Layer of nerve tissue made up of sensory neurons that respond to light?
The retina is the layer of nerve tissue in the back of the eye that contains sensory neurons called photoreceptors. These photoreceptors, specifically rods and cones, respond to light and convert it into electrical signals, which are then transmitted to the brain via the optic nerve, allowing us to perceive visual information.
What part of brain is sensory?
The sensory strip is a thin layer of cerebral cortex involved in processing feelings of touch, for instance. The feedback loop from your fingers (when typing, let's say) to your brain, goes to the sensory strip. Without functioning neurons in this area of your brain, you would not perceptibly "feel" anything.
What is the main function of sensory neuron?
detect feel and smell
How is a nervous system like a communications system?
Signals are sent along the nerves of your body to your brain, where they are interpreted. The brain may send signals back instructing muscles to contract or expand, causing one's arm or other appendage to move.
What is the difference between the the motor neuron and the sensory neuron based on their function?
Motor neurons are responsible for transmitting signals from the central nervous system to muscles or glands, allowing for voluntary movement or secretion. On the other hand, sensory neurons detect information from the external environment or the body and transmit it to the central nervous system, enabling us to perceive sensory stimuli such as touch, temperature, pain, or sound. In summary, motor neurons control movement and actions, while sensory neurons provide information about the external world to the brain.

What is your spinal cord?
The spinal cord transmits messages from the brain to control body functions such as muscles, bladder, bowel, heart, kidney function etc, and to relay sensory information back to the brain.
What are five facts about the spinal cord?
- The spinal cord is the body's main nerve trunk. - It is about 18 inches long. - It is about as thick as a man's little finger. - It runs down the back from the medulla oblongata, at the base of the brain. - The spinal fluid acts as a cushion to protect the cord from damage.
Sensory neuron is to motor neuron as?
Sensory neuron is to motor neuron...as feedback system is to control system. The motor neurons send signals from the brain to control the body. The sensory neurons send signals from the body back to the brain.
What part of the brain stem helps coordinate movements?
The cerebellum, located at the back of the brain, is the part responsible for coordinating movements. It receives information from the sensory systems and integrates it to control balance, posture, and voluntary movements.
What is the function of the relay nerve?
Neurons are only capable of carrying a message in one direction. Sensory neuronsare afferent neurons, meaning they only relay information to the brain. Motor neuronsare efferent neurons, meaning they carry information from the brain to the target. In certain instances, it would take too long for information to go to the brain and then come back with an action in response. Instead, relay neurons, or interneurons relay information from sensory neurons to motor neurons, bypassing the brain. Think about touching a blazing hot stove. If the signal went all the way to your brain and back, your hand would be much more damaged than the instant jerk away from the stove that normally happens.

In what direction is information carried along the sensory neuron?
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.
What is the main function of sensory neuron?
detect feel and smell
What is meant by motor peripheral nerves?
peripheral nerves are either motor, meaning that they are involved in motor activity such as walking, or sensory, meaning that they carry sensory information back to the CNS
Does the auditory nerve have blood in it?
No. Nerves are not blood-filled. They are a bundle of fibers that carry information from parts of your body back to your brain, where your brain then processes that information.
What kind of neuron sends a message from the brain to the muscles in a persons arm to control the movement involved in putting clothes on?
There are basically two kinds of neurons- sensory and motor. Motor neurons are responsible for passing on messages from the brain, to the effector muscles, while performing a voluntary action (they also do that for involuntary actions) Sensory neurons on the other hand, detect a stimulus, and pass on the message to the brain, which analyses the information, decides the course of action, and passes on the message back through the motor neuron, to the effector muscles.
