Human medical nerve reflex arc model and central nerve conduction psycho-neural modelthis reflex arc model visualizes the conditional reflex mechanism with a 3x magnification, accurately displaying five core structures: receptor, afferent nerve, nerve center, efferent nerve, and effector. made of pvc, it uses color-coding (e.g., yellow for afferent nerves, orange for efferent nerves) to clarify nerve signal transmission, serving as a key teaching aid for medical and biological education.specificationsproduct name: reflex arc nerve conduction modelproduct size: 53*38*10cmmaterial: pvcscope of application: teaching, demonstration, doctor-patient communicationnote:1.please allow 0-1cm error due to manual measurement. 2.please allow a little color difference due to the different screen or light environment.3.if you have any questions or concerns, please feel free to email us and we will do our best to meet your requirements within 24 hours.
