1

What is the structure of the nervous system?

  • Central Nervous System
  • Peripheral Nervous System

2

What is the function of the Peripheral Nervous System?

Carries information to and from the central nervous system

3

What subsystems are in Parasympathetic Nervous System?

  • Somatic Nervous System 
  • Autonomic Nervous system (Sympathetic, Parasympathetic)

4

Describe the structure & function of the spinal cord

The spinal cord has dorsal and ventral roots.

That carry sensory and motor signals to and from the spinal cord

5

What is the Sympathetic Nervous System?

Fight or Flight

6

What is the function of the Parasympathetic Nervous System?

Vegetative functions 

Rest and digest

7

What are the mains parts of the brain?

  • Forebrain
  • Midbrain
  • Hindbrain

8

What are the 4 components of the Hindbrain?

  1. Medulla Oblongata
  2. Cerebellum
  3. Reticular Formation
  4. Pons

9

What is the Medulla Oblongatta function?

Extention of spinal cord that regulates heartbeat, circulation and respiration.

10

Describe the cerebellum

Involved in movement, learning and sensory discrimination

11

Describe Reticular Formation

A network of neurons involved in consciousness and arousal

12

Describe Pons

Links Medulla Oblongata and Cerebellum with upper part of brain stem

13

Whats 2 functions are involved in the midbrain?

  1. Tectum
  2. Tegmentum

14

Describe the function of Tectum

Involved in orienting to visual and auditory stimuli

15

Describe Tegmentum

Involved in movement and arousal

16

What 6 subcatergoies are involved in the forebrain?

  1. Septal area
  2. Amygdala
  3. Hippocampus
  4. Hypothalamus
  5. Thalamus
  6. Basal Ganglia

17

Describe Septal area

Involved in pleasure, relief from pain, emotionally-significant learning

18

Describe the Amygdala

Involved in aggression and fear

19

Describe Hippocampus

Involved in the storage of new memories

20

Describe Hypothalamus

Helps regulate eating, sleeping, sexual activity

21

Describe Thalamus

Process incoming sensory information --> transmits it to higher brain areas

22

Describe Basal Ganglia

Involved in the control of movement (autonomic)

23

Describe the functions of the cerebral cortex

  • Makes symbolic thinking possible
  • Understanding
  • Personality

24

What are the 6 lobes of the cerebral cortex?

  1. Frontal lobe
  2. Parietal lobe
  3. Occipital lobe
  4. Cerebellum
  5. Temporal lobe
  6. Limbic 

25

Describe Frontal Lobe

  • Abstract thinking
  • Planning
  • Social skills

26

Describe Temporal lobe

Important for hearing, language, recognising object, memory

27

Describe Parietal lobe

  • Sensation
  • Perception of movement
  • Location of objects in space

28

Describe Occipital lobes

Vision and visual recognition

29

Name a mild language disorder

Broca's Aphasia.

30

Describe Broca's Aphasia

Comprehension is only mildly impaired, work fluency is deficient
