The first energy level in an atom can hold how many atoms?   The first shell of an atom can hold 2 electrons. This does not mean that all atoms do have 2 electrons in their first shell. The exception is hydrogen (atomic number = 1 â¦) which has only 1 electron in its first shell before reacting with other atoms.
Chronic idiopathic axonal polyneuropathy is an insidiously progressive sensory or sensorimotor polyneuropathy (a neurological disorder that occurs when many peripheral nerves throughout the body malfunction simultaneously).hronic idiopathic axonal polyneuropathy is an insidiously progressive sensory or sensorimotor polyneuropathy (a neurological disorder that occurs when many peripheral nerves throughout the body malfunction simultaneously).
Sensory polyneuropathy is the condition of having multiple sensory neuropathies, while motor polyneuropathy refers to multiple motor neuropathies. Sensorimotor polyneuropathy or sensory-motor polyneuropathy is the combination of both conditions. Myelinopathy, or demyelinating polyneuropathy, is due to a loss of myelin (or of the Schwann cells that make and contain it). 2  This demyelination slows down or completely blocks the conduction of action potentials through the axon of the nerve cell.
