5. Parts of the Brain: Cerebrum
The cerebrum is the makes up most of the brain mass
It is responsible for:
Voluntary motor function
Senses
Integration of information
It is divided into two hemispheres
Right and left hemisphere controls the opposite side
Each hemisphere has 5 lobes
Frontal
Parietal
Temporal
Occipital
Insula

6. Parts of the Brain: Cerebrum
Cerebral Lobes: Anatomy & Physiology
Frontal Lobe
Thinking, creativity, motor functions
Parietal Lobe
Memory, senses
Temporal Lobe
Controls hearing, speech, & memory
Occipital Lobe
Vision
Insular Lobe
Not sure of function. Believed to deal with feelings involving pleasure.

13. Parts of the Brain: Brain Stem
The brain stem is composed of:
Midbrain
Acts as a relay centers for other brain parts
Controls some reflexes
Causes fear responses
Pons
Connects cerebellum to rest of the brain
Helps to maintain breathing
Medulla Oblongata
Controls many autonomic reflexes
Controls respiratory and heart rates and blood pressure

15. Parts of the Brain: Diencephalon
Central core of the forebrain
Consists of three paired structures:
Thalamus
Hypothalamus
Epithalamus

16. Parts of the Brain: Diencephalon
Parts of the Diencephalon
Thalamus
Interprets cerebral senses
Involved in memory processing
Hypothalamus
Integration center of involuntary nervous system (autonomic)
Regulates many processes needed for homeostasis
Regulates hormones (endocrine system)
Controls emotions
