Somatic Nervous System - Definition, Function and …

WebThe sensory-somatic nervous system is made up of cranial and spinal nerves and contains both sensory and motor neurons. Sensory neurons transmit sensory information from the skin, skeletal muscle, and sensory organs to the CNS. Motor neurons transmit messages about desired movement from the CNS to the muscles to make them contract. WebThese molecules are unconventional in that they are not stored in synaptic vesicles and may carry messages from the postsynaptic neuron to the presynaptic neuron. Also, rather than interacting with receptors on the plasma membrane of their target cells, the gasotransmitters can cross the cell membrane and act directly on molecules inside the cell.
