Document Summary
Anterior pituitary content not related to gh level: gh is produced as it needed -> anterior pituitary does not store gh. Children have more pulses /24 hours: higher level than adults. Gh concentration increase during childhood: reaches peak level at phv (13, largest growth time in the adolescent period (highest magnitude of. Gh concentration (magnitude) declines into adulthood pulses (nocturnal = at night: just before adolescent -> decrease, at adolescent -> major increase, adulthood -> decrease to preadolescent level. Graph-mean 24 hour plasma concentration of growth hormone in boys. At phv -> total gh concentration is the greatest. Adult level -> level similar to preadolescent (8-11yrs) Total concentration = #pulses of gh release (in a day) + #gh release per pulse. 2nd graph -> amount of gh released per pulse. The size of pulses (pulse magnitude) is greatest in late adolescent -> phv time. 3rd graph -> number of pulses in 24hr.
