What is the pathway of an impulse in a reflex arc?
Sensory receptor, sensory neuron, interneuron, motor neuron, and muscle.
Where does the nerve impulse travel from the reflex arc?
The nerve impulse typically travels from the sensory neuron to the spinal cord, where it is processed by interneurons, and then to the motor neuron to elicit a response from the effector organ or muscle.
What connects the motor neurons to the sensory neurons?
What connects sensory and motor neuron is the impulse called interneuron or connector neuron are connected by means of electrical impulse called synape from sensory to motor neuron.
Are spinal nerves purely sensory nerves?
Spinal Nerves Are Both Sensory and Motor. Spinal nerves are not one or the other.
What is the difference between motor and sensory neurons?
The main difference is that motor neurons move signals away from the central nervous system and spinal cord where as sensory neurons move signals towards the central nervous system and spinal cord.
Describe the path an impulse would take for a reflex reaction?
When a sensory receptor detects a stimulus, an impulse is transmitted via a sensory neuron to the spinal cord. In the spinal cord, the impulse is processed and a response is generated, which is then sent via a motor neuron to the effector (muscle or gland) to carry out the reflex reaction. This entire pathway occurs rapidly and automatically without involvement of the brain.
Are the spinal nerve both sensory and motor?
motor
What are the types of spinal nerves?
sensory and motor
Spinal nerves are purely sensory and motor?
Spinal nerves are mixed nerves, meaning they contain both sensory and motor fibers. Sensory fibers transmit information from the body to the brain, while motor fibers carry signals from the brain to muscles, glands, and other effector organs. This dual function allows spinal nerves to both receive sensory input and initiate motor output.
Are spinal nerves primarily sensory or motor in function?
Spinal nerves have both sensory and motor functions. They carry sensory information from the body to the brain and transmit motor signals from the brain to the muscles to control movement.
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).
What is the sequence of blockade in spinal anaesthesia?
Motor sensory
