It is an accending tract carring information up to the brain until they reach the cerebral cortex. By large the specific pathways cross to the side of cnetral nervous system that is opposite to the location of their sensory receptors.
A typical neuron possesses a cell body called soma, dendrites and axon. The sensory nerve cells receiving information from the skin are pseudounipolar cells having two axon. One axon extends centrally towards the spinal cord and the other axon extends towards the skin. The soma of these nerve cells having neurofilaments of specialized proteins receive sensory information through electric and chemical signals called neurotransmitters.A typical neuron possesses a cell body called soma, dendrites and axon.

1. Sensory Receptors detect danger(eg. hot stove in this case) 2. Signal is sent through a sensory neuron to the spinal cord 3.Interneuron in the spinal cord relays the message to the motor neuron 4.Motor neuron sends a message to the effector(eg. muscle) 5. Hand jerks away Sensory neuron also sends a sinal to the brain. Sensation of the evernt is detected continuosly but usually after the defensive action has been taken.
soma
A simple reflex involves a direct pathway that includes only a sensory neuron and a motor neuron, resulting in an immediate, involuntary response to a stimulus, such as the knee-jerk reflex. In contrast, a complex reflex involves multiple neurons and often includes interneurons, allowing for more intricate processing and integration of information, which can lead to a more coordinated response, such as withdrawal from pain. Simple reflexes are typically faster and more straightforward, while complex reflexes can involve higher brain functions and emotional responses.
The leg wouldn't be able to receive or transmit impulses and information from the central nerves system CNS to the muscle and glands
A sensory neuron is one that brings information about environmental simuli to the brain. It may also be called an afferent neuron.
Both the spinocerebellar tract neuron and the sensory neuron from the quadriceps femoris are a type of primary sensory neuron responsible for conveying proprioceptive information to the central nervous system. They both have a cell body located in the dorsal root ganglion and an axon that enters the spinal cord to transmit sensory information.
Receptor → Sensory Neuron → Associative Neuron→ Motor division →Effectors
Between the sensory neuron and the motor neuron lies the interneuron. Interneurons communicate and process information within the central nervous system, helping to integrate and coordinate sensory inputs with appropriate motor outputs.
The reflex arc includes the sensory neuron (sensory intake) to the motor neuron (motor response). This two neuron arc is the fastest. Many times an interneuron at the level of the spinal cord is involved. It passes information to the brain more slowly. It is like an "incident report".
The synaptic terminal of a sensory neuron is located either in the dorsal root ganglion (if it is a pseudo-unipolar neuron) or directly in the spinal cord (if it is a bipolar neuron). This is where the sensory neuron connects with other neurons to transmit sensory information to the central nervous system.
love
actually we must say all neurons receive information. there are three types of neurons: 1.sensory neuron 2.motor neuron 3.relay neuron the sensory neurons receive information from receptor cells in sense organs and pass the information from sensory neuron to the other and pass the info to spinal cord where they are received by relay neuron. this neuron in turn passes the info to motor neurons which pass the info to cells in effectors and action is performed.relay neurons are messengers between sensory neuron and motor neuron in spinal cord.
Motor Neuron and Sensory Neuron
Sensory neuron
Dendrites are the part of the neuron specialized to receive information from other neurons and the axon transmits signals to other neurons or to muscles or glands.
The sensory (afferent) neuron has a cell body located in the posterior root ganglion of the spinal nerve. This neuron carries sensory information from the peripheral receptors to the central nervous system.
