Consists of the brain stem pathway for all nerves entering and leaving the brain The Pons-- involved with sleep and alertness; connects brain and spinal cord The Medulla is the basic life support system. It directs our breathing, heart beating, and blood pressure The Cerebellum is involved with our balance and coordination 2 The Hindbrain (rear base of skull).

The Reticular Activating System relay area for information moving to other areas of the brain. important for attention, sleep, and arousal. 5 The Midbrain (above the pons
Midbrain
7 The Forebrain (covers brain’s central core) THE THALAMUS the main relay and switching area for the senses THE HYPOTHALAMUS concerned with bodily functions such as hunger, thirst, temperature, and sexual behavior. also involved with the fight or flight response to stress THE LIMBIC SYSTEM It is involved with strong emotions ( AMYGDALA) Memory ( hippocampus) THE CEREBRAL CORTEX protects the midbrain and the lower brain structures. Ability to learn and store complex info. and to think into the future
Forebrain
6. Hypothalamus 5. Thalamus 4. Cerebral Cortex
The Cerebrum Part of the forebrain Inside layer under cerebral cortex Two sides called hemispheres Control movement on opposite side of the body Left—speech, math, ability, and logic Right—vision, creative ability, intuition, and spatial relationship Hemispheres communicate through fibers called the corpus callosum
12 The Lobes of the Cerebral Cortex The Frontal lobe is involved with rational thought, planning, and organization The Parietal lobe is involved with body sensations, touch, pain, and temperature and the location of body positions. The Occipital lobe is involved with vision. The Temporal lobe is the main processor for hearing, memory, emotion, and speaking Each hemisphere consists of the four lobes..
