muscle system
2.Method Using septic model of rats,we established the in vitro muscle incubation system with suf- ficient oxygen supply as well as the NADH fluoremetric method for the detection of trace amount of lactate in the samples. Extensor digitorium longus(EDL)and soleus muscles which represent two types of muscle fiber were studiedd.
5.The experiment on different sports items showed that the exponent of waist-stern of seniors distinctly dropped, the exponent of vital capacity increased currently, the heart rate in quiet moment is lower, shrink pressure and stretch pressure of the accepter in the blood pressure on the high side are get back to normal range, which indicates that the scientific exercise can build up skeleton muscle, improve the function of respiration system and circulation system.
7.General principles for activities of nervous; Synapse and synaptic transmission; The basic process of classical synaptic transmission; Postsynaptic potential: excitatory postsynaptic potential and inhibitory postsynaptic potential; The conception of transmitter and receptor: mostly transmitter and receptor system; Reflex and reflex arc; The characters of central excitatory transmission, central inhibition; The motor unit of skeleton muscle; Stretch reflex; The function of autonomic nervous system and their chemistry transmission.
