Document Summary
Elementary school years children grow 2-3 inches per year. Middle late childhood 5-7lbs weight gain per year (muscles and skeletal changes) Baby fat transitions to muscle- double in strength. Proportional physical changes greatest in middle/ late childhood. Brain increased myelination:the physiological process of covering neurons in a fatty sheath called myelin. It is important for nerve conduction, it is linked with cognitive development, and is largely determined by genetics, but can be affected by experience. Parts of the cns that are integral to survival are myelinated first, such as the spinal cord. (faster effective processing information) Significant changes in structures and regions (attention, reasoning, cognitive control) Increased executive functioning- inhibition of behavior and flexible thinking/behavior. Synaptic pruning occurs (synaptic pruning refers to the process by which extra neurons and synaptic connections are eliminated in order to increase the efficiency of neuronal transmissions) Hands used more as tools and steadier by age 7. Average child"s body weight doubles during middle/late childhood.
