How is a severed electrical cord similar to a nerve that has been cut?
Homework Answers
Nerves carry messages from one part to another part of the body in the form of electrical signals.They are specialized cells which stimulate other cells in our body to transfer information.
In electric system electricity is transferred by the means of sending signals by the conduction wire.If the electric card is severed it cannot transmit electricity.
Axon receives impulse if the axon is cut then the impulse cannot be transferred the message because it cannot reach another neuron.Thus nerve impulse cannot transmit the message.
So like severed electric cannot transmit energy,nerve cannot be able to transmit the message

1) If the musculocutaneous nerve is severed, is elbow flexion still possible? Why? 2) What motions of the elbow would be hindered if the ulnar nerve were severed? 3) Tennis elbow is caused from inflammation of the tendons on the lateral epicondyle. Describe what repetitive movements cause this condition and explain why tennis elbow is not actually an elbow injury. 4) If the median nerve is impinged at the elbow, what will be the resulting motor deficits? Is finger flexion...

The speed of propagation of the action potential (an electrical signal) in a nerve cell depends (inversely) on the diameter of the axon (nerve fiber). If the nerve cell connecting the spinal cord to your feet is 1.3 m1.3 m long and the nerve impulse speed is 18 m/s18 m/s , how long does it take for the nerve signal to travel the distance?

4. This figure (part a) shows a segment of the ventral nerve cord of the crayfish (which is analogous to our spinal cord). The lateral giant nerve fiber runs down this nerve cord and passes a signal to the motor giant neuron, which triggers muscle contraction in a tail flip escape response. Look at the neural recording that is shown (part b). It shows the presynaptic action potential of the lateral giant neuron and the postsynaptic action potential of the...

An electrical power line connecting Miami to Key largo which is 48 miles long has been cut at some random point so that the distance between the cut-point from Miami, X, can be assumed to have a uniform distribution. Find the probability that distance between the cut-point and Miami is more than 4 times the distance between the cut-point and the key Largo.

How could an embryonic stem cell be used to repair a severed spine? A. Embryonic stem cells secrete proteins that repair all other cell types, including nerve cells. B. Embryonic stem cells can cause any other cell type to multiply. C. Embryonic stem cells are primarily involved with neural growth and development. D. Embryonic stem cells can grow into any other cell type, including a nerve cell.
