Chemical information in the form of neurotransmitters are received by receptors located on the dendrites and sometimes the soma (cell body) of the neuron.
Sensory and afferent nerves receive information from sensory organs.
In a simple model of the neuron, the dendrite receives information. In a more complex model, a neuron can have a synapse from other neurons anywhere except on the myelin sheath.

What is a penguin's sensory organs?
Special sensory neurons in sense organs that receive stimuli from the external environment.
Are sensory neurons organs?
No, sensory neurons are not organs. Sensory neurons are a type of nerve cell that carry information from sensory receptors to the central nervous system where it is processed. They are part of the nervous system but do not constitute organs themselves.
What neuron carries impulses from receptors to the central nervous system?
Neurons that convey sensory information are called 'sensory neurons' or "afferent neurones"
What are the three classes of neuron?
The three classes of neurons are sensory neurons, motor neurons, and interneurons. Sensory neurons transmit sensory information from sensory organs to the central nervous system (CNS), motor neurons carry signals from the CNS to muscles and glands to control movements, and interneurons facilitate communication between sensory and motor neurons within the CNS.
What is the difference between somatic sensory neurons and visceral sensory neurons?
Somatic sensory neurons detect stimuli from the skin, muscles, and joints. Visceral sensory neurons detect stimuli from internal organs such as the heart, lungs, and intestines. Both types of neurons transmit sensory information to the central nervous system for processing.
What does a sensory neurons do?
Sensory neurons are nerves that take in information from either the outside world, or from within the body itself. Sensory neurons communicate this information to the brain which then issues a response. Sensory nerves take in and communicate information about heat, cold, pressure, pain, position and more. detect, feel, and smell
What are the 3 types of neurone?
Sensory neurons, motor neurons, and interneurons. Motor neurons usually carry information to muscles and glands. Sensory neurons carry information from sense organs or free endings to the spinal cord or brain. Interneurons act as a go between.
Which neuron receives information?
Sensory neurons are responsible for receiving information from the external environment or internal body systems and transmitting it to the central nervous system. These neurons are specialized to detect various stimuli such as touch, pain, temperature, pressure, and chemical signals.
Which type of neurons carries impulses sense organs to the spinal cord or brain?
Sensory neurons
Which type of neurons impulses from sense organs to the spinal or brain?
Sensory neurons
Are neurons in the brain only interneurons?
No, neurons in the brain include interneurons as well as sensory neurons and motor neurons. Interneurons primarily communicate with other neurons in the central nervous system, while sensory neurons carry information from sensory organs to the brain and spinal cord, and motor neurons transmit signals from the brain and spinal cord to muscles and glands.
How do sensory neurons and motor neurons act in opposite ways?
Sensory neurons transmit signals from sensory receptors towards the central nervous system to detect external stimuli, while motor neurons transmit signals from the central nervous system to muscles and glands to initiate a response or action. In this way, sensory neurons bring information in and motor neurons send information out to carry out a response.
