Brain anatomy

Question 1

• judgement, personality, goal-orientated/motivation, attention, and some of your long-term memory
• Precentral gyrus: Primary motor, basic of controlling motor
• Broca’s: language production (forming the word/motor)

Answer 1

• Frontal lobe: (forebrain)

Question 2

• Postcentral gyrus: Controls sensory, putting sensory together (taste, smell, vision), recognize objects by touch (tactile)
• communication between sensory motor area. Store, analyze, and interpret.

Answer 2

• Parietal Lobe (forebrain)

Question 3

• Vision
• visual motor area (program & carry out eye movement),

Answer 3

• Occipital Lobe (forebrain)

Question 4

• Hearing & short-term memory
• auditory, smell, memory consolidation
• Wernicke: putting language together

Answer 4

• Temporal Lobe (forebrain)

Question 5

• Balance, muscle posture

Answer 5

• Cerebellum (Hindbrain)

Question 6

• Tracks

Answer 6

• Pons (Hindbrain)

Question 7

• Vagus nerve (X): HR, GI rate, RR (C1-C2 snapped when hanging)

Answer 7

• Medulla oblongata (Hindbrain)

Question 8

• “4Fs”, emotion (positive & negative), feeding, behaviors, sense of small, biological rhythms

Answer 8

Limbic System:

Question 9

Substantia Nigra:

Answer 9

• Midbrain
  
  • Substantia Nigra: (looks like black substance) produces dopamine > norepi
  • “feeling dop in nigra park” > Parkinson’s

Question 10

Dementia – Alzheimer’s, Huntington’s, MS

What area of the brain?

Answer 10

Forebrain

Question 11

Forebrain sections

Answer 11

• Forebrain (Dementia – Alzheimer’s, Huntington’s, MS)
  
  • Sections:
    
    • Frontal lobe, Occipital, temporal, Parietal lobes
    • Hypothalamus: emotion portion, environmental control
    • Pituitary
    • Limbic System: “4Fs”, emotion (positive & negative), feeding, behaviors, sense of small, biological rhythms

Question 12

• Meninges 3 layers and 3 spaces
• CSF: location, production and drainage

Answer 12

• Meninges:
  
  • Dura Mater: tough outer lining
  • Arachnoid: spinder web)
  • Pia Mater – “pie shell around the brain”
• Epidural space: on top of dura mater
• Subdural space/: imaginary space between dura mater and arachnoid mater
• Subarachnoid space: (between arachnoid & pia mater) CSF
  
  • CSF: choroid plexus (production) & arachnoid villi (drains CSF into venous blood)
  • lumbar puncture
