Definition
| involuntary movement reactions elicited by such forms of sensory stimuli as sound, light, touch, or body position |
|
|
Term
| What are the 2 purposes of reflexes? |
|
Definition
- survival
- strengthening for future
|
|
|
Term
|
Definition
| primarily associated with the infant's instinct for survival and protection |
|
|
Term
|
Definition
| provide the infant with the ability to react to gravitational forces and changes in equilibrium |
|
|
Term
|
Definition
| resemble later voluntary locomotor movements |
|
|
Term
|
Definition
| used throughout lifespan to evaluate neuromuscular response (jaw, knee, biceps, ankle) |
|
|
Term
|
Definition
| protruding lips elicited by anything that touches its lips |
|
|
Term
| rooting reflex AKA search reflex |
|
Definition
| resonse to seek food; activated by a light touch on the cheek, which causes the newborn to turn its head in search of nourishment |
|
|
Term
|
Definition
| when the newborn is startled or begins to fall, its arms and legs extend outward, hands open and fingers spread |
|
|
Term
|
Definition
| evident when a small rod or someone's finger touches the newborns palm; the fingers (excluding the thumb) fold tightly around the object with a grasping action |
|
|
Term
|
Definition
asymmetric- place on back and turn neck side to side; neck stretch triggers tone increase in limbs; as the limbs extend on the side of the body in which the head is facing and flex on the opposite side
symmetric- tip head back: arms extend and legs flex; tip head forward: arms flex and legs extend |
|
|
Term
| Babkin reflex/palmar-mandibular reflex |
|
Definition
| elicited by providing pressure simultaneously to both palms, which causes the infant to exhibit all or one of the following behaviors: mouth opens, eyes close, neck flexes, and head tilts forward |
|
|
Term
|
Definition
| stroke on bottom of foot, infant fans out and extends its toes |
|
|
Term
|
Definition
| stroke infant's sole of foot, toes contract or flex as if attempting to grasp the object |
|
|
Term
|
Definition
| elicited by gently turning the infants body in either direction while on back, the baby will respond by turning its head in the same direction |
|
|
Term
|
Definition
| elicited by turning the head in one direction while the infant is in a supine position, the body will reflexively right itself by turning in the same direction- first the hips and legs and then the trunk |
|
|
Term
| labryinthine righting reflex |
|
Definition
- maintain upright body posture/contribute to the ability to move in a forward direction
- can be elicited by holding infant in an upright position and tilting its body forward, backward or to the side; in response, the infant will reflexively attempt to maintain an upright postures of the head by moving it in the direction opposite that in which the trunk was moved
- prepares the baby for movements of rolling over, crawling on all fours, standing and walking.
|
|
|
Term
|
Definition
- involuntary attempt to maintain an upright position
- elicited by placing infant in an upright sitting position while holding its hands and carefully tipping forward or backward; in response, the infant will flex or extend its arms in an apparent effor to maintain the upright posture
|
|
|
Term
|
Definition
| when pressure is applied to the sole of on foot or both alternately, the infant will reflexively crawls using its arms and legs |
|
|
Term
|
Definition
| elicited by holding the infant upright with the feet touching a flat surface; pressure on the bottom of the infants feet will cause it to reflexively respond with crude by characteristic walking movements |
|
|
Term
|
Definition
| variation of stepping response where infant's foot lightly comes in contact with the edge of the table and responds by appearing to place foot on the table |
|
|
Term
|
Definition
| can be elicited by holding the infant horizontally in the water with its head up or over the surface and the infant responds by moving the arms and legs rhythmically in a swimming movement pattern |
|
|
Term
|
Definition
| theoretical view that stimulation of the reflex will positively affect later voluntary control |
|
|
Term
|
Definition
| belief that increased stepping frequency and the earlier onset of independent walking may simply be the result of strengthening the infants musculature |
|
|
Term
|
Definition
| or stereotypies, are stereotypic repetitive motions that appear in the absence of any known stimuli |
|
|
Term
|
Definition
| occurs in the phase of motor development that spans the period from birth to approximately 2 years of age. As the infant's nervous system matures, a gradual increase in basic voluntary motor behavior occurs |
|
|
Term
|
Definition
| the infants purposeful efforts at prone locomotion, which normally occurs between the ages of 6-8 months. Infants crawl using their arms and legs to drag the body along a surface |
|
|
Term
|
Definition
| 8-10 months, involve moving in a prone position on hands and knees with the abdomen clear of the surface |
|
|
Term
|
Definition
| movement by means of shifting weight from one foot to the other, with at least one foot contacting the surface at all times |
|
|
Term
|
Definition
| the intitial voluntary use of the hands as characterized by seizing or grasping |
|
|
Term
|
Definition
| refers to skillful use of the hands, such as in stringing beads or threading a needle |
|
|
Term
|
Definition
| encompasses both descriptors by referring to the developmental characteristics of hand movements |
|
|
Term
|
Definition
| although the human body has paired limbs and sensory organs, we use them in an asymmetric manner. |
