THE NERVOUS SYSTEM
CENTRAL NERVOUS SYSTEM
Brain
Encephalum
Diencephalum
Hypothalamus
thirst and hunger
Epithalamus

grey matter
Telencephalum
two hemispheres connected by corpus callosum
left: logical and analytical thinking
right: intuition and creativity
organised in lobes separated by sulci and fissures
Occipital: vision
Frontal: abstract thinking
Parietal: taste
Temporal: smell and hearing

Functions
Carries
motor information from brain to effectors
sensory information from sensory organs to brain
Produces reflex actions without participations of the brain

Bones
Meninges
Arachnoid
Pia matter
Dura
Cerebrospinal fluid
PERIPHERAL NERVOUS SYSTEM
Autonomic nervous system (regulates and coordinates involuntary functions)
Parasympathetic
control's the body's organs to work effectively while resting
Sympathetic
control's body organs to work effectively under stress
Somatic nervous system (motor response)
Spinal nerves
31 pairs
dorsal root and ventral root
Enter and leave the spinal cord
Cranial nerves
12 pairs
motor, sensory and mixed
Enter and leave the brain
control head, upper torax and some internal organs
