The peripheral nervous system.
by the brain throught the heart
messenger neurons
it's a single organ from the nervous system
You have thousands of nerves that are part of the PNS.Divisions of the peripheral nervous system include the afferent (sensory) division and the efferent (motor) division. The nerves coming from all the senses and the nerves going to glands and muscles are included.The efferent division is divided further into the somatic motor nervous system and thesomatic nervous system which includes all voluntary motor pathways outside the central nervous system.
true
Trigeminal nerve
No. There is no central nervous system - its just a DNA or RNA molecule coiled up in a protein.
The central nervous system, which consists of the brain and spinal cord, coordinates incoming sensory information and sends instructions to muscles and glands. This information processing allows for both voluntary and involuntary responses to stimuli.
Sensory neurons
The brain and spinal cord are part of the C.N.S.(Central Nervous System) The nerves from senses -> brain -> motor neuron -> muscle are part of the P.N.S. (Peripheral Nervous System)
Senses, such as hearing, taste, sight and smell, are transmitted by the spinal cord to the brain for interpretation. The brain and the spinal cord are the two main parts of the central nervous system.
