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

Introduction
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
4

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

9

There are three characteristics to match with each of the types of muscle.

Some of the characteristics are used more than once but each category will only have 3 correct answers.

  • Voluntary
  • Involuntary
  • Striations
  • No striations
  • Makes up the structure of the heart
  • Found in digestive system, blood vessels, etc.
  • Found attached to bones
  • Cardiac muscle
  • Skeletal muscle
  • Smooth muscle

Drag the terms to complete the diagram showing labels of the region names.
Other Answer Choices:
Oculi

1

The deltoid muscle is shaped like a trapazoid.

5

Match the name of each muscle below with its location.
Use the information we learned about muscle naming based on shape and region terms.

You can go back to the recording (linked at top of this assignment) or class slides (found in class announcements) to help you with this question.

Draggable itemCorresponding Item
Biceps brachii
Thigh, runs parallel along the midline
Intercostals
In the arm, has two points of origin
Latissimus dorsi
Wide muscle located in the back
Tibialis anterior
Front of the leg
Rectus femoris
In between the ribs
Skeletal muscle action
1

A muscle origin is attached to the fixed bone; the insertion of the muscle is attached to the bone that will move.

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?
