What else can I help you with?
What happens when you have 2 cerebral cortex?
You actually have two as the brain is divided into two hemispheres each covered by a cortex and connected by nerve fibers in the corpus callosum.
Fibers that connect the cerebral cortex and the cerebellum would be called projection fibers?
Projection fibers are long nerve fibers that connect the cerebral cortex to lower regions of the brain, such as the cerebellum. They are responsible for transmitting information between these two brain regions.
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 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.
What is the internal capsule?
The internal capsule is the major structure carrying ascending and descending nerve projection fibers to and from the cerebral cortex
How striatum is related to fibers of internal capsule?
The striatum is a structure in the brain that is closely connected to the fibers of the internal capsule. The internal capsule contains important motor and sensory pathways that carry information to and from the cerebral cortex and the brainstem. Fibers from the cortex travel through the internal capsule to reach the striatum, forming a crucial pathway for communication between different regions of the brain involved in movement and control.
What is the white matter that lies beneath the cerebral cortex?
The white matter beneath the cerebral cortex is made up of myelinated nerve fibers that connect different regions of the brain. These fibers facilitate communication between different areas of the brain by transmitting electrical signals.
What is cerebral peduncle?
The cerebral peduncles are found in the midbrain and are responsible for connecting the cerebral cortex to the spinal cord. They carry important motor and sensory information between these two regions. Damage to the cerebral peduncles can result in various neurological deficits.
Which neural fibres connect cerebral cortex to third ventricle in brain?
The neural fibers that connect the cerebral cortex to the third ventricle are primarily the fibers of the cingulum. The cingulum is a bundle of myelinated axons that runs along the inner surface of the cingulate gyrus and connects various parts of the limbic system, including the cortex to the septal area and the hippocampus, which is adjacent to the third ventricle. Additionally, the anterior commissure also plays a role in connecting the two hemispheres and linking cortical areas to the third ventricle region.
What type of white matter fibers connects and allows communications between the cerebral hemispheres and the body?
The type of white matter fibers that connect and allow communication between the cerebral hemispheres and the body are known as projection fibers. These fibers extend from the cerebral cortex to lower brain regions and the spinal cord, facilitating the transmission of motor and sensory information. An example of such fibers is the corticospinal tract, which conveys motor signals from the brain to the spinal cord. Additionally, other projection fibers connect to subcortical structures, enabling complex interactions between different parts of the nervous system.
What is the differences between commissures association fibers and projection fibers?
Association fibers connect different portions of cerebral hemisphere allowing cerebral cortex to function as a integrated whole whereas projection fibers connect cerebral hemispheres to other portions of brain n spinal cord
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.
