Know height weight changes across the lifespan what

Know height & weight changes across the lifespan. What is menarche,
semenarche? In what months of the year do men produce the most testosterone? Menopause &
andropause. Complete charts below.
Brain weight:
Age Brain weight
Birth _25_ % of adult weight
2 yrs _75__ % of adult weight
5 yrs _90__ % of adult weight
Growth:
Average weight/length at birth _20” long_/_7-7.5 lbs_
Growth rate in first year _once a day and a lb per month_
Average weight at age 2 __50% of adult weight 27-30__

Growth rate from 2yrs to puberty _2-3” and 5-6 lbs per
year_
Whose adolescent growth spurt is first? (boys or girls?) GIRLS
Nervous system . Neuron, basic parts/functions (voice—over powerpoint on
Blackboard).
1. Dendrite- bring info to the cell body
2. Soma- cell body that contains the nucleus
3. Nucleus- information in it to help the neuron do its job of sending the
message
4. Receptor-
5. Axon hillock- connects to the axon and is that last site in the soma
where the membrane potentials propagated from synaptic inputs are
summated before being transmitted to the axon
6. Axon terminal- transmit impulses from one neighboring neuron to the
next
CNS: Brain & spinal cord.
PNS: Motor, sensory & autonomic nerves (lecture).
Know a few basic functions of the 4 lobes
1. Frontal: strategy formation, associative learning, attention, risk taking,
motor inhibition, smell, spontaneity, Brocas- speech production
2. Parietal: tactical sensory- touch sensory, joint position, muscle tension,
math ,body image, spatial ability and drawing,
3. Temporal: speech comprehension (werkickie’s area), categorization
and organization, memory (hipporcampus), fear (amygdala)
4. Occipital: vision
5. the cerebellum (lecture): motor coordination, balance.
Know specializations of the left and right hemispheres, which visual field
sends information to each hemisphere and which side of the body each
hemisphere controls. At what age does the brain reach its full adult weight?
Motor Output is crossed in the brain stem
1. Right hemisphere controls LEFT SIDE of the body
2. Left hemisphere controls RIGHT SIDE of the body
Connections in SYNC
Left Brain- “happy hemisphere”
1. Laughter

2. Language- speech
3. Logic, thinking- reasons
4. Lists
5. Controls right hand
Right Brain
1. simultaneous processing
2. emotional
3. faces
4. mute- cannot initiate speech
5. pictures/spatial
6. controls left hand
Dynamic systems approach: proposes that the more sophisticated patterns
of motor behavior emerge over time through “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
orthogenetic principle: Werner’s principle that development proceeds from
global and undifferentiated states toward more differentiated and integrated
patterns of response
cephalocaudal principle: development from head to tail (2-3 months)
lifts head before controlling trunk to turn, sits up before
controlling legs to walk (3-4 months)
proximodistal principle: development begins in the trunk to extremities
moves arms and legs before center grasp
