What are the 5 parts of a nerve cell?
The structure of a neuron: The above image shows the basic structural components of an average neuron, including the dendrite, cell body, nucleus, Node of Ranvier, myelin sheath, Schwann cell, and axon terminal.
How many organelles are in a nerve cell?
Thus, each nerve cell has a cell body containing a nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, and other organelles that are essential to the function of all cells (Figure 1.3).
Which part of the nerve cell contains the nucleus and organelles?
soma
Also known as a soma, the cell body is the core section of the neuron. The cell body contains genetic information, maintains the neuron’s structure, and provides energy to drive activities. Like other cell bodies, a neuron’s soma contains a nucleus and specialized organelles.
Which nerve is shown by 4?
(c) The nerve shown by 4 is association neuron. It is present in the gray matter of the spinal cord. It receives the sensory impulse, interprets it and generates impulse.
What is a nerve cell?
(nerv sel) A type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current. Also called neuron.
How do you identify a nerve cell?
The characteristic features to identify a nerve cell are:
- A. Cell body with branched cytoplasmic extensions at one end long projections at the other end.
- B. Rounded or oval cells with bilobed nucleus and cytoplasmic granules.
- C. Spindle shaped cell with a big central nucleus.
- D.
What organelles are in a nerve cell?
At the ultrastructure level, a nerve cell, like any other type of animal cell, contains different types of organelles that keep them alive and allow them to remain functional. These include such cell organelles as a nucleus, nucleolus, E.R, golgi apparatus and the mitochondria among others.

What are the 3 parts of a nerve cell?
All the human body neurons have three parts, a cell body, an axon, and dendrites. The nerve cell parts consist of the following: The cell body in a nerve cell is its core. It is also called soma.
