Facet Cell
A facet cell is a type of cell found in the vertebrate nervous system. These cells are primarily located in the spinal cord and are involved in the transmission of sensory information from the body to the brain. The term "facet" is derived from the Latin word "facies", meaning "face", and refers to the flat, face-like appearance of these cells.

Structure and Function[edit | edit source]
Facet cells are a type of neuron that are primarily located in the spinal cord. They are involved in the transmission of sensory information from the body to the brain. This includes information about touch, temperature, pain, and proprioception (the sense of the relative position of one's own parts of the body and strength of effort being employed in movement).
Related Terms[edit | edit source]
- Neuron: A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways, but there is one key difference between neurons and other cells. Neurons are specialized to transmit information throughout the body.
- Spinal Cord: The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid.
- Sensory Information: Sensory information is data received through the senses such as sight, sound, taste, touch, and smell. Sensory information is passed from the sensory organs to the brain via the nervous system.
