What are the 3 sequences of physical development?
cephalocaudal development
Promimodistal development
Differentiation
What is cephalocaudal development?
Development proceeds from the upper part of the head to the lower parts of the body
What is Proximodistal development?
Growth and development also proceed from the trunk outward, from the body’s central axis toward the periphery
Define differentiation

What are some guidelines for infant nutrition?
- Build-up to a variety of foods
- Pay attention to infants’ appetite
- Don’t restrict fat & cholesterol too much; babies need calories and some fat
- Don’t overdo high-fiber foods
- Generally, avoid items with added sugar and salt
- Encourage eating of high-iron foods
What is a dendrite?
Root-like parts of neurons that receive impulses from other neurons
What is a axon?
A long, thin part of a neuron that transmits impulses to other neurons through branching structures called axon terminals
What is the medullas function?
Heartbeat and respiration
What is the cerebellum function?
Help maintain balance, control behavior, and coordinate eye movements with bodily sensations
What is the function of the cerebrum?
Thought, memory, and language
What is an ulnar grasp?
Holding objects between fingers and palms
What is pincer grasp?
Oppositional thumb comes into play, enabling infants to pick up objects with finger and thumb
What is locomotion?
Movement from one place to another
What is a creeping motion?
Infant move themselves along on their hands and knees
When does the creeping motion appear?

What does the development of vision involve?
Visual acuity(sharpness), development of peripheral vision, depth perception, perceptual constancies(knowing an object is the same object no matter how you look at it from different angles)
What is perceptual constancy?
perceiving objects as maintaining their identity although sensations from them change as their positions change
What is habituation?
Becoming used to a stimulus and therefore paying less attention to it
