Question 1

Question 2

Answer 2

Question 3

Endocrine Gland(s)

Answer 3

Organs in the endocrine or hormonal system that secret chemicals called “hormones” directly into the bloodstream.

Question 4

Pituitary Gland

Answer 4

Perhaps the most critical of the endocrine glands; the so-called “master gland” located at the base of the brain; controlled by the hypothalamus; triggers the release of hormones from all other endocrine glands by sending hormonal messages to those glands.

Question 5

Growth Hormone

Answer 5

The hormone responsible for triggering specialized hormones the directly regulate growth.

Question 6

Androgens

Answer 6

Male hormones that help trigger the adolescent growth spurt and the development of the male sex organs, secondary sex characteristics, and sexual motivation.

Question 7

Estrogen

Answer 7

The female hormone responsible for the development of the breasts, the female sex organs, and secondary sex characteristics and for the beginning of menstrual cycles.

Question 8

Neuron

Answer 8

The basic unit of the nervous system; a nerve cell.

Question 9

Synapse

Answer 9

The point at which the axon or dendrite of one neuron makes a connection with another neuron.

Question 10

Myelination

Answer 10

The depositing of a fatty sheath around neural axons that insulates them and thereby speeds the transmission of neural impulses.

Question 11

Plasticity

Answer 11

An openness of the brain cells (or of the organism as a whole) to positive and negative environmental influence; a capacity to change in response to experience.

Question 12

Lateralization

Answer 12

The specialization of the two hemispheres of the cerebral cortex of the brain.

Question 13

Neurogenesis

Answer 13

The process of generating new neurons across the lifespan.

Question 14

Cephalocaudal Principle

Answer 14

The principle that growth proceeds fromt the head (cephalic region) to the tail (caudal region).

Question 15

Proximodistal Principle

Answer 15

In development, the principle that growth proceeds from the center of the body (or the proximal region) to the extremities (the distal regions).

Question 16

Orthogenetic Principle

Answer 16

Werner’s principle that development proceeds from global and undifferentiated states toward more differentiated and integrated patterns of response.

Question 17

Reflex

Answer 17

An unlearned and automatic response to a stimulus.

Question 18

REM Sleep

Answer 18

A state of active, irregular sleep associated with dreaming; named for the rapid eye movements associated with it.

Question 19

Developmental Norm

Answer 19

The age at which half of a large group of infants or children master a skill or display a behavior; the average age for achieving a milestone in development.

Question 20

Gross Motor Skills

Answer 20

Skills that involve large muscles and whole body or limb movements (for example, kicking the legs or drawing large circles). Contrast with fine motor skills.

Question 21

Fine Motor Skills

Answer 21

Skills that involve precise movements of the hands and fingers or feet and toes. Contrast with gross motor skills.

Question 22

Locomotion

Answer 22

The process of moving from one location to another.

Question 23

Ulnar Grasp

Answer 23

Holding objects by clamping them between the palm of the hand and the fingers.

Question 24

Pincer Grasp

Answer 24

A grasp in which the thumb is used in opposition to the fingers, enabling an infant to become more dexterous at listing and manipulating objects.

Question 25

Rhythmic Stereotypies

Answer 25

Repetitive movements observed in infants shortly before a new motor skill emerges.

Question 26

Dynamic Systems Theory

Answer 26

A perspective on development applied to motor development which proposes that more sophisticated patterns of motor behavior emerge over time through a "self-organizing" process in which children modify their motor behavior in adaptive ways on the basis of the sensory feedback they receive when they try different movements.

Question 27

Congenital Malformations

Answer 27

Defects that are present at birth and are caused by genetic factors, prenatal events, or both.

Question 28

Reaction Time

Answer 28

The interval between the presentation of a stimulus and a response to it.
