Pseudounipolar cells

From Wikipedia, the free encyclopedia

Pseudounipolar cells (Pseudo- false, uni- one) are sensory neurons in the peripheral nervous system. These neurons contain a long dendrite and a small axon that connects to the spinal cord.

[edit] Anatomy

The dendrite of these neurons are located in the nerves coming from the body. The cell bodies are located in the dorsal root ganglion just next to the spinal cord. The axons protrude through the dorsal root and into the posterior horn of the spinal cord.

[edit] Signal Pathway

The signal is conducted through the nerve (dendrite) to the dorsal root ganglion (cell body), then through the dorsal root (axon) ending at the sensory nuclei in the posterior horn of the spinal cord.
