  1. Hello everyone.
  2. Welcome to a new video.
  3. Today we are discussing about a very important part of
  4. human body.
  5. The brain.
  6. I'm abdulla centric a final year student of archeology and
  7. speech language pathology from Peyser Beauty.
  8. I'll be discussing the physiology part of the human body.
  9. To understand the physiology of the brain.
  10. We have to understand what the brain is.
  11. So what is the brain?
  12. Brain is an important organ of the human body.
  13. It is made of nervous tissue.
  14. The main function of the brain is to command task
  15. evil response like sense, movement and emotions, Language, communication, thinking
  16. and memory.
  17. There are three parts of the human being, the cerebellum,
  18. the cerebellum and the brain stem.
  19. So let's discuss what is cerebrum.
  20. So in the cerebrum it has two parts the left
  21. hemisphere and the right hemisphere.
  22. As you can see in this picture The hemispheres have
  23. several 4s and convulsions.
  24. The the regions between the conversions of art known as
  25. guide and the valley between the guidance and then a
  26. sulky. The poor of salty is Sakas.
  27. The hemispheres are covered with an outer layer made of
  28. gray matter which is known as cerebral cortex, celebra.
  29. So as we have discussed the Brahm let's discuss about
  30. the cerebellum.
  31. So like cerebrum.
  32. It has also two parts here.
  33. It is called the cerebral cortex and there's deep cerebral
  34. nuclear. It is connected to the brain stream by a
  35. structure called a cerebral petting cute.
  36. What is the function of cerebral cerebral um So the
  37. main function of cerebellum is the motor coordination, posture and
  38. balance. So let's talk about the third part of our
  39. brain that is the brain stem.
  40. So in this three main parts of the brain, the
  41. brain stream contains the midbrain pons and medulla.
  42. It is located on the base of the sarah graham
  43. and the spinal cord.
  44. Now we have already gone through the anatomical part of
  45. the brain.
  46. Let's discuss the function of these parts.
  47. Let's discuss about the cerebrum.
  48. So what is the function of cerebrum?
  49. The main function of celeb rams is controlling the and
  50. monitoring, monitor motor and sensory information.
  51. The main function of cerebellum is controlling motor and sensory
  52. information, conscious and unconscious behavior, intelligence and memory.
  53. There are some special functions for the two hemispheres like
  54. the left hemisphere have a special function of controlling speech
  55. and abstract thinking.
  56. That is the ability to think about things that are
  57. not present.
  58. There are also a special function for the right hemisphere.
  59. The function is known as special thinking that is.
  60. It finds the meaning in shape, size, orientation, location and
  61. direction of objects process of Thelma.
  62. So there are lots of cerebrum.
  63. The four lobes of cerebrum are as follows.
  64. The frontal lobe, the parietal lobe, occipital lobe and the
  65. temporal. The functional for uh frontal lobe is mainly executive
  66. functions like discussions, judgment, concentration, attention, emotion response and memory.
  67. The period of loop functions as uh receptor of the
  68. senses of taste and touch.
  69. Test such a sweet sour or salty and touch as
  70. in pain, temperature, oppression, dr peter liu, occipital lobe.
  71. The the occipital lobe is the most protective lobe in
  72. the brain.
  73. It deals with a very important sense the sense of
  74. vision. Like observe, it'll look.
  75. There is an important function played by the temporal lobe
  76. also. So the important functions of temporal lobe are as
  77. hearing, danger and rex, alerts enjoyment, smell, awareness and physical
  78. balances. So these are the overall functions of the cerebrum.
  79. So let's just cut about the cerebellum.
  80. So the main function of cerebellum is to control the
  81. coordination of voluntary movements.
  82. It finds use the precision and accuracy of the modern
  83. movements. It also aids in the attention, language, pleasure response
  84. and regulation of fear.
  85. It also helps in balance and posture.
  86. So the last one was not the list the brainstem,
  87. the brain same acts as a breeze between the cerebrum
  88. and cerebellum to the spinal cord.
  89. It mainly performs the autumn comical function like breathing, temperature,
  90. heart trade, sleeping, cycle, coughing and sneezing, digestion, vomiting and
  91. swallowing. So as we have already gone through the main
  92. parts of the brain as we have already discussed earlier
  93. that since is an important function of the brain.
  94. So let's discuss about the city areas and the modalities.
  95. So what is the sense areas since areas are the
  96. areas of the brain that receive and process sensory information.
  97. The Cortex is composed of three parts the sensory, the
  98. model and the association areas.
  99. The part of the cortex that receives the sensory input
  100. from the telemachus is known as the primary sensory ideas.
  101. There are five modalities of this area.
  102. As you can see in this picture.
  103. Touch smell, hearing taste I said.
  104. These are the five modalities.
  105. So the test or the gas story sensation.
  106. The mastery area is near the first penetration within the
  107. uh post central guides the olfactory or the smell is
  108. located in the ankles found among the ventral surface of
  109. the temporal.
  110. The sense of vision or eyesight is located on the
  111. Calgary in sulka of the optical look.
  112. Likewise touch the some of the some of the sensation
  113. is a perception of activation of the neural receptors in
  114. the skin and the most important sensation is the hearing
  115. sensation. It is the primary auditory cortex is located in
  116. the transfers good idea that impala, as a student of
  117. audiology and speech language pathology, it is important for us
  118. to have knowledge of the sense that how the sense
  119. of hearing functions as we know the hour hearing.
  120. The main part of our hearing sensation is our air
  121. and it is three parts the external air, the middle
  122. ear and the inner area.
  123. The inner her cell are most important for conveying auditory
  124. information to the brain.
  125. About 90%.
  126. About 90% of the affair neurons carry information from the
  127. hair cells, therefore and bipolar neurons that come with auditory
  128. information traveled from the copier to the meddler through the
  129. ponds of the midbrain in the brain stem, finally reaching
  130. to the primary cortex of the temporal lobe like the
  131. sense of uh later sense of herring.
  132. The sense of balance is also important for us.
  133. The sense of balance is also known as the vestibular
  134. system. So this is a picture of the vestibular system
  135. and it is very similar with the auditory system.
  136. It also utilizes the hair cells just like the auditory
  137. system. The five vestibular receptor organs in the inner ear,
  138. helping in the maintaining balance at the cuticle, the sulky
  139. and the three semicircular canals.
  140. As you can see in this picture the uh the
  141. superior Colonel, the posterior Canada and the horizontal Canada.
  142. Look at that.
  143. They make a vestibular labyrinth, the bending of the settlers.
  144. The bending of the santa Rosalia.
  145. In the cuticle, stimulus specific neurons that stimulates the the
  146. bending of the stereo.
  147. The bending of the stereo cilia in the U.
  148. Tickles, stimulus specific neurons that signal the brain that the
  149. head is still dead, allowing the maintenance of balance.
  150. The mystical bank.
  151. The distribute the vestibular glands of the vestibule cock, the
  152. vestibule club, the vestibular branch of the festival cochlear nerve
  153. deals with the balance.
  154. That is all about the physiology of the human brain.
  155. I hope you have enjoyed the video and keep learning
