Simple Muscular System Diagrams for Kids - Learn Muscles and Movements

Facial Muscles and Their Functions
The face contains several important muscles that control various expressions and movements:
- Frontalis: Moves eyebrows up and wrinkles the forehead
- Temporalis: A chewing muscle of the upper jaw that covers the temporal bone
- Zygomaticus major: Responsible for smiling
- Sternocleidomastoid: Rotates the head and flexes the neck
- Masseter: Primary chewing muscle
- Orbicularis oculi: Controls eye movements
- Orbicularis oris: Encircles the mouth
Example: The masseter muscle is crucial for mastication and keeps the mouth shut when not in use.
These facial muscles work together to create various expressions and facilitate essential functions like eating and speaking. Understanding their locations and functions is vital for health science students studying the muscular system.
Highlight: The temporalis muscle, located on top of the head, is another important muscle involved in chewing.
Major Muscles of the Body
This section focuses on the major muscles of the body, their locations, and functions:
- Quadriceps: A group of four muscles on the front of the thigh Vastus lateralis Rectus femoris Vastus medialis Vastus intermedius
- Foot movements: Dorsiflexion: Toes up Plantarflexion: Toes down
- Upper body muscles: Sternocleidomastoid: Attaches to three points Trapezius: Large muscle of the upper back and neck Deltoid: Shoulder muscle with anterior, middle, and posterior portions Pectoralis major: Large chest muscle Triceps brachii: Three-headed muscle on the back of the upper arm Rectus abdominus: "Six-pack" muscle of the abdomen
- Lower body muscles: Sartorius: Long, thin muscle of the thigh Gluteus maximus: Large muscle of the buttocks Hamstrings: Group of three muscles on the back of the thigh Biceps femoris Semimembranosus Semitendinosus Gastrocnemius: Large calf muscle Soleus: Deeper calf muscle
Highlight: The iliotibial band is a thick band of fascia that runs along the outside of the thigh, from the hip to the knee. It can become tight when sitting for long periods.
Understanding the location and function of these major muscles is crucial for students studying the muscular system and its role in human movement and health.
Example: The trapezius muscle plays a significant role in posture and can contribute to tension headaches when tight or strained.
This comprehensive overview of the muscular system provides students with essential knowledge about muscle types, functions, and anatomical terms, serving as a valuable resource for health science education.
Types of Muscles and Their Characteristics
The muscular system consists of three main types of muscles, each with distinct functions and locations in the body:
- Skeletal muscles: Found attached to bones
- Cardiac muscles: Located exclusively in the heart
- Smooth muscles: Present in organs and blood vessels
Skeletal and cardiac muscles are both striated, meaning they have a striped appearance under a microscope.
Vocabulary: Sphincter muscles are special circular muscles that open and close to allow substance passage, such as the urethral sphincter for liquid waste and the anal sphincter for solid waste.
The muscular system exhibits several key characteristics:
- Contractability: Allows muscle tissue to pull or shorten
- Extensibility: The ability to stretch or expand
- Excitability: Capacity to respond to stimuli
- Elasticity: Ability to return to its original state
Highlight: Atrophy refers to the lack of muscle development or wasting away of muscle tissue.
Key terms related to muscle movement and function include:
- Abduction: Movement away from the midline
- Adduction: Movement toward the midline
- Aerobic: Requiring oxygen
- Anaerobic: Requiring no oxygen
- Agonist: Contracts muscle to cause movement
- Antagonist: Produces movement in the opposite direction of the prime mover
- Circumduction: Circular movement of a joint
- Extension: Increasing the angle between two bones
- Flexion: Decreasing the angle between two bones
Definition: Fascia is a thin, flexible band of connective tissue that holds, separates, or binds muscles.
Other important terms include:
- Insertion: Attachment point for skeletal muscle to bone after crossing a joint
- Origin: Attachment site for muscle to bone that does not move during contraction
- Isometric: Contraction of a muscle without joint movement
- Isotonic: Maintains constant tension as the muscle changes length
- Prime mover: Produces movement of a muscle in a single direction
- Synergist: Muscles that help support a joint
Vocabulary: Pronation refers to the rotation of the hand and forearm so that the palm faces downward, while supination is the opposite movement.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
