Color the motor neuron yellow.

Images of farm animals coloring pages. As they read through the steps students color the model which includes actin and myosin filaments the motor neuron cross bridges and chemicals like calcium and acetylcholine. Students color and answer questions. Answer questions 1 6 skip over question 7 then answer questions 8 and 9.

The sliding filament theory explains muscle contraction based on how muscle fibers actin and myosin slide against each other to generate tension in the overall muscle. Sarcomeres repeat themselves over and over along the length of the myofibril. Filament would slide back on the thick filament.

This activity allows students to see how the thick and thin filaments slide past each other. The diagram above shows part a myofibril called a sarcomere. This worksheet lists the steps involved in the sliding filament model of muscle contraction and includes a coloring page of the model.

Sliding filament theory the sliding filament theory explains muscle contraction based on how muscle fibers actin and myosin slide against each other to generate tension in the overall muscle. Many myosins about 200 make up each thick filament so there are many myosin heads cross bridges available to bind the thin filament. A muscle contraction starts in the brain where signals are sent along the motor neuron a.

This worksheet provides a step by step guide of the sliding filament model where contraction starts with a nerve impulse and ends with the muscle fibers shortening. Describes how muscles contract according to the sliding filament theory. Introduces muscle contraction and the sliding filament theory.

The sliding filament theory is a model for muscle contraction that involves the actin and myosin filaments that make up the sarcomere sliding past each other. After answering question 9 click the back to topic button on the left side of the screen. The sliding filament theory in a muscle can be a challenging topic for students to visualize.

In this animation you see only four of these cross bridges but keep in mind there are many more on each thick filament. These filaments slide in and out between each other to form a muscle contraction hence called the sliding filament theory. Here is a fairly basic overview.

Color highlighted text notes. This page will be removed in future. This is the smallest unit of skeletal muscle that can contract.

This would be great to use as a partner activity or to send home with students to help with their on studying.
