What is the structure of the nervous system?
- Central Nervous System
- Peripheral Nervous System
What is the function of the Peripheral Nervous System?
Carries information to and from the central nervous system
What subsystems are in Parasympathetic Nervous System?
- Somatic Nervous System

Vegetative functions
Rest and digest
What are the mains parts of the brain?
- Forebrain
- Midbrain
- Hindbrain
What are the 4 components of the Hindbrain?
- Medulla Oblongata
- Cerebellum
- Reticular Formation
- Pons
What is the Medulla Oblongatta function?
Extention of spinal cord that regulates heartbeat, circulation and respiration.
Describe the cerebellum
Involved in movement, learning and sensory discrimination
Describe Reticular Formation
A network of neurons involved in consciousness and arousal
Describe Pons
Links Medulla Oblongata and Cerebellum with upper part of brain stem
Whats 2 functions are involved in the midbrain?
- Tectum
- Tegmentum
Describe the function of Tectum
Involved in orienting to visual and auditory stimuli
Describe Tegmentum
Involved in movement and arousal
