Sensory neurons are adapted to their function through specialized structures that enhance their ability to detect stimuli. They possess receptor endings that are sensitive to specific types of stimuli, such as light, sound, or pressure, allowing for the transduction of these signals into electrical impulses. Additionally, their long axons facilitate rapid transmission of information to the central nervous system, ensuring quick responses to environmental changes. The myelination of these neurons further increases conduction speed, optimizing the sensory processing of incoming information.

How may you Explain the role of sensory and motor neurones in a reflex arc.?
what is the role of sensory and motor neurones in a reflex arc
What carries information to the brain to be interpreted?
Sensory neurons are responsible for carrying information from sensory receptors to the brain. These neurons transmit signals related to touch, taste, smell, sight, and hearing which are then interpreted by the brain.
What is the connection between sensory nerves and the neurons in the brain?
Both use neurones which transmit in via action potential and synaptic transmission. Sensory neurones include pain neurones which enter directly into the brain, which perceives the stimulus as pain and gives emotional and motor responses accordingly. Sensory neurones also perceive homeostasis, in that they sense stimuli outside physiological norms and change homeostasis in order to rectify the problem. All motor and limbic (emotional) outputs from the brain are stimulated and therefore initiated by sensory neurone inputs. The spine relys information from peripheral sensory neurones to the brain, and is the literal connection between sensory neurones and the brain.
Why do the sensory neuron has short axon and long dendrites?
sensory and motor neurons are sometimes very long so that the impulses can be carried away from the body very quickly. in the motor neuron the impulses "jump" over the fatty tissue to the Node Of Ranvier.
Three differences between sensory neurone and motor neurone?
# Motor neurones have cell bodies inside the Central Nervous System (CNS) whilst in sensory neurones the cell body is located outside of the CNS # Motor neurones transmit impulses from the CNS to the effector which brings about a response to the situation, sensory neurones transmit impulses from to the CNS from the receptor. # Sensory neurones transmit impulses as a result of external stimuli such as pressure, light, temperature etc. Motor neurone transmit impulses passed along the CNS to the effector.
Why does the body have both sensory and motor neurones?
the body has both sensory and motor neurones because the sensory neurones sense what is happening and sends the message along and like a motor the motor neurones pass on the message constantly round and round until it reaches its destination
Similarities of motor and sensory neurons?
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.

What is a sensory neurones?
A sensory neuron is one that brings information about environmental simuli to the brain. It may also be called an afferent neuron.
DIvision of the nervous system brings sensory information to the central nervous system?
The afferent neurones or Sensory neurones. Further divided to 2 subtypes, the visceral (from inner organs) and somatic (from skin). There is also the cranial nerves which provide information to the CNS.
What is the basic unit of structure and functon of the nervous system?
The nervous system is used to trasmit information around the body. It is made of two systems: the central nervous system (which consists of the spine and brain) and the peripheral nervous system (which consists of neurones and receptors). There are three types of neurones: sensory neurones, relay neurons, and motor neurones.
What neuron carries impulses from receptors to the central nervous system?
Neurons that convey sensory information are called 'sensory neurons' or "afferent neurones"
What is the most probable reason for procaine preventing pain?
It prevents impulses passing along the sensory neurones to the brains.
Type of neurones along a reflex arc?
the sensory receptor begins then the Relay neuron and final the motor neuron
