- 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?Match somatic and autonomic nervous divisions with their desscriptions. can be boluntary 1. somatic fairly involutary 2. autonomicAUTONOMIC NERVOUS SYSTEM STRUCTURE FUNCTION(S)/CHARACTERISTIC(S) SYMPATHETIC DIVISION 1 Preganglionic neuron 2 Postganglionic neuron 3 Gray horns of the spinal cord 4 Dorsal Roots of the spinal cord 5 Ventral Roots of the spinal cord 6 Dorsal Rami 7 Ventral Rami 8 White ramus communicans 9 Gray ramus communicans 10 Sympathetic trunk ganglion (Paravertebral ganglia) 11 Superior cervical ganglion 12 Middle cervical ganglion 13 Inferior cervical ganglion 14 14a 14b 14c Prevertebral ganglia Celiac ganglion Superior mesenteric ganglion Inferior mesenteric ganglion PARASYMPATHETIC DIVISION 15 Preganglionic neuron 16 Postganglionic neuron 17 CN III Oculomotor nerve 18 CN VII Facial nerve…

- A patient with a cerebral lesion exhibits loss of fine motor control ofthe left hand, arm, forearm, and shoulder. All other motor and sensoryfunctions appear to be intact. Describe the location of the lesion asprecisely as possibleClassify the following characteristics to demonstrate your knowledge of differences between the sympathetic and parasympathetic divisions of the autonomic nervous system. Sympathetic Nervous System Most ganglia lie close to the spinal cord and form two chains of ganglia-one on each side of the spinal cord Increases intestinal motility and stimulates intestinal secretion Postganglionic axons are generally short Preganglionic axons are generally short Postganglionic axons release NE that binds to adrenergic receptors located on the effectors Decreases heart rate, contractility, and conduction velocity Ganglia lie within, or very close to, innervated organs Decreases intestinal motility and inhibits intestinal secretion Long preganglionic axons release ACh that binds to nicotinic receptors located within the ganglia Neurons leave the CNS from the thoracic and lumbar regions of the spinal cord Parasympathetic Nervous System Generalized activation is called the fight-or-flight response…AUTONOMIC NERVOUS SYSTEM STRUCTURE FUNCTION(S)/CHARACTERISTIC(S) SYMPATHETIC DIVISION Preganglionic neuron Postganglionic neuron Gray horns of the spinal cord Dorsal Roots of the spinal cord Ventral Roots of the spinal cord 1 3 4 6.

These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited. Be sure to include the phases of an action potential, the channels involved, and the importance of an action potential.
