    (共41张PPT) 第六章 人体生命活动的调节 第三节 神经调节的基本方式 第四单元 生物圈中的人 教学目标 1. 概述人体神经调节的基本方式。 2. 描述反射的概念。 3. 区别简单反射和复杂反射。 4. 概述反射的结构基础——反射弧。 看字读颜色 红 黑 绿 蓝 黄 橙 黑 红 紫 棕 蓝 黄 粉 绿 紫 橙 注意,是读出字的颜色,不是字哦! 例如:黄 这个奇妙 的反应是 在人体哪 个系统的 调节下完 成的? 神经系统调节的基本方式是什么呢? ?? 反射 1、反射会在什么生物上产生? 2、反射是通过什么系统完成的? 3、反射是由什么原因引起的? 4、反射是一种什么类型的反应? 神经系统 外界或内部的 各种刺激 有规律的反应 人或动物 知识点一、反射 小组讨论 反射:是指人(或动物)通过神经 系统,对外界或内部的各种 刺激所发生的有规律的反应。 反射是神经调节的基本方式。 A B C D 思考与讨论:分析以下实例哪些是反射,哪些不是反射,并说明理由。 × × √ √ A.触碰含羞草的叶子会收缩 B.草履虫会趋向有利刺激,躲避有害刺激 C.小朋友看到食物流口水 D.球迷看到进球会欢呼鼓掌 注意:反射与应激性的区别 应激性:是生物体对外界刺激作出的反应 反射:是指人(或动物)通过神经系统,对外界或内部的各种刺激所发生的有规律的反应。 区别:是否有神经系统的参与 A.有物体在眼球前突然出现,会情不自禁的眨眼。 B.手偶然碰到火,来不及思考就立即缩回。 C.狗听到主人叫唤时,向主人奔去。 D.小孩的手被爆竹崩过后,不敢再放爆竹。 E.守门员看到足球向球门射来时,奋不顾身向球扑去。 F.婴儿膀胱里尿液多了,会马上排尿。 右边反射中哪些是 生来就会的,哪些 是后天形成的呢? 知识点二、反射的类型 缩手反射、膝跳反射、排尿反射等都 是比较简单的,是人生来就会的反射,这些反射受脊髓控制称为 简单的反射 复杂的反射:通过后天学习或生活经验获得的,这些反射受大脑控制。 反射 简单反射 (非条件反射): 复杂反射(条件反射): 在后天生活过程中通过训练学习 逐渐形成的后天性反射。 如:狗听到铃声流口水、人听到叫声回头、望梅止渴等。 先天就有的反射。 如:吮吸反射、膝跳反射、眨眼反射等 反射的类型: 说出下列叙述中反射的类型: 1、婴儿吮吸乳汁 2、一朝遭蛇咬,十年怕草绳 3、学生听见铃声,跑进教室 4、司机看见红灯,停止前进 5、风沙吹进眼里,出现流泪现象 简单反射 简单反射 复杂反射 复杂反射 复杂反射 酸梅 人在吃梅、看梅、说梅时都有分泌唾液的 现象发生,这些现象都是反射活动。 请你分析说说 它们各是哪种 类型的反射? 分析: 吃梅止渴 看梅止渴 谈梅止渴 简单的反射 复杂的反射 刺激物 口腔内的梅 吃过看到 吃过听说 获得途径 生来就有的 生活经验 生活经验及人类特有的中枢 反射类型 复杂的反射 这几种反 射其他动 物会吗? 看信! 看书! 人类特有的条件反射: 和语言文字有关 √ 1.小狗听到主人呼唤它的名字有反应 2.小狗听到主人“坐下”的指令便坐下 属于复杂反射 属于复杂反射 3.小狗看到到主人拿火腿肠,分泌唾液 4.小狗吃火腿肠的时候分泌唾液 属于复杂反射 属于简单反射 6.小狗听到主人说看书却没有反应 5.小狗听到主人“握手”的指令便握手 属于复杂反射 说明语言文字是人类特有的复杂反射 反射类型 形成 参与的神经中枢 停留 时间 简单反射 复杂反射 比较简单反射、复杂反射: 暂时 永久 脊髓 大脑 皮层 后天 获得 先天性 膝跳反射 两人一组做分组实验 做实验时请大家注意: (1)叩击部位:膝盖下方韧带。 (2)叩击时机:受试者放松且未注意。 (3)叩击力量:不一定要很大,但速度要快。 合作探究 反射的结构基础——反射弧 1、叩击韧带时,小腿有什么反应? 2、膝跳反射的神经中枢在哪里? 叩击韧带时,小腿突然地向上抬起。这种反射很小的孩子就有,是生来就有的。 膝跳反射神经中枢在脊髓内 3、如果大脑有意识的将腿部的肌肉收缩,膝跳反射能不能进行?说明什么? 不能进行,说明控制膝跳反射的脊髓(低级神经中枢)受大脑皮层的高级神经中枢支配。 合作探究 为什么有的反射可以不受大脑控制呢?要知道原因,我们需要研究反射的结构基础 ——反射弧 反射弧包括哪几个部分?想一想各有什么作用? 讨论 反射弧的结构 反射的结构基础 ---反射弧 感受器 神经 中枢 传出神经 传入神经 效应器 膝跳反射 韧带 传入神经 脊髓 传出神经 腿部相应肌肉 感受器 传入神经 神经中枢 效应器 (支配缩手的肌肉) 传出神经 缩手反射的形成过程 神经中枢 感受器 传入神经 效应器 传出神经 神经节 感觉 效应器做出反应 简单反射一般先有反射后有感觉,因为脊髓产生的神经冲动传到大脑的路径较长 1.若反射弧的④传入神经受损,刺激⑤会怎样? 2.若反射弧的②传出神经受损,刺激⑤会怎样? 3.若反射弧的⑥传向大脑的神经受损,刺激⑤会怎样? ⑥ 无反应无感觉 无反应有感觉 有反应无感觉 反射弧只有保持完整性才能完成反射活动。 还需要的条件:感受器接受到刺激,且刺激达到一定强度 痛觉产生:感受器→传入神经 →神经中枢→大脑皮层 (痛觉) 缩手反射: 感受器→传入神经→ 神经中枢→传出神经→效应器 (位于脊髓) 被火烫,是先缩手后痛, 还是先痛后缩手? 手会立即缩回,然后才感觉到痛。 保护机体不受伤害 神经调节 基本方式 反 射 结构基础 反射弧 包括 ① ② ③ ④ ⑤ 感受器 传入神经 传出神经 神经中枢 效应器 类型 简单反射 复杂反射 知识网络 1.下列生理活动属于反射的是 ( ) A、向日葵的花盘总朝向太阳转动 B、手偶然遇到火会突然回缩 C、皮肤出血后血液逐渐凝固 D、皮肤经日光长时间照射会变黑 B 我能行 ??? 2.下列现象中,属于人类所特有的反射是( ) A、吃梅子时,唾液腺分泌唾液 B、看到梅子时,唾液腺分泌唾液 C、听“梅子”时,唾液腺分泌唾液 D、人的手遇到火时会突然回缩 C 我能行 3.眨眼反射的神经结构和反射类型分别是 (  ) A.脑,简单反射               B.脊髓,复杂反射 C.反射弧,简单反射             D.反射弧,复杂反射 C 我能行 4.图中1、2、3、4、5组成在一起的结构称为( ) A.神经元 B.反射弧 C.神经 D.神经系统 B 我能行 5.反射和反射弧的关系是( ) A.反射活动可以不完全通过反射弧来实现 B.反射活动的完成必须通过反射弧来实现 C.只要反射弧完整,必然出现反射活动 D.反射和反射弧在性质上是完全相同的 B 我能行 6.人的手突然被针刺了一下,人体会( ) A、先感到疼痛,再缩手 B、先缩手,后感到疼痛 C、疼痛和缩手同时发生 D、只缩手,不会感到疼痛 B 我能行 7.下列各项中属于简单反射的是 ( ) A、小孩见到穿白大褂的大夫哭 B、精彩的表演引起观众大笑 C、鹦鹉见到客人会说“你好” D、吃到面包就会分泌唾液 D 课后作业 完成探究活动测定反射速度(对照P94) P95讨论 再 见
