Summary
A rare anatomical variation of the intercostobrachial nerve (ICBN) was found, forming nerve loops with the third intercostal nerve. This finding is clinically significant for surgeries involving the axilla.
Area of Science:
- Anatomy
- Surgical Anatomy
Background:
- The intercostobrachial nerve (ICBN), a cutaneous branch of the second intercostal nerve, is crucial for sensation in the upper limb and axilla.
- Variations in the ICBN can impact surgical outcomes, particularly in axillary procedures.
Purpose of the Study:
- To document and describe a rare anatomical variation of the intercostobrachial nerve (ICBN).
- To highlight the clinical significance of this variation for surgeons and radiologists.
Main Methods:
- Observation during routine dissection classes for first-year medical students.
- Detailed anatomical description and documentation of the nerve variation.
Main Results:
- A rare anatomical variation where the ICBN formed aberrant nerve loops with branches of the third intercostal nerve.
- These loops likely supplied the floor of the axilla and proximal arm.
Conclusions:
- This case report details a significant anatomical variation of the ICBN.
- Understanding such variations is vital for preventing sensory deficits during axillary lymph node dissections and mammary gland surgeries.

3.2K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:12Arteries of the Upper Limbs
2.7K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

01:16Accessory Structures of the Skin: Hair and Hair Follicles
5.0K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

01:20Sympathetic Pathways: Sympathetic Chain Ganglia
6.8K
The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...
