Sensory receptor, afferent neuron, efferent neuron, effector organ.
The nervous system contains bundles of fibers, cells, motor neurons, and enteric nervous system. It also contains the autonomic nervous system and axons.
1. Omg so scared! 2.i got to pee! 3.die of keeping pee inside 4.no more you.
Brain, synapses, nerves, and sheaths
The reflex arc is the simplest neural circuit.
During a pain withdrawal reflex impulses are sent through different nerves and to the spinal cord. This reflex does not make it to the brain but only to the spinal cord. We call this involuntary action because we dont control reflexes. The sensory neurons are the first to recieve the impulse, then they travel to the interneurons, or associative neurons, and then they go to the motor neurons which carries the impulse to the central nervous system. Then the effector is the response, so in this case your musscle will contract.
simple-> doesnt coordinate activities unless there is a ganglia complex -> has a true brain with sensory structure that coordinates acitivties efficiently

The brain is a major organ of the nervous system
what are the major elements of concerto
the three major parts of our nervous system are:nerve cells,brain and spinal cord
The nervous tissue.
Feedback Loop
Neurology is the branch of medicine concerned with the study and treatment of disorders of the nervous system. The nervous system is a complex, sophisticated system that regulates and coordinates body activities. It has two major divisions 1.Central nervous system: the brain and spinal cord 2.Peripheral nervous system: all other neural elements, such as eyes, ears, skin, and other "sensory receptors"
The major parts of the nervous system are the brain, spinal cord, and nerves.brain spinal cord and neuron or nerves
The major system of the nervous system is the brain. Also the spinal cord helps the brain so it is a big help in the nervous system. hope i answered your question!
