Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the trigone of the lateral ventricle.
anterior horn of lateral ventricle in the brain, which passes forward, laterally, and slightly downward from the interventricular foramen into the frontal lobe anterior horn of spinal cord , the ventral (front) grey matter section of the spinal cord which contains motor neurons that affect the skeletal muscles
The location of motor neurons in the anterior grey column of the spinal cord. The anterior grey column, (also known as the anterior horn of spinal cord and anterior cornu) is broad and of a rounded or quadrangular shape. Its posterior part is termed the base, and its anterior part the head, but these are not differentiated from each other by ...

The head and body of the caudate nucleus form part of the floor of the anterior horn of the lateral ventricle. The body travels briefly towards the back of the head; the tail then curves back toward the anterior, forming the roof of the inferior horn of the lateral ventricle. This means that a coronal section (on a plane parallel to the face ...
The anterior grey column, also known as the anterior horn of spinal cord, comprises three different types of neurons: large alpha motor neurons, medium gamma motor neurons, and small neurons thought to be interneurons. These neurons differ in both their morphology and in their patterns of connectivity.
The anterior corticospinal tract is usually small, varying inversely in size with the lateral corticospinal tract, which is the main part of the corticospinal tract. It lies close to the anterior median fissure , and is present only in the upper part of the spinal cord; gradually diminishing in size as it descends, it ends about the middle of ...
Medial vestibulospinal fibers join with the ipsilateral and contralateral medial longitudinal fasciculus, and descend in the anterior funiculus of the spinal cord. [2] [7] Fibers run down to the anterior funiculus to the cervical spinal cord segments and terminate on neurons of laminae VII and VIII. Unlike the lateral vestibulospinal tract, the ...
