The document discusses the main parts and functions of the human brain. It describes the four main sections - cerebrum, cerebellum, diencephalon, and brain stem - and explains what each controls. It also discusses brain cavities containing cerebrospinal fluid, brain tumors, dementia like Alzheimer's disease, and some relevant medical terminology.
3. What is a brain?
Part of the Nervous System
Coordinates most of the bodies activities
One of the largest organs in the body
Center of all though, memory, judgment, emotions
Each part of the brain is responsible for controlling
different body functions

4. Four Main Sections of the Brain
Cerebrum
Cerebellum
Diencephalon
Brain Stem
June 2012 Biology 120: Medical Terminology 4
5. Cerebrum
Largest section of the brain
Located in upper section
Processes thoughts
Judgments
Memory
Divided into left and right halves
Cerebral hemisphere
4 lobes in each hemisphere
1. Frontal Lobe: controls motor function, personality, speech
2. Parietal Lobe: explains language, analyzes nerve impulses
3. Occipital Lobe: Vision
4. Temporal Lobe: Hearing, smell
June 2012 Biology 120: Medical Terminology 5
6. Cerebellum
2nd largest section of the brain
Coordinates body movement
Maintains equilibrium
Maintains Balance
June 2012 Biology 120: Medical Terminology 6
7. Diencephalon
Located bellow the cerebrum
Thalamus
Composed of gray matter
Center for transmitting impulses from eyes, ears and skin to
cerebrum
Controls pain
Hypothalamus
Controls systems
Autonomic nervous system
Cardiovascular system
Digestive system
Release hormones from pituitary gland
June 2012 Biology 120: Medical Terminology 7
8. Brain Stem
3 components
Midbrain
Connects brain impulses and spinal cord
Pons
Connects cerebellum and brain
Medulla oblongata
Connects brain to spinal cord
Controls respiration, heart rate, temperature and
blood pressure
June 2012 Biology 120: Medical Terminology 8
9. Brain Cavities
Four cavities known as ventricles
Ventricles contains Cerebrospinal fluid
A protection fluid that prevents shock or movement to brain
and spinal cord
Locations
Right hemisphere
Left hemisphere
Thalamus
Front Cerebellum
June 2012 Biology 120: Medical Terminology 9
10. Brain Tumor
What is a Brain Tumor?
An intracranial mass,
Either benign or malignant
Benign Tumor
Can be fatal; causes pressure on normal brain tissue
MalignantTumor
Cancerous
Generally progressive and recurring
June 2012 Biology 120: Medical Terminology 10
11. Dementia
Progressive loss of cognitive ability
Impairment on performing daily activities
Common in the elderly
Symptoms present for over 6 months
June 2012 Biology 120: Medical Terminology 11
12. Alzheimer Disease
Form of dementia
No cure
Chronic mental disorder
Loss of memory, disorientation
Symptoms get worse with time
Occurs in people age 40-65
Earlier than age 40, early-onset Alzheimer Disease
June 2012 Biology 120: Medical Terminology 12
13. Medical Terminology
Neur/o – pertaining to nervous system
Neurology-study of nervous system
Neurologist- someone who studies nervous
system
Neuroma- swelling of brain, cancerous tumor in
brain
