The mammillary bodies are a pair of small round bodies, located on the undersurface of the brain that, as part of the diencephalon, form part of the limbic system. They are located at the ends of the anterior arches of the fornix. [2] They consist of two groups of nuclei, the medial mammillary nuclei and the lateral mammillary nuclei.
The mammillothalamic tract (also mammillary fasciculus, [1] mammillothalamic fasciculus, thalamomammillary fasciculus, bundle of Vicq d'Azyr) is an efferent pathway of the mammillary body which projects to the anterior nuclei of the thalamus. It consists of heavily myelinated fibres. [1] It is part of a brain circuit involved in spatial memory ...
The fornix (from Latin: fornix, lit. 'arch'; pl.: fornices) is a C-shaped bundle of nerve fibers in the brain that acts as the major output tract of the hippocampus. The fornix also carries some afferent fibers to the hippocampus from structures in the diencephalon and basal forebrain. The fornix is part of the limbic system.
The mammillary bodies are two clusters of cell bodies found at the ends of the posterior fibres of the fornix within the diencephalon. The mammillary bodies relay information from the hippocampal formation (via the fornix) to the thalamus (via the mammillothalamic tract). The mammillary bodies are integral parts of the limbic system and have ...
The Papez circuit involves various structures of the brain. It begins and ends with the hippocampus (or the hippocampal formation). Fiber dissection indicates that the average size of the circuit is 350 millimeters. The Papez circuit goes through the following neural pathways: Hippocampal formation (subiculum) → fornix → mammillary bodies ...
The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain. [1] Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction.
62209. Anatomical terms of neuroanatomy. [edit on Wikidata] In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus ...
The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...
