5.1: overview – nervous system
▪ Familiarise with the telencephalon, white and grey matter structures, and some of
their functions
▪ Ability to define and locate the diencephalon, mesencephalon, metencephalon,

Nervous system: a complex collection of specialized neural cells (neurons) that are
responsible for transmitting signals between different parts of the body
Two components of the nervous system:
• Central nervous system- bran, spinal cord and nerves
• Peripheral nervous system-sensory neurons and ganglia
,The brain is divided into 3 geographical parts:
▪ Hindbrain
▪ Midbrain
▪ Forebrain
The forebrain can be further subdivided into 2 parts:
▪ Dienecphalon
▪ telenacephalon
Telencephalon consists of:
▪ Cerebral cortex
▪ Hippocampus
▪ Amygdala
▪ Olfactory bulb
▪ Basal ganglia
Cerebral cortex – a term used to describe the outer layer of the cerebral hemisphere or
outermost layer of the brain
The cerebral cortext consists of two ridges:
▪ Sulcus
▪ Gyrus
the cerebrum is formed from 2 cerebral hemispheres within which each
hemisphere is then divided into 4 areas called lobes:
Frontal lobe: invloves personality, behaviour, emotions, speech such as speaking and writing
(brocas area) as well as body movements (motor strip)
Pareital lobe: sense of touch, pain, temperature (sensory strip)
Occipital lobe: vision (colour, light, movement)
Temporal lobe: hearing
