   Dendritic tip of a nerve receives electronic impulse from    muscular tissue present in sense organs
   This impulse travels from the dendrite to the cell body,    and then along the axon to its end.

  16. 16.  Dendritic tip of a nerve receives electronic impulse from muscular tissue present in sense organs
  17. 17.  This impulse travels from the dendrite to the cell body, and then along the axon to its end.
  18. 18.  At the end, the electrical impulse gets converted into a chemical signal for onward transmission. Synapse
  19. 19.  A similar synapse finally allows delivery of such impulses from neurons to other cells, such as muscles cells or gland Synapse

  24. 24.  ‘Reflex’ is a word we use very commonly when we talk about some sudden action, which does not involve thinking in response to something in the environment.
  25. 25.  But, you could think consciously about the pain and the possibility of getting burnt, and therefore move your hand.
  26. 26. BrainSensory Motor nerves nervesSensory organs Motor organs
  27. 27.  The process of detecting the signal and responding to it might be completed quickly, known as reflex arc.
  28. 28.  Session is detected at that place only and responded very fast by motor organs. Although the information input also goes to the brain.This is the role of spinal cord.
  29. 29.  ‘Reflex’ is a word we use very commonly when we talk about some sudden action in response to something in the environment. Brain receives messages from sensory organs & gives instruction to our motor organs to act accordingly Reflex arcs are formed in the spinal cord at the junction between sensory and motor nerves

  45. 45.  Cerebrum receives sensory impulses from various receptors and interprets data by putting together all sensory impulses and stored information in brain. A decision is made about how to respond and the information is passed on to the motor areas which control the movement of voluntary muscles.
  46. 46.  The midbrain controls many important functions such as the visual and auditory systems as well as eye movement.
  47. 47.  Involuntary actions are controlled by the medulla, like BP, Heart beat. The pons connects the medulla to the cerebellum and helps coordinate movement on each side of the body. The Cerebellum is responsible for precision of voluntary actions and maintaining the posture and balance of the body.
  48. 48.  The fore-brain is the main thinking part of the brain & controls voluntary actions. The mid-brain is the smallest part of brain & controls many involuntary actions. The hindbrain is the structure that connects the spinal cord to the brain control involuntary actions
  49. 49.  Read up to page no 118 (NCERT) Draw the diagram of human brain and identify its parts and practice it at least 2 more times.

  51. 51.  Muscle cells have special proteins that change both their shape and their arrangement in the cell in response to nervous electrical impulses. When this happens, new arrangements of these proteins give the muscle cells a shorter form.
  52. 52.  The brain is protected by Skull and Spinal cord is protected by Back bone (Spine). Muscle cells will move by changing their shape when they receive motor impulse send by brain.

  57. 57. “How does the plant detectthe touch, and how do theleaves move in response?”
  58. 58.  But there is no nervous tissue, nor any muscle tissue in plants for the conduction of information.
  59. 59.  Plant cells change shape by changing the amount of water in them, resulting in swelling or shrinking, and therefore in changing shapes.
  60. 60.  Plants show two different types of movement 1. Independent of growth. 2. Dependent on growth Sensitive plants actually move its leaves in response to touch The plants also use electrical-chemical means to convey this information from cell to cell Some cells must change shape in order for movement to happen.

  107. 107.  When a person becomes angryAdrenaline adrenaline is secreted into the blood. It helps the body to adjust to sudden stress. As a result,  Adrenaline causes the heart to beat faster, result in supply of O2 to the body muscles increases.  Small arteries constrict which increases the blood pressure. This diverts the blood to our skeletal muscles. C9H13NO3
