A motor neuron is responsible for transmitting signals from the central nervous system to muscles or glands to stimulate movement or secretion. A relay neuron, also known as an interneuron, acts as a bridge between sensory and motor neurons, facilitating communication between them within the central nervous system. Essentially, motor neurons are involved in output or response, while relay neurons help process and integrate information.
The optic nerve (cranial nerve II) carries sensory information about light intensity to the brain as part of the afferent pathway in the pupillary reflex.
The substance that is produced and released by neurons in the brain is a hormone called dopamine. It acts as a neurotransmitter that sends signals between nerve cells.
Connector neurons are specialized bipolar or multipolar neurons of the central nervous system. Connector neurons are also known as interneurons and connect sensory neurons.
No. Neurons have a cover on a part called the axon. This is called a neurolemma. Not all axons have this covering. This cover acts like the cover on an electrical cord. It prevents it from short circuiting and increases the speed which the impulse travels.
The interneuron acts as a connector between afferent and efferent neurons in the central nervous system. It integrates and processes incoming sensory information before transmitting signals to the efferent neuron to produce a response.

A htm file is interpreted, not compiled. A browser acts as the interpreter.
In the presence of renal artery stenosis, the resistance in the afferent arteriole is increased. As compensation, Angiotensin II acts to constrict the efferent arteriole in order to achieve adequate profusion of the glomerulus. ACE inhibitors block the conversion of angiotensin I into angiotensin II. Without its vasoconstrictive effect, the efferent arteriole becomes dilated. This leads to a drop in GFR and may lead to renal failure.
Thalamus
A nerve cell found entirely within the central nervous system that acts as a link between sensory neurons and motor neurons.
carries an amino acid to its correct codon

Nicotine is a Sympathetic drug when it acts on synapse it has its Sympathomimetic action and it activates the neurons.
Thalamus is the important synapse site for afferent fibers traveling to the sensory cortex. It acts as a relay station, processing sensory information before transmitting it to the appropriate areas of the sensory cortex for further processing and perception.
