Insula
What is the largest part of the brain?
Cerebrum
Describe the main purpose of the brain stem
Connects the diencephalon and the cerebrum to the spinal cord

Hypothalamus
List the lobes of the cerebrum
Frontal
Parietal
Temporal
Occipital & Insula(central lobe)
What is the occipital lobe involved in?
Vision
Describe the main function of the thalamus
Transmits most of the sensory impulses to the cerebral cortex
How many parts is the cerebrum divided into?
To halves known as the cerebral hemispheres
Frontal lobe is involved in?
Decision making, memory, judgement
Parietal lobe is involved in?
Processing, reception, movement
Temporal lobe is involved in?
Memory, emotions, language (speaking&understanding) and hearing
Occipital lobe is involved in ?
Vision
Insula (central/mid lobe) is involved in?
Cravings, addiction, sex drive
What does the corpus collusum conmect?
The two hemispheres of the cerebrum together
The diencephalon is the ….
2nd part of the cerebrum
Where is the diencephalon located?
Between the cerebral hemispheres & superior(above)to the brain stem
What are the 3 major regions of the brain stem?
Mid brain
Pons
Medulla oblongata
How many cranial nerves are in the brain stem?
12
3-Mid Brain
4- pons
5- Medulla oblongata
Mid brain controls?
Visual & auditory reflexes
Pons transmits?
Motor activity to the brain & back
Medulla oblongata controls?
Vital processes such as : heart rate, breathing, blood pressure
Where is the Cerebellum located?
Below the occipital lobes of the cerebrum
Cerebrum causes the body to move how?
Smooth not not jerky
The cortex is filled with what?
Grey matter
How is the cortex connected to the rest of the brain?
Using penduncles ( inferior, middle, superior)
Penduncles are what?
Fibers
Describe the epithalamus
Covers thalamus and contains pineal gland
Describe thalamus
Makes up 80% of diencephalon
Made of 2 large masses of grey matter
Transmits most sensory impulse(not smell) to the cerebral cortex
Starts the emotional responses to sensory impulses
Describe hypothalamus
Foun beneath thalamus
Controls TEMPERATURE & ENDOCRINE SYSTEM
Endocrine system controls?
Hormones in the body
food intake and sex drive
