A neuron is an excitable cell, which conveys an electric impulse when adequately stimulated. The structures are: the dendrites (inputs), the cell body (soma), the nucleus, the axon (the output, which can be thin and long up to a meter), with a Myelin sheath on the longer axons (made up of Schwann cells in the peripheral nervous system, or oligodendrocytes in the central nervous system, separated along the axon by the Nodes of Ranvier), axon terminal branches, ending with a terminal button which would form the beginning of a synapse when connecting to another neuron, or a motor end plate if connecting to a muscle cell.
What else can I help you with?
Is dendrites a structure of a neuron?
Yes, dendrites are the branching structures of a neuron that receive incoming signals from other neurons and transmit them to the cell body. They play a crucial role in integrating and processing information within the brain.
What are the structures that carry messages toward a neuron's cell body?
Dendrites are the structures that receive messages and carry them toward a neuron's cell body. They serve as the main receiving region of a neuron, collecting signals from other neurons and transmitting them to the cell body for further processing.
Which branching structures carry information toward the cell body of a neuron?
Dendrites are the branching structures that carry information toward the cell body of a neuron. They receive signals from other neurons and transmit them to the cell body for processing.
What portion of a neuron forms the presynaptic neuronal membrane?
The axon terminals of a neuron form the presynaptic neuronal membrane. These structures contain synaptic vesicles that store neurotransmitters for release at the synapse.
What two structures are closely associated at the neuromuscular junction?
The two structures closely associated at the neuromuscular junction are the motor neuron and the muscle fiber. The motor neuron releases the neurotransmitter acetylcholine, which binds to receptors on the muscle fiber, initiating muscle contraction.

What are the neuron structures that carry impulses to the cell body called?
Dendrites.
name the neuron structures that receive incoming information and the structures through which information exits (or is passed on) from the cell?
Dendrites
What is a part of a neuron affected by multiple sclerosis?
the myelin sheaths. The disease is classified as demyelinating , which is also known as the degeneration of the myelin structures in the neuron.
What are the structures that carry messages toward a neuron's cell body?
Dendrites are the structures that receive messages and carry them toward a neuron's cell body. They serve as the main receiving region of a neuron, collecting signals from other neurons and transmitting them to the cell body for further processing.
Which branching structures carry information toward the cell body of a neuron?
Dendrites are the branching structures that carry information toward the cell body of a neuron. They receive signals from other neurons and transmit them to the cell body for processing.
What are the small branchlike structures of the neuron that receive signals from receptors or other resources?
Dendrite
Which bulb-shaped structures found at the end of neurons form connections with the dendrites and somas of other neurons and allow information to pass from neuron to neuron?
Axon Terminals
What might a neuron have?
Neurons have lots of things. They have the usual cellular apparatus, a membrane, a nucleus, mitochondria, etc. They can also have some distinctive neuron type structures, which are axons and dendrites.
How many main structures or groups of structures make up every neuron?
Every neuron consists of three main structures: the cell body (soma), dendrites, and an axon. The cell body contains the nucleus and other organelles, dendrites receive incoming signals from other neurons, and the axon transmits signals to other neurons or muscles.
What portion of a neuron forms the presynaptic neuronal membrane?
The axon terminals of a neuron form the presynaptic neuronal membrane. These structures contain synaptic vesicles that store neurotransmitters for release at the synapse.
