Document Summary
Chapter 2 (2p49): the systems of the body. Gets leukemia, goes into sepsis, six weeks later his kidneys regain function, he gets off dialysis and is in remission. Nervous system: complex network of interconnected nerve fibres that function to regulate many important bodily functions (including the response to and recovery from stress). Central nervous system: brain and spinal cord; carries voluntary nerve impulses to skeletal muscles and skin, carries involuntary impulses to muscles and glands. Peripheral nervous system: autonomic and somatic nervous system. Sympathetic nervous system: prepares body for emergencies, strong emotions, catabolic system, increased heart rate and tensing of muscles. Parasympathetic nervous system: works antagonistically, anabolic, restores the body to a normal state. Hindbrain and the midbrain: consists of the medulla, pons, and cerebellum. The medulla: regulation of heart rate, blood pressure, and respiration. Pons: serves as a link between hindbrain and midbrain, helps control respiration. Cerebellum: coordinates voluntary muscle movement, balance, maintenance of muscle tone and posture.
