Nervous System Tea Party Name____________________ Date_______ 1. What are the structures found in the Central nervous system (CNS)? It is composed of the brain and spinal cord. 2. What is the Somatic nervous system? Subdivision of the PNS that controls voluntary activities such as the activation of skeletal muscles. 3. What is the Peripheral nervous system (PNS)? Nervous system subdivision that is composed of the cranial nerves and spinal nerves. 4. What is the Autonomic nervous system? Subdivision of the PNS that regulates the activity of the cardiac muscle, smooth muscle, and glands. It controls body activities automatically. 5. What are Neurons? Cells that transmit electrical message from one area of the body to another area. 6. What is an Axon? End of neuron that releases neurotransmitters away from the cell body. 7. What is a Dendrite? End of neuron that conducts electrical currents toward the cell body. 8. What is Myelin? Fatty material that covers long nerve fibers, protecting and insulating the fibers, as well as Increasing the speed of impulse transmission. 9. What is the Cell body? Location of the nucleus in a neuron. 10. What are Schwann cells? (Honors) Specialized cells that myelinate the axons of neurons found in the PNS. (Honors) 11. What is a Synapse? Junction or point of close contact between neurons. 12. What are Nodes of Ranvier? Spaces in the myelin sheath between schwann cells. 13. What are Ganglia? (Honors) Collection(clumps) of nerve cell bodies found outside the CNS. (Honors) 14. What is a motor neuron? Neuron that conducts impulses away from the CNS to muscles and glands. 15. What are Stimuli? Changes, occurring within or outside the body, that cause some kind of response 16. What is a sensory neuron? Neuron that conducts impulses toward the CNS from the receptors. 17. What are Neurotransmitters? Chemicals released by neurons that stimulate other neurons, muscles, or glands. 18. What is Depolarization? State in which the polarity of the neuron is reversed as sodium ions rush into the neuron. 19. What is Repolarization? Period during which potassium ions move out of the neuron resulting in a return of the polarization to its resting state. 20. What are Potassium ions? (Honors) The chief positive ion found inside a neuron during its resting state(Honors) 21. What is Sodium potassium pump? A membrane protein that uses ATP to move sodium ions out of the cell and potassium ions back into the cell; completely restores the resting conditions of the neuron. 22. What is the function of the Hypothalamus? (Honors) It regulates body temperature, sleep and emotions. (Honors) 23. What is the function of the Cerebellum? I regulates balance and coordination of skeletal muscle movements. 24. What is the function of the Thalamus? (Honors) It is an important relay station for the brain 25. What is the function of the Medulla oblongata? Contains centers which regulate blood pressure, heart rate, breathing, swallowing, and vomiting, 26. What is a Concussion? Occurs when the brain injury is slight. Although patient may be dizzy or briefly lose consciousness, the damage is not permanent. 27. What is a Stroke? Occurs when blood circulation to the brain area is blocked, as by a blood clot or a ruptured blood vessel and vital brain tissue dies. 28. What is Alzheimers disease? (Honors) Progressive degeneration of the brain that ultimately results in dementia. (Honors) 29. What is Multiple sclerosis? Autoimmune disorder that attacks the proteins in the myelin sheath causing a short circuit of the nervous system resulting in person being unable to control muscle movement. 30. What is Sodium? (Honors) Chief positive ion found outside of the neuron during its resting state. (Honors) 31. What is the Cerebellum? Large cauliflower-like structure that projects dorsally from under the cerebrum. Provides precise timing for skeletal muscle activity and controls balance and equilibrium. 32. What are the Meninges? Consists of three protective tissues that surround the CNS: the dura mata, arachnoid mater, and the pia mater. 33. What is Meningitis? Inflammation of the meninges posing a serious threat if the bacteria or virus spreads to the CNS. 34. What is Cerebrospinal Fluid (CSF)? Forms a watery cushion that protects fragile nervous tissue from blows and other trauma. 35. What is the Spinal Cord? A large bundle of nerves connected to the brain that is a reflex center. 36. What is the Parasympathetic Division of the Nervous System? Part of the autonomic nervous system that allows us to unwind and conserve energy. 37. What is the Sympathetic Division of the Nervous System? Part of the autonomic nervous system that mobilizes the body during extreme situations. (fear, exercise, or rage) 38. What does the term Fight or Flight mean? Phrase given to instinctive response to danger where our heart rate, blood pressure, blood glucose levels, and oxygen intake from lungs increase to give one more energy for a response. Controlled by the sympathetic division. 39. What is Cerebral Palsy? Birth defect often due to a temporary lack of oxygen that causes brain damage and results in a poorly controlled voluntary muscles, seizures, mental retardation, and/or impaired hearing and eyesight. 40. What is Negative feedback? A mechanism for self-regulation, as the concentration of a particular chemical increases it causes the release of that chemical to decrease and vica-versa 41. What is an endocrine gland? A gland that secretes
