Explanation Characters: Spinal cord Spinal nerves Genital organs Central nervous system To explain, reason for a young man met with a motorcycle accident that severed his spinal cord at his neck and leaves him paralyzed from the neck down. His wife asks the physician whether her husband can have penile erection. A young man met with a motorcycle accident that severed his spinal cord at his neck and leaves him paralyzed from the neck down. His wife asks the physician whether her husband can have penile erection and whether it is possible for him to father any children. What should the doctor tell her? Explain your answer. Penile erection is a physiological phenomenon in which the penis gets erected due to visual perception, touch, and sexual arousal. It is triggered by the parasympathetic division of autonomic nervous control of the sacral spinal nerves of S1, S2 and S3. A young man met with accident damaging his spinal cord and his spinal nerves were severed, making him completely paralyzed below the neck. Penile erection is brought on by the dilation of deep arteries in the penis by nitric oxide...

Summary Introduction

Summary:

The spinal cord is an important part of the central nervous system from where the spinal nerves emerge and innervate most of the organ systems from the neck to the limbs. Genital organs in human male and female reproductive systems are innervated by the pelvic splanchnic nerves which arise as sacral nerves from the spinal cord as S2, S3, and S4. These nerves control the motor functions of the genital organs.
