Which of the following statements is correct when a cockroach makes the decision to begin walking? a. The subesophagael ganglion disinhibits specific regions in the frontal ganglion of the stomatogastric nervous system, which allows the frontal ganglion to excite the GPGs for flexing and extending the legs in the caudal ganglion. b. The protocerebrum disinhibits specific regions of the subesophageal gangion, which in turn excite the command interneurons that activate the Flexor Burst Generators and inhibit the Extenor Motor Neurons in the thoracic ganglion that control each leg. c. The subesophageal ganglion disinhibits the Central Body in the protocerbrum of the centeral nervous system, which excites the CPGs for the legs contained within the abdominal ganglion. d. The pars intercerebralis of the protocerebrum releases EDNH, which excites the GPGs for the legs contained within the thoracic ganglia.

Do you think the patellar reflex would be inhibited or enhanced by actively contracting the quadriceps muscle group? With an understanding of how muscle spindle fibers work, explain how active contraction of a muscle might affect the myotactic reflex. [hint: try to elicit a knee jerk reflex when someone is doing a leg lift]
Sensory neurons transmit information towards the central nervous system. Which of the following is true concerning the movement of peripheral- information towards the central nervous system? A. Dendrites of the sensory neurons synapse with interneurons of the spinal cord. B. Axons of the sensory neurons synapse with motor neurons of the muscles involved in the spinal reflex. C. Axons of the motor neurons synapse with the interneurons of the spinal cord. D. Axons of the sensory neurons synapse with the interneurons of the spinal cord.
Benign Paroxysmal Positional Vertigo is a disorder where some of the calcium carbonate crystals in the utricle migrate into the semicircular canals. Why does this condition cause periods of dizziness? a. The hair cells in the semicircular canals will be constantly activated. b. The hair cells in the semicircular canals will now be stimulated by gravity. c. The utricle will no longer recognize acceleration. d. There will be too much volume in the semicircular canals for them to detect motion.
What aspect of the neural circuity in the pupillary light reflex is responsible for the consensual response? a. Preganglionic parasympathetic neurons project their axons to neurons in the ciliary ganglion. b.Pretectum neurons send axons to the Edinger-Westfall nuclei on both sides of the brain. c. Neurons in the ciliary ganglion innervate the constrictor muscle in the iris, which decreases the diameter of the pupil when activated. d. The muscles in the iris encircle the pupillary opening so that light enters in the center of the eye. e. The ciliary muscles contract concentrically to release the tension in the zonule fibers.
The first relay in the brain for nerves carrying taste information is: a. the cerebral cortex b. the hypothalamus c. the orbital prefrontal cortex d. the nucleus of the solitary tract A single action potential in a somatic motoneuron produces a twitch in the muscle it innervates. Generation of sustained contraction is a product of that motoneuron producing multiple action potentials. What is a term used to describe this phenomenon? a. Stretch reflex b. Temporal summation c. Spatial summation d. Muscle fatigue
Part A Carpal tunnel syndrome is a condition in which the median nerve is compressed as it travels through a narrow passage in the wrist. Explain how hand dynamometry might be used to assess a patient's need for surgery to release carpal tunnel compression. O Hand dynamometry measures electrical activity of the median nerve, which will be reduced if the median nerve is compressed. O Hand dynamometry measures grip strength, which will be reduced if the median nerve is compressed. O Hand dynamometry measures grip strength, which will be increased if the median nerve is compressed. O Hand dynamometry measures electrical activity of the median nerve, which will be increased if the median nerve is compressed. Submit Request Answer Provide Feedback < Return to Assignment
