Nervous system

• Meninges structures:

  • Pia mater- outer
  • Arachnoid- middle
  • Dura mater - outer
• Function of meninges? Protection
• List the lobes of the cerebrumlobes

  
  

  frontal

  parietal

  temporal

  occipital
• What structure is the connection between hemispheres?

  Corpus callosum
• What structure in the cerebrum is filled with cerebral-spinal fluid?

  Ventricle
• What structure in the cerebrum increases surface area?

  Gyri and sulci
• What are the two types of matter found in the cerebrum?

  White

  Grey
• What is in this image? Cerebellum

  
• What structure of the brain is this? Cerebrum

  
• Which part of the nervous system co-ordinates voluntary movement? Cerebellum
• Which part of the nervous system is responsible for muscle tone? Cerebellum
• What part of the nervous system is responsible for posture and balance?

  Cerebellum
• Where is the medulla oblongata?

  Brainstem
• What is the lower section of the brain stem before exiting the foramen magnum?

  Medulla oblongata
• Brainstem functions:

  • pathway to and from brain
  • breathing and heartbeat
  • less important reflexes like sneezing or coughing
• What part of the nervous system is in this image?

  Spinal cord

  
• Spinal cord function:

  • pathway for impulses
  • intergrative reflexes
  • primitive reflexes
• Pathway of a reflex:

  1. Stimulus
  2. Sensory neuron
  3. Dorsal Root
  4. Grey matter
  5. Interneuron
  6. Ventral root
  7. Motor Neuron
  8. Effector

  
• Multiple Sclerosis:

  • Autoimmune disease
  • genetically inherited
  • environmental linked
  • loss of myelin sheath surrounding neurons
  • can't conduct electrical impulse from neuron to neuron
  • affect 20 - 40 year olds
• Alzheimers symptoms:

  • decline in memory
  • dementia
  • loss of motor functions (late stage)
• Multiple sclerosis symptoms:

  • fatigue
  • vision problems
  • muscle spams
• What type of therapy can slow down progression of Alzheimers?

  Immunotherapy
• What kind of therapy can be helpful for multiple sclerosis?

  Physical therapy
• Which part of the nervous system are the brain and spinal cord part of?

  Central
• What part of the nervous system are cranial nerves and spinal nerves associated with?

  Peripheral
• What part of the nervous system are voluntary movement and skeletal muscles associated with?

  Somatic
• What part of the nervous system is responsible for maintaining homeostasis Involuntary movement?

  Autonomic
• Which nervous system is responsible for 'rest and digest'?

  Parasympathetic
• Which nervous system is responsible for fight and flight?

  Sympathetic
• Give the function of the ventricle in the brain.

  Filled with cerebral-spinal fluid for cushioning.
• Name the four lobes of the brain.

  1. frontal
  2. parietal
  3. temporal
  4. occipital
• Give the THREE functions of the cerebellum.

  1.Co-ordinates movement

  2. Provide muscle tone

  3. Posture and balance
• Give THREE functions of the medulla oblongata.


  1. pathway to brain
  2. breathing and heartbeat
  3. less important reflexes
