#limbic system

• Amygdala — An ovoid anatomical formation consisting of lymphoid tissue or nerve nuclei. In general anatomy, it most frequently refers to the palatine tonsils, located in the oropharynx, serving as a protective immune barrier. In neuroanatomy, the amygdala (amygdaloid body) represents a key structure of the cerebral limbic system, located in the temporal lobe, essential for processing emotions, such as fear, and for storing emotional memories.
• Tonsillar — Pertaining to or relating to the tonsils (palatine tonsils) or the cerebral amygdaloid complex; located in the area of the tonsils or correlated with their immune or emotional function. In general medical practice, it describes structural elements like pits, arteries, or infections in the throat, while in neurosciences it refers to nerve circuits involved in fear and anxiety responses.
• Amygdaloid — Resembling an almond in shape; ovoid and slightly flattened. In neuroanatomy, it describes the amigdaloid body (or cerebral amygdala), a deep nuclear structure essential for emotional processing. In mineralogy, it refers to the texture of a volcanic rock whose vesicles have been subsequently filled with secondary minerals, forming oval nodules.
