1. Do Now—11.16.15 TRUE OR FALSE A person can be blind without having a damaged eye. Behaviors can be made automatic. Our senses (hearing, olfaction, taste, sight, touch) do not work in isolation. Reflexes are different from responses. There are different stages of sleep. The left side of your brain controls the right side of your body. Neurons are lost (die) before you are born Certain parts of your brain are responsible for certain functions. Turn in your Do Now Reflections to the front

3. The Nervous System

4. Objectives SWBAT describe the anatomy and physiology of the nervous system.

5. Nervous System Which survival need and life function is fulfilled by the nervous system?

6. Nervous System Which survival need and life function is fulfilled by the nervous system? Survival need = heat/temperature Life function = respond and react

7. Homeostasis Homeostasis is regulated and controlled by the nervous system (rapid response) and the endocrine (slower response) system.

8. Sensation & Perception Sensation is experiencing stimuli passively. Perception is interpreting stimuli actively.

9. Sensation & Perception Sensation is experiencing stimuli. Perception is interpreting stimuli. Sensations can be defined as the passive process of bringing information from the outside world into the body and to the brain. The process is passive in the sense that we do not have to be consciously engaging in a "sensing" process.Perceptio n can be defined as the active process of selecting, organizing, and interpreting the information brought to the brain by the senses. A) HOW THEY WORK TOGETHER: 1) Sensation occurs: a) sensory organs absorb energy from a physical stimulus in the environment. b) sensory receptors convert this energy into neural impulses and send them to the brain. 2) Perception follows: a) the brain organizes the information and translates it into something meaningful

10. Which Obama is more handsome?

19. Thatcher Effect Thatcher Effect showed that we examine images holistically.

20. Three functions of the nervous system: sensory input, integration and motor output. Nervous System Functions

21. Sensory input: we use sensory receptors to monitor the stimuli in and out of our body. Nervous System Functions

22. Sensory input: we use sensory receptors to monitor the stimuli in and out of our body. Integration: we process and interpret stimuli and determine the appropriate response necessary. Nervous System Functions

23. Sensory input: we use sensory receptors to monitor the stimuli in and out of our body. Integration: we process and interpret stimuli and determine the appropriate response necessary. Motor output: we activate muscle contraction. Nervous System Functions

24. Nervous System Divisions CNS PNS Sensory (afferent) Motor (efferent) Nervous System Somatic (voluntary) Autonomic (involuntary) SympatheticParasympathetic

25. Central Nervous System is made of the brain and spinal cord. The CNS interprets stimuli and issues instructions to the body using the PNS. Nervous System Anatomy & Physiology

26. The Peripheral Nervous System is made of the spinal nerves and cranial nerves. The PNS is how signals are sent to and from the body. Nervous System Anatomy & Physiology

27. The PNS is made of the spinal nerves and cranial nerves. The PNS is how signals are sent to and from the body. The sensory division carries impulses to the CNS (afferent) and the motor carries impulses from the CNS (efferent). Nervous System Anatomy & Physiology

28. The parasympathetic is the resting system and the sympathetic is the active system of the autonomic (automatic) Nervous System Anatomy & Physiology

29. The parasympathetic is the resting system and the sympathetic is the active system. The parasympathetic division is the D division (digesting, defecation, and diuresis) while the sympathetic is the E division (exercise, excitement, emergency and embarrassment). Nervous System Anatomy & Physiology

30. When you are digesting food which division of the nervous system are you using? Exit Slip

31. When you are digesting food which division of the nervous system are you using? Parasympathetic Division Exit Slip

32. Phineas Gage (1823-1860) Phineas Gage was a hard-working, efficient, respectable man.

33. Phineas Gage (1823-1860)

36. The rod went through Gage’s left frontal lobe.

37. Phineas Gage (1823-1860)

38. After the accident Phineas Gage was angry and vulgar. He was fired from his job and loss many of his friends and made his living as a traveling medical miracle.
