Abstract
The utility model relates to a reflex arc demonstration teaching aid for biological classroom teaching, which comprises a demonstration plate, an analogue receptor, an afferent nerve, a nerve center, an efferent nerve, and a demonstration circuit and a demonstration pattern of an effector, wherein the demonstration circuit comprises a battery set (1), a box body electrode (2) arranged on the external wall, and a floodlight belt (5) connected through a plurality of line electrodes (3); and a bulb (6) is arranged in the middle of the floodlight belt, and the other end of the floodlight belt is connected with an electric flexible vesica (4). The reflex arc demonstration teaching aid for biological classroom teaching can vivaciously demonstrate the working process and principle of reflex arc, and the overall demonstration and particulars demonstration effects are good, thereby helping students to understand the classroom teaching knowledge.
Description
Technical field
The utility model relates to a kind of technical field of bioconversion medium teaching aid, is specifically related to a kind of biological classroom instruction reflex arc demonstration teaching aid.
Background technology
At present, teaching aid used in the high school biology teaching is a lot, but function singlenesses all just designs at the content that needs separately to show.In study nervous system reflex and basic mode is one of the important of biological class and the difficult point of beyonding one's depth, and student and teacher press for teaching aid targetedly, yet but are difficult to find this class teaching aid on market.Therefore the teacher is when the above-mentioned notion of explanation, can only be according to the textbook explanation, yet the knowledge that books are put down in writing is always more abstract hard to understand, especially lack the chance that the student starts to test, the enthusiasm that can not mobilizing students initiatively participates in, thereby bring certain difficulty to teaching, even have influence on student performance and learning interest.
The Chinese patent publication number is CN2904173, the utility model instructions that open day is on May 23rd, 2007 discloses " a kind of bioconversion medium apparatus ", this utility model Graphic Panel face is provided with the representative receptor, afferent nerve, nerve center, the pattern of efferent nerve and effector, be connected with afferent nerve between wherein said receptor and the nerve center, be connected with efferent nerve between nerve center and the effector, described representative receptor, afferent nerve, nerve center, be provided with the digital display pipe on the plate face back side of the pattern position of efferent nerve and effector, so that make the pattern on the plate face front shinny during energising, strengthen the demonstration effect, described digital display pipe is connected on the control circuit by lead.Have that intuitive is strong, processing ease, show the characteristics of nervous system reflex comprehensively, both be convenient to the teacher and finished teaching task quickly, improved the interest and the manipulative ability of student's study again, very helpful to cultivating students ' analysis problem and problem-solving ability.But it is bad that this utility model is demonstrated effect on the whole, unthoughtful in the details demonstration, and the effect during classroom instruction is used is still waiting to improve.
The utility model content
The purpose of this utility model is to demonstrate deficiencies such as weak effect at bioconversion medium apparatus demonstration weak effect, the details of existing reflex arc, provides a kind of integral body and details demonstration effect all biological preferably classroom instruction reflex arc demonstration teaching aid.
The purpose of this utility model realizes by following technological means: a kind of biological classroom instruction reflex arc demonstration teaching aid, include the illustrative circuitry and the demonstration pattern of demonstration board and simulation receptor, afferent nerve, nerve center, efferent nerve, effector, described illustrative circuitry includes the canister electrode that is provided with on electric battery and its outer wall, and be connected with the light diffuser band by several lines electrodes, centre at the light diffuser band also is provided with bulb, and the other end of described light diffuser band also is connected with the electric expansion vesica.
Compared with prior art the utlity model has following tangible advantage: this biological classroom instruction can vivid demonstration go out the process and the principle of reflex arc work with the reflex arc demonstration teaching aid, whole demonstration and details good demonstration effect, easier help student understands classroom instruction knowledge.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-electric battery, 2-canister electrode, 3-lines electrode, 4-electric expansion vesica, 5-light diffuser band, 6-bulb.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
A kind of biological classroom instruction reflex arc demonstration teaching aid as shown in Figure 1, include the illustrative circuitry and the demonstration pattern of demonstration board and simulation receptor, afferent nerve, nerve center, efferent nerve, effector, described illustrative circuitry includes the canister electrode 2 that is provided with on electric battery 1 and its outer wall, and be connected with light diffuser band 5 by several lines electrodes 3, centre at light diffuser band 5 also is provided with bulb 6, and the other end of described light diffuser band 5 also is connected with electric expansion vesica 4.Be provided with like this, many the nerve fibres of dispersing of receptor are simulated in this biological classroom instruction by several lines electrodes 3 with the reflex arc demonstration teaching aid, simulate afferent nerve and efferent nerve by light diffuser band 5, come the analog neuron maincenter, come the mimic effect device with electric expansion vesica 4 with bulb 6; When concrete class demonstration, the teacher can contact any in several lines electrodes 3 with canister electrode 2, and then startup entire circuit, light light diffuser band 5, bulb 6 successively, and startup electric expansion vesica 4 carries out stretching motion, so just can vivid demonstration go out the process and the principle of the work of entire emission arc, whole demonstration and details good demonstration effect, easier help student understands classroom instruction knowledge.
In a word, the utility model provides a kind of integral body and all biological preferably classroom instruction reflex arc demonstration teaching aid of details demonstration effect.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
Claims (1)
1. biological classroom instruction reflex arc demonstration teaching aid, include the illustrative circuitry and the demonstration pattern of demonstration board and simulation receptor, afferent nerve, nerve center, efferent nerve, effector, it is characterized in that: described illustrative circuitry includes the canister electrode (2) that is provided with on electric battery (1) and its outer wall, and be connected with light diffuser band (5) by several lines electrodes (3), also be provided with bulb (6) in the centre of light diffuser band (5), the other end of described light diffuser band (5) also is connected with electric expansion vesica (4).
