What are medullated and non- medullated nerve fibres?
Depending on the number of sheaths ,nerve fibres are of two types :-Myelinated (Medullated) Nerve Fibre.Nonmyelinated (NonMedullated) Nerve Fibre.Myelinated (Medullated) Nerve Fibre.:-are those nerve fibres which are covered by two sheaths ,myelin & neurolemma.Nonmyelinated (NonMedullated) Nerve Fibre.:-these nerve fibres are devoid of myelin sheath .However,neurolemma is present.

What is the function of the medial nerve?
The median nerve provides sensory and motor function to the hand and forearm. It innervates muscles involved in flexion of the wrist and fingers, as well as sensation to the palm and fingers. Injury to the median nerve can result in weakness, numbness, and tingling in the hand and fingers.
Why the transmission of nerve impulse is faster in medullated nerve fiber than in non-medullated nerve fiber?
generally the impulse is nothing but the stimulus carried to a part of body to carry out specific action in response to that stimulus.it is transmitted from one neuron to another or one neuron to another organ.this is carried all along the neuron and at the end that is at the synapse it gets diffused in neurotransmitter and again transmitted to another organ or neuron.this is carried very faster.this is started polarization of neuron and once polarized and being transmitted it cant be again polarizedthis occurs even more fastly in .mylenated neurons than in nonmylenated.bec in mylenated neurons the axon is partly covered by myleinshreath.this myleinshreath has a special property that it doesn't allow ions to pass through it.since polarization is occurred due to movement of ions in and out of axons,and the mylein shreath doesn't allow this the leaping of ions occurs.and as a result impulse been transmitted as a loop of current by taking leap at mylein shreath.while in nonmylenated ones no such leaping occurs and it is transmitted slowly all along the length of axon.so impulse transmission occurs very fast in mylenated ones.
An inability to extend the leg would result from a loss of function of what nerve?
An inability to extend the leg would result from a loss of function of the common peroneal nerve, a branch of the sciatic nerve. This nerve provides motor function to the muscles that extend the leg and dorsiflex the foot. Injury or compression of the common peroneal nerve can lead to weakness or paralysis in these muscles, resulting in difficulty extending the leg.

What is the function of a Krause Corpuscle?
The main function of a Krause Corpuscle is sensory. It is small oval capsule that is in the medullated fibers in connective tissue. It helps with sensations in nerve-based organs like the eyes, parts of the reproductive systems, some joint synovial membranes, nerve trunks, and facial mucous membranes.

List the reasons for performing a peripheral nerve functions assessment?
A peripheral nerve function test is performed to test the nerve function in the peripheral nerve. This test is often performed to when there is pain or weakness in the limbs.
