This Practical will include…

Upper Body Muscles (1-40)

•name/action

• cats

• bodybuilder photos

• cadaver

• purple arm

The Brain and Spinal Cord

• sheep and human brains and spinal cord model

Cranial Nerves

• olfactory, optic, oculomotor, trochlear, trigeminal, abducens, auditory, vagus (in the cat) and accessory

Brachial Plexus

Be sure to view the Sample Practical Video (No. 2), available for home loan in the library or for viewing in the IMC.

Also don’t forget to bring a probe and gloves to the practical!

 

 

To remember these actions, you could think of yourself sleeping on your stomach. When you sleep, you dream of a CASTLe, but when you awake, it  will FADE Away. (That is so Funny!)

 

 

Muscle names:

C = Clavo-trapezius

A = Acromio-trapezius

S = Spino-trapezius

T= LevaTor scapulae

Le = Latissimus dorsi

 

Muscle actions in order with the mnemonic above:

F = Flex head laterally

A = Adducts scapula

D = Depresses scapula

E = Elevates scapula

 

Away = Adducts Humerus (That is so funny! = to remember it is the humerus)

 

1 – Clavo-trapezius

2 – Acromio-trapezius

3 – Spino-trapezius

4 – Levator scapulae

5 – Latissimus dorsi

Here is another trick, tip, learning device for Anatomy. It focuses on the Upper Leg muscles. I call it my Thigh-Burger. This is looking at the anterior side of the leg. The top of the bun would be medial, and the bottom of the bun Lateral. If I was laying on my bum, I would be in a lateral position.

Okay. I will story this up with a few actions, as this is what I need to recall.

First its ABout the bun, we have our bottom bun (Tensor Fasciae Latae/abducts thigh). We will ADd the top bun as we know we are going to put much inside of it and we don’t want it to fall out (Gracilis/adducts thigh). There are four (Quadriceps/flex and extend) important things in our Thigh-Burger.

1.) On the bottom of the bun we are going to include some nice dressing from Vastus, a lot (Vastus Lateralis) to the bottom bun with,

2.) a little inner drop of Vastus Intermedius to help EXtend our dressing. 

3.) We are also going to add it to the top bun (the Medial side/Vastus Medialis), because we want it on either side of the,

4.) main meat (Rectus Femoris).

But when we put the buns on the burger we think, Wait! I want more than that!

We take the top off and all the top Vastus (Medialis) stuck to the Rectus Femoris. But that’s okay, we will just ADD a few more items between the Vastus Medialis and the Top bun (Gracilis).

First, on top of the Vastus Medialis covered Rectus Femoris, we will place the lettuce (Adductor Longus), then some nice Tomatoes, but the are a little small – (Adductor Brevis), and we can’t over look a big, huge grouping of Magnificent onion rings (Adductor Magnus).

Okay, but how do we hold it all together so it won’t fall apart? We put the sword (Sartorius) over across it all to hold it together! (Sartorius/flexes and laterally rotates).

Can you eat/beat that?

 

Scapula Muscles

This is a story. We are applying a soft-ball type of analogy, though I don’t play baseball, so just play along with me. Move your arm with the story!

 

In order to pitch the ball, we will use the Supraspinatus muscle to abduct our arm away from our body, then using the Infraspinatus, we will laterally rotate our arm for the pitch, but wait, the sub-pitcher wants in….Subscapularis likes to pitch different, he will use a Medial rotation, and then of course using our last muscle on the scapula bone, our Teres Major will adduct, bring our arm back in. Sometimes even extending it if the sub was used.

 

So that’s the story, they all work the humerus.

 

The Supraspinatus Abducts the humerus

The Infraspinatus Laterally rotates the humerus

But wait the sub pitcher wants in and,

Subscapularis Medially rotates the humerus

Teres Major brings it back in, Adducts (or even extends)

I’m taking Anatomy at the community college in Antelope Valley. It’s a great course and I am always amazed they allow me in it. I suppose it appeals to the game player in me. The putting together a puzzle. ..Well, anyways I thought I would start posting any tricks I come up with to help with the memorization of names and processes. It also allows me to draw a little. The last practical was on upper body muscles and actions. I have 2 which will help with seven muscles and their actions.

 

Deltoids

There are three sections that unite to create the Greek triangle. The names of the three specify their origins. Starting from the back: Spino-deltoid, Acromio-deltoid, and Clavo-deltoid. They all unite to a tendon attaching to the deltoid tuberosity on the humerus.

 

In this order from back to front the three sections spell S-A-C.

Their actions create this phrase: Easy AB For deltoids!

Spino-deltoid is Easy or Extends, Acromio- is AB or Abducts, and Clavo- is for Flexes. Their actions are all on the humerus.

                                                     Easy     AB       For       Deltoids!
