Not feeling pain is a good thing.. Most people can get along just fine with out senses.. You can control your nervous system.. The Nervous System Good Morning… Bell Ringer #1: Reflect back over winter break . Bell Ringer #2 Review your notes from last class. Answer the following question using those notes: How did your nervous system help you conduct the activity you did in the computer lab (red light/green light activity)? The Nervous System Central Nervous System Peripheral Nervous System Procedure A starting person will be chosen and will be given an object. Once the teacher gives the signal, the start person will pass the object to their right.

Peripheral Nervous System . (PNS) – includes nerves extending from . brain and . spinal . cord . is the main component of the two parts of the . nervous system. ; the . brain. and . spinal cord. of the . central nervous system. (CNS), and the branching peripheral nerves of the . peripheral nervous system. (CNS) AND THE PERIPHERAL NERVOUS SYSTEM (PNS) Learning objectives: The nervous system in humans is a complex integration of organs like brain, spinal cord and sensory organs along with nerves. N Figure 1. Nervous System Hierarchy Characteristics of the Central Nervous System The most fundamental way of categorizing groups of neurons that make up the central nervous system is as nuclei and 85 to 180 billion neurons in the human brain?! How does anything get done?. CENTRAL NERVOUS SYSTEM. Brain and spinal cord.. PERIPHERAL NERVOUS SYSTEM (PNS). Def. : all nerves that lie outside the brain and spinal cord. 1. . Afferent. 1. . a brain area critical to learning to recognize threatening situations. 2. . amygdala. 2. . toward the nose. 3. . anterior . 3. . One of three meninges that surround and protect the spinal cord and the brain.
