Neonatal Autonomic, Motor, Sensory, and State Regulation, Fetal and Extra-Uterine Adaptation, Primitive Reflex Pathways, Neuromuscular and Sensory Maturation, APGAR and Ballard Assessments, Myelination, CNS Development, Neural Tube Defects, Anencephaly, Encephaloceles, Spina Bifida Occulta, Spina Bifida Cystica, Meningocele, Myelomeningocele, Hydrocephalus Etiology and Characteristics, Chiari Malformations I-IV, Cerebral Palsy: Pyramidal and Extrapyramidal Types, Dyskinetic and Ataxic CP, Pediatric Seizures: Partial, Generalized, Absence, Infantile Spasms, Febrile Seizures, Pediatric Epilepsy, Headaches in Children, Viral and Bacterial Pediatric Meningitis, Risk Factors, Clinical Manifestations, CNS Injury and Developmental Delay Exam Questions Verified and Provided with Complete A+ Graded Rationales Latest Updated 2026 Autonomic Nutrient intake from placenta to oral (external) - periodic vs continuous, hunger, thirst and satiety cues regulate intake Fetal temp is regulated Motor Skeletal muscle active in fetus Movement transitions from limited and protected Amniotic fluid reduces effects of gravity Gravity is a major factor in movement of the neonate Extra-uterine life: must now exert energy for movement Sensory Change in sensory experience at birth - contractions produce pressure changes, pressure change with vaginal birth, possible discomfort Uterus is dark vs light in extra-uterine environment Uterine environment is warm vs sensation of cold in extra-uterine environment Sounds heart in-utero include mother's heartbeat - rhythmic and constant, external sounds muted Touch (hands, clothing), taste, sounds, odors, visual stimuli State regulation Sleep/wake patterns Mostly influenced by caregivers sensory and motor function The neonate's brain continues to develop connections between neurons and myelination also continues Immature sensory function is reflected in motor movement Infant/primitive reflexes - indicator of age/development of nervous system, information about muscle tone and motor function Neuromuscular and sensory development CNS is earliest to develop and last to completely mature - neural plate, neural fold, neural tube (by 28 days) Most common anomalies of CNS occur due to failure of proper neural tube closure or insult to neural tube - neural tube defects (NTD) - vertebral, meningeal, vascular, dermal structures APGAR score appearance, pulse, grimace, activity, respiration Neonatal assessment - 1 min and 5 min after birth, in each of the 5 categories your baby is scored on a 0-2 scale Ballard Six evaluations of the neonate's neuromuscular system Posture - how the baby holds his or her arms or legs Square window - how far teh baby's hands can be flexed toward this wrist Arm recoil - how far the baby's arm "spring back" to a flexed position Popliteal angle - how far the baby's knees extend Scarf sign - how far the elbows can be moved across the baby's chest Heel to ear - how close the baby's feet can be moved to the ears A score is assigned to each assessment area Typically, the more neurologically mature the baby, the higher the score Primitive reflex pathways Require myelination - a process where lipid/protein material covers the axons of neurons, permitting electrical signals to travel more quickly By 6 mos of age the primitive reflexes are inhibited and progress to voluntary movement and disappear in a predictable order Abnormal persistence of infant/primitive reflexes suggests developmental delays or CNS lesions Asymmetric responses may indicate lesions in the motor cortex on the opposite side Reflexes (infant assessment) Asymmetrical tonic neck Moro Palmer grasp Plantar grasp Rooting Stepping Sucking
