El término cuerpo amigdaloide en la terminología médica / The term amygdaloid body in medical terminology

RESUMEN: En terminología médica el término amígdala cerebral es utilizado para denominar a la estructura que según la Terminologia Neuroanatomica y Terminologia Anatomica se conoce como cuerpo amigadaloide, la cual está constituida por diversos núcleos y es responsable de las emociones, el comportamiento, regulación de la ansiedad, la agresión, el miedo, la memoria emocional, la cognición social y las respuestas al estrés. Siendo la amígdala cerebral una estructura tan importante el objetivo de este estudio fue: analizar el significado del término amígdala cerebral en la Terminologia Neuronatomica y en la Terminologia Anatomica y contrastar si el origen de sus raíces greco latinas concuerdan con la función de esta estructura acorde con los requerimientos de la FIPAT. Para ello se consultó los diccionarios de la Lengua Española, Diccionario DGE Griego Español, Diccionario VOX Griego Español, Diccionario Médico, Biológico, Histológico y Etimológico de la Universidad de Salamanca y Diccionario de Términos Médicos de la Real Academia Nacional de Medicina, así como algunos artículos y libros clásicos de anatomía. Los resultados indicaron que el término amígdala tiene el mismo significado en griego como en latín, en donde ἀμυγδαλέα, ἀμυγδαλέας (pr. amygdaléa, amygdaléas) es el árbol del almedro y ἀμυγδάλη, ἀμυγδάλης (pr. amygdále, amygdáles) significa almendra. Conociendo tanto la anatomía como la fisiología de esta estructura su forma no se asemeja a la de una almendra y su denominación actual no está acorde con los requerimientos de la FIPAT por lo cual consideramos que esta debe ser revisada.

SUMMARY: In medical terminology the term brain amygdala is used to refer to the structure that according to the Terminologia Neuroanatomica and Terminologia Anatomica is known as the amydaloid body, which is made up of various nuclei and is responsible for emotions, behavior, regulation of the anxiety, aggression, fear, emotional memory, social cognition, and responses to stress. Being the cerebral amygdala such an important structure, the objective of this study was: to analyze the meaning of the term cerebral amygdala in Terminologia Neuroanatomica and in Terminologia Anatomica and to contrast if the origin of its Greek Latin roots agrees with the function of this structure according to the requirements of the FIPAT. For this, the dictionaries of the Royal Spanish Academy, the DGE Greek Spanish Dictionary, the VOX Greek Spanish Dictionary, the Medical, Biological, Histological and Etymological Dictionary of the University of Salamanca, the Dictionary of the Royal National Academy of Medicine, as well as some articles and classic books of anatomy. The results indicated that the term amygdala has the same meaning in Greek as in Latin, where? ἀμυγδαλέα, ἀμυγδαλέας (pr. Amygdaléa, amygdaléas) is the almond tree andἀμυγδάλη, ἀμυγδάλης (pr. amygdále, amygdáles) means almond. Knowing both the anatomy and the physiology of this structure, its shape does not resemble that of an almond and its current name is not in accordance with the requirements of the FIPAT, for which we consider that it should be revised.

T2 Relaxation Times of the Cingulate Cortex, Amygdaloid Body, Hippocampal Body, and Insular Cortex: Comparison of 1.5 T and 3.0 T

PURPOSE: To compare T2 relaxation times (T2) in the cingulate cortex, amygdaloid body, hippocampal body, and insular cortex between 1.5T and 3.0T MR imagers. MATERIALS AND METHODS: Twelve healthy volunteers underwent FLAIR and CPMG imaging perpendicular to the hippocampal body at both 3.0T and 1.5T. T2 was measured in the cingulate cortex, amygdaloid body, hippocampal body, and insular cortex. The T2 relaxation time ratios of the cingulate cortex, insular cortex, and amygdaloid body to the hippocampal body were compared between 1.5T and 3.0T. RESULTS: The mean T2 of the cingulate cortex, amygdaloid body, hippocampal body, and insular cortex at 1.5T were 109.5+/-3.1, 117.0+/-7.1, 114.7+/-2.4, and 111.3+/-2.4, respectively; 99.7+/-3.8, 100.7+/-4.3, 97.9+/-3.4, and 96.2+/-2.0, respectively, at 3.0T. Percentage changes of T2 in the cingulate cortex, insular cortex, amygdaloid body, and hippocampal body at 3.0T with respect to those at 1.5T were -8.9%, -13.5%, -14.6%, and -13.5%, respectively. The mean T2 ratios of the cingulate gyrus, insular cortex, and amygdaloid body to the hippocampal body at 1.5T and 3.0T were 0.96 and 1.02 (p=0.003); 1.02 and 1.03 (p>0.05); 0.97 and 0.98 (p>0.05), respectively. CONCLUSION: T2 decrease in the cingulate cortex was less than the amygdaloid body, insular cortex, and hippocampal body at 3.0T. The mean T2 ratio of the cingulate gyrus to the hippocampal body was significantly different between 1.5T and 3.0T.

Effects of enfluane and isoflurane on the spontaneous neural discharge of central amygdaloid nucleus in rats / 中华麻醉学杂志

Objective To determine the effects of enflurane and isoflurane on the spontaneous neural discharge of central amygdaloid nucleus in rats Methods SD rats (30 60 d) of either sex were decapitated Brain was immediately removed and kept in 4℃ artificial cerebral spinal fluid(ACSF) which was balanced with 95% O 2 and 5% CO 2 gas mixture Braine tissue containing central amyfdaloid nucleus was cut into slices of 300 400?m thick which were immersed in ACSF Enflurane and isoflurane were administered by balancing ACSF with enflurane (1 5%,3 0%,4 5%) or isoflurane (1 1%,2 2%,3 3%) The spontaneous neural discharge of central amygdaloid nucleus was measured before and after enflurane or isoflurane using whole cell patch clamp techniques Results Enflurane and isoflurane inhibited the frequencies of spontaneous neural discharge of central amygdaloid nucleus in a dose dependent manner The spontaneous neural discharge inhibited by enflurane (3 0%) and isoflurane (2 2%) could recover after the slices being washed with normal ACSF for 5 min Conclusions The results indicate that the spontaneous neural discharge of central amygdaloid nucleus can be inhibited reversibly by enflurane and isoflurane Central amygdaloid nucleus may by one of the sites of action of enflurane and isoflurane in central nervous system
