cephalocaudal การใช้

• Sexual reproduction involves a cephalocaudal association.
• The cephalocaudal trend is also the trend of infants learning to use their upper limbs before their lower limbs.
• There is a genetic cephalocaudal ( head-to-foot ) trend in both prenatal and postnatal development.
• In addition to motor deficits, adult Dab1-scm mutants are characterized by anomalies in grooming behavior, in particular shorter grooming bouts than non-ataxic controls of the same background strain, though they display the normal cephalocaudal sequence of grooming anterior body parts ( face washing and forelimb licking ) prior to posterior parts . Dab1-scm mutants are also characterized by reduced spontaneous alternation rates and deficits in visuomotor control while swimming towards a visible platform.
