Elbow Joint Model Q & A

Elbow Joint ModelWhat is the typical size for an elbow joint model?

The elbow joint model is one of the many models that come in a variety of sizes. If you elect to have the simple or basic elbow joint only on the model the length of the model itself is 8.5 inches. The base is the standard 61.5in x 5in x 1in, which is ideal for storing on a shelf, counter or desk.  The elbow joint that includes the forearm and the hand is much longer, measuring in at 19 inches in length. Both options are very streamlined and compact, easy to store and move for classroom use or in patient rooms.  The full arm elbow models has the arm slightly bent to provide stability to the model and also allow easy viewing from a variety of different angles.

Are there different options in elbow joint model styles that provide additional detail over just the basic joint?

The basic human elbow joint model is great for teaching and working with students and patients alike. Although it is just the bone structure and corresponding ligaments it is specific enough for clearly demonstrating movement, muscle or ligament problems or fractures of the joint to patients. It is also perfect for anatomy students to use to learn how the hinge joint works.

Beyond the basic elbow joint model, there is the muscled elbow model. This model includes the musculature at the top of the elbow, clearly defining how those muscles work. Models will include the ligaments, the bones of the lower arm, wrist and hand as well as the major nerves that run from the upper arm through to the wrist. This type of model is good for both work with patients as well as classroom study and helps to show the working of the entire arm.

Where could I use an elbow joint model in a college level biology or general science class?

The elbow joint model is a great addition to any classroom because it appears so simple but is actually a very complex interconnection of the upper and lower arms. With major nerves running down the arm and through the elbow clearly visible in the model that reasons why the elbow can be so painful at times is very evident. Biology, science or anatomy classes can use the model to supplement the lecture as well as viewing pictures in their textbook.

Models with labeled cards that correspond to the features on the elbow or arm are a great way for students at any level to self-test and review. The cars can be removed during the review, allowing students to attempt to identify the various components of the joint. Students can then self-check their work by flipping up the card. This saves instructor time and also gives students a more active way to study anatomy. The models can also be used during examinations where numbers or letters are taped to the specific muscles, tendons, nerves or bones with the students required to supply the correct name for the feature. Elbow models can be used along with other anatomical and disease models for a thorough study of human anatomy.
