Marty Muscle  

and Friends

Marty Muscle has been looking to 

improve some of his facial muscles 

in order to impress the judges at his

body building competitions. One in

particular that he has been working 

on is the Corrugator Supercilii Muscle.

It The muscle is primarily used to show

emotion like suffering or frowning. It

 is also used to draw the eyebrows

 inward to form a “roof” that prevents 

high sun glare. It works by It moves 

          the skin that is superficial to the

             frontal bone and contacts to

             draw the eyebrow downward and inward. Its origin is at the 

                        Medial superciliary arch and inserts at the   Skin of                                                                         

                        the medial forehead. It gets it's name from the word

                     corrugare which means to wrinkle; super which means a                      

a                     above; and cilium which means eyelash. This muscle is a 

                      prime mover and is responsible for flexion.

Marty's friend Charlie is working on his Rectus 

Abdominis muscle to impress the ladies and the

judges. He is trying to explain to his friends what he 

needs to work on but they don't understand, so

instead he tells them that it is just a 6 pack. Rectus

stands for parallel to and that is there the muscles 

line up in the middle of the abdomen. He goes on

explaining the importance because they are involved

in heavy breathing, but the main function is to flex

the vertebral column. The only question that the other

guys have for Charlie is what group of muscles does 

this belong to?! And his response for that is the 

Antagonistic group. Continuing to explain that the

origin is located at the pubis and the insertion can 

be found at the end of the sternum and in the 

cartilage of ribs   5-7. The other guys now

understand the rectus abdominis and may work on 

improving theirs!

 Marty's buff friend Eddie has always bragged about 

his Trapezius Muscle. It is named for it's shape because 

it resembles a trapeziod. The superior part of the muscle

connects to the occipital bone and then goes along the 

vertebrae. The muscle connects laterally to the scapula. 

Its origin is at multiple places: the external occipital 

protuberance, the nuchal ligament, the medial superior

 nuchal line, and the spinous processes of vertebrae. It 

inserts at the posterior border of the lateral third of the 

clavicle, the acromion process, and spine of 

scapula. It is an antagonist muscle meaning it 

opposes or reverses the action of the prime 

mover but can also trade places with it.

The trapezius muscle adducts, 

depresses, and elevates the 

scapula. The muscle is used to 

move the scapula and support 

the arm.

When it comes to the Triceps Surae, look out for Bertha! She is

the sister of Marty and she has these muscles that will beat 

out anyone else's. Not only is this one big muscle, but Bertha tells

everyone that the name triceps tells us that there are three points. 

The Triceps Surae is made up of three different muscles and the 

origins of these are the distal femur and the posterior tibia. "Now

if those are the origins please tell us the insertions," one of the 

eager guys said. "Okay, well those are calcaneous, archilles 

tendon." All of these muscles work together to act upon the ankle 

by inducing plantar flexion and stabilizing the ankle. "These 

muscles sure do a lot than I thought they would," said Eddie. 

Bertha sure does do a good job of impressing the guys when it 

comes to lifting weights. "Did you guys know that this muscle is

made up of the gastrocnemius and the tibilias anterior 

antagonistic pairs?" "No we didn't!" "That is just one more thing

that Bertha know and we do not." "But we do know that they are

 very common in everyday activity such as walking, running, and 

jumping."

Curtis is a long time friend of Marty, and when it comes to lifting weights, this is one 

thing he doesn't want to pass up. Curtis has always been interested in muscles so 

he decided to learn a little about them first. He loved working on his arms, so he 

worked on those the most. He first learned the 

prefixes of the muscles and what they meant. Like Biceps 

Brachii meant two points of attachments. He tried to share

his knowledge with some other guys in his weight classes 

to help them understand what they were doing. He told 

them that the origin for the long head was at the 

supraglenoid tubercle of the scapula and the short end was 

at the hook-like structure on the lateral edge of the superior anterior portion of the 

scapula. He then went on to explain the insertion being located at   the 

posterior border of bicipital tuberosity of radius and bicipital aponeurosis to deep 

fascia and subcutaneous ulna. "These work together in the 

synovial hinge joint in the elbow, by providing the action of 

extension." "This is actually making sense!" These are both

Prime mover and Antagonistic muscles. "And let me guess, 

they are used when you do something like flex your arm?!"

"YES!" "You are correct"

Curtis then talks about the Triceps Brachii and how they are 

Antagonistic muscles with the Biceps Brachii. "Similar to the Biceps,

the triceps are made of three points of attachments instead of two."

The Long head origin is from infraglenoid tuberosity of the Scapula,

The Lateral head from posterior and lateral surface of the Humerus,

and the Medial head is from the lower posterior surface of the 

Humerus. "Just like the Biceps Brachii and every other muscle, the

Triceps Brachii have a point of insertion also." Their points are the 

upper posterior surface of the olecranon and the deep forearm 

fascia. These muscles act on the elbow but they also act on the 

scapula and the clavicle. "So both of these work together to act on 

joints and provide movement on the muscles?" "Yep, that is 

correct." They are an antagonistic pair and work together to do

 their everyday uses. 

Marty has always been impressed with

his friend Brad's ability to keep his hands 

steady when lifting weights. Brad claims

it's because of his impeccable Abductor

pollicis brevis muscle. This muscle gets its

name because it works to abduct the thumb.

Also, brevis means it is the shortest in a

series of muscles in the hand. Its origin is at 

the transverse carpal ligament, the scaphoid

and the trapezium. It inserts at the Radial 

base of proximal phalange of thumb and the 

thumb extensors. This muscle is responsible 

for abduction and extension of the thumb.It 

is, just like the trapezius, an antagonist 

muscle. Its primary function is to help with the 

opposition of the thumb which is a combination of 

actions that allows the tip of 

the thumb to touch the

 tips of other fingers. This 

muscle also works with 

the the carpometacarpal 

joint and the metacarp-

ophalangeal joint.

Marty's friends Mohammad has been working on his Abductor Hallucis Muscle so 

he can perfect his walk when he walks up to flex for the judges.

This muscle is named after it's movement: abduction. Hallucis comes from the 

word hallux, which is another word for the big toe. It's origin is at the tuberosity 

(elevation on bone) of the calcaneus and it's insertion is at the   medial aspect of 

base of 1st phalange of the big toe.

The primary bone this muscle acts on is 

the first phalange of the big toe. It is also

and antagonist bone and is responsible 

for flexion. This muscle helps support 

                          the arch in your foot 

                          and allows you to

                          flex your big toe.
