Question
Hi can you please help me in those activities. Already tried to draw them but it’s wrong .
**Activity 1** Use your computer to view images of skeletal, cardiac, and smooth muscle tissues. Draw a picture of each type of tissue in the spaces below. You should be able to identify the following structures in the appropriate images: *striations, nuclei, fibroblasts, intercalated discs*. - **Diagram Explanation:** - **Skeletal:** This circle is designated for drawing skeletal muscle tissue. Look for striations and multiple nuclei. - **Cardiac:** This circle is for drawing cardiac muscle tissue. Identify striations, a single central nucleus, and intercalated discs. - **Smooth:** This circle is for drawing smooth muscle tissue. Note the absence of striations and a single nucleus per cell.

### Activity 2 #### Instructions: - Examine a plastic model of a skeletal muscle fiber. Identify the following structures on the model: - **Axon of motor neuron** - **Synaptic knob** - **Motor end plate** - Notice the "ruffled" texture of the motor end plate. #### Microscope Observation: - Use your computer to view microscopic images of the neuromuscular junction. In the images: - Look for dark lines (axons) spreading across the fibers. - Once you have found the axons, trace them as they lead to synaptic knobs. #### Identify the Following: - **Muscle fibers** - **Axons** - **Synaptic knobs** A neuromuscular junction exists wherever a synaptic knob joins a muscle fiber. Draw a picture illustrating this connection. --- Note: This activity helps in understanding the intricate structure and function of the neuromuscular system by analyzing both models and microscopic images.
