Document Summary

Nervous and endocrine system make up homeostatic control. Three parts to control: receptor: somewhere in body that measures stimuli directly and sends it to the. , control centre that has a set point that determines the limits that that condition should regularly fall between. The stimuli comes in to control centre along afferent pathway: effector: info from control centre along efferent path to effector which controls response to control centre"s analysis of the stimulus. Homeostatic imbalance: aging control systems for internal environment become less efficient, we are more susceptible to disease, negative fb is overwhelmed and positive feedback takes over becomes destructive . Both have motor fibres, however there are differences. Effectors: somatic skeletal muscles for conscious control, autonomic heart muscles and smooth muscles in organs, glands. Because there is little to no myelination, the auto is much slower than somatic (think of sleep, we release melatonin but it takes a while to make us feel very sleepy)
