What is a is a long bundle of neurons that carries messages to and from the body to the brain that is responsible for very fast lifesaving reflexes.?
Spinal Cord
How can neurons carry messages to the brain?
The long bundle of neurons that carries messages to and from the body to the brain and is responsible for very fast, lifesaving reflexes is called the? Spinal cord.
Neurons that serve as links between the sensory neuron and the motor neurons?
interneurons also known as: ASSOCIATION NEURONS
What is the pathway called that signals travel along during a reflex?
Sensory neurons which trigger reflexes are called nociceptive neurons. After entering the dorsal root of the spinal cord, the nociceptive neuron branches into two terminals: one terminal synapses with an interneuron - a localised neuron which is located entirely within the grey matter of the spinal cord, and this in turn synapses with a motor neuron which then triggers the fast reflex action. The reflex is initiated solely within the spinal cord & doesn't involve the brain at all, but at the same time, the second branch of the nociceptive neuron synapses with a sensory neuron which goes to the brain; the brain then registers the sensation of pain, and can also initiate further motor action if necessary.
What Neurons in center of the spinal cord that receives information from the sensory neurons?
Interneurons.
Do reflexes always involve the spinal cord?
Yes, the spinal cord controls ALL of your reflexes!
Spinal reflexes are produced in what?
Introduction. Spinal cord reflexes are simple behaviors produced by central nervous system (CNS) pathways that lie entirely within the spinal cord. The sensory afferent fibers that evoke these reflexes enter the spinal cord and activate spinal motor neurons directly or through a chain of one or more spinal interneurons
What part of the brain controls simple reflexes that do not involve the brain?
spinal cord
What part of the central nervous system controls reflexes?
The spinal cord controls reflexes. When a sensory stimulus is detected, the signal is sent to the spinal cord, which then produces a reflex action without needing input from the brain. This allows for quick responses to potential threats or dangers.
What neurons that carry impulse to the brain and spinal cord called?
These are called efferent neurons. The one that carry impulses away are afferent. Afferent (A) are away (A).
CAN reflex action controlled by spinal cord?
Simple reflexes are controlled by the spinal cord. The message travels from the sense receptors near the skin through the afferent nerve fibers to the spinal cord. In the spinal cord, the messages are relayed through association neurons to the efferent nerve fibers, which carry them to the muscle cells that cause the reflex movement.

Which carries messages to the brain?

Nerve impulses travel to the muscles from the spinal cord through?
afferent neurons
What carries impluses towards the brain and spinal cord?
The sensory neurons carry impulses through the spinal cord to the brain.
Most of the neurons in the brain and spinal cord are?
