Plexal point

Plexal Point

The Plexal Point is a term used in anatomy to describe a specific location within the brachial plexus, a network of nerves that send signals from your spinal cord to your shoulder, arm, and hand. The plexal point is where the lateral and medial cords of the brachial plexus join to form the median nerve.

Etymology

The term "plexal" is derived from the Latin word "plexus", which means "braid" or "network". This is a fitting description for the complex network of nerves that make up the brachial plexus.

Anatomy

The brachial plexus is divided into five sections: the roots, trunks, divisions, cords, and branches. The plexal point is located in the cords section, specifically where the lateral and medial cords join to form the median nerve. This nerve is responsible for the majority of the motor and sensory function in the hand.

Clinical Significance

Damage to the plexal point can result in a variety of conditions, including carpal tunnel syndrome, median nerve palsy, and pronator syndrome. These conditions can cause symptoms such as pain, numbness, and weakness in the hand and arm.
