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 Who is Esther Thelen?- focused on infant motor development
