What else can I help you with?
What is internal capsule and why it is given that name?
It is a broad lamina of white matter made up of projection fibres which pass to and from the cerebral cortex.It's called as "internal capsule" simply because it forms an internal (inner) capsule to the lentiform nucleus.
What are long association fibers that can be found in the white matter of cerebrum?
They are four bundles of long fibres which connect the different lobes of the cerebral hemisphere together.These 4 bundles are = superior longitudinal + inferior longitudinal + cingulum + uncinate bundles
What is the origin of medial corticobulbar fibers?
The medial corticobulbar fibers originate from the primary motor cortex (M1) in the precentral gyrus of the brain. These fibers are part of the corticobulbar tract, which is responsible for carrying motor signals from the cerebral cortex to the brainstem nuclei that control the muscles of the face, head, and neck.
What are the ascending fibres of projection fibres?
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
What are the best descriptions for short association fibers that can be found in the white matter of cerebrum?
consist of "arcuate fibres" (U-shape bands)connect adjacent gyri with one anotherpresent in all parts of the hemisphere
What is the difference between the two types of projection fibers?
Ascending fibres = from thalamus to cerebral cortexDescending fibres = from cerebral cortex to lower centres
What are the three types of fibers that can be found in the white matter of cerebrum?
association fibres = connect the different cortical areas in the same hemispherecommisural fibres = connect one part of the CNS on one side with the same part on the opposite sideprojection fibres = connect the cerebral cortex with lower centres
What is the fiber tract that provides for communication between different parts of the same cerebral hemisphere called?
Association fibres. They are also known as fasciculi. (Projection fibres connect brain and spinal cord, Commisural fibres connect opposite hemispheres)

Is ligament a connective tissue?
ligaments are tough elastic fibres which connect bone to bone.
What are the descending fibres of projection fibres?
They include = cortico-spinal fibres + cortico-bulbar fibres + cortico-pontine fibres + cortico-rubral fibres + cortico-striate fibres
What are the best descriptions for short association fibers that can be found in the white matter of cerebrum?
consist of "arcuate fibres" (U-shape bands)connect adjacent gyri with one anotherpresent in all parts of the hemisphere
What are some protein fibres in the cellular matrix?
Collagen fibres, reticular fibres, and elastic fibres and protein fibres found in the cellular matrix.
What are blended fibres?
Blended fibres is mixing 2 or more fibres to achieve the best fibres in the yarn.
