'''Artistic Gymnastics''' is a discipline of [[gymnastics]] in which athletes perform short routines (ranging from approximately 30 to 90 seconds) on different apparatus, with less time for vaulting. The sport is governed by the [[Fédération Internationale de Gymnastique]] (FIG), which designs the Code of Points and regulates all aspects of international elite competition. Within individual countries, gymnastics is regulated by national federations like [[USA Gymnastics]] (USAG) in the United States.

==History==
The '''arachnoid trabeculae''' are delicate, web-like structures that are part of the [[arachnoid mater]], one of the three layers of the [[meninges]] that cover the [[central nervous system]]. These trabeculae extend through the [[subarachnoid space]], connecting the arachnoid mater to the underlying [[pia mater]].
Artistic gymnastics is one of the oldest forms of gymnastics and has its roots in ancient civilizations. However, it was not until the late 19th century that it began to take its modern form. The first modern Olympic Games in 1896 featured men's artistic gymnastics. Women's artistic gymnastics was added to the Olympics in 1928.


==Apparatus==
=== Structure ===
In artistic gymnastics, athletes compete on different apparatus. Men compete on six apparatus: [[Floor Exercise]], [[Pommel Horse]], [[Rings]], [[Vault (gymnastics)|Vault]], [[Parallel Bars]], and [[Horizontal Bar]]. Women compete on four: [[Vault (gymnastics)|Vault]], [[Uneven Bars]], [[Balance Beam]], and [[Floor Exercise]].


===Men's Apparatus===
The arachnoid trabeculae are composed of [[collagen]] fibers and [[fibroblasts]], which provide structural support and maintain the spacing between the arachnoid and pia mater. This spacing is crucial for the circulation of [[cerebrospinal fluid]] (CSF) within the subarachnoid space. The trabeculae are most dense in areas where the brain is subject to movement, providing additional support and stability.
* '''Floor Exercise''': Gymnasts perform a routine on a 12m x 12m spring floor.
* '''Pommel Horse''': Routines involve circular movements of the legs and body, with both hands on the horse.
* '''Rings''': Gymnasts perform swings, strength elements, and holds, requiring great strength and control.
* '''Vault''': Athletes sprint down a runway and perform a vault over a vaulting table.
* '''Parallel Bars''': Routines consist of swings, flights, and balances on two parallel bars.
* '''Horizontal Bar''': Gymnasts perform swings, release skills, and dismounts around a single bar.


===Women's Apparatus===
=== Function ===
* '''Vault''': Similar to men, but the performance and scoring criteria differ.
* '''Uneven Bars''': Gymnasts perform routines moving between two bars of different heights.
* '''Balance Beam''': Athletes perform a routine on a beam only 10cm wide.
* '''Floor Exercise''': Similar to men but includes dance elements.


==Scoring==
The primary function of the arachnoid trabeculae is to maintain the subarachnoid space, allowing for the free flow of CSF. This fluid acts as a cushion, protecting the brain and spinal cord from mechanical injury. Additionally, the trabeculae help to anchor the brain within the cranial cavity, preventing excessive movement that could lead to injury.
The scoring in artistic gymnastics is based on the [[Code of Points (gymnastics)|Code of Points]], a comprehensive rulebook that outlines the scoring system. Scores are divided into two parts: the difficulty score (D-score) and the execution score (E-score). The D-score is based on the difficulty of the elements the gymnast performs, and the E-score is based on how well the gymnast executes the routine, with deductions for errors.


==Major Competitions==
=== Clinical Significance ===
The most prestigious competitions in artistic gymnastics are the [[Olympic Games]], the [[World Championships (gymnastics)|World Championships]], and the [[World Cup (gymnastics)|World Cup]] series. National championships and continental championships, such as the European Championships and the Pan American Games, also hold significant importance.


==Notable Gymnasts==
Disruption or damage to the arachnoid trabeculae can lead to various medical conditions. For example, [[subarachnoid hemorrhage]] can occur if blood vessels within the subarachnoid space are ruptured, potentially affecting the trabeculae. In some cases, arachnoid trabeculae may become thickened or scarred, leading to conditions such as [[arachnoiditis]], which can cause chronic pain and neurological deficits.
Many gymnasts have left a significant mark on the sport. Notable names include [[Simone Biles]] from the United States, who is considered one of the greatest female gymnasts of all time, and [[Kohei Uchimura]] from Japan, often regarded as the greatest male gymnast in history.

Arachnoid Trabeculae

The arachnoid trabeculae are delicate, web-like structures that are part of the arachnoid mater, one of the three layers of the meninges that cover the central nervous system. These trabeculae extend through the subarachnoid space, connecting the arachnoid mater to the underlying pia mater.

Structure

The arachnoid trabeculae are composed of collagen fibers and fibroblasts, which provide structural support and maintain the spacing between the arachnoid and pia mater. This spacing is crucial for the circulation of cerebrospinal fluid (CSF) within the subarachnoid space. The trabeculae are most dense in areas where the brain is subject to movement, providing additional support and stability.

Function

The primary function of the arachnoid trabeculae is to maintain the subarachnoid space, allowing for the free flow of CSF. This fluid acts as a cushion, protecting the brain and spinal cord from mechanical injury. Additionally, the trabeculae help to anchor the brain within the cranial cavity, preventing excessive movement that could lead to injury.

Clinical Significance

Disruption or damage to the arachnoid trabeculae can lead to various medical conditions. For example, subarachnoid hemorrhage can occur if blood vessels within the subarachnoid space are ruptured, potentially affecting the trabeculae. In some cases, arachnoid trabeculae may become thickened or scarred, leading to conditions such as arachnoiditis, which can cause chronic pain and neurological deficits.

Research

Recent studies have focused on the role of arachnoid trabeculae in the pathophysiology of hydrocephalus, a condition characterized by an abnormal accumulation of CSF. Understanding the mechanical properties and biological functions of the trabeculae may provide insights into new therapeutic approaches for managing this condition.
