1. Which of the following is an accurate depiction of the somatic nervous system and the autonomic nervous system as they support the peripheral nervous system? O The somatic nervous system connects the surface of the body with the central nervous system, and the autonomic nervous system connects the spinal cord to internal organs. O The autonomic nervous system takes care of the internal organs. Muscle responses in the somatic nervous system are automatic. O Within the somatic nervous system, the inner organs send sensory information to the brain. Within the autonomic nervous system, you get the senses of pressure, warmth, or pain. O The autonomic nervous system includes sensory impulses, motor impulses, and nerves. The somatic nervous system includes a system that reacts to increased activity in one or more internal organs.

1. What statement is true regarding the peripheral nervous system (PNS)? x The efferent division of the PNS is transmits information from sensory receptors to the brain X The somatic division of the PNS refers to the innervation of the internal organs of the body X The ventral root of the spinal nerve transmits afferent information to the spinal cord x The autonomic nervous system is a branch of the visceral efferent division of the PNS
5.. How would your nervous system respond if you encounter a snake on a hiking trail? The parasympathetic nervous system would send signals to increase the heart rate, decrease salivation, and increase respiration The somatic nervous system sends signals to the central nervous system to increase heart rate and respiration. The sympathetic nervous system would send signals to increase the heart rate, decrease salivation, and increase respiration The autonomic nervous systern would send signals to the somatic nervous system to increase respiration and heart rate
Which of the following statements regarding the functions of the nervous system is/are true? Check all that apply. Check All That Apply The nervous system is an organ system dedicated to control and coordination of body cells. The nervous system communicates via hormones. Sensory nerve endings transmit messages to the spinal cord and brain. The nervous system's major subdivisions are the CNS and PNS. The nervous system responds slowly and relies on the blood stream to carry its neurotransmitters.
The nervous system helps all parts of the body communicate with each other. It is made up of several sub-divisions with each subdivision havingstructural and functional characteristics that distinguish it from the others. Complete the diagram to show all the missing sections and explain their functions and where relevant their relationships to each other.
Which of the following best describes the sympathetic nervous system? i) Associated with stressful situations ii) Norepinephrine may be involved iii) Associated with voluntary responses i only O ii only Oi and ii only i and iii only O i, ii, and iii
Match the concept with the correct section of the nervous system. 1 + Central nervous system 1. Consists of the brain and spinal cord 2. Responsible for sending sensory + Autonomic nervous system messages to the CNS and sending motor messages to muscles and glands + Parasympathetic nervous system 3. Responsible for voluntary control: sense receptors send messages to the CNS and + Peripheral nervous system impulses travel from the CNS to effectors (muscles) • Sympathetic nervous system 4. Responsible for involuntary control: controls glandular secretions (enzymes + Somatic nervous system and hormones) and the function of smooth and cardiac muscles 5. Activated in emergencies and in times of stress 6. Activated when the body is calm, at rest, and digesting a meal
Visit this site (http://openstaxcollege.org/l/neurolab) to see a virtual neurophysiology lab, and to observe electrophysiological processes in the nervous system, where scientists directly measure the electrical signals produced by neurons. Often, the action potentials occur so rapidly that watching a screen to see them occur is not helpful. A speaker is powered by the signals recorded from a neuron and it pops each time the neuron fires an action potential. These action potentials are firing so fast that it sounds like static on the radio. Electrophysiologists can recognize the patterns within that static to understand what is happening. Why is the leech model used for measuring the electrical activity of neurons instead of using humans?
Match the following components of the nervous system with their correct descriptions Interneurons Sensory neurons Motor neurons Nerve net Neurons that send signals to effector cells like muscles and glands that affect change Neurons that carry signals from the environment to the central nervous system from the peripheral nervous system Neurons that transmit signals between other neurons, part of the CNS A diffuse arrangement of neurons that are found in jellyfish and other cnidarians

Your nervous system is organized into two broad anatomical divisions: the central nervous system (consisting of the brain and spinal cord) and the peripheral nervous system (PNS). Your PNS is further organized into two functional divisions. If you tap your knee, the signal to act is carried via your to the muscles in your knee. In contrast, the signals that pass via the are involuntary and act primarily to regulate your body's internal environment. This involuntary nerve system is further organized into three divisions. If you need a sudden burst of energy, your is activated to help you act quickly. In contrast, if you are relaxing and conserving energy, then it is your that is primarily in action. The third division is your which helps control the components of the digestive system.
1. What are an afferent neuron and efferent neuron? What are efferent components of the facial nerve and their actions? 2. Under certain circumstances, axons in the peripheral nervous system can regenerate after sustaining damage. Why is axonal regeneration in the central nervous system much less likely? 3. At a healthy myoneural junction, acetylcholine is responsible for stimulating muscle activity. What mechanisms are in place to prevent the continuous stimulation of a muscle fiber after the neurotransmitter is released from the presynaptic membrane?
Classify the following characteristics to demonstrate your knowledge of differences between the autonomic and somatic divisions of the nervous system. Neurons release acetylcholine that binds to nicotinic acetylcholine receptors located on the effector organs Can lead to excitation or inhibition of the Neurons are also called motor neurons effectors Receptors on effector organs are also responsive to epinephrine that is released into the blood by the adrenal medulla Innervates smooth and cardiac muscle, glands, and Gl neurons Neurons release norepinephrine that binds to adrenergic receptors located on the effector organs Has two-neuron chain between the CNS Single neuron between the CNS and effectors Neurons release acetylcholine that binds to muscarinic acetylcholine receptors located on the effector organs and effectors Can lead only to excitation of the effectors Activates skeletal muscles Autonomic Nervous System Somatic Nervous System
