Link to class recording from Jan 2023

Here is a link to our Jan 12, 2024 class session recording.

After studying this unit, you will be able to:

  1. Explain the structure and function of muscles and muscle tissue
  2. Describe the sliding filament theory
  3. Interpret the names of various muscles based on Latin terms
  4. Examine the types of movement muscles can achieve

The video above will help you review the way muscles work from a microscopic perspective. You can use the information from the video to help answer the questions in this section. We will also review these questions during our lesson on 10/6/23
Question 1

  • Voluntary
  • Involuntary

What is a motor neuron.

Question 4

Question 11
11.

Wow, that was a lot of new information!

What do you think about the muscular system so far?
Do you prefer learning about the micro side of things, like how the molecules work together in a sarcomere?
Do you prefer the macro side of things, like the parts we can see without a microscope, such as designing exercises to target specific muscles?

Select all of the functions of the muscular system. (there are 4 correct choices)
