Sensory receptor, afferent neuron, efferent neuron, effector organ.
The most simple nervous system pathway is the monosynaptic reflex arc. It involves only two neurons: a sensory neuron that detects a stimulus and a motor neuron that responds to the stimulus by causing a muscle to contract. This pathway allows for rapid and automatic responses to stimuli, such as when you touch something hot and quickly pull your hand away.
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.
Central & Peripheral Edit: I don't think the last person read the entire question. Central (CNS) and Peripheral (PNS) are the two major divisions of the nervous system but the question is asking specifically about the central. Two major division of the central nervous system (structurally) are White matter and Gray matter.
simple-> doesnt coordinate activities unless there is a ganglia complex -> has a true brain with sensory structure that coordinates acitivties efficiently
The major organs of the nervous system include the brain, spinal cord, and peripheral nerves. The brain controls cognitive functions, sensory perception, and voluntary movements. The spinal cord serves as a pathway for transmitting information between the brain and the rest of the body, while peripheral nerves extend from the spinal cord to innervate various organs and tissues throughout the body.
Igneous rocks are the major group of rocks involved in Pathway 1. This pathway involves the formation of rocks from the cooling and solidification of magma or lava. Examples include granite and basalt.
The brain is a major organ of the nervous system
The nervous tissue.
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!
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"
