Label the following anatomical features of a typical neuron: the cell body, also known as the perikaryon, which contains the axon, endoplasmic reticulum, Golgi apparatus, cytoskeleton, and synapses. Place your cursor over each of these structures to learn more about them. You can also click on a structure to view the related section.
The nucleus is a large, round organ inside a neuron that houses the deoxyribonucleic acid (DNA) synthesized by the cell. The nucleus has a double membrane punctuated with pores, which allows it to interact with the surrounding cytoplasm. The nucleus can be as small as three micrometers, but larger neurons have larger nuclei. The axons are the nerve cells’ main organ, and they carry signals across the synapse to communicate with the rest of the brain.
A typical neuron is composed of a cell body, dendrites, and a single axon, or messenger RNA, that extends for approximately a meter or more, depending on the species. Axons terminate in tiny branches with cytoplasmic enlargements, which are called nerve endings. Typical neurons are located in the brain and spinal cord, but there are also sensory cells in various organs.
An axon is a long, thin tube that carries information from one neuron to the next. Axons travel up to one meter, depending on their species, and have few branches. The axon terminal is where the signal that travels across the synapse is sent. The axon is the most common type of neuron and is found in the central nervous system, while sensory neurons are found throughout the body.
A typical neuron is made up of the cell body, axons, and dendrites. The axon is the longest part of the cell, and the dendrites are the shortest. The axons are long enough to travel up to a mile, but in humans, they are shorter. The axons are axons.
The typical neuron has three main anatomical components: the axon, dendrites, and synapses. The axon is a long, thin tube that is connected to the post-synaptic cell. The synapse is the region of the plasma membrane that contains the dendrites. The axon is the most important part of a neuron, and the dendrites are the ones that serve this purpose.
A typical neuron has three main anatomical features: the cell body, dendrites, and an axon. Axons can travel up to a meter, depending on the species. They also end in small branches called nerve endings. Although most neurons are found in the central nervous system, there are also sensory neurons in other areas of the body. Anatomy of the brain and spinal cord are the most obvious parts of the brain.
The nucleus of a neuron is a large, round organ that contains masses of chromatin. The nucleus is also the cell’s main organ, and contains the axon and deoxyribonucleic acid (DNA). The axon is the source of the signal in the neuron. In addition to the axon, neurons have two other main structures.
The typical neuron consists of a cell body, dendrites, and a single axon. In the brain, the axon extends up to one meter, depending on the species. The axon and dendrites are both part of the central nervous system, but they can be found in any part of the body. In the peripheral nervous system, the neurons are distributed throughout the brain, the spinal cord, and the somatic and autonomic nerves.
Axon: Axons are axons that extend from the cell body. They contain bundles of microtubules and neurofilaments. The axon is surrounded by dendrites, which are fibrous roots that branch out from the cell body. Axons are often indistinguishable from each other. The idealized axon has one axon, while the dendrites have two or more.
