Development (1.6) Flashcards
What’re Critical Periods?
period in development where children are particularly susceptible to environmental factors
How does Neurulation occur?
when the ectoderm
overlying the notochord begins to furrow, forming a neural groove surrounded by two neural folds
What does the neural tube form?
CNS
What does Alar plate of neural tube form?
sensory neurons
What does Basal plate of neural tube form?
motor neurons
How is the fetus attached to the uterine wall?
Via the umbilical cord

Maternal malnutrition, Protein deficiency can slow growth, lead to intellectual

Moro Reflex
- Infants react to
abrupt movements of their heads by flinging out their arms, then slowly retracting their arms and crying. - usually disappears after four months and its continuation at one year is a strong suggestion of developmental difficulties
Babinski Reflex

Grasping Reflex
occurs when infants close their fingers around an object placed in the hand.
