The anterior and posterior grey columns present as projections of grey matter and are also known as the horns of the spinal cord. The white matter is located outside of the grey matter and consists almost totally of myelinated motor and sensory axons. Columns of white matter known as funiculi carry information either up or down the spinal cord.
Dorsal column–medial lemniscus pathway. The formation of the spinal nerve from the dorsal and ventral roots. Originating in peripheral sensory receptors, the dorsal column-medial lemniscus pathway transmits fine touch and conscious proprioceptive information to the brain. The dorsal column–medial lemniscus pathway (DCML) (also known as the ...
White matter forms the bulk of the deep parts of the brain and the superficial parts of the spinal cord. Aggregates of grey matter such as the basal ganglia ( caudate nucleus , putamen , globus pallidus , substantia nigra , subthalamic nucleus , nucleus accumbens ) and brainstem nuclei ( red nucleus , cranial nerve nuclei) are spread within the ...
Pia mater is the thin, translucent, mesh-like meningeal envelope, spanning nearly the entire surface of the brain. It is absent only at the natural openings between the ventricles, the median aperture, and the lateral aperture. The pia firmly adheres to the surface of the brain and loosely connects to the arachnoid layer. [ 6 ]
Corticospinal tract. The corticospinal tract is a white matter motor pathway starting at the cerebral cortex that terminates on lower motor neurons and interneurons in the spinal cord, controlling movements of the limbs and trunk. [1] There are more than one million neurons in the corticospinal tract, and they become myelinated usually in the ...
75254. Anatomical terms of neuroanatomy. [edit on Wikidata] In neuroanatomy, the medullary pyramids are paired white matter structures of the brainstem 's medulla oblongata that contain motor fibers of the corticospinal and corticobulbar tracts – known together as the pyramidal tracts. The lower limit of the pyramids is marked when the fibers ...
The grey columns are three regions of the somewhat ridge-shaped mass of grey matter in the spinal cord. [1] These regions present as three columns: the anterior grey column, the posterior grey column, and the lateral grey column, all of which are visible in cross-section of the spinal cord. The anterior grey column is made up of alpha motor ...
The lateral spinothalamic tract (or lateral spinothalamic fasciculus), is a bundle of afferent nerve fibers ascending through the white matter of the spinal cord, in the spinothalamic tract, carrying sensory information to the brain. It carries pain, and temperature sensory information (protopathic sensation) to the thalamus.
