XY-3325 Human Functional Elpow Joint 1. Model use:Demonstrate collaboration in skeletal muscle movement. The relationship between flexion and extension of the biceps and triceps. Ii. Teaching Content: The demonstration will deepen the student's concept of the biceps and triceps starting and ending points. The muscles must cross the elbow joint and the elbow joint must operate with an understanding that the cubohumeral position is relatively fixed, and the lever action that can be mechanically understood by rotating around the axis can cause rotation. 3. Components: 1. Bones and right hand. 2, a bracket (with nut screws). 3, two muscles (biceps, triceps). 4, the chassis is only a piece of iron. 4. Presentation method The skeleton is mounted on the chassis support, and then the upper and lower two muscles are hooked to the fixed position of the two ends of the skeleton model. During the demonstration, one hand holds down the chassis, and the other hand can pull the model hand up and down, that is, to observe the relationship between the biceps and triceps relaxation and contraction, extension and flexion movement, and to understand the lever action caused by the rotation of the axis from the mechanics. |
