Document Summary

Autonomic sensory neurons oin our visceral organs and our blood vessels. Integrating centers osends signals from the sensory neurons to the cns ointerprets the info. Autonomic motor neurons oprorogated from the cns and go to specific tissues that regulate our smooth muscle, cardiac muscle, and our glands. Enteric division onerve network within the regions of our gi tract. Somatic nervous system oconsciously perceived sensations oincludes both sensory and motor neurons oconveys input from somatic and special senses. Main input comes from autonomic (visceral) sensory neurons oautonomic neurons regulate visceral activities osympathetic and parasympathetic divisions. Preganglionic neuron oaxons leave the cns in a myleinated neuron and go to an autonomic ganglion. Postganglionic neuron oonce it leaves the autonomic ganglion oun-myleinated. Dual innervation ogetting information from sympathetic and parasympathetic. Autonomic plexus in the thorax, abdomen, and pelvis: Tangled networks of pre and post ganglion neurons form plexuses.

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 body’s 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 body’s metabolism (the way the body uses energy). The thyroid’s 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

There was a horrific traffic accident and you run to help the victims. You feel a pulse from his carotid artery ,however the medic comes along and gets no blood pressure as he measures it from the arm. He claims the victim is dead. You think which of the following?

A

Medic is not correct since it is the difference between heart rate and blood pressure that determines life. No heart rate only means tha the sympathetics have stopped vasoconstricting the blood vessels.

B

Medic is correct since it is common to not have a blood pressure of 120/80 and no pulse due to stress as was discussed in class.

C

Medic is incorrect since there is a pulse. This means the person is still alive.

D

Medic is correct since there is no blood pressure there is no life.
