What made up the midbrain?
The "midbrain" is called the Mesencephalon, considered part of the brain stem. The following are connected to the "midbrain": tectum, tegmentum, ventricular mesocoelia, cerebral peduncles. The "midbrain" is made up of Gyrus (brain ridges) surrounded by one or more sulci (brain fissures or depressions). The structure of the brain is made up of Neurons. Neurons are made up of the following regions: Dendrite, soma, Nucleus, Axon, Myelin sheath, Node of Ranvier, Schwann cell, Axon Terminal. Consisting of similar materials as most cells (DNA...etc).
What are the parts of the neuron that the messages travels through?
The message travels through the axon and Schwann cells (which make up the axon) as an electrical message. When it reaches the dendrite, it is converted into a chemical message where it can be picked up by another neuron.
What are nerve axon tracks made of?
The axons of nerve cells are surrounded by myelin sheeths - a protective covering that allows for saltatory conduction down the axons, increasing speed and decreasing loss of signal. Axons make up the tissue known as "white matter."
What structure in the neuron helps to speed up the transmission of the action potential?
The myelin sheath, which is made of fatty tissue wrapped around the axon, helps to speed up the transmission of the action potential by insulating the axon and allowing the action potential to jump between the nodes of Ranvier. This process is known as saltatory conduction and helps to increase the speed of signal transmission in neurons.
What part of the neuron can conduct an action potential?
The axon of a neuron is responsible for conducting an action potential. This is made possible by the presence of voltage-gated ion channels along the axon membrane that allow for the propagation of electrical signals.
The axon is made up of?

The material surrounding the axon that increases the speed of the nerve impulse is?
The material surrounding the axon that increases the speed of the nerve impulse is the myelin sheath. It is made of fatty substances and acts as an insulator, allowing for faster conduction of the electrical signal along the axon. Nodes of Ranvier are the gaps in the myelin sheath where the signal jumps between to speed up transmission.

What is the fatty materiel that covers the axon and helps with nerve impulses?
It is called as myelin sheath. It acts as an insulator of the electrical wire. It is made up of cells.

What is meant when axon is described as myelinated?
Most axons are covered with a protective sheath of myelin, a substance made of fats and protein, which insulates the axon. Myelinated axons conduct neuronal signals faster than do unmyelinated axons.
What part of the neuron can conduct an action potential?
The axon of a neuron is responsible for conducting an action potential. This is made possible by the presence of voltage-gated ion channels along the axon membrane that allow for the propagation of electrical signals.
What speeds up the passage of electrical messages by acting as a insulator of the neuronal signal?
Myelin is a fatty substance that wraps around the axon of a neuron, acting as an insulator that speeds up the transmission of electrical signals. By insulating the axon, myelin helps the signals propagate more efficiently and quickly along the neuron.
Where does neuron charge build up before fired to the axon?
Before a neuron fires, the charge builds up at the axon hillock, the region where the axon meets the cell body (soma). This area integrates incoming signals from dendrites and determines whether the threshold for firing an action potential is met. If the threshold is reached, an action potential is generated, and the electrical signal travels down the axon.
What does the sheath do in a nerve cell?
The myelin insulating sheath speeds up signal propagation down the axon. It also acts like the covering on any electric cord. It only covers the axon and since it is made of fatty materials, it appears white. The cell and dendrites appear gray.
