The Brain

• Parts of the Brain:

  A) Hypothalamus

  B) Pituitary Gland

  C) Medulla

  D) Cranium

  E) Cerebrum

  F) Cerebellum

  G) Spinal

  H) Vertebral

  
• Parts of the Brain:

  • [Cerebrum] Made up of two Hemispheres, which receive Messages from our Sensory Organs, and Controls our VOLUNTARY Actions
  • [Hypothalamus] Keeps Homeostasis, our Temperature and Water Content STABLE
  • [Pituitary Gland] Secretes Hormones into the blood
  • [Cerebellum] Maintains BALANCE and Coordinates pairs of Muscles (like riding a bike)
  • [Medulla] Controls Heartbeat and BREATHING Rate

  A) Medulla

  
• [BRAIN DISEASES]

  Alzheimer's Disease

  • Alzheimer's Disease CAUSES DEMENTIA
  • The Symptoms begin with mild Memory Loss, and leads to LOSS of the ability to carry on a Conversation

  Causes:

  • It is Caused by a Build Up of PROTEINS in Brain Cells, and these proteins are AMYLOID and TAU

  --> The Build up of Amyloid and Tau KILLS Brain Cells

• [BRAIN DISEASES]

  Vascular Dementia

  • Early signs of vascular dementia can include Slowness of Thought, Difficulty with Planning, OR Trouble with Understanding

  Causes:

  • Dementia is caused by DAMAGED BLOOD VESSELS in the Brain

  --> The Blood Vessels become BLOCKED or Leak. This Limits the amount of Oxygen and Nutrients getting to the Brain, causing Brain Cells to DIE

• BRAIN DISEASES:

  Parkinson's Disease

  • The Early Symptoms start with a TREMOR (shaking) in the Hand or Fingers, which gets Worse over time
  • MUSCLE Stiffness can occur, causing their Posture to become BENT OVER

  Causes:

  • Parkinson's is caused by the DEATH of Certain Neurones in the Brain

  These Neurones produce a Neurotransmitter called DOPAMINE

  • A Decrease in these Dopamine Levels causes ABNORMAL Brain Activity, leading to Parkinson's
