Part ACarpal 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 carpaltunnel 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.SubmitRequest AnswerProvide Feedback< Return to Assignment

Bell’s Palsy affects the facial nerve and most often presents with motor symptoms only. Yet the facial nerve is a mixed sensory nerve; suggest possible reasons for this anomaly.
When a patient needs a tendon graft, surgeons sometimes use the tendon of the palmaris longus, a relatively dispensable muscle of the forearm. The median nerve lies nearby and looks very similar to this tendon. There have been cases in which a surgeon mistakenly removed a section of this nerve instead of the tendon. What effects do you think such a mistake would have on the patient?
Inhibitory interneurons associated with the reflex arc are turned on by glutamate. Group of answer choices True False The tendon tap reflex can be elicited by a stretch in a muscle. What is the order of information flow from the primary sensory afferent to the lower motor neuron? Group of answer choices dorsal horn, dorsal root, ventral horn dorsal root, dorsal horn, ventral horn ventral root, ventral horn, dorsal horn, dorsal root In regards to the spinothalamic tract, where does the second order neuron cross midline? Group of answer choices at the spinal cord segment at the brainstem at the thalamus it never crosses midline
Walter has a spinal cord injury. Dermatome testing shows that he has no feeling below his waist on his left side. Myotome testing shows he has complete movement throughout his body on both sides. What part of the spinal cord is likely injured?
Sin Young incorrectly classified proprioception as general somatic motor because it refers to the innervation of muscles. Actually, proprioception is general somatic sensory. Explain why.
Some types of epilepsy are treated by placing an electronic deviceinside the neck to stimulate the vagus nerve. Minor injury to the vagusnerve during implantation of the device can lead to hoarseness. Why isthis so? Can you predict two other consequences of minor injury to thevagus nerve?
Carpal tunnel syndrome is a modern medical problem created by repetitive tasks such as keyboarding on computers or doing assembly line work. in this condition nerves in the wrist may become pinched, producing irritating, tingling sensations in the hands and lower arms. a) what is the source of the tingling
Which of the following is false regarding nerve plexuses? A) Nerve plexuses occur in the cervical, brachial, lumbar and sacral regions. B) Nerve plexuses involve only the dorsal rami. C) Nerve plexuses are interlacing nerve networks, so that each branch of a plexus contains fibers from several spinal nerves. D) Because of nerve plexuses, each muscle in a limb receives its nerve supply from more than one spinal nerve. E) Because of nerve plexuses, damage to a single spinal segment or root cannot completely paralyze any limb muscle. In a spinal reflex, integration occurs in the cerebral cortex in the brain stem in the thalamus in the spinal cord in the cerebellum True or false.

your patient, Mr. Pratchett, is unable to open his eyelid. on examination, you find that his pupil is dilated, and he is unable to move his affected eye in any direction except laterally and downward, indicating that only his lateral rectus and superior oblique extrinsic eye muscles are functioning. based on this information, which cranial nerve do you think is involved in Mr. Pratchett's condition? explain your reasoning
