Which nerve travels between the olecranon and medial epicondyle of the humerus?
Which nerve travels between the olecranon and medial epicondyle of the humerus?
Cubital tunnel syndrome is a peripheral neuropathy due to chronic compression or repetitive trauma of the ulnar nerve at the elbow between the medial epicondyle of the humerus and the olecranon process of the ulna.
What nerve passes through the medial aspect of the olecranon?
In the elbow, the ulnar nerve passes behind the medial epicondyle of the humerus and is medial to the ulnar collateral ligament and olecranon.
What nerve is near the medial epicondyle?
the ulnar nerve
One of three main nerves in the arm, the ulnar nerve travels from the neck, through a tunnel of tissue (cubital tunnel) that runs under a bump of bone (medial epicondyle) at the inside of your elbow.
What Innervates the medial elbow?
The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest in the human body unprotected by muscle or bone, so injury is common….

What does the musculocutaneous nerve innervate?
The musculocutaneous nerve innervates the three muscles of the anterior compartment of the arm: the coracobrachialis, biceps brachii, and brachialis. It is also responsible for cutaneous innervation of the lateral forearm.
Where does the ulnar nerve travel?
Description. The ulnar nerve then travels alongside the ulnar bone of the forearm into the wrist. As the nerve descends into the forearm, it stays medially above the flexor digitorium profundus and under the flexor carpi ulnaris giving branches to these muscles.
Where is the brachial plexus nerve located?
The brachial plexus is a bundle of nerves that stems from nerve roots in the cervical (neck) and upper trunk (torso) sections of the spinal cord (C5-T1), creating a network that connects to the nerves in the arm.
What does median nerve innervate?
The median nerve predominantly provides motor innervation to the flexor muscles of the forearm and hand as well as those muscles responsible for flexion, abduction, opposition, and extension of the thumb.
Does musculocutaneous nerve innervate the elbow joint?
Course and innervation As it descends it innervates both of these muscles. After giving small branch to the humerus and articular branches to the elbow joint it pierces deep fascia and emerges lateral to biceps brachii. It then continues as the lateral cutaneous nerve of the forearm.
What is Intercostobrachial nerve?
The intercostobrachial nerve (ICBN) is a cutaneous nerve that provides sensation to the lateral chest, medial aspect of the upper arm, and the axilla.
