The Nervous System

1. The Nervous System Exodus 31:3 and I have filled him with the Spirit of God, with wisdom, with understanding, with knowledge and with all kinds of skills August16,2011 By: Corren Scott 8th

2. Nervous System • The nervous system is an organ system that is a chain of neurons that transfer information to different parts of the body. • The nervous system has two main parts, the (CNS) central nervous system and the (PNS) peripheral nervous system. This is a picture of the full nervous system

3. CNSCentral Nervous System • The CNS is the second part of the nervous system. • This system consists of the brain and spinal cord. • This system is called the central nervous system because they are the more important organs in the nervous system. This is the CNS. The brain is at the top and the spinal cord is the rest.

4. The Brain • The brain is the first part of the CNS. • There are three parts of the brain: the cerebrum, cerebellum, and the brainstem. • The cerebrum is the largest part of the brain. This controls all of our big thinking and controls all of our conscious actions. • The cerebellum is often called the little cerebrum. This controls all of our complex muscle movements. An example of this is standing without falling over. • The brainstem is the part of the brain that connects the brain to the spinal cord, so that it can convey information to the rest of the body.

5. The brain The parts shown in the picture: cerebrum, cerebellum, brainstem.

6. Lobes of the Cerebrum Frontal Lobe language • The first lobe is the frontal lobe. This lobe controls your :speech, language, thoughts, ideas, processes our emotions and skilled movement speech emotions thoughts Skilledmovement ideas

7. FrontalLobe The purple part of the brain in this picture is the frontal lobe.

8. Lobes of the Cerebrum ParietalLobe • The second lobe is the parietal lobe. This lobe controls all the sensory information, such as pain, pressure, touch and temperature. • tallobe. This lobe controls all the sensory information, such as pain, pressure, touch and temperature. pain pressure touch temperature

9. Parietal Lobe The parietal lobe is the part of the brain that is deep red.

10. Lobes of the Cerebrum Occipital Lobe • The third lobe is the occipital lobe. This is the lobe that processes all visual information. Visual information

11. Occipital Lobe The occipital lobe is the part of the brain that is green.

12. Lobes of the Cerebrum Temporal Lobe • The forth lobe is the temporal lobe. This lobe identifies smells and tones and loudness of sound. It also stores memory. smell

13. Temporal Lobe The temporal lobe is the part of the brain that is indigo(dark blue).

14. Cerebral Challenge Parietallobe Temporal lobe Frontal lobe Occipital lobe

15. Spinal Cord • The spinal cord is made up tracks that are protected by the spinal column. • There are twenty-four nerves that come from the spinal cord. • The first eight nerves that come from the spinal cord are cervical nerves(C1-C8) • Next are the thoracic nerves that cross the chest(T1-T12). • Then are the five lumbar nerves (L1-L5). • After the lumbar nerves are the sacral nerves (S1-S5). • The last nerve is the coccygeal nerve.

16. Did you know?/ Fun Facts • The right side of your brain controls the left side of your body and vise versa for the left side of your brain. • There is extra protection for your brain with what is called cerebrospinal fluid. This fluid helps keep the brain comfortable and in place. • The reflex arc is the way the spinal cord processes information. To process information the spinal cord uses interneurons, sensory neurons, motor neurons and muscles. • Brain size does not determine how smart you are, how many interneuron connections determines that.

17. PNSPeripheral Nervous System • The peripheral nervous system is divided into two parts as well, the (ANS) autonomic nervous system and the (SNS) somatic nervous system. • Peripheral means outside, that why its called the peripheral nervous system, because this nervous system controls the nerves that branch off from the spinal cord. • This system controls sixty-four nerves that are not connected to the spinal cord, thirty-one nerves on each side.

18. SNSSomatic Nervous System • The somatic nervous system is responsible for voluntary movements, which mean movements that we can control. • SNS carries information from your body to your central nervous system(CNS), and then from your CNS to your body. • The information sent to our CNS are messages that we think about. • An excellent example of this is telling your finger to flip the page in a book. You thought about it and then performed it, this is thanks to your somatic nervous system.

19. ANSAutonomic Nervous System • The ANS is the opposite of the SNS it works automatically, because it controls your involuntary movements. • This system controls your “smooth muscles”, such as your stomach churning the food you are trying to digest. • The flight or fight response is initiated by the autonomic nervous system, this is hardwired in your brain. • Your autonomic nervous system sometimes involves other systems, such as your skeletal and muscular system.

20. Neurons • A neuron is the most important cell of the in the nervous system. Neurons form together to make nerves. • There are many different types of neurons. • Sensory neurons take information to the brain. • Motor neurons carry back information to your body.

21. Bonus Slide How Alzheimer’s disease affects your brain…… “Alzheimer’s disease leads to nerve cell death and tissue loss throughout the brain. Over time, the brain shrinks dramatically, affecting nearly all its functions.” - www.alz.org/brain

22. God said to Solomon, “Since this is your heart’s desire and you have not asked for wealth, possessions or honor, nor for the death of your enemies, and since you have not asked for a long life but for wisdom and knowledge to govern my people over whom I have made you king – 2 Chronicles 1:11 the END Hope You Enjoyed!
