3 It’s the major control unit of the body. It controls your thinking, memory, and you learning. It detects changes in the body. Controls all muscle activities in body.

4 Central Nervous System Peripheral Nervous System Somatic Nervous System Autonomic Nervous System Sympathetic Nervous System Parasympathetic Nervous System

5

6 Informs body of about itself and the world around it It is essentially like the biological highway Processes the information received by the peripheral nervous system

7

8 Resides and extends outside central nervous system Main function is to connect Central Nervous System to limbs and organs Include special senses such as taste, smell, sight, hearing, and balance.

9

10 Part of Peripheral Nervous System Associated with voluntary control of body movements Includes all neurons connected with skeletal muscles

11

12 Also known as the Visceral Nervous System Maintains homeostasis Performed without conscious control Divided into Sympathetic and Parasympathetic Nervous System

13

14 Part of Autonomic Nervous System Located to the Sympathetic Chain that connects to skin, blood vessels, and organs in the body cavity Activated flight or fight response

15

16 A division of the Autonomic Nervous System Sends fibers to the following: cardiac muscle, smooth muscle, or glandular tissue Can be summarized as “rest” and “response”

17

18 Bells Palsy A form of Neuritis that involves paralysis of the facial nerve causing weakness of the muscles of one side of the face and an inability to close the eye Paralysis of the facial nerve; weakness of the muscles of one side of the face may result in inability to close the eye In some cases the patient's hearing may also be affected in such a way that sounds seem to him/her to be abnormally loud. Loss of taste sensation may also occur

19 A non progressive disorder of movement resulting from damage to the brain before, during, or immediately after birth The most common disability is a spastic paralysis. Sensation is often affected, leading to a lack of balance, and intelligence, posture and speech are frequently impaired. Contractures of the limbs may cause fixed abnormalities Other associated features include epilepsy, visual impairment, squint, reduced hearing, and behavioral problems

20 A progressive degenerative disease of the motor system occurring in middle age and causing muscle weakness and wasting Motor Neuron disease primarily affects the cells of the anterior horn of the spinal cord, the motor nuclei in the brainstem, and the corticospinal fibers.

21 Slows down brain functions Increases anxiety May paralyze the medulla oblongata

22 Can cause loss of messages from brain to heart or lung instantly Loss of brain cells Alters the brain into thinking it needs the drugs
