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
Which type of white matter fiber tract connects the cerebrum to lower centers like the spinal cord?
Projection Fibers
How many types of association fibers that can be found in the white matter of cerebrum?
2 types = short + long association fibres
Does Projection fibers in the brain mainly connect the right and left hemispheres?
No, They connect the white matter of the cerebrum with parts outside of it
Which white matter tracts connect the cerebrum to the lower brain areas?
The internal capsule and the cerebral peduncles are white matter tracts that connect the cerebrum to lower brain areas such as the brainstem. These pathways are important for transmitting signals between different regions of the brain.
Where is white matter?
It is located in the brain,in the cerebrum
Pertaining to the outer section of the cerebrum?
The outer section of the cerebrum is known as the cerebral cortex. It is the grey matter of the brain.
A fold of cortical gray matter on the surface of the cerebrum?
gyri
How can the functional anatomy of the spinal cord be described using the terms white and gray matter roots spinal nerves and tracts?
White matter is one of the two components of the central nervous system, and it consists mostly of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers. Grey matter contains neural cell bodies, unlike white matter, it does not and it mostly contains myelinated axon tracts. Tracts are bundles of fibers that connect to different parts of the central nervous system. A collection of related anatomic structures Roots receive information sent by neurons. Spinal nerves refer to a mixed of spinal nerves, which carry motor, sensory, and autonomic signals between the spinal cord and the body.
What is the inner core of the brain composed of?
The inner core of the brain is primarily composed of nerve fibers and neural connections. It consists of structures such as the thalamus, hypothalamus, and pineal gland that play vital roles in regulating functions such as sensory perception, hormone production, and circadian rhythms.
The islands of gray matter inside the hemisphere of the cerebrum are known as the cerebral cortex?
The few islands of gray matter within the interior of the cerebrum are made up of neuron cell bodies and unmyelinated axons. These areas of gray matter act as the central processing unit of the brain. Many things can affect this gray matter, such as, smoking, child abuse, alcoholism, and drugs.
What does the cerebral cortex cover?
The cerebral cortex is the outer layer of the cerebrum, or large brain. It also is where most of the grey matter, i.e. neuronal cell bodies, are found. So you could say that the cerebral cortex covers the white matter of the cerebrum.
