Axons that cross from one side of the brain to the other are called commissural fibers. These fibers connect the corresponding areas of the brain's two hemispheres, allowing them to communicate and coordinate information processing. An example of a commissural fiber bundle is the corpus callosum.

What are axons that conduct impulses from the cerebrum to lower parts of the CNS?
Axons that conduct impulses from the cerebrum to lower parts of the central nervous system (CNS) are called descending axons. These axons transmit motor commands and information from the brain down to the spinal cord and other lower regions of the CNS. They play a crucial role in controlling voluntary movement and coordinating various bodily functions.
The branchlike structures the receive messages from other neurons are called?
Axons
Do axons receive impulses toward the body cells?
No, axons transmit impulses away from the body cells. Dendrites receive impulses from other neurons and transmit them to the cell body, and then the axon carries the impulse away from the cell body to other neurons or to muscles or glands.
When your hit in the head do you damage the neurons in your brain or the axons?
When you are hit in the head, both neurons and axons can sustain damage. Neurons are the specialized cells responsible for transmitting electrical signals in the brain, while axons are long, slender projections that extend from neurons and transmit those signals to other neurons or tissues. Impact to the head can cause direct damage to neurons and axons, leading to functional impairment or cell death.
Who was dendrite's partner?
The partner of dendrite in the brain is the axon. Dendrites receive signals from other neurons and transmit them to the cell body, while axons transmit signals away from the cell body to other neurons. Together, dendrites and axons play a crucial role in communication within the nervous system.
What are Bundles of axons are called?
Bundles of axons are called nerves. Nerves transmit electrical signals between the brain and other parts of the body.
Where do axons from the olfactory nerve project to?
Axons from the olfactory nerve project to the olfactory bulb in the brain. The olfactory bulb processes and relays information about smells to other areas of the brain, such as the olfactory cortex, where scent perception occurs.
How do olfactory receptors send axons through the cribriform plate?
Olfactory receptor neurons extend axons through tiny channels in the cribriform plate called olfactory foramina. These axons then travel through the olfactory nerve to the olfactory bulb in the brain, where they synapse with other neurons to transmit smell signals. The olfactory foramina allow for the passage of these axons while protecting the brain from potential pathogens or irritants in the nasal cavity.
What are profuse branches at the end of axons called?
The profuse branches at the end of axons are called axon terminals or synaptic terminals. These structures contain neurotransmitters that are released to communicate with other neurons or target cells at synapses.
What are axons that conduct impulses from the cerebrum to lower parts of the CNS?
Axons that conduct impulses from the cerebrum to lower parts of the central nervous system (CNS) are called descending axons. These axons transmit motor commands and information from the brain down to the spinal cord and other lower regions of the CNS. They play a crucial role in controlling voluntary movement and coordinating various bodily functions.
The branchlike structures the receive messages from other neurons are called?
Axons
Neurons are composed of a network of fine threads called?
Neurons are composed of a network of fine threads called dendrites, which receive signals from other neurons, and axons, which transmit signals to other neurons. These structures form the basic communication network within the brain and nervous system.
What is a cable-like bundle of fibers or axons?
A cable-like bundle of fibers or axons is called a nerve. Nerves carry electrical impulses between the brain, spinal cord, and other parts of the body to coordinate various functions such as movement, sensation, and organ control.
What is a long nerve fiber that convey electrical impulses to other cells is called a?
A long nerve fiber that conveys electrical impulses to other cells is called an axon. Axons are part of nerve cells (neurons) and are responsible for transmitting signals to other neurons, muscles, or glands. Some axons can be quite long, extending from the brain or spinal cord to distant parts of the body.
Axons and dendrites?
Axons are responsible for transmitting electrical signals away from the neuron cell body. Dendrites, on the other hand, receive incoming signals from axons of other neurons. Together, axons and dendrites play a crucial role in the communication between neurons in the nervous system.
What is the association of axons with nerves?
Axons are long projections of nerve cells that make up nerves. Nerves are bundles of axons transmitting information between the brain, spinal cord, and other parts of the body. Axons are responsible for carrying electrical impulses from one nerve cell to another, allowing for the communication necessary for proper functioning of the nervous system.
What are nerves composed of?
Nerves are composed of nerve cells; the long connecting parts of the nerve cells are called axons. The biochemistry of nerve cells is similar to that of other cells, but they do have an insulating layer, the myelin sheath, which gives them a relatively high concentration of fat.
