What do sensory neurons do?
Sensory neurons are the nerve cells that are activated by sensory input from the environment – for example, when you touch a hot surface with your fingertips, the sensory neurons will be the ones firing and sending off signals to the rest of the nervous system about the information they have received.
What does sensory neurons mean in medical terms?
Sensory neuron: A neuron that receives electrical input signals from sensory cells and from other neurons.
What is the meaning of sensory nerves?
Definitions of sensory nerve. a nerve that passes impulses from receptors toward or to the central nervous system.
Where are sensory neurons located and what do they do?
The cell bodies of the sensory neurons are located in the dorsal ganglia of the spinal cord. The sensory information travels along afferent nerve fibers in a sensory nerve, to the brain via the spinal cord.
Which of the following is a synonym for sensory neurons?

What are sensory receptors in psychology?
Sensory Receptors are specialized neurons or nerve endings that respond to changes in the environment by converting energy from a specific stimulus into an action potential (a process known as transduction).

Where does the signal go in a sensory neuron?
The fiber that carries the signal away from the cell body is called an axon. In sensory neurons, the axon is short. The axon communicates with the spinal cord, and at the end of the axon the neuron ends. The nerve fibers are protected, insulated and nourished by a pad of fat called a myelin sheath.
Which is the best description of a neuron?
Neuron Types 1 Sensory Neurons. The sensory neurons convert signals from the external environment into corresponding internal stimuli. 2 Motor Neurons. These are multipolar and are located in the central nervous system extending their axons outside the central nervous system. 3 Interneurons. They are multipolar in structure. …
