Ramo comunicante entre los nervios mediano y ulnar en el antebrazo humano

Int. j. morphol; 41 (1), 2023
El ramo comunicante mediano-ulnar (RCMU) es la conexión que se origina del nervio mediano (NM) o alguno de sus ramos, para unirse al nervio ulnar (NU) en el antebrazo humano. Cuando este RCMU está presente, determina una prevalencia que oscila entre un 8 % y un 32 %, de tal manera los axones del NM se ...

The posterior interosseous nerve at the proximal forearm: anatomical study and clinical correlation

Int. j. morphol; 41 (1), 2023
SUMMARY: The deep branch of the radial nerve (DBRN) runs through the radial tunnel, which is a muscle-aponeurotic structure that extends from the humeral lateral epicondyle to the distal margin of the supinator muscle (SM). The Posterior Interosseous Nerve (PIN) originates as a direct continuation of the...

Nervio interóseo posterior: origen, localización y trayecto nervioso: una revisión

Int. j. morphol; 39 (6), 2021
RESUMEN: El nervio interóseo posterior (NIP) ha sido utilizado como sinónimo ocontinuación inmediata del ramo profundo del nervio radial (RPNR) al emerger en el compartimiento posterior del antebrazo. Su origen tampoco es claro, describiéndose como nervio interóseo posterior a su trayecto proximal, ...

Anastomosis Patterns between the Median and Ulnar Nerves in the Upper Limbs

Arq. bras. neurocir; 40 (2), 2021
There are four types of anastomoses between themedian and ulnar nerves in the upper limbs. It consists of crossings of axons that produce changes in the innervation of the upper limbs, mainly in the intrinsic muscles of the hand. The forearm has two anatomical changes – Martin-Gruber: branch originatin...

The course and branching patterns of the superficial branch of radial nerve in foetuses and clinical significance

Int. j. morphol; 37 (4), 2019
Knowing the anatomical, topographic and morphometric properties of the superficial branch of the radial nerve (SBRN) in the forearm and the dorsum of the hand is important for minimizing nerve damage. The purpose of this study is to evaluate the anatomical and morphometric properties of SBRN in foetuses....

Trayecto inusual del nervio ulnar en el tercio proximal del antebrazo

Int. j. morphol; 37 (3), 2019
Se presenta un caso de variación del trayecto habitual del nervio ulnar, en los primeros 12 cm proximales del antebrazo, con la descripción de las estructuras anatómicas en relación con esta variación anatómica. Esto debe ser tenido en cuenta ante la ausencia de hallazgo del nervio ulnar al momento...

Communicating branches between the median and ulnar nerves: proposal for inclusion in terminologia anatomica

Int. j. morphol; 37 (3), 2019
The ulnar and median nerves are widely distributed, innervating the muscles of the forearm and hand. In the latter, it also registers the sensitivity of a significant part of the skin. A series of communicating branches (CB) is described on the path of these nerves, including: 1) the Martin-Gruber commun...

Anatomical study of the transfer of flexor digitorum superficialis nerve branch of median nerve to restore wrist extension and forearm pronation

Einstein (Säo Paulo); 17 (3), 2019
Abstract Objective To analyze the anatomical variations of the innervation of the flexor digitorum superficialis muscle and to determine if the branch of the median nerve that supply this muscle is connected to the branches to the extensor carpi radialis brevis and the pronator teres muscles, without t...

Anatomical variations of the caudomedial antebrachial muscles in the crab-eating fox (Cerdocyon thous)

Int. j. morphol; 36 (4), 2018
The crab-eating fox (Cerdocyon thous) is a wild canid distributed in South America, which is susceptible to traumas caused by captors, accidents on roads, and traps. Due to these events their thoracic limbs can be involved at the level of the forearm, therefore, knowledge of the gross anatomy of its musc...

Inervación del músculo flexor superficial de los dedos

Int. j. morphol; 36 (2), 2018
La inervación del músculo flexor superficial de los dedos (FSD) es controversial. Diversos autores describen que los ramos de este músculo surgen independiente o desde un tronco común que proviene desde el nervio mediano, dentro de la región cubital. Otras descripciones señalan la presencia de ramo...
