STRIA MEDULLARIS Meaning and
Definition
-
The term "stria medullaris" refers to a specific anatomical structure found in the brain. It refers to a thin band or stripe of white matter that is located within the ventricular system, specifically in the lateral ventricles of the brain. The stria medullaris runs from the fornix, a bundle of nerve fibers, towards the septal nuclei.
The stria medullaris plays a crucial role in the brain's limbic system, which is responsible for regulating emotions, memory, and motivation. It is a part of the Papez circuit, a neural pathway that connects various brain regions involved in the processing of emotions and memory consolidation.
Functionally, the stria medullaris is involved in the communication between the fornix and the septal nuclei, allowing for the exchange of information between these two structures. This communication is important for the regulation of emotional responses and memory formation.
The stria medullaris is composed mainly of myelinated axons, which are the conducting fibers of neurons. The myelin sheath surrounding these axons gives the stria its white appearance. It is important to note that the stria medullaris can be visualized using imaging techniques such as MRI, which allows for the study and evaluation of potential abnormalities or pathologies in this brain region.

Medullary s., (1) s. fornicis, s. pinealis, a longitudinal strand of fibers along the wall of the third ventricle just below the taenia thalami; many of the fibers end in the nucleus, or ganglion, habenulae, others cross to the opposite side on the dorsum of the habenula forming there the commissura habenularum; (2) acoustic s., auditory s., one of the horizontal white stripes on the floor of the fourth ventricle passing from the mesial groove outward over the upper part of the restiform body; they divide the rhomboidal fossa into the fovea inferior and fovea superior on either side.
