intercostobrachial

The size of the intercostobrachial nerve is in inverse proportion to that of the medial brachial cutaneous nerve.

IX. Neurology. 6c. The Thoracic Nerves 1918

The first intercostal nerve as a rule gives off no lateral cutaneous branch; but sometimes it sends a small branch to communicate with the intercostobrachial.

IX. Neurology. 6c. The Thoracic Nerves 1918

The lateral cutaneous branch of the second intercostal nerve does not divide, like the others, into an anterior and a posterior branch; it is named the intercostobrachial nerve (Fig. 816).

IX. Neurology. 6c. The Thoracic Nerves 1918

A second intercostobrachial nerve is frequently given off from the lateral cutaneous branch of the third intercostal; it supplies filaments to the axilla and medial side of the arm.

IX. Neurology. 6c. The Thoracic Nerves 1918

In other cases the intercostobrachial is of large size, and takes the place of the medial brachial cutaneous, receiving merely a filament of communication from the brachial plexus, which represents the latter nerve; in a few cases, this filament is wanting.

IX. Neurology. 6b. The Anterior Divisions 1918

In some cases the medial brachial cutaneous and intercostobrachial are connected by two or three filaments, which form a plexus in the axilla.

IX. Neurology. 6b. The Anterior Divisions 1918

It passes through the axilla, at first lying behind, and then medial to the axillary vein, and communicates with the intercostobrachial nerve.

IX. Neurology. 6b. The Anterior Divisions 1918

In its course it crosses behind, and communicates with, the intercostobrachial.

IX. Neurology. 6b. The Anterior Divisions 1918

There are some important nerves, however, in this situation, viz., the long thoracic nerve, descending on the surface of the Serratus anterior, to which it is distributed; and the intercostobrachial nerve, perforating the upper and anterior part of this wall, and passing across the axilla to the medial side of the arm.
