What does lateral funiculus mean?
What does lateral funiculus mean?
The lateral funiculus is the area of white matter located between the posterolateral and anterolateral sulci.
What is funiculus in spinal cord?
Pathways. Spinal Cord White Matter. In each half of the spinal cord, white matter is divided into three major bundles, called funiculi. The dorsolateral sulcus marks the division between dorsal funiculus and lateral funiculus.
Is funiculus the same as column?
A pathway is a group of tracts with a related function (e.g. postsynaptic dorsal column pathway). The horns of gray matter divide the white matter into three columns (funiculi): dorsal, lateral and ventral.
Where is the funiculus?
the spinal cord
Latin for “string,” funiculus refers to a bundle of nerve fibers and is specifically used to refer to one of the three subdivisions of white matter in the spinal cord: the anterior, posterior, and lateral funiculi.
What is the role of funiculus?
The funiculus provides the sole channel of communication between the seed and the parent plant; however, little is known about its role in nutrient supply during seed maturation.
Where is lateral horn of spinal cord?
The lateral horn of the spinal cord is the small lateral projection of grey matter located between the dorsal horn and ventral horn and contain the neuronal cell bodies of the sympathetic nervous system.
What is the function of funiculus?
What is another name for funiculus?
n. spinal cord, Medulla Spinalis, spermatic cord, umbilical cord, umbilical.
What does the lateral funiculus contain?
The lateral funiculus contains both ascending and descending nerve fiber tracts. The anterior funiculus lies between the emergence of the anterior root fibers and the anterior median fissure. The anterior funiculus also contains both ascending and descending nerve fiber tracts.
What is difference between funiculus and fasciculus?
A funiculus is a small bundle of axons (nerve fibres), enclosed by the perineurium. A small nerve may consist of a single funiculus, but a larger nerve will have several funiculi collected together into larger bundles known as fascicles. Fascicles are bound together in a common membrane, the epineurium.
How is funiculus related to a nerve trunk?
Scientific definitions for funiculus In some plants, the funiculus develops into a fleshy seed covering called an aril. A slender, cordlike strand or band, especially a bundle of nerve fibers in a nerve trunk. Any of three major divisions of white matter in the spinal cord.
What is a fasciculus vs funiculus?
As nouns the difference between fasciculus and funiculus is that fasciculus is (anatomy) a small bundle of nerve, muscle or tendon fibers while funiculus is (anatomy) any of several cordlike structures, especially the umbilical cord, or a bundle of nerve fibres in the spinal cord.
