The largest part of a cell, the cell body holds all of the general parts of a cell as well as the nucleus, which is the control center. The nucleus contains the cell's genetic material (DNA, located in the chromosomes).
cell body In a neuron, the part that contains the nucleus and most of the cytoplasm and the organelles. PICTURE 1 PICTURE 2 ...
cell body Portion of a nerve cell that includes a cytoplasmic mass and a nucleolus, and from which the nerve fibers extend.
cell culture (tissue culture)The culture of single cells or tissues to form callus and then to develop whole plants asexually.
a cell body which contains the nucleus;
a number of short fibers — dendrites — extending from the cell body
a single long fiber, the axon.
The nerve impulse is conducted along the axon.
The cell body of a neuron is supported by a complex meshwork of structural proteins called neurofilaments, which are assembled into larger neurofibrils.
Most neurons are referred to as "bipolar"; they have a cell body and many small extensions, called dendrites, at one end which receive information (Fig. 1).
The size of post-mitotic neurons depends on the size of the cell body, axon and dendrites. In vertebrates, neuron size is often a reflection of the number of synaptic contacts onto the neuron or from a neuron onto other cells.
Be able to diagram a typical neuron and its three areas: dendrite, axon, and cell body.
Know the characteristics of the various types of animal tissues.
Some of the cells are stellate in shape, with ill-defined cell body, and their fine processes become neuroglia fibers, which extend radially and unbranched (Fig. 623, B) among the nerve cells and fibers which they aid in supporting.
Neurons have a cell body which refers to that part of the cell in which the nucleus is situated. Some have extensions called dendrites and axons. The axons can be several feet long, reaching from your spinal column to your big toe.
A filamentous process extending from the cell body of a neuron and conducting the nerve impulse; an axon.
nerve impulse
A rapid, transient, self-propagating change in electric potential across the membrane of an axon.
elongated process of a nerve cell for conduction of impulses away from the cell body; contrast to dendrite

axon
a typically long outgrowth, or process, from a neuron that carries nerve impulses away from the cell body toward target cells.

Bacillus
a bacterial cell that is rod-shaped (i.e. longer than it is wide).
It's a cell that has three basic parts: flagella, collar, and cell body. Sponges use the flagella to move when they are larvae. The flagella and collar work together to gather food. Sponges even use the choanocyte when it's time to reproduce. Wow! ...
Whereas botulinum neurotoxins remain at the neuromuscular junction, tetanus toxin is retrogradely transported along the axon to the cell body, where it is released into the intersynaptic space and is internalized by adjacent inhibitory interneurons.
