Document Summary
4: nervous system 1: structure and organization: neuroanatomy. Autonomic nervous system: help you rest or panic. Large mass, small mass specific metabolic rate. Applies to active metabolism: big means less. Same size proportion for every size class of vertebrate. Alcohol: liver scales and blood scales differently, more mass: handle more. Per kg: underdose kids and overdose adults. Kids mass specific metabolic rate is faster so it clears the drug. Adults mass specific metabolic rate is slower. Clearance scale factor: how effectively drug is processed through body. Not for all parts: skin is different from blood stream for scaling relationship. Network of billions of nerve cells linked together to form the rapid control center of body. In brain: 100 billion neurons and 100 trillion synapses: connections btw. Integrating center for info coming into body from periphery or internally, sensation. Nervous system outside brain and spinal cord. Some info, afferent and efferent, that doesn"t make it to cns.
