GETTING IN TOUCH WITH YOUR BRAIN
• The human brain weighs about 1.5kg in adults• It has the consistency of firm jelly and is covered by
strong, plastic like membranes• There is a small gap between the brain and the skull
which is filled with fluid• The fluid provide a cushion against knocks to the head,
protecting the brain from damage unless the knock is quite hard

THE CEREBRUM
• It occupies more than 80% of the brain
• It is here that the higher intellectual functions of humans take place
• It controls your conscious thoughts and voluntary movement of every body part, and sensory messages from all body parts
• The cerebrum is made up of two parts called the right and left cerebral hemispheres

RIGHT HEMISPHERE
• Controls the left side of the body
• This is where visual special skills are coordinated, dancing and gymnastics are coordinated
• Memory is stored in auditory, visual and special modalities

LEFT HEMISPHERE
• Controls the right side of the body
• Systematic, logical interpretation of information; interpretation and production of symbolic information
• Language, mathematics, abstraction and reasoning
• Memory stored in a language format

THE CEREBRUM
•There are 4 lobes:•Frontal•Parietal•Occipital•Temporal
![Page 8: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/8.jpg)
FRONTAL LOBE
• Responsible for conscious thought, cognition and memory• Controls the ability to concentrate, higher intellectual reasoning, aggression, judgement and inhibition• Plays a role in personality and emotional traits
![Page 9: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/9.jpg)
TEMPORAL LOBE
•Receives and evaluates input for smell and hearing and plays an important role in memory
![Page 10: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/10.jpg)
PARIETAL LOBE
•Responsible for processing of sensory input and sensory discrimination•Plays a part in orientation
![Page 11: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/11.jpg)
OCCIPITAL LOBE
•Primary visual reception and interpretation area

CEREBELLUM
• Is like a smaller version of the cerebrum and is responsible for movement, balance and coordination
![Page 14: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/14.jpg)
THE BRAINSTEM
• Sits mostly inside the brain • At its base it becomes the spinal cord• The brainstem is made up the three major parts: the medulla, the pons and the midbrain
![Page 15: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/15.jpg)

THE MEDULLA
• Its at the bottom of the brainstem and automatic functions, like respiration and digestive system activities
![Page 17: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/17.jpg)
PONS
•Assists in some automatic functions, like breathing, and also controls sleep and arousal
![Page 18: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/18.jpg)
MIDBRAIN
•Contains areas that receive and process sensory information, such as movement and vision
![Page 19: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/19.jpg)
RETICULAR FORMATION
• Controls sleep and wake cycles•Damage to this area may result in a coma• Plays a role in alertness, fatigue, and motivation to perform various activities
![Page 20: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/20.jpg)
HYPOTHALAMUS
•Maintains constant heart rate, body temperature and sleep pattern• It is also involved in hormone production by control of the pituitary gland
![Page 21: THE BRAIN. GETTING IN TOUCH WITH YOUR BRAIN The human brain weighs about 1.5kg in adults It has the consistency of firm jelly and is covered by strong,](https://reader035.vdocuments.mx/reader035/viewer/2022062519/5697c0271a28abf838cd6289/html5/thumbnails/21.jpg)
THALAMUS
•Process and carries messages for sensory information, such as information sent from the ears and skin to the cortex
