A

A deficiency of one or more key nutrients, such as proteins, vitamins, or minerals, that has a significant impact on energy and the function of bodily systems

30

myelination
.

A brain or nerve cell that serves as the basic building block of the nervous system.

38
Q

on-demand breastfeeding

A

Nursing a baby whenever the baby shows signs of hunger during the day and night, such as by crying or rooting, rather than according to a set schedule.

38
Q

otitis media

A

Infection of the middle ear and a common cause of earaches.

Q

newborn reflex

A

An inborn automatic response to stimuli, which may disappear before the end of the first year

39
Q

non-rapid-eye-movement (NREM) sleep

A

A sleep state during which rapid-eye-movement and dreaming do not occur, and brain-wave activity is slow and regular.

40
Q

plasticity

A

Changes in the brain resulting from our interactions with the environment; influenced by agerelated change.

41
Q

preterm

A

An infant born before 32 weeks gestation.

42
Q

protein-energy malnutrition (PEM)

A

A type of malnutrition in which insufficient food intake results in a significant lack of protein and calories.

43
Q

rapid-eye-movement (REM) sleep

A

A sleep state during which rapid and random eye movements, intense and irregular brain-wave activity, and dreaming occur.

44
Q

schemes

A

Mental structures that help us organize and process information.

45
Q

sensation

A

Physical reception of stimulation.

46
Q

sensorimotor stage

Q

sudden infant death syndrome (SIDS)

A

The term used to describe the sudden and unexplained death, usually during sleep, of a seemingly healthy infant younger than 1 year of age.

48
Q

synapse

A

The space between adjoining neurons, across which electrical impulses are sent from the axon of one neuron to the dendrite of another.

49
Q

synaptic pruning

A

The process by which the brain removes unused synapses through redirecting nutrition, cell injury, and cell death.

50
Q

telegraphic speech

A

The creation of short phrases that convey meaning but lack some of the parts of speech that are necessary for a full and complete sentence.
