1. a) Describe the age related changes in the following hormones and b) for

each on explain how this change may increase the vulnerability to one

age associated change for each one :

1) estrogen, is a female sex hormone, during menopause

estrogen levels decrease making one more vulnerable to developing

depression and experiencing mood swings.

2) Vitamin D – Is a hormone produced by the kidneys to

regulate calcium. If you are vitamin D deficient you may experience

depression, and digestive trouble that can be confused with age

associated conditions.

3) parathyroid hormone is produced by the parathyroid glands

and regulates calcium levels throughout the body. When levels are not

regulated it can cause age associated conditions such as anxiety,

depression and digestive problems.

4) ADH or Antidiuretic Hormone is produced in the

hypothalamus. It regulates the release and conservation of water in the

body. Decreased ADH can cause loss of water and increase is of

Dehydration.

5) Insulin – is a hormone produced by the pancreas that

regulates glucose/ sugar levels in the body. If sugar levels are to low or to

high it can cause disorientation, confusion, lethargy, dizziness and other

age associated issues.

6) melatonin – A hormone produced by the pineal gland that

regulates sleep and wakefulness. If melatonin levels are unbalanced it can

cause people to want to sleep excessively or keeps them from sleeping.

This can lead to age associated issues such as dementia and depression.

7) growth hormones are developed in the pituitary gland that

stimulates growth, cell reproduction and cell regeneration. With

unregulated levels of growth hormones one may experience age

Document Summary

If you are vitamin d deficient you may experience depression, and digestive trouble that can be confused with age associated conditions: parathyroid hormone is produced by the parathyroid glands and regulates calcium levels throughout the body. When levels are not regulated it can cause age associated conditions such as anxiety, depression and digestive problems: adh or antidiuretic hormone is produced in the hypothalamus. It regulates the release and conservation of water in the body. Decreased adh can cause loss of water and increase is of. Dehydration: insulin is a hormone produced by the pancreas that regulates glucose/ sugar levels in the body. If sugar levels are to low or to high it can cause disorientation, confusion, lethargy, dizziness and other age associated issues: melatonin a hormone produced by the pineal gland that regulates sleep and wakefulness. If melatonin levels are unbalanced it can cause people to want to sleep excessively or keeps them from sleeping.

13. Urinary tract infections (UTIs) are experienced by many people during their lifetimes. Urinary tract infections can involve any bacterial infection of the urinary system structures; the kidneys, bladder, ureters, or urethra. They are caused by bacteria entering the body through the urethra and traveling upward into the body. Symptoms can range from mild discomfort when urinating to extreme pain and the loss of blood during urination. They occur more frequently in women than men, and are often treated by antibiotics in addition to home remedies, such as drinking more water and drinking cranberry juice.

Based on what you have learned about the cause of urinary tract infections, which of the following precautions would help to prevent reoccurring infections?

Taking pain medication when symptoms occur

Placing a hot pack on the abdomen when symptoms occur

Practicing good hygiene Exercising regularly

14. The nervous system is divided into two major divisions: the Central Nervous System and the Peripheral Nervous System. Those divisions have structures that can be classified as belonging to two different subdivisions: the Somatic and the Autonomic systems. The nervous system can be summarized as a complex system of interconnected nerves and special cells called neurons that are used to transmit information (by means of small electrical impulses). Use the information in the table below to help answer questions about the nervous system. Division Organs & Structures Functions Central Nervous System (CNS) Brain Spinal Cord Nerves This is the bodyâs assessment and communication center. It analyzes the information received from the sensory neurons and responds. Peripheral Nervous System (PNS) Sensory Neurons Ganglia (clusters of neurons) Nerves that connect to one another and to the CNS The sensory neurons react to physical stimuli such as light, sound, heat, and pressure, and transmit that information to the CNS. Subdivisions Description Examples Somatic The Somatic system is comprised of nerves that connect the brain and spinal cord to the muscles of the body and sensory receptors in the skin. Reactions to physical stimuli like heat or light. Using your hand to touch Eating food Autonomic The Autonomic system largely involuntary. This system controls the unconscious functions of the body. Breathing Blood Pressure

Feeling overwhelmed or startled by exposure to very loud noises is likely a reaction to information collected by which subdivision of the nervous system:

Somatic

Autonomic

15. The thyroid gland is perhaps the most well-known member of the pancreatic system. Many adults are screened for thyroid problems during routine physical exams. This butterfly shaped gland is found at the base of the neck and releases hormones that affect the bodyâs metabolism (the way the body uses energy). The thyroidâs two main hormones are T3 and T4, and they affect many body functions, including: â¢ Breathing â¢ Heart rate â¢ Central and peripheral nervous systems â¢ Body weight â¢ Muscle strength â¢ Menstrual cycles â¢ Body temperature â¢ Cholesterol levels Two common disorders associated with the thyroid include hyperthyroidism and hypothyroidism. Some of the symptoms associated with these disorders are listed in the table below. Hyperthyroidism (Too many hormones released) Hypothyroidism (Too few hormones released) Anxiety Irritability or moodiness Nervousness, hyperactivity Sweating or sensitivity to high temperatures Hand trembling (shaking) Hair loss Missed or light menstrual periods Trouble sleeping Tiredness and fatigue Difficulty concentrating Dry skin and hair Depression Sensitivity to cold temperature Frequent, heavy periods Joint and muscle pain A patient complains of arthritis-like pain in the joints of her hands, but tests for arthritis come back negative. The doctor then suggests a thyroid function test. The doctor is most likely concerned about:

High levels of T3 and T4 hormones in the body

Low levels of T3 and T4 hormones in the body
