In UMN lesions the response of the paralyzed muscles to electrical stimulation is :-a- exaggeratedb- inhibitedc- not changedd- is absent

Please label 1-6 with the correct name from the jotted list.

Increased sensory discharge from muscle spindles :-a- decreases muscle toneb- increases muscle tonec- could either increase or decrease muscle tone according to the muscle affectedd- has no effect on muscle tone

A Na+ 10 msec B 40mV Ca²+ C Na+ Ca²+ Each graph represents the depolarization activity during an action potential in Xenopus spinal cells at different stages of development. Referring to each electrical reading (A, B, and C), place the graphs in order of developmental stage, from earliest to latest. What are the major changes in action potential activity that occurs with development?

Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. 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. Be detailed in your explanation

Nerve impulses are sent bidirectionally. True O False

Please label the following (1-9). Terms include: dendrite of motor neuron, axon terminal of motor neuron, dendrites of sensory neuron, axon terminal of sensory neuron.

What are some typical channelopathies that affect neurons? Please, answer on your own words, no copy or paste, thank you.

The highly localized nature of stretch reflex is due to :-a- the limited number of interneurons in the reflex pathwayb- all the central ends of afferents from spindles of the stretched muscle terminate on the α -motor neurons of the musclec- the α -motor neurons of the stretched muscle receive most of the central terminals of afferents coming from spindles of the muscled- activation of inhibitory interneurons which inhibit the motor neurons ofthe surrounding muscles
