which of the following is not correct concerning nerves?
sensory nerves contain cell bodies.
nerves are covered by an outer connective tissue sheath called the epineurium.
nerves are analogous to tracts in the cns.
nerves are collection of axons of either sensory or motor neurons but not both.

Explanation:

To solve this, we analyze each option:

1. Sensory nerves (like dorsal root ganglia) have cell bodies, so this is correct.
2. Nerves have an outer connective tissue sheath called epineurium, so this is correct.
3. Nerves (PNS) and tracts (CNS) are both collections of axons, so they are analogous, correct.
4. Nerves can be mixed (contain both sensory and motor axons), so the statement "Nerves are collection of axons of either sensory or motor neurons but not both" is incorrect.

Answer:

The option "Nerves are collection of axons of either sensory or motor neurons but not both" (the last option in the list of choices)
