| There are how many cranial nerves? | 12 |
| There are how many spinal nerves? | 31 |
| Anterior Spinal Nerves | Motor neurons |
| Posterior Spinal Nerves | Sensory neurons |
| Nerve Plexus | Intersecting nerves |
| Cervical Plexus | Head and neck |
| Brachial Plexus | Arm and hand |
| Lumbar Plexus | Abdomen, low back and genitalia |
| Sacral Plexus | Posterior hip, legs and feet |
| Dermatones | Skin area specific to sensory nerve root |
| Myotomes | Group of skeletal muscles innervated by single spinal segment |
| Parasympathetic Nervous System | Rest & digestion, Slows down heart rate, Maintains homeostasis, Housekeeping system |
| Sympathetic Nervous System | Fight or flight, Processes not needed curing stress situation are suppressed, Speed up heart rate |
| Autonomic Nervous System (ANS) | Control of involuntary systems and is divided into Parasympathetic and Sympathetic Nervous Systems |
| Touch | General sense, Heat, cold, pressure, pain and movement |
| Taste | Gustatory glands (taste buds) mediate, Chemosensitive, Strongly influenced by smell |
| Olfaction | Chemoreceptors, Strongest sense linked to memory |
| Vision | Photoreceptors |
| Hearing | Mechanoreceptors, Sound waves or vibrations, Hit tympanic membrane |
| Exterorecptors | Stimulus origination from outside of body |
| Proprioceptors | Responds to movement and position |
| Interoceptors | Respond to stimuli from inside body |
| Chemoreceptors | Chemical stimuli, detect smell taste and changes in blood chemistry |
| Mechanoreceptors | Detect tactile pressure, blood pressure, vibration, stretching, muscle contraction, proprioceptions, sound and equilibrium |
| Photoreceptors | Sensitive to light |
| Rods | Photoreceptors that detect black, white and gray |
| Cones | Photoreceptors that detect color |
| Nocireceptors | Photoreceptors that detect pain in most bodily tissues |
