a wheelchair. On July 4, 1940, a faulty brace irritated his ankle, causing a blister followed by an infection. Doctors treated him with a blood transfusion and emergency surgery, but his condition worsened and on July 15, 1940, he died in his sleep. He was 22.

6. Identify the hormone that is produced by this gland. Thyroxine

This X-ray shows how an enlarged right lobe of the thyroid has moved the trachea to the patient's left. The trachea (outlined in light yellow) should be straight from the mouth down to the lungs, but in this patient it is compressed and displaced far to the left.

7. Identify the glands that regulate calcium metabolism. Parathyroid glands

8. Identify the location of these glands. Located ON THE thyroid.

Pituitary gland Parathyroid gland Thyroid gland

10. Identify the glands that increase the rate of certain body processes in times of stress. Adrenal glands

Located ON TOP of each kidney 11. Identify the location of these glands. Located ON TOP of each kidney

12. Identify the hormones released by these glands. Adrenaline

Pancreas Islets of Langerhans 14. Identify the gland that regulates blood glucose levels. Pancreas Islets of Langerhans

15. Identify the location of this gland. Located in the digestive system, below the stomach.

Pituitary gland Parathyroid gland Thyroid gland Adrenal glands Pancreas

16. Identify the hormones released by this gland. Insulin and glucagon

Insulin causes blood glucose levels to decrease. 17. Describe the function of insulin. 18. Describe the function of glucagon. Insulin causes blood glucose levels to decrease. Glucagon causes glucose levels to increase.

19 or 20. Identify the sex glands. Gonads

Female sex glands  OVARIES Male sex glands  TESTES 20,21 or 22. Identify the sex glands. Female sex glands  OVARIES Male sex glands  TESTES

OVARIES release ESTROGEN TESTES release testosterone. 21, 23 or 24. Identify the hormones released by the female and male sex glands. OVARIES release ESTROGEN TESTES release testosterone.

Regulate the development of secondary sex characteristics. 22 or 25. Describe the function of the male and female sex hormones. Regulate the development of secondary sex characteristics.

Pituitary gland Parathyroid gland Thyroid gland Adrenal glands Pancreas Gonads

Let’s summarize: Identify the chemical secreted by endocrine glands. Identify the cells affected by hormones. 3. How are hormones transported to target cells? 4. Identify the structures hormones attach to on the surface of the target cell. HORMONES TARGET CELLS BLOOD RECEPTORS

The endocrine system consists of endocrine glands The endocrine system consists of endocrine glands. What do all of these glands have in common?

5. Identify the hormone (A or B) that will affect the target cell. b. Target cell 2: Hormones A and B c. Target cell 3: Hormone B 1 2 3

A B X Where is the secreting cell found? Identify the circular structures. Identify structure X. Identify the cell that is the target cell. Support your answer.

Homeostasis in living things is regulated by the action of The nervous system, only The endocrine system, only Both the nervous and endocrine systems Neither the nervous nor the endocrine system

Which substances are found on cell surfaces and respond to nerve signals? starches and simple sugars subunits of DNA vitamins and minerals receptor molecules

Hormones and secretions of the nervous system are chemical messengers that store genetic information carry out the circulation of materials extract energy from nutrients control and coordinate system interactions

A student accidentally places her hand on a tack and quickly pulls her hand away. The tack represent a stimulus an impulse a response an effector

In a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through  (1.) a receptor  (2.) an interneuron  (3.) an effector  (4.) the brain

A change that initiates an electrochemical message along a neuron is known as a stimulus a response an impulse a synapse

When a child runs to his mother after hearing a clap of thunder, the clap of thunder would serve the nervous system role of acting as a(n) stimulus response effector receptor

Adding one drop of dilute hydrochloric acid to the water surrounding a hydra caused the hydra to contract. The acid acted as 1. a response 2. a stimulus 3. a neurotransmitter 4. an impulse
