Definitions:

Chemoreceptors

Sensory receptors that detect chemical stimuli, either from the environment or within the body, and transmit this information to the nervous system.

Proprioceptors

Sensory receptors, found chiefly in muscles and tendons, that detect the motion or position of the body or a limb by responding to stimuli originating within the organism.

Glutamate

An important neurotransmitter in the brain that plays a key role in cognitive functions such as learning and memory.

Interneurons

Neurons that transmit signals between other neurons, especially as part of a reflex arc in the central nervous system.
