| Question | Answer |
| Olfactory | sense of smell |
| Optic | vision |
| Oculomotor | movement of eyes and eyelids |
| Trochlear | movement of eyes |
| Trigeminal | mastication |
| Abduces | eye movement |
| Facial | facial expressions |
| Vestibulocochlear | hearing and equilibrium |
| Glossopharyngeal | swallowing and taste |
| Vagus | autonomic motor |
| Accessory | sternocleidomastoid |
| Hypoglossal | tongue |
| Alzheimer disease | progressive dementia |
| Bell Palsy | one side of the face |
| Cerebrovascular accident (CVA) | most common brain disorder |
| Shingles | caused by varicella-zoster virus |
| Parkinson Disease | tremors |
| Meningitis | acute inflammation |
| Hydrocephalus | obstruction in the normal flow of cerebrospinal fluid |
| Nervous system | CNS and PNS |
| Ganglia | knots of nerve call bodies |
| Afferent Division (sensory) | transmits impulses from peripheral organs to the CNS |
| Efferent Division (motor) | transmits impulses from the CNS out to the peripheral organs to cause an effect or action |
| Neuron | transmits impulses |
| Neuroglia | nerve glue, no nerve impulses , it supports, nourish, and protect |
| Three parts of the neurons | cell body, one or more dendrites, and a single axon |
| Myelin Sheath | white, fatty substance that surrounds an axon |
| Grey Matter | Unmyelinated fibers |
| Nodes of Ranvier | unmyelinated regions between the myelin segments |
| Schwann cells | in the PNS this produces myelin |
| Neurilemma | covering of schwann cells , plays a role in regeneration of nerve fibers |
| Oligodrendrocytes | In the CNS this produces Myelin |
| Synapse | communication between two neurons |
| Neurotransmitter | chemical |
| Reflex | an automatic involuntary response to some change, coughing, sneezing, and reaction to painful stimuli |
| CNS consists of | brain and spinal cord |
| Meninges Three Layers | Dura Mater, Arachnoid, and Pia Mater |
| Dura Mater characteristics | though, white fibrous connective tissue |
| Arachnoid | resembles cobwebs |
| Subarachnoid | space filled with CSF and contains blood vessels |
| Pia Mater | tightly bound to the surface of the brain and spinal cord |
| Cerebrum | largest portion of the brain |
| Longitudinal fissure | divides the brain into two cerebral hemisphere |
| Corpus Callosum | arching band of white fibers |
| Cerebral cortex | outer region of cerebrum, its grey matter makes us HUMAN |
| White Matter | Myelinated nerve fibers that form communication pathways in the cerebrum |
| Diencephalon | Thalamus, Hypothalamus, and Pineal gland |
| Thalamus | channels impulses in cortex, discrimination, localization, and interpretation |
| Hypothalamus | homeostasis; regulates many visceral activities |
| Pineal gland | puberty , biological clock |
| Brain Stems three parts | Midbrain, Pons, and Medulla Oblangata |
| Medulla Oblangata 3 Vital centers | Cardiac center, Vasomotor center, Respiratory center |
| Cardiac center | heart rate |
| Vasomotor center | blood pressure |
| Respiratory center | regulates rate, rhythm, and depth of breathing |
| Cerebellum | coordination, posture, and balance the motor area of the brain |
| Ventricles | fluid-filled cavities in the brain |
| Spinal cord | extends from the foramen magnum at base of skull to the first lumbar |
| Ascending tracts | pathways that carry sensory impulses from body parts to the brain |
| PNS divides into | Somatic nervous system and Autonomic nervous system |
| Sensory nerves | afferent fiber |
| Motor nerves | efferent fibers |
| Mixed nerves | both efferent and afferent fibers |
| Cranial nerves | 12 pairs |
| Spinal nerves | 31 pairs |
| Autonomic Nervous System Two parts | Sympathetic division and Parasympathetic division |
| Sympathetic Division | fight-or-flight |
| Parasympathetic Division | ordinary relaxed conditions, brings body back to normal state after emergency |
