The ulnar nerve originates from C8-T1 nerve roots which form the medial cord of the brachial plexus. The ulnar nerve runs down the hand where it passes behind the medial epicondyle of the humerus at the elbow. The ulnar nerve doesn’t give branches in the axilla or in the upper arm. It starts giving muscular and cutaneous branches in the upper forearm and hand. After the ulnar nerve passes behind the medial epicondyle, it enters the forearm between the two heads of the flexor carpi ulnaris muscle. The ulnar nerve may become compressed or irritated as it passes behind the medial epicondyle. The ulnar nerve travels through the cubital tunnel that runs under the medial epicondyle. The nerve gives branches to the flexor carpi ulnaris and medial half of flexor digitorum profundus

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
