Question

The type of neuron associated with numbness and tingling is the:

A. Afferent neuron

B. Efferent neuron

C. Association neuron

D. Neurotransmitter

4. A young woman arrives in the emergency department complaining of severe abdominal and back pain. After a battery of tests, it is determined that the woman is pregnant and in labor. She denies knowledge of the pregnancy, and therefore has received no prenatal care. An ultrasound is performed to determine the approximate gestational age of the infant. The ultrasound shows a child of approximately 29 weeks’ gestation with an apparent posterior neural tube defect. An absence of amniotic fluid is evident, suggesting a prior rupture of membranes. Because of the defect and a possible risk of infection, the team advises the mother to deliver the child via cesarean section as soon as possible. After delivery, the child is taken to the neonatal intensive care unit, where the infant is evaluated and cared for. The child is diagnosed with a thoracic myelomeningocele and is surgically repaired within 24 hours of delivery.

1. In addition to this defect, the infant is at an increased risk of:

A. Chiari II malformation

B. Craniosynostosis

C. Cortical dysplasia

D. Cerebral arteriovenous malformations

2. Within the next week, the infant is noted to have seizure like activity. The most likely cause of the seizure would be:

A. Infantile spasms

B. Febrile seizures

C. Juvenile myoclonic epilepsy

D. Infection

Answer 1

The type of neuron associated with numbness and tingling is the:

A. Afferent neuron

B. Efferent neuron

C. Association neuron

D. Neurotransmitter

Answer: A. Afferent neuron

They are the sensory neurons which carry impulses from peripheral system to central nervous system

1. In addition to this defect, the infant is at an increased risk of:

A. Chiari II malformation

B. Craniosynostosis

C. Cortical dysplasia

D. Cerebral arteriovenous malformations

Answer A: Chiari II malformation

Chiari II malformation is associated with neural tube defects

2. Within the next week, the infant is noted to have seizure-like activity. The most likely cause of the seizure would be:

A. Infantile spasms

B. Febrile seizures

C. Juvenile myoclonic epilepsy

D. Infection

Answer D. Infection

The most likely complication after myelomeningocele repair is Infection and which can cause the seizure in newborns.
