what happneswith lymph nodes after puberty
thymus, tonsils, lymph nodes regress after puberty
what happens to the reproductive system and CNS at puberty
continued growth by sex harmones for reproductive system, continued growth in CNS as synapses and glial cell numbers, and myelination.
talk about the growth patern for the heart and the brain.
the heart is isometric with alometric (growth with percpective to body) value of 0.98 and the brain is hypoallometric, with alometric coeficent value of 0.73, before growth stops once body grows till age 6, then is slows down becoming smaller than the bpdy.
what is cephalocaudal and proximodestal principle
cephalocaudal principle = growth from top down
proximodistal principle, centre to outwards.
what is the difference between grey matter and white matter
grey matter: Neuronal cell bodies and dendrites (information processing)
white matter: bunndles of myilinated axons that connect gray matter regions together, communication.
how does the synapse density change throught life
more dence, like more scratches.
what should be fully developed by age 4
primary senses and basic motor skills are almost fully developed
what is the critical period
Finite period where the child has hightened senistivity to external stimulus that is requires for development of a skill - visual cortex
What is sensative period
stages during development when development of a skill is easier due to greater sensitivity to environmental stimuli language acquisition.
talk about the learning for language area in the brain
wernicke’s area: language learning, continues to develop through age 10, but goes through pruning as well.
How does Reason look at the age of 6
it not good bru, still fevelopmping, in the prefrontal cortex. that why they go cray cray with too much options.
By when is fine motor skills good,
its great at 8 or 9.
at what age is math skills good and why
at age 9 bc the parietal lobes are formed good. and can be enhanced with flash cards
when is judgement good?
age 13, bc the prefrontal cortex is fully developed at this point
when most emotional
13, bc in the limbic system a capacity for creating emtion big
when is logic the best
age 13 bc pariteal lobes finna forming at a rapid rate, so beter anayltical abilities are developing.
when does specialization occur
at 15, where abundance of neural links continue to be discarded. Underused connections will die to help more active connections thrive.
When abstract thought finna good
when the maturing pre-frontal cortex is the best matured. at 17 years, wehre they can handle complex probs
what happens to brain at 21 years old
executive functions, still development in the emotions and all that, maturation as well most brain mature and dat.
