receptor

Reflex Arc

A nervous system structure that intakes the stimulus and “translates” it to electrical language understood by neurons

sensory (afferent) neuron

Reflex Arc

These are typically classified as the neurons responsible for converting various external stimuli that come from the environment into corresponding internal stimuli. They carry the sensory information from the receptor to the brain or spinal cord.

integration center

Reflex Arc

The brain or spinal cord where sensory information is sorted, “understood”, and a decision about responding to the sensory information is made. Reflexes may be spinal or cranial, depending on where the [term] is located

New cards

motor (efferent) neuron

Reflex Arc

A neuron located in the central nervous system that projects its axon outside the CNS and directly or indirectly controls effectors. The motor neuron carries the “do something” information to the effector.

Reflex Arc

A muscle or gland that responds to the motor neuron’s signal
