FLHD 1500 EXAM 2 QUESTIONS AND ANSWERS
Norms - CORRECT ANSWER✅✅an average, or standard, for a particular population
Age 1- 22 lbs, 30 inches
Age 2- 30 lbs, 32-36 inches
body changes - CORRECT ANSWER✅✅At birth a baby weighs 7 lbs, the weight of the baby triples by 12
months
From birth to age 2 the baby height increases by a foot
headsparing - CORRECT ANSWER✅✅a biological mechanism that protects the brain when malnutrition
disrupts body growth. The brain is the last part of the body to be damaged by malnutrition
Brain maturation - CORRECT ANSWER✅✅During the first months and years, rapid growth and
refinement in axons, dendrites, and synapses occur, especially in the cortex. Brain weight triples from
birth to 2 years.
myelination - CORRECT ANSWER✅✅branching, networking,and coating nerves with myelin and enables
faster brain impulses increased efficiency
Pruning - CORRECT ANSWER✅✅the process by which unused connections in the brain atrophy and die
basic brain structures - CORRECT ANSWER✅✅Neuron- nerve cell, billions in the CNS
Cortex- the outer layers of the brain
Axon- a neuron fiber, transmits to dendrites
Dendrite- a neuron fiber, receives impulse from axon
Synapse- intersection between axon of one neuron and dendrites of other neurons
Neurotransmitter- brain chemical, carries information between neurons
sensation - CORRECT ANSWER✅✅the response of a sensory system (eyes, ears, skin, tongue, nose)
when it detects a stimulus
, perception - CORRECT ANSWER✅✅the mental processing of sensory information when the brain
interprets a sensation
reflexes - CORRECT ANSWER✅✅Critical
1. Maintain oxygen supply
Breathing, hiccups, sneezes
2. Maintains body temperature
Cry, shiver, tuck legs
3. Manage feeding
Sucking, rooting, swallowing
Non-Critical
1. Babinski- stroke foot and toes fan out or curl
2. Stepping- hold vertical and feet move or step
3. swimming- place on stomach, acts like swimming
4. grasping- place object on palm, fingers wrap
5. moro- false drop or startle and arms and legs flail
fine motor - CORRECT ANSWER✅✅small body movements
-especially hands and fingers
(Drawing, touching, picking up a coin.)
3 months---touch object
4 months---grab object
6 months---reach, touch, grab & hold
Mature grasp=pincer grasp
@ 9-14 months
gross motor - CORRECT ANSWER✅✅large body movements
