There are 2 types OS nerve fibers, called axons and dendrites. The axons carry nerve impulses away from the cellbody, while dendrites carry them towards the cell body.

corpus callosum
Do dendrites release neurotransmitters?
Not really, but sort of, eventually. Initially they receive neurotransmitters which are originally released by axon terminals into the synaptic cleft; then, after they have done their job of opening ligand-gated ion pores to allow sodium ions into the dendrite, which initiates a graded potential in the dendrite, they are then released so they can be re-absorbed and re-used by the axon terminals as new impulses reach the axon terminals.But functionally it is the axon which releases neurotransmitters, when an action potential causes it, so that dendrites can receive them. The dendrites only "release" them after their job is done, so they can be re-used.
John and Joe were born at the same time They both died on their eighteen-month birthday John lived in a home that had parents and siblings who spent a lot of time reading and playing with him Joe?
John's brain would have many more dendrites and connections all through the brain.
What are the differences between an opened brain injury and a closed brain injury?
There are two basic types: open head injuries and closed head injuries. Open head TBIs are a frightening mess. Whether the injury comes from a bullet, a baseball bat, or a high-speed collision, the result is always chaotic and distressing. The scalp bleeds a lot when it is cut, and when the skull is cracked or penetrated, pieces of it can get lodged in the brain. Because the brain is such a complicated tangle of tissue, it's extremely tricky to remove objects lodged inside a brain. That's why we put brain surgery right up there with rocket science in our everyday language.In a closed head injury, nothing penetrates your skull, but a closed head injury can be just as complicated and vicious as an open head injury, sometimes more so. During a closed head injury, the brain may slam against one portion of the skull, then bounce against the opposite side of the wall. Doctors call that a "coup-contracoup" injury, where two injuries occur from a single blow. One of the most common types of closed head injury is a concussion - a strong blow from an external force. If a person's head is whipped around, a small tearing effect called shearing occurs throughout the brain, resulting in a diffuse axonal injury. Axons are the hairlike extensions of nerve cells that transmit messages, so in a diffuse axonal injury, the messages either get mixed up, or they don't come through at all.
Why is there fat coating around the dendrites and axons?
The fat coating around the dendrites and axons is to insulate them.
Axons and dendrites is another word for?
Axons are the output element of a neuron, and dendrites are the input elements of a neuron.
Where is the dendrites located at?
dendrites are located at the nerves together with axons.
What are the two kinds of branches that extend from the cell body of a neuron what does each do?
The ones carrying the input are the dendrites, the ones carrying the output are the axons.
What are Axons and dendrites are part of?
cell
What are the processes of the system?
dendrites and axons
The cerebral cortex is the:a.gray matter, the axons and dendrites of neuronsb.gray matter, the cell bodies of neurons?
A.) The grey matter, the axons and dendrites of neurons.
What pairs lists the fiber like extensions that are components of neurons a axons and myelin b synapses and myelin c dendrites and axons d dendrites and synapses?
C. Dendrites and axons both extend from the cell body of the neuron in a branching fashion.
What are the processes of the nervous system?
dendrites and axons
What part of the nerve are Axons and dendrites?
cell
Axons and Dendrites are part of what kind of cell?
Neurons, of the nervous system. The dendrites receive impulses, and the axons send them to another neuron or an effector cell.
Are synaptic vesicles located at the ends of dendrites and axons?
No. They are located at the ends of axons, but not the dendrites. Please refer to the related links below to see an illustration.
