01. jaw muscle

jaw [dʒɔː] n.下巴；颌

temporomandibular joint   颞下颌关节

temporomandibular  [tempərəʊmæn'dɪbjʊlə(r)] adj.颞下颌的 

The temporomandibular joint (TMJ) acts like a sliding hinge, connecting your jawbone ([ˈdʒɔːˌbəʊn] n.下颌骨) to your skull. You have one joint on each side of your jaw. 

temporalis muscle 颞肌 The temporalis muscle is a thin, fan-shaped muscle situated within the temporal fossa (['temp(ə)rəl] ['fɒsə]颞窝) of the skull. Along with the medial pterygoid ( ['mi:diəl]  ['terəgɔɪd] 翼内肌), lateral pterygoid ([ˈlæt(ə)rəl] ['terəgɔɪd]  翼外肌) and masseter muscles ([mæ'seɪtə] n.【解】咬肌), it belongs to the group masticatory muscles (['mæstɪkətərɪ] adj.咀嚼的).

lateral pterygoid ([ˈlæt(ə)rəl] ['terəgɔɪd] 翼外侧肌

masseter muscle [mæ'seɪtə] n.【解】咬肌

buccinator muscle [bʌksɪ'neɪtə] un.颊肌

02. regain [rɪ'ɡeɪn] n.恢复；复得；收复

03. myasthenia gravis na.【医】重症肌无力

04. neostigmine [ˌni:əʊ'stɪgmi:n] n.新斯的明 Neostigmine is a parasympathomimetic ([pærəsɪmpəθəʊmɪ'metɪk] adj.副交感神经性的) agent that acts as a reversible acetylcholinesterase ([æsɪtɪlkəʊlɪ'nestəreɪs] n.乙酰胆碱酯酶) inhibitor.

05. acetylcholinesterase (AChE) [æsɪtɪlkəʊlɪ'nestəreɪs] n.乙酰胆碱酯酶 an enzyme that occurs chiefly in cholinergic ([ˌkoʊlə'nədʒɪk] adj.类胆碱(功)能的) nerve endings and promotes the hydrolysis ([haɪˈdrɒləsɪs] n.水解（化合物的加水分解）of acetylcholine ([ˌæsɪtɪl'kɒli:n] n.乙酰胆碱)

06. synaptic transmission un.突触传递 Synaptic transmission is the key process in the integrative (['ɪntɪgreɪtɪv] adj.综合的) action of the nervous system. Synaptic transmission is the process at synapses (['saɪnæps] n.突触) by which a chemical signal (a transmitter) is released from one neuron and diffuses to other neurons or target cells where it generates a signal which excites, inhibits or modulates ([ˈmɒdjʊleɪt] v.调节) cellular activity.

07. endplate potential (EPP) 终板电位 The end-plate potential is a graded potential (it is not all-or-none) that propagates ([ˈprɒpəɡeɪt] v.传播) electrotonically to the neighboring patch of muscle fiber membrane where it initiates an action potential on the muscle much like it does on unmyelinated ([ʌn'maɪəlɪneɪtɪd] adj.无髓的) nerves.

08. ionic [aɪ'ɒnɪk] adj.离子的 of, relating to, existing as, or characterized by ions

09. degradation [.deɡrə'deɪʃ(ə)n] n.退化；降低

10. exocytosis [eksəʊsaɪ'təʊsɪs] n.胞吐作用 the release of cellular substances (such as secretory products) contained in cell vesicles (['vesɪkl]n.（动植物体内的）泡囊) by fusion of the vesicular([və'sɪkjʊlə] adj.多泡(状)的) membrane with the plasma membrane and subsequent (['sʌbsɪkwənt] adj.随后的) release of the contents to the exterior (ɪkˈstɪəriə(r)] n.外观；外表 adj.外面的) of the cell

11. vesicle ['vesɪkl]n.（动植物体内的）泡囊 a membranous (['membrənəs] adj.膜；膜状的) and usually fluid-filled pouch ([paʊtʃ]n.小袋子) (such as a cyst, vacuole (['vækjuəʊl]n.泡), or cell) in a plant or animal

12. fatigue [fəˈtiːɡ] n.疲劳；劳累 weariness (['wɪərɪnəs] n.疲倦) or exhaustion from labor, exertion ([ɪɡˈzɜː(r)ʃ(ə)n] n.费力，尽力), or stress

13. excitatory postsynaptic potential (EPSP)兴奋性突触后电位

14.nicotinic [ˌnɪkə'tɪnɪk] adj.【化】烟碱(酸)的 relating to, resembling, producing, or mediating the effects produced by nicotine ([ˈnɪkətiːn] n.烟碱；尼古丁) on nerve fibers at autonomic ganglia ([ˌɔːtə'nɒmɪk] ['ɡæŋɡliə] un.自主神经节) and at the neuromuscular junctions of voluntary ([ˈvɒlənt(ə)ri] adj.自主的) muscle which increases activity in small doses and inhibits it in larger doses

15. endplate ['endpleɪt] n.终板 a complex terminal treelike branching of the axon of a motor neuron that contacts with a muscle fiber

16. inhibitory synapse un.抑制性突触 A synapse which passes an inhibitory signal to its post-synaptic neuron or neurons causing it or them to be less likely to have an action potential or to have reduced frequency of action potentials

17. neurotransmitter ['njʊərəʊtrænzmɪtə(r)] n.神经递质（在神经细胞间或向肌肉传递信息） A neurotransmitter is the body’s chemical messenger. They are molecules that transmit signals from neurons to muscles, or between different neurons. The transmission of signals between two neurons occurs in the synaptic cleft ([kleft] n.裂缝).

18. inhibitory postsynaptic potential (IPSP) un.抑制性突触后电位 increased negativity of the membrane potential of a neuron on the postsynaptic side of a nerve synapse that is caused by a neurotransmitter (as gamma-aminobutyric acid un.γ氨基丁酸 ) which renders the membrane selectively permeable to potassium ([pə'tæsiəm] n.钾) and chloride ( [ˈklɔːraɪd] n.氯化物) ions on the inside but not to sodium ([ˈsəʊdiəm] n.钠) ions on the outside and that tends to inhibit the neuron since an added increase in potential in the positive direction is needed for excitation

19.ionotropic [aɪˌɒnəˈtrɒpɪk] 离子型 ionotropic receptors, also called ligand-gated channels, are ion channels that are opened by the binding of neurotransmitters; a receptor that functions directly by opening ion channels that enable specific ions to stream ([striːm] v.流；流动) in an out of the cell
