- Brodmanns areas map different regions of the ________ to particular functions. cerebellum cerebral cortex basal forebrain corpus callosumWatch this video (http://openstaxcollege.org/l/motorpathway) to learn more about the descending motor pathway for the somatic nervous system. The autonomic connections are mentioned, which are covered in another chapter. From this brief video, only some of the descending motor pathway of the somatic nervous system is described. Which division of the pathway is described and which division is left out?A(n)______neuron has one axon and one____ dendrite extending directly from the cell body. unipolar bipolar multipolar pseudounipolar
- Watch this video (http://openstaxcollege.org/l/basalnuclei2) to learn about the basal nuclei (also known as the basal ganglia), which have two pathways that process information within the cerebrum. As shown in this video, the indirect pathway is the longer pathway through the system that results in decreased activity in the cerebral cortex, and therefore less motor activity. The indirect pathway has an extra couple of connections in it, including disinhibition of the subthalamic nucleus. What is the end result on the thalamus, and therefore on movement initiated by the cerebral cortex?The cells have highly branched dendrites make more connections than any other type of neuron. They are found in great abundance in the cerebellum. O multipolar bipolar O stellate O PurkinjeRegeneration of a severed axon has a better chance forsuccess in the PNS than in the CNS. Why is regeneration inthe CNS less likely to succeed?
- Part D- Organization of the Sympathetic Nervous System The divisions of the autonomic nervous system are distinctly organized. Place the term into the bin that best describes its location. • View Available Hint(s) Reset Help Short preganglionic fiber Long preganglionic fiber Long postganglionic fiber Chain ganglia Thoracolumbar origins Vagus nerve (CN X) Ganglia within target tissue Pelvic nerves Sympathetic division Parasympathetic division SubmitThe giant axon of the squid (Figure Q11–3) occu-pies a unique position in the history of our understandingof cell membrane potentials and nerve action. When anelectrode is stuck into an intact giant axon, the membranepotential registers –70 mV. When the axon, suspended in abath of seawater, is stimulated to conduct a nerve impulse,the membrane potential changes transiently from –70 mVto +40 mV.The highly branched structures of neurons wouldseem to make it almost inevitable that they should makeunproductive synapses with themselves, yet they manageto avoid this outcome very effectively. How is this accom-plished in vertebrates?
