Nervous System (answer them all with "just few words no need for details" and I will rate you.
1-What are the three key senses of the hypothalamus? What did we call the hypothalamus in the homeostatic regulation of body temperature? What endocrine gland is regulated by the hypothalamus?
2-The pineal gland secretes hormones that regulate circadian rhythms. Melatonin is the primary hormone that regulates these cyclical processes in the human body. How is its secretion regulated? Are plasma levels of melatonin high or low in the daytime? How could you induce sleep during the day without ingestion of any chemicals or medicine?
3-What are the neurotransmitters involved in mood? Anxiety? Pharmacologically, how is altered mood (i.e., depression) treated? Can you explain the mechanism of the selective serotonin reuptake inhibitor (SSRI) example provided? Pharmacologically, how is anxiety treated? Can you explain the mechanism of the benzodiazepine example provided?

2. The nervous system has how many major categories?
3
2
13
4
3. Which major category of the nervous system contains both the Somatic and the Autonomic divisions?
Central Nervous System
Peripheral Nervous System
Neither of these
Both of these
4. Which organ or structure helps to control the master endocrine gland (pituitary gland)?
The pancreas
The thorax
Peyerâs patches
The hypothalamus
6. This tiny gland is located at the base of the brain and produces the hormone melanin.
Parathyroid
Pituitary
Hypothalamus
Pineal
7. These glands are situated right above the kidneys. The hormones produced by these glands help us to cope with stress.
Thyroid
Adrenals
8. The hormones necessary for the production of sperm are produced in the __________.
Kidneys
Testes
Ovaries
None of the above
9. The bloodstream assists the endocrine organs and structures by:
Removing hormones from the body
Delivering hormones to target cells
Delivering hormones to secretory cells
The bloodstream does not come into contact with endocrine structures or organs 10. The pancreas _____________.
Is a master gland that controls many other glands
Produces progesterone and oestrogen
Is a salivary gland
Regulates blood sugar, aid in digestion
11. The basic function of the endocrine system is ________ in nature.
Digestive
Reproductive
Hormonal
Proximal
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: ⢠Breathing ⢠Heart rate ⢠Central and peripheral nervous systems ⢠Body weight ⢠Muscle strength ⢠Menstrual cycles ⢠Body temperature ⢠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
