A 17-year-old boy fell from his motorcycle and complains of numbness of lateral pa of the arm. Examination reveals the axillary nerve is severed. Which of the following types of axons is most likely spared? 
Select and explain. 
A. Postganglionic sympathetic axons, B. Somatic afferent axons, C. Preganglionic sympathetic axons, D. General somatic efferent axons
C: Preganglionic sympathetic axons
Answer: C: Preganglionic sympathetic axons 
Explanation: The axillary nerve contains no preganglionic sympathetic general visceral efferent (GVE) fibres, but it contains postganglionic sympathetic GVE fibres. It also contains general somatic afferent (GSA), general somatic efferent (GSE), and general visceral afferent (GVA) fibres.
