The Nervous System, Endocrine System, and Homeostasis

When blood sugar levels are below normal, the pancreas responds by producing
1. calcitonin
2. insulin
3. glucagon
4. parathyroid hormone
When blood sugar levels are above normal, the pancreas responds by producing
1. calcitonin
2. insulin
3. glucagon
4. parathyroid hormone
Hormones produced in the pancreas include
1. calcitonin
2. insulin
3. glucagon
4. parathyroid hormone
Which of the following WOULD NOT be a homeostatic response to an elevated level of calcium in the blood?
1. secretion of calcitonin
2. secretion of parathyroid hormone
3. release of stored calcium from bone tissue
4. decreased absorption of calcium in the intestine
5. reabsorption of calcium by the kidneys
The homeostatic control of blood sugar by insulin and glucagon is an example of
1. a reflex arc
2. a negative feedback loop
3. a positive feedback loop
4. a combustion reaction
The primary storage site for calcium in the body is
1. the kidney
2. the liver
3. bone tissue
4. the thyroid gland
The Central Nervous system is composed of
1. the sympathetic and parasympathetic
2. the brain and spinal cord
3. motor nerves and sensory nerves
4. the autonomic nerves
In the image above, you see a common technique used in a physical examination which is intended to measure a patient's
1. central nervous system
2. reflex arc
3. muscle strength
4. vision

In this diagram of a reflex arc, the label "B" identifies
1. a sensory neuron
2. a motor neuron
3. an interneuron
4. the brain
In this diagram of a reflex arc, the label "C" identifies
1. a sensory neuron
2. a motor neuron
3. an interneuron
4. the brain

The advantage of a reflex arc in responding to a painful stimulus is that it saves reaction time by bypassing the
1. sensory nerves
2. brain
3. motor nerves
4. spinal cord
Which of the following would be physiologic changes brought on by the "Fight or Flight" response?
1. increased heart rate
2. increased blood flow to the stomach and intestines
3. increased production of saliva
4. increased breathing rate
5. dilation of the pupils
6. increased blood flow to skeletal muscles
Involuntary muscle contraction, such as those in the pupil of the eye, digestive tract, and diaphragm are the responsibility of the
1. cerebrum
