Slide 1-

1 Baseball The Nervous System
Slide 2-

2 What are the two major divisions of the nervous system? Answer: Central & Peripheral What cells are the structural & functional unit of the nervous system? Answer: Neurons Questions:
Slide 3-

3 The central nervous system is composed of what organs? Answer: Brain & Spinal Cord What composes the peripheral nervous system? Answer: Spinal and Cranial Nerves Questions:
Slide 4-

4 What are the specialized cells that aid neurons (by producing myelin & helping communication)? Answer: Neuroglia What part of the neuron is the “receptive surface”? Answer: Dendrite Questions:
Slide 5-

5 Where is the nucleus located in the neuron? Answer: Cell Body Match the neuroglia with it’s function. Questions: Microglia Oligodendrocyte Astrocyte Ependymal Phagocytosis Support Form myelin like Schwann cells Form lining in ventricles

6 Identify the area marked with an arrow in the picture to the right. Answer: Corpus callosum Questions:
Slide 7-

7 Identify the area of the brain stem marked with an arrow in the picture to the right. Answer: Pons Questions:
Slide 8-

8 Identify the area of the brain marked with an arrow in the picture to the right. Answer: Cerebellum Questions:
Slide 9-

9 Questions: 1 2 3 4 Identify the 4 lobes of the brain. Answer: 1. Occiptal 2. Parietal 3. Frontal 4. Temporal
Slide 10-

10 What is the function of the corpus callosum? Answer: connects right & left hemispheres of brain Questions:
Slide 11-

11 Questions: 1 2 3 4 Name the lobe & match the function: Hearing Vision Concentration Understanding speech Temporal:hearing Parietal: understanding speech Frontal: Occiptal: concentration vision
Slide 12-

12 Questions: What part of neuron is indicated by the arrow? Answer: Dendrite What is the function of this portion of the neuron? Answer: main receptive surface for electrical impulses
Slide 13-

13 Questions: What part of neuron is indicated by the arrow? Answer: Axon What is the function of this fiber? Answer: it conducts impulses away from the cell body
Slide 14-

14 What do the tiny circles in the space represent? Neurotransmitter Questions: What is the name of the space between the 2 neurons? Answer: Synapse
Slide 15-

15 Questions: What part of an action potential is illustrated by the red line? Answer: Depolarization
Slide 16-

16 Questions: What is the name of the gaps between Schwann cells? Answer: Nodes of Ranvier Grey Matter or White Matter, which is myelinated? Answer: White Matter
Slide 17-

17 Questions: Name that structure Answer: Pituitary Gland
Slide 18-

18 Which area is the postsynapic neuron, which is presynapic? Questions: What structure is located at the arrow? Answer: Mitochondrion
Slide 19-

19 Questions: What part of an action potential is illustrated by the red line? Answer: Repolarization
Slide 20-

20 What are the layers of the meninges from innermost to outermost. Answer: Pia, Arachnoid, Dura Questions: What area forms cerebrospinal fluid? Answer: Choroid Plexus
Slide 21-

21 Between which layers of the meninges is CSF found? Answer: Arachnoid and Pia Which has a lower conductivity for impulses, grey or white matter? Answer: Grey Questions:
Slide 22-

22 Name the type of fast conduction when impulses jump from node to node (Ranvier) Answer: Saltatory Where is the greatest concentration of Na+, inside or outside axon? Answer: Outside Questions:
Slide 23-

23 Questions: What is happening during this phase? Answer: Na+ rushes in
Slide 24-

24 Questions: What is happening during this part of the ap? Answer: K+ rushing out
