Q

What are the functional divisions of the NS?

A

PNS
- afferent (sensory)
- receptors send info to CNS
PNS
- efferent (motor)
- Somatic (SNS) (skeletal muscles)
- Autonomic (ANS)
- Sympathetic (fight or flight)
- Parasympathetic (rest and Digest)

Q

What is the organization of the NS?

A
  • Receptors (sensory, visceral, somatic)
  • Sensory info in afferent
  • Process data + motor commands
  • Motor commands in efferent
    • SNS - skeletal muscles
    • ANS - parasympathetic, sympathetic

Q

What is the purpose of the Cerebrum?

A
  • makes you, you
  • difference between humans and animals
  • conscious thought processes, intellectual functions
  • memory storage and processing
  • conscious and unconscious regulation of skeletal muscles

Q

What is the purpose of the Cerebellum?

A
  • motor control patterns
  • coordinates somatic motor patterns
  • adjusts output of other somatic motor centres in brain and spinal cord
17
Q

What is the purpose of the Diencephalon?

A
  • receives and distributes sensory info
  • hormonal response
    Thalamus
  • Relay and processing centres for sensory information
  • all senses except smell
    Hypothalamus
  • enters controlling emotions, autonomic functions and hormone production
  • contains pituitary gland
18
Q

What is the purpose of the Brainstem? (Medulla Oblongata, Pons, Midbrain)

A
  • ancient part
  • keeps us alive
  • autonomic
19
Q

What is the purpose of the Medulla Oblongata?

A
  • relays sensory info to thalamus and portions of brainstem
  • autonomic enters for regulation of visceral function (cardiovascular, respiratory, digestive)
  • connects to spinal cord at foramen magnum
20
Q

What is the purpose of the Pons?

A
  • relays sensory info to cerebrum and thalamus
  • subconscious somatic and visceral motor centres - breathing
21
Q

What is the purpose of the Midbrain?

A
  • processing of visual and auditory data
  • generation of reflexive somatic motor responses ex. vomiting
  • maintenance of consciousness
    Superior Colliculus - visual processing
    Inferior Colliculus - auditory processing
22
Q

What are the ventricles of the brain?

A
  • fluid filled cavities in brain
  • plays role in cerebral spinal fluid
  • 2 lateral ventricles, 3rd ventricle, 4th ventricle
23
Q

What are the parts in protection of the brain? (2)

A

Physical, Biochemical

24
Q

What are the physical factors in brain protection? (3)

A

Bones of cranium, Meninges, Cerebrospinal fluid

25
Q

What are the biochemical factors in brain protection? (1)

A

Blood brain barrier

26
Q

Where are the major sulci? (3)

A

Lateral - behind ear
Central - between lateral
Longitudinal Fissure - longitudinal

27
Q

What is Insula?

A
  • Inside lateral sulcus
  • 5th lobe
  • Implicated in seizures
