Finger of the Large Hand (Pollex, Plural Pollices)

Finger of the Great Hand (Pollex, Plural Pollices): anatomy and functions

The thumb of the hand, also known as Pollex, is the thumb of the hand and plays an important role in the anatomy and function of the human hand. In this article we will take a closer look at the anatomy and functions of the thumb.

Anatomy of the thumb

The thumb of the Great Hand consists of two phalanges, two joints and a large number of muscles, tendons and nerves. It is connected to the hand by five tendons that pass through channels in the hand. Each of these tendons is controlled by a separate muscle, allowing the thumb to move in all directions.

Functions of the thumb of the hand

The thumb of the thumb plays an important role in many daily human activities. It is used to grasp and hold objects and to perform complex movements such as playing musical instruments, writing, and drawing.

In addition, the thumb finger has a unique function that other fingers do not have - it can meet other fingers of the hand, which is called opposition. The opposition finger of the thumb allows a person to hold and manipulate objects with greater precision and control.

Pathologies of the thumb

Although the thumb is an important part of the hand, it can also be susceptible to certain pathologies and injuries. Some of the most common pathologies of the thumb include arthritis, tenosynovitis, and deformities such as finger squint.

In conclusion, the thumb plays an important role in the anatomy and function of the human hand. It allows us to perform various activities in daily life and also has a unique opposition function that gives us great control and precision when handling objects. However, like any other part of the body, the thumb can be subject to pathologies and injuries, so it is important to monitor its condition and consult a doctor if there are any changes in its function or structure.

Thumb (Pollex, Plural Pollices): Anatomy and Role in the Human Body

In the human body, each finger has its own unique structure and function. One of the most important fingers is the Finger of the Great Hand, also known as Pollex (Latin) or Pollices (plural). The thumb of the Great Hand has special anatomical features and plays an important role in human daily activities.

Anatomy of the Thumb:
The thumb of the Great Hand consists of three phalanges (proximal, middle and distal) and the interphalangeal joint, which ensures its mobility. This finger has a distinctive appearance because its proximal phalanx connects to the large bone of the wrist, called the radiocarpal bone. This anatomical feature makes the Thumb Finger more flexible and stronger than the other fingers.

Functions of the Thumb:
The thumb of the Great Hand plays a key role in many everyday activities and complex manipulations. Here are some important functions that the Thumb Finger performs:

1. Grasping and Holding: Thanks to its anatomy, the thumb allows us to grasp and hold objects. This ability is one of the main differences between humans and other animal species and plays an important role in performing various tasks such as writing, playing musical instruments, manipulating tools and much more.

2. Precision and Sensitivity: The Thumb Finger has a high degree of precision and sensitivity. Thanks to the large number of nerve endings located in the fingertips, it is able to sense the smallest details and distinguish the textures of surfaces. This allows us to perform complex tasks that require fine motor skills and tactile perception.

3. Hand Support: The thumb of the thumb plays an important role in supporting the architecture of the hand and ensuring its stability during various movements. It provides support for the rest of the fingers and helps maintain balance as the hand contracts and expands.

Some Disorders and Injuries:
The thumb is also susceptible to various disorders and injuries that can limit its functionality and cause pain. Some of the most common problems include arthritis, ligament injuries, sprains and fractures.

In conclusion, the Finger of the Great Hand (Pollex, Plural Pollices) is an important part of the anatomy of the human body. Its special structure and function enable it to perform a wide range of tasks involving grasping, holding and fine manipulation. Proper functioning of the Thumb of the Hand greatly influences our ability to interact with the world around us and achieve high motor precision.

The thumb of the hand or Pollex is one of the five fingers of the hand that is located in the palm and is the longest and most powerful finger in this area. In anatomy, it is also known as the thumb and has several important functions for our body.

The Greater Manus finger has three main parts: the nail phalanx, the middle phalanx, and the distal phalanx. The nail phalanx is the very tip of the finger where the nail is located, and the middle phalanx is the widest part of the finger. The distal phalanx, which is the longest part of the finger, is located at the bottom of the finger and is responsible for its mobility and flexibility.

The functions of the thumb of the Hand include using it as a tool for grasping and holding objects, and for creating various movements and actions in the hand. It is also involved in the formation of various gestures and facial expressions, such as raising a hand up in greeting or pointing at something.

In addition, the thumb of the Great Hand plays an important role in our ability to write and draw. It can be used to support other fingers while writing and to ensure precision and accuracy when drawing.

However, like any other finger, the Big Hand Finger can be susceptible to various diseases and injuries. For example, inflammation or infection can lead to pain and swelling, while fractures and dislocations can limit its mobility and functionality.

In conclusion, the Thumb of the Hand is an important element of our hand and plays a key role in performing various functions and actions. Its health and mobility can affect our ability to work, socialize, and express ourselves. Therefore, it is important to take care of the health of this finger by regularly performing exercises to strengthen it and prevent injury.
