hormones. The Pituitary is a master gland whose con master Is The hypothalamus,

Question 3

hindbrain:

Answer 3

1 of the 3 major regions of the brain, its 3 main parts are:
Brainstem; brain’s oldest innermost region. it is the central core of the brain it is responsible for automatic survival functions
Medulla: The base of brainstem, controls heartbeat and breathing
Cerebellum: little broin, Processing sensory input, coordinating movement output and balance, and skill memory,

Question 4

Thalamus:

Answer 4

brain sensory and control center it directs messages to The Sensory receiving areas in the cortex and transmits to cerebellum and medulla. rout information from all senses except smell.
Center of train station.

Question 5

reticular formation

Answer 5

a nerve network that travels Through The brainstem into the Thalamus and plays an important role in controlling arousal.

Question 6

Limbic system

Answer 6

limbic system associated with emotions and drives includes
Amygdala linked to emotion
hypothalamus directs maintenance activities like eating drinking and
Hippocampus: help process explicit memories for storage

Question 7

Cerbal cortex,

Answer 7

intricate fabric of inter connected neural cells covering the cerebral hemispheres; body’s ultimate control and Information processing center.

Question 8

• Corpus Callosum

Answer 8

allows the two hemispheres to talk to each other

Question 9

Function of the four lobes:

Answer 9

Samato sensory: body touch and movement sensations
