Document Summary

Tongue retraction: superior longitudinal + inferior longitudinal. Tongue retraction: anterior bers of the genioglossus. Tongue protrusion: posterior bers of the genioglossus. Palatoglossus: pharyngeal plexus of cn xi accessory nerve and cn x vagus nerve. Palatoglossus is more of a velum muscle so it is innervated by the nerve that innervate the velum. Palatal muscles: cn xi accessory nerve and cn x vagus nerve. Except! tensor veil palatini cn v trigeminal. Pharyngeal muscles: cn xi accessory nerve and cn x vagus nerve. An infant will meet their basic need through gross re exive movements in reaction to environmental stimuli. These primitive patterns will develop into the infant"s voluntary control of trunk, neck and limb movement. An infant will begin to develop motor control through gross movement that undergoes re nement over time. Re nement occurs from head to tail (cephalocaudally) and from medial to distal structures (proximodistally)
