3 天之前 · Five major nerves extend from the brachial plexus into the arm: the axillary, musculocutaneous, median, radial, and ulnar nerves. Each of these nerves carries information in the form of nerve impulses to and from a particular region of the arm and hand.

The brachial plexus is a group of nerves that control the muscles of the shoulder, arm, forearm, and hand. These same nerves also provide sensations (feeling) of the whole upper limb. There are five components of the brachial plexus: roots, trunks, divisions, cords, and branches.

There are 6 topics covered in the nerves of the upper limb, an overview of the brachial plexus and a more in-depth look into it’s 5 main branches: axillary, musculocutaneous, median, radial, and ulnar nerves.

2025年2月4日 · Arm nerve pain is a common problem caused by pressure or irritation of one of the arm nerves, anywhere along its path from the neck to the hand. Nerve damage typically causes a stabbing, shooting or burning pain in the arm and may be accompanied by tingling or decreased sensation in the arm or hand.

2024年3月13日 · The nerves found within the arm are terminal branches of the brachial plexus and serve to innervate muscles of the upper extremity and transmit sensory information to the higher processing centers of the brain.

2023年11月3日 · In this page, we are going to discuss the arteries, veins and nerves of each upper limb region; the shoulder, arm, forearm and hand. All together these form the neurovascular compartment of the upper limb. The nerves of the upper limb originate from the brachial plexus and include the musculocutaneous, axillary, median, radial and ulnar nerves.

2015年11月13日 · This article will focus on the five terminal nerve branches of the brachial plexus which supply the upper limb. These are the musculocutaneous nerve, the axillary nerve, the radial nerve, the median nerve and the ulnar nerve. We will cover their anatomy and function, as well as the clinical features you would expect to find with a nerve injury.

To give you a better understanding of the nerves of the arm, we have included a diagram that highlights the main nerves and their pathways. This invaluable resource will help you visualize the intricate network and understand how each nerve contributes to the overall functioning of the arm.

2016年2月8日 · Musculocutaneous nerve: This nerve contributes to muscles that bend the elbow and provides sensation to the forearm. Axillary nerve: This nerve provides signals to muscles that help raise the arm. It travels deep around the shoulder.

2023年7月25日 · The nerves of the arm are supplied by one of the two major nerve plexus of the human body, the brachial plexus. The upper extremity begins at the shoulder joint. This joint is commonly referred to as a ball-and-socket joint, although it is more correctly described as a ball-and-saucer joint.
