What are the 3 functions of the ‘FRONTAL LOBE’?
What part of the ‘BRAIN’ is it located on?
- MOTOR AREA
- ELABORATE THOUGHT
- SPEAKING ABILITY
LOCATED ON ‘CEREBRUM’
What are the 3 functions of the ‘PARIETAL LOBE’?
What part of the ‘BRAIN’ is it located on?
- SENSORY AREA
- BODY FEELINGS/TOUCH/PRESSURE/HEAT/COLD/PAIN
- BODY POSITIONS
LOCATED ON ‘CEREBRUM’
Which ‘LOBE’ of the ‘CEREBRUM’ is connected with ‘SOMESTHETIC’ and ‘PROPRIOCEPTION’ sensations?
‘PARIETAL LOBE’
SOMESTHETIC = SENSES IN SKIN/BODY
PROPRIOCEPTION = POSITION PERCEPTION

What part of the ‘BRAIN’ is it located on?
HEARING
LOCATED ON ‘CEREBRUM’
What is the sole function of the ‘OCCIPITAL LOBE’?
What part of the ‘BRAIN’ is it located on?
VISUAL INPUT
LOCATED ON ‘CEREBRUM’
What is the ‘CEREBRAL CORTEX’?
Where is it located?
GRAY MATTER (6 LAYERS OF NEURONS)
LOCATED ON THE ‘OUTER PORTION’ OF THE ‘CEREBRUM’ (3/16”)
What are the 6 ‘various’ ‘FUNCTIONS’ of the ‘CEREBRUM’?
- ALL ‘CONSCIOUS’ FUNCTIONS
- INTERPRETATIONS OF SENSATIONS
- UNDERSTANDING OF LANGUAGE
- INTELLIGENCE
- MEMORY
- EMOTIONAL FEELINGS
The ‘THALAMUS’ is located ‘right’ next to what other part of the ‘BRAIN’?
HYPOTHALAMUS
The ‘THALAMUS’ has 4 main functions. What are they?
- CRUDE SENSATION OF PAIN, TEMPERATURE, TOUCH
- PLEASANT/UNPLEASANT FEELINGS
- COMPLEX REFLEX MOVEMENT PRODUCTION
- IS A ‘RELAY CENTER’
(RECEIVES ‘ALL’ SENSORY INPUT EXCEPT FOR ‘SMELL’.
Which part of the ‘BRAIN’ is considered to be the ‘RELAY CENTER’?
‘THALAMUS’
*RELAY CENTER = RECEIVES ‘ALL’ SENSORY INPUT (EXCEPT FOR SMELL) AND RELAYS TO ‘SENSORY CORTEX’
Which part of the ‘BRAIN’ is connected with the ‘RECOGNITION OF CRUDE SENSATIONS OF PAIN, TEMPERATURE AND TOUCH’?
THALAMUS
Which part of the ‘BRAIN’ is connected with ‘PLEASANT/UNPLEASANT FEELINGS’?
THALAMUS
Which part of the ‘BRAIN’ is connected with ‘COMPLEX REFLEX MOVEMENT PRODUCTION’?
THALAMUS
What are the 4 functions of the ‘HYPOTHALAMUS’?
- CONTROLS THE ‘PITUITARY’
- WATER BALANCE
- APPETITE AND FOOD INTAKE
- BODY TEMPERATURE
- INDIRECT/DIRECT INPUTS TO ‘AUTONOMIC’ NERVOUS SYSTEM
Which part of the ‘BRAIN’ is connected with ‘CONTROLLING THE PITUITARY’?
