Anatomy Basics: Muscles of the forearm, flexor muscles

Muscles of the arm
As we continue our look at the muscles of the arm we will next look at some of the muscles found in the forearm. One of the first things you may notice is that there a many more muscles in the forearm than the upper arm. This makes sense once we understand how we move the fingers and hand. Though there are some muscles in the forearm that move the arm, many of the muscles located there move the fingers and thumb or the hand at the wrist. Since there are several muscles to discuss I thought I would break them into groups based on their actions.

Today, we will look at a group of the muscles found in the forearm that flex the hand and fingers. We will look at where these muscles attach to the skeleton and describe how these muscles move the arm.

Let's begin.

Anatomy Basics: Muscles of the upper arm

Now that I am finding the format I like to follow for the anatomy basics posts I want to revisit the anatomy of the arm to present it a little more clearly. I am looking to for ways approach the anatomy of the human form that assist us in our drawing. Looking at the shapes and location of the muscles is a good place to start.

Today, we will look at a few of the muscles found in the upper arm, including the biceps, triceps, brachialis, and coracobrachialis. We will look at the attachment points of the muscles and how these muscles move the arm. 

Let's begin.

Anatomy Basics: The Muscles of the Back

A charcoal drawing of the shoulder and back.
It has been a while since I have done an anatomy basics post and it is time to do another. As mentioned in the last anatomy basics post, the next subject is going to be about the muscles of the back.

Today, we will look at a few of the muscles of the back. We will look at the location of each muscle, including the origin and insertion points. We will also describe each muscle's action.

Let's start from the top and work our way down.

Painting Basics: Limited Palette

In the previous post about color palettes, I showed examples of a basic or limited palette. I thought I would continue this topic by demonstrating how to create a wide range of colors using a palette of just a few colors. This can help us gain a better understanding of mixing color and how the pigments work together.

Today, I will use a limited color palette I teach my students to show that most colors can be mixed from just four paints.
