They include = cortico-spinal fibres + cortico-bulbar fibres + cortico-pontine fibres + cortico-rubral fibres + cortico-striate fibres
Ascending fibres = from thalamus to cerebral cortexDescending fibres = from cerebral cortex to lower centres
Association fibres. They are also known as fasciculi. (Projection fibres connect brain and spinal cord, Commisural fibres connect opposite hemispheres)
Projection Fibres
The internal capsule is the major structure carrying ascending and descending nerve projection fibers to and from the cerebral cortex

They are fibres which radiate from thalamus and metathalamus to the cerebral cortex. They include:Anterior thalamic radiationsuperior thalamic (sensory) radiationposterior thalamic radiation, which consists of = optic + auditory radiations
Collagen fibres, reticular fibres, and elastic fibres and protein fibres found in the cellular matrix.
Blended fibres is mixing 2 or more fibres to achieve the best fibres in the yarn.
ascending (sensory/afferent) and descending (efferent/motor) tracts.Addition: Other than these two types of tracts, the white matter of spinal cord also contains "associative tracts" containing short ascending and descending fibres which coordinate the function of the different regions of spinal cord.
Cotton is all cotton fibres.
Cotton fibres are the fibres in cotton.
