The main components of the analyzer are: the working organ, the efferent neuron; receptor,communication channel, central department; neurons of the cerebral cortex , neuroglia; pre- and postganglionic autonomic neurons.

The main components of the analyzer are:<br />- Receptor: The receptor is the sensory organ that receives stimuli from the environment. It can be a sensory cell, a sensory organ, or a sensory system.<br />- Communication channel: The communication channel is the pathway through which the receptor sends information to the central department. It can be a nerve fiber, a nerve impulse, or a neurotransmitter.<br />- Central department: The central department is the processing center of the nervous system. It receives information from the receptor and sends instructions to the efferent neuron.<br />- Efferent neuron: The efferent neuron is the motor neuron that carries instructions from the central department to the effector organ.<br /><br />The other options provided are not the main components of the analyzer. Neurons of the cerebral cortex and neuroglia are part of the central nervous system, while pre- and postganglionic autonomic neurons are part of the autonomic nervous system.
