What is the Alveus?
The alveus is white matter consisting of myelinated afferents and efferents. As the fibers of the alveus travel posteriorly, they aggregate medially to form the fimbria of the fornix. Fimbria means fringe and in this case it is the fringe of the hippocampus.
What is the amygdala function?
The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
What are the functions of the limbic system?
The limbic system is the part of the brain involved in our behavioural and emotional responses, especially when it comes to behaviours we need for survival: feeding, reproduction and caring for our young, and fight or flight responses.
What information does the fornix carry?
Function. Being the main output tract of the hippocampus, the primary role of the fornix is to transmit the information from the hippocampus to the mammillary bodies and to the anterior nuclei of thalamus.
What is the purpose of Archicortex?
Archicortex is a type of cortical tissue that consists of three laminae (layers of neuronal cell bodies). Archicortex is most prevalent in the olfactory cortex and the hippocampus, which are responsible for processing smells and forming memories, respectively.
How does the hippocampus work?
The hippocampus helps humans process and retrieve two kinds of memory, declarative memories and spatial relationships. Declarative memories are those related to facts and events. The hippocampus is also where short-term memories are turned into long-term memories. These are then stored elsewhere in the brain.
What is the function of the amygdala and hippocampus?
The amygdala is specialized for input and processing of emotion, while the hippocampus is essential for declarative or episodic memory. During emotional reactions, these two brain regions interact to translate the emotion into particular outcomes.
Why is the amygdala so important?
The amygdala is especially important in the development of fear, and reflexive fear reactions are due in part of the functioning of the amygdala. The amygdala also enables the brain to transform short-term memories into long-term memories, a process called memory consolidation.
What does the amygdala regulate?
The amygdalae, a pair of small almond-shaped regions deep in the brain, help regulate emotion and encode memories—especially when it comes to more emotional remembrances.
What are the 3 main functions of the limbic system?
The limbic system functions to facilitate memory storage and retrieval, establish emotional states, and link the conscious, intellectual functions of the cerebral cortex with the unconscious, autonomic functions of the brain stem.
What does alveolus stand for in medical dictionary?
[al-ve´o-lus] (pl. alve´oli) (L.) a little hollow, as the socket of a tooth, a follicle of an acinous gland, or a pulmonary alveolus. adj., adj alve´olar.
Where was the alveus in the caldarium?
At one end of the caldarium we find the bath basin, alveus; at the other is the support of the labrum, which has disappeared. This alveus would accommodate eight bathers, that in the men’s caldarium perhaps ten. The square basin ( alveus or baptisterium) which served for the warm baths was of marble.
How big is the sphere of an alveolus?
Individual alveolus was approximated using a 0.3 mm diameter sphere. A rare case of lateral proboscis with clefts of the lip, alveolus, and primary and secondary palates treated by surgical excision and repair of the cleft lip is presented.
How does the alveolus help a cleft lip?
Offering a pleasing esthetic appearance in a patient with cleft lip and alveolus is one of the toughest job in dental practice. They absorb freshly inhaled oxygen into the bloodstream via tiny capillaries near the wall of the alveolus and release the cellular respiration waste product, carbon dioxide, into the atmosphere during exhalation.
