A) perspiration increased sympathetic stimulation of sweat glands possessing alpha receptors. You are just about to perform a clinical procedure for the first time and your palms begin to sweat. This is due to: A) increased sympathetic stimulation of sweat glands possessing alpha receptors. decreased heart rate.

Which of the following may be an effector in an autonomic reflex? A) smooth muscle proprioception The hypothalamus receives sensory input related to each of the following EXCEPT: A) proprioception A and B are correct Which autonomic centers are in the brain stem and are controlled by the hypothalamus? A) vomiting A, B and C are correct. Increased stimulation of the posterior and lateral nuclei of the hypothalamus would result in A) increased body temperature. decreased constriction of the pupils Increased stimulation of the anterior and medial nuclei of the hypothalamus would result in A) increased cardiac output. A, B and C are correct. How does the autonomic nervous system integrate with the reproductive system? A) The hypothalamus helps the limbic system regulate sexual behavior. autonomic The ____ nervous system regulates involuntary actions such as smooth muscle contraction sympathetic Increased stimulation by the ____ division of the autonomic nervous system generally increases heart rate. preganglionic The first motor neuron in any autonomic motor pathway is called a ___ neuron. parasympathetic The ____ division of the autonomic nervous system is also called the craniosacral division because of the cell bodies of its neurons are located in the brain stem and sacral spinal cord. sympathetic trunk _____ ganglia include the superior, middle and inferior cervical ganglia. terminal The _____ ganglia are parasympathetic; they include the pterygopalatine and otic ganglia. Splanchnic nerves ____ contain preganglionic fibers that do not synapse in sympathetic chain ganglia. cranial The _____ parasympathetic outflow consists of preganglionic axons that extend from the brain stem in cranial nerves III, VII, IX or X. autonomic tone The balance between sympathetic and parasympathetic activity is called _____ . hypothalamus The _____ controls the balance between sympathetic and parasympathetic activity. fight or flight Sympathetic activation causes a set of responses designed to protect the body from a real or perceived threat. Collectively, these responses are called the _____ response. rest and digest Parasympathetic activation allows the body to process ingested food and store energy. The parasympathetic response is sometimes called the _____ response. autonomic reflexes Responses that occur when nerve ¬impulses pass through an autonomic reflex arc are ____. receptor The distal end of an autonomic sensory neuron is a _____. posterior The posterior and lateral nuclei of the hypothalamus control the _____ division of the autonomic nervous system. parasympathetic The anterior and medial nuclei of the hypothalamus control the ____ division of the autonomic nervous system.

In these situations, your sympathetic nervous system activates to speed up your heart rate, deliver more blood to areas of your body that need more oxygen or other responses to help your get out of danger.
What is the sympathetic nervous system psychology?The sympathetic nervous system's two primary functions are regulating homeostasis and instigating the fight or flight response. During times of stress, the sympathetic nervous system can dilate the pupils, elevate the heart rate, increase sweating, and elevate the blood pressure.
Which best describes the sympathetic nervous system quizlet?The sympathetic nervous system arouses the body and expends energy. It is responsible for our fight and flight response. The parasympathetic nervous system calms the body and conserves energy. It is responsible for our rest and digest response.
Which of the following is true of the sympathetic division of the autonomic nervous system?The sympathetic division of the autonomic nervous system has its preganglionic neurons cell bodies in the thoracic and lumbar segments of the spinal cord or known as thoracolumbar distribution.
