A posterior root contains A) sensory axons only B) motor axons only C) a mix of sensory and motor axons D) autonomic nervous system axons - correct answer A) sensory axons only The white matter of the spinal cord is surrounded by gray matter. A) True B) False - correct answer B) False If a patient experiences numbness in the boundaries of a dermatome, it is suggestive of damage to A) the somatosensory cortex B) the thalamus C) one of the spinal funiculi D) the anterior h...

Simple Reflexes correct answer: Sensory neurons make synapses with spinal cord motoneurons to mediate simple reflexes. This is the simplest form of motor control Central Pattern Generators correct answer: Networks of interneurons in the spinal cord and brainstem coordinate the interactions of many groups of motor groups. Works for things such as breathing, flying, etc. Produces a rhythmic pattern output. Complex / Volitional Movement correct answer: Motor output that is planned and refi...

NBME 13progressive weakness, dec strength, hand muscle atrophy, diffuse hyperreflexia and fasciculations on hands and arms, normal sensory exam; - correct answer amyotrophic lateral sclerosis (ALS) --death of both upper and lower motor neurons in the motor cortex of the brain, the brain stem, and the spinal cord --Stephen Hawking disease --*UMN and LMN signs* --rapidly progressive weakness with fasciculations eventually leading to muscle atrophy, spasticity, dysarthria, dysphagia, respirato...
