nerve tract

The formation of a nerve tract follows several basic rules.

There are numerous nerve tracts located within this section of the brainstem.

This area contains many nerve tracts conveying motor information to and from the brain to the rest of the body.

Neurotoxins can be used to selectively damage very specific nerve tracts in the brain.

The fornix is a bundle of nerve tracts made of white matter.

But when muscles are stimulated with electrodes and exercise, the nerve tracts sometimes partly revive.

Ascending nerve tracts control sensory functions, while descending control motor.

This surgery can prove challenging in the head and neck region due to this tumour's tendency spread along nerve tracts.

Composed of Schwann cells, these masses are generally slow growing and can be found in the peripheral nerve tract, often around the head and neck.

The absence of such nerve tracts suggests that L1 is involved in the growth of axons within the embryonic nervous system."

Four of these ganglia are arranged in a ring round the gut, interconnecting with a big abdominal ganglion by large nerve tracts.

Many spinal cord injuries leave some ascending and descending nerve tracts alive but stunned, Dr. McDonald said.

Studies of invertebrate and vertebrate nervous systems demonstrated that the initial nerve tracts are formed by the axons of so-called pioneer neurons.

They get their name from their roughly hemispherical calyx, a protuberance that is joining to the rest of the brain by a central nerve tract or peduncle.

Neurons are concentrated in clusters with short interconnecting axons and dendrites between the cells of the group and defined nerve tracts leading in and out.

Sensory nerve tracts and motor nerve tracts are located in adjacent lanes on the neurological highway of the spinal cord.

Evolutionary innovations such as nerve tracts, seriation, mesoderm, spacious body cavities and circulatory systems, all implied by the fossils already available, must have had profound phylogenetic consequences.

The neurons in the optic nerve decussate in the optic chiasm with some crossing to the contralateral optic nerve tract.

The white ramus communicans (plural: rami communicantes, ramus means branch) is the preganglionic sympathetic outflow nerve tract from the spinal cord.

Some of the coarser ones have long been known from simple histological studies, but more recent mapping of the nerve tracts and individual axonal connections has required a variety of specialized techniques.

The endocrine system is the system of glands, each of which secretes different types of hormones directly into the bloodstream (some of which are transported along nerve tracts) to maintain homeostasis.

In special cases, where only one eye deviates and the other does not, this often indicates a lesion (or damage) of the medial longitudinal fasciculus (MLF) which is a brainstem nerve tract.

Further studies may address the question that inevitably arises in this field: did the experiment truly destroy the nerve tract being studied, or might the damage have been incomplete and the animals' recovery due to normal healing rather than regeneration?

When the researchers did anatomical studies, injecting dyes into the nerve tracts after the rats had been killed, they found that nerves had regrown from either end of the injury, growing down to the tail and up to the brain.

More specifically, the damage was in a part of the nerve tract called the arcuate fasciculus, which the mechanism of action is unknown but it is shown to connect the posterior (back) of the brain to the anterior (front) and vice versa.
