|
Cephalocaudal trend |
"head to tail" head develops more rapidly than limbs during prenatal period |
|
|
Proximodistal trend |
growth precedes from "near to far" head chest and trunk grow first |
|
|
Epiphyses |
Bone centers. cartilage cells at the extreme ends of each long body bone. upper epiphysis, growth plate, bone shaft, growth plate, lower epiphysis |
|
|
fontanels |
"soft spots" in the brain that allow for brain growth and bone overlapping in birth.
anterior is the largest, on the top of the head. |
|
|
neurotransmitters |
cross synapses. Elaborate communication system. Stimulation is vital for neuron survival
few neurons are produced after the prenatal period. |
|
|
synaptic pruning |
neurons not needed at a time return to an uncommitted state so they can support future development
|
|
|
Glial cells and Myelination |
Some glial cells participate directly in neural communication. about half of the brain. |
|
|
EEG |
One of the best ways to read brain-wave activity. electrodes go on as a cap |
|
|
Cerebral Cortex |
about half of the brain. Holds greatest number of neurons and synapses |
|
|
frontal lobe |
has the prefrontal cortex: responsible for thought. (consciousness, information, memory, problem solving, reasoning, planning. Functions effectively from 2 months on. forehead.
|
|
|
occipital lobe |
back of brain. in the cerebral cortex. contains visual cortex- sight lobe.
|
|
|
Parietal Lobe
|
language processing back middle |
|
|
temporal lobe |
long term memories, emotions,
bottom middle |
|
|
Lateralization |
right hemisphere: spatial, negative emotion
Left hemisphere: communication. |
|
|
Brain plasticity |
a plastic cerebral cortex has places that are not yet committed to specific functions. High capacity for learning.
