Forearm Extensor Muscles - Origins, Insertions, and Actions, with Video Presentation

The following is information on the extensor muscles of the forearms. These videos were produced to help students of human anatomy at Modesto Junior College study their anatomical models.

They are done with models showing the muscular structure of the arm.

The following two videos present an overview of the major flexor muscles of the forearm, which are the muscles of the posterior compartment.

Each video is followed by information on the origin, insertion, and actions of each muscle covered in the video.

Forearm Flexor Muscles - Origins, Insertions, and Actions, with Video Presentation

These videos were produced to help students of human anatomy at Modesto Junior College study their anatomical models.

They are done with models showing the muscular structure of the arm.

The following two videos present an overview of the major flexor muscles of the forearm, which are the muscles of the anterior compartment. These muscles not only are responsible for flexion of the wrist, but are also the extrinsic muscles of the hand, responsible for much its gripping strength.

Each video is followed by information on the origin, insertion, and actions of each muscle covered in the video.

What are the Main Muscles Active During the Deadlift?

See a full description of the lifting technique for the deadlift. The deadlift is actually a total body exercise. In other words, to some extent, every muscle in the body becomes involved. It would be impossible to accurately outline the contribution of every single muscle group during the deadlift, especially since this can change as the weight on the bar is increased and the lift becomes more challenging. However, comparisons can be made to another core lift, the back squat. And the main active muscles groups can be listed.

What is Adaptive Muscle Shortening?

A muscle can change its functional resting length to adapt to the length at which the muscle is habitually used or positioned. This is called adaptive shortening.

Adaptive Shortening Example

An example of this type of muscle shortening is the shortening of the iliopsoas (one-joint hip flexors) in individuals who are confined to a wheelchair or who must spend most of their day sitting. Another example is the wearing of high-heeled shoes, which can cause adaptive shortening of the soleus since the foot must remain in plantar flexion. Adaptive shortening of muscles causes postural distortions which result in a further imbalance between opposing pairs of muscle.

Muscle Shortening Causes

Adaptive Shortening is muscle tightness caused by a muscle being forced to remain in a shortened position for a prolonged period of time, being unable to lengthen due to the relaxation of the antagonist group.
