This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
This traditional list does not accord strictly with human thalamic anatomy. Nuclear groups of the thalamus include: anterior nuclear group [1] (anteroventral, [2] anterodorsal, [3] anteromedial [4]) medial nuclear group (medial dorsal nucleus, [5] a.k.a. dorsomedial) parvocellular part [6] (a.k.a. parvicellular part) magnocellular part [7]
Many of the thalamic nuclei receive inputs from the hippocampal formation. The mammillothalamic tract relays information received from the mamillary bodies (via the fornix) and transmits it to the anterior nuclei of the thalamus. Research has shown that the thalamus plays a key role with respect to spatial and episodic memories. [6]
The midline nuclear group (or midline thalamic nuclei) is a region of the thalamus consisting of the following nuclei: paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus; paratenial nucleus (nucleus parataenialis) nucleus reuniens (also known as the ...
The thalamic fasciculus is formed by the fibers of the ansa lenticularis and the lenticular fasciculus that merge in the field H of Forel. The fibers of this fasciculus then travel to the thalamus and primarily terminate in the ventral anterior nucleus and ventral lateral nucleus. [2] Some fibers travel to the interthalamic nuclei.
Sensory pathways from the periphery to the cortex are separate for touch-position and pain-temperature sensations. All sensory information is sent to specific nuclei in the thalamus. Thalamic nuclei, in turn, send information to specific areas in the cerebral cortex. Each pathway consists of three bundles of nerve fibers connected in series:
The first-order neurons from the trigeminal ganglion enter the pons and synapse in the principal (chief sensory) nucleus or spinal trigeminal nucleus.Axons of the second-order neurons cross the midline and terminate in the ventral posteromedial nucleus of the contralateral thalamus (as opposed to the ventral posterolateral nucleus, as in the dorsal column medial lemniscus (DCML) system).
Nuclei of the Thalamus Both the left and right hemispheres of the brain have a lateral geniculate nucleus, named after its resemblance to a bent knee ( genu is Latin for "knee"). In humans as well as in many other primates , the LGN has layers of magnocellular cells and parvocellular cells that are interleaved with layers of koniocellular cells.
