What else can I help you with?
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 are the areas within the cerebrum named for the bones that lie beneath?
The areas within the cerebrum named for the bones that lie beneath are the frontal, parietal, temporal, and occipital lobes. These lobes are named based on the skull bones that they are situated above.
What are the three main regions of the brain?
I'm not an expert, but the major lobes are the Frontal lobe, Parietal lobe, Occipital lobe, and the Temporal Lobes. Other important areas would be the Cerebellum, Wernicke's Area, Broca's Area, Thalamus, Amygdala, Hypothalamus, Hippocampus, the Sensory cortex and the Motor cortex. I think those are the main parts of the brain. There are obviously a lot more areas, but those are the most known areas from what I've read.
What are the three major areas of the brian?
The three major areas of the brain are the cerebrum, responsible for higher brain functions such as thinking and voluntary movement; the cerebellum, responsible for coordination and balance; and the brainstem, which controls basic life functions such as breathing and heart rate.
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 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
Where in the brain is the hypothalamus?
The hypothalamus is a small part of the brain located just below the thalamus on both sides of the third ventricle. (The ventricles are areas within the cerebrum that are filled with cerebrospinal fluid, and connect to the fluid in the spine.) It sits just inside the two tracts of the optic nerve, and just above (and intimately connected with) the pituitary gland.
What are commisural tracts in the brain?
Commissural tracts are bundles of nerve fibers that connect corresponding areas of the two cerebral hemispheres. The largest and most prominent commissural tract is the corpus callosum, which enables communication and coordination between the two hemispheres of the brain.
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 Part of the brain that controls sensory receptors and interprets language?
Your memory is controlled by the cerebrum. and the frontal and temporal lobes are the main areas of speech and language.
What functional areas of the cerebrum is responsible for conscious movements the body?
Primary motor area.
What are the functional differences between the cerebellum and cerebrum?
The differences between cerebrum and cerebellum are: Cerebrum has sensory areas that interpret sensory activities, association areas that are concerned with emotional and intellectual processes like will, judgement, memory etc. It controls all voluntary activities. Cerebellum coordinates muscular activities and maintains body posture and balance.
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 the areas within the cerebrum named for the bones that lie beneath?
The areas within the cerebrum named for the bones that lie beneath are the frontal, parietal, temporal, and occipital lobes. These lobes are named based on the skull bones that they are situated above.
Which fiber tract carries impulses from the cerebrum to lower CNS areas?
The corticospinal tract carries impulses from the cerebrum to lower CNS areas, primarily to control voluntary movements throughout the body. It is involved in motor function and helps in coordinating muscle movements.
What lobe of cerebrum contains the primary visual areas that interpret what a person sees?
The occipital lobe contains the primary visual areas that interpret what a person sees.
Is the cerebrum the motor command center?
The cerebrum is not the motor command center, but it is involved in controlling voluntary movements. The primary motor cortex in the cerebrum is responsible for sending signals to the muscles to initiate movement. Other areas of the brain, such as the cerebellum and basal ganglia, also play important roles in coordinating and refining motor commands.
