Part One: Objectives and Topics

learning target

1. Make models of elbow extension and elbow flexion, and understand the principles of elbow extension and elbow flexion movements.

2. Name the components of the human movement system and describe the occurrence of body movements.

Explore topics

formation of body movement

1. The formation of body movement is completed by bones, joints, and skeletal muscles.

2. Principle: The excitement transmitted from the nerves stimulates the contraction of skeletal muscles and draws the bones around the joints, thereby producing body movement.

The formation of animal movement PPT, part 2: demonstration activities

Ask a classmate to perform a demonstration: holding a 3 kilogram shot put in hand, bending and extending the elbow.

The students paid attention to observe and record the contraction and contraction changes of his biceps and triceps muscles when he completed each step.

Make elbow extension and elbow flexion models

1. Purpose requirements

2. Materials and tools

3. Method steps

discuss

1. Can the model created by the students demonstrate the formation of elbow extension and elbow flexion movements well? If you can't make suggestions for improvements.

2. What roles do the biceps and triceps play in the formation of elbow extension and elbow flexion?

The formation of animal movement PPT, part 3 content: Class summary

1. The formation of body movement is completed by bones, joints, and skeletal muscles.

When skeletal muscles contract, the traction bones move around the joint, producing body movement.

2. Movement is formed with bones as levers, joints as fulcrums, and skeletal muscle contraction as power.

The contraction of skeletal muscles is coordinated and controlled by the nervous system. The energy consumed by exercise comes from the oxidative decomposition of organic matter in muscle cells.

A． Elbow dislocation b. humerus fracture

C. Skin damage D. biceps strain

2. Holding a bucket of water upstairs, the states of the biceps and triceps are ( )

A. Contraction, contraction B. Contraction, relaxation

C. diastole, contraction D. diastole, relaxation
