Summary Introduction
To explain: The way in which the animals with the most complex and simplest bilateral nervous system might filter and respond to these environmental stimuli.
Introduction: The nervous system includes the nerve cell networks involved in transmitting nerve impulses between body parts. A progressive increase observed in the complexity of the nervous system in various animal phyla and this reflects the stages in the nervous system evolution.

Many neurotoxins have been used extensively in physiological studies of neurons. When comparing tetrodotoxin found in puffer fish and batrachotoxins from poison dart-frogs, the former had no effect on a neurons resting potential but completely stopped its action potential, whereas the later toxin immediately initiates depolarization of a neuron but prevents repolarization. Can your group hypothesize how these toxins affect the nerve transmission differently?
Visit this site (http://openstaxcollege.org/l/nervetissue3) to learn about how nervous tissue is composed of neurons and glial cells. Neurons are dynamic cells with the ability to make a vast number of connections, to respond incredibly quickly to stimuli, and to initiate movements on the basis of those stimuli. They are the focus of intense research because failures in physiology can lead to devastating illnesses. Why are neurons only found in animals? Based on what this article says about neuron function, why wouldn't they be helpful for plants or microorganisms?
Alcohol addiction is a condition in which a person experiencesdependent on alcohol and difficult to control its consumption. On the other hand, excessive alcohol consumption in the long term can cause disturbances in brain performance, including disturbances in memory, attention, coordination, and locomotion. How does alcohol affect the functioning of nerve cells and the central nervous system? What is the mechanism that occurs? Based on information from the literature, analyze what will happen to coordination and locomotion in someone who is addicted to alcohol and consumes large amounts of alcohol over a long period of time.

- An action potential is an all-ornone event. This on/off signaling is an evolutionary adaptation of animals that must sense and act in a complex environment. It is possible to imagine a nervous system in which the action potentials are graded, with the amplitude depending on the size of the stimulus. Describe what evolutionary advantage on/ off signaling might have over a graded (continuously variable) kind of signaling.arrow_forwardA neuron of the median giant fiber of an earthworm would respond to an increased intensity of a stimulus by: Increasing the amplitude of action potentials generated Increasing its resting membrane potential Increasing the frequency of action potentials generated Increasing the conduction velocity of action potentials generatedarrow_forwardMatch 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 cnidariansarrow_forward
- Imagine your hand accidentally touching a cholla cactus. Receptors in the skin result in signals sent through [ Select ] These neurons are [ Select ] V in structure, and are part of the [ Select ] v division of the [ Select ] nervous system. Ultimately the signal reaches the brain for processing, and the brain may command the hand to pull back from the painful stimulus. [ Select ] which are [ Select ] in structure, send signals through the [ Select ] division of the peripheral nervous system. The [ Select ] are skeletal muscle cells that will contract, resulting in the hand pulling away from the cactus.

- Distinguish between innate and learned behavior. Explain how an experiment using optogenetics could demonstrate the concept of “fire together, wire together” Predict whether a given change in receptors or neurotransmitter release is likely to strengthen or weaken a synaptic connection. Hypothesize how a channel or another molecule in a plant or animal would detect outside stimuli such as touch, chemicals, or light. Predict how perturbations in light levels, retinal, opsins, and cation channels in photoreceptors affects the photoreceptor’s membrane potential and neurotransmitter release. Given information about a neuron’s responses to stimuli, hypothesize what its receptive field might be.arrow_forwardDescribe the evolutionary changes in nervous systems.

- 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.arrow_forwardIn the disease myasthenia gravis, the human body makes—by mistake— antibodies to its own acetylcholine receptor molecules. These antibodies bind to and inactivate acetylcholine receptors on the plasma membrane of muscle cells. The disease leads to a devastating progressive weakening of the people affected. early on, they may have difficulty opening their eyelids, for example, and, in an animal model of the disease, rabbits have difficulty holding their ears up. As the disease progresses, most muscles weaken, and people with myasthenia gravis have difficulty speaking and swallowing. eventually, impaired breathing can cause death. explain which step of muscle function is affected.arrow_forwardHow would your nervous system respond if you encounter a snake on a hiking trail? Group of answer choices 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 system would send signals to the somatic nervous system to increase respiration and heart rate.arrow_forward
