What is the bundle of nerve fibers that sends information from one half of the brain to the other half?
What is the bundle of nerve fibers that sends information from one half of the brain to the other half?
The corpus callosum connects the two halves of the brain and delivers messages from one half of the brain to the other. The surface of the cerebrum contains billions of neurons and glia that together form the cerebral cortex.
What is a bundle of nerves that go to and from the brain?
The spinal cord is a long bundle of nerve tissue about 18 inches long and 1/2-inch thick. It extends from the lower part of the brain down through spine. Along the way, nerves branch out to the entire body.
What is the big bundle of nerve fibers connecting the eye to the brain called?
Corpus callosum, bundle of nerve fibres in the longitudinal fissure of the brain that enables corresponding regions of the left and right cerebral hemispheres to communicate. The axons and dendrites of the neurons in the corpus callosum synapse with cortical neurons on symmetrically related points of the hemispheres.
What part of the brain controls sensations?
Cerebrum
Cerebrum. The cerebrum is the part of the brain that receives and processes conscious sensation, generates thought, and controls conscious activity.
Which is the best definition of a bundle of nerves?
1. Any of the cordlike bundles of fibers made up of neurons through which sensory stimuli and motor impulses pass between the brain or other parts of the central nervous system and the eyes, glands, muscles, and other parts of the body. Nerves form a network of pathways for conducting information throughout the body. 2.
Where are the nerve fibers located in the brain?
After the chiasm, the nerve fibers extend to the lateral geniculate nucleus (LGN) in the thalamus. From there, the nerve fiber tracts extend from the LGN into optic radiation fibers that fan through different parts of the brain including the parietal lobe, temporal lobe, and occipital lobe.
What makes up the nervous system of the human body?
Your nervous system is composed of a network of nerves and nerve cells that carry messages to and from the brain and spinal cord and the rest of the body. A nerve is a bundle of fibers that receives and sends messages between the body and the brain.
Where does the optic nerve enter the brain?
The optic nerve is a bundle of fibers that transmits visual information between the retina and the brain. The area where the optic nerve enters the back of the eyeball is known as the optic disc. The brain and optic nerve are surrounded by cerebrospinal fluid (CSF), which helps to keep them stable and protected from damage from sudden movements.
