Summary
Nail abnormalities like linear erythronychia originate from the nail bed, specifically affecting nail bed stem cells (NBMSC). These stem cells normally form the nail plate but can manifest diverse appearances when stimulated.
Area of Science:
- Dermatology
- Cell Biology
- Nail Biology
Background:
- Dermatologic literature documents nail abnormalities, including linear erythronychia and onychomatricoma, which involve the nail bed.
- These conditions reflect the specific cellular behavior within the nail bed's matrix.
Purpose of the Study:
- To elucidate the cellular origins and mechanisms underlying nail bed abnormalities.
- To understand the role of nail bed matrix cells (NBMSC) in the manifestation of diverse nail appearances.
Main Methods:
- Review of dermatologic literature on nail bed abnormalities.
- Analysis of the cellular processes involving nail bed matrix stem cells (NBMSC).
Main Results:
- Nail abnormalities involving the nail bed are linked to the behavior of nail bed matrix stem cells (NBMSC).
- The epidermis's varied clinical presentations depend on stimuli impacting these NBMSC.
- NBMSC are stem cells that migrate distally, covering dermal ridges homologous to fingerprints.
Conclusions:
- The nail bed matrix stem cells (NBMSC) are central to the development of various nail abnormalities.
- Understanding NBMSC behavior is key to diagnosing and potentially treating conditions like linear erythronychia.

01:05Accessory Structures of the Skin: Nails
1.7K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

01:16Accessory Structures of the Skin: Hair and Hair Follicles
2.2K
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...

01:19Bones of the Upper Limb: Humerus
3.2K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

01:09Bones of the Upper Limb: Radius
2.2K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

01:15Bones of the Upper Limb: Ulna
2.1K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

01:21Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
