Question

bio1130 exam 3 - chapters 10 and 11 nervous syst... every neuron has which of the following components? multiple choice many axons myelin a neurilemma a cell body

Explanation:

• Neurons have a cell body (soma) as a fundamental component.
• "Many axons" is incorrect as most neurons have one axon.
• "Myelin" is a sheath around some axons, not all neurons have myelin (e.g., unmyelinated neurons).
• "A neurilemma" is the outer layer of Schwann cells in myelinated neurons, not all neurons have it (e.g., oligodendrocyte - myelinated neurons in CNS lack neurilemma). So every neuron has a cell body.

Answer:

A. A cell body
