Anatomy of Brain
Lower forebrain. Interpretation and relaying of sensory information. It receives information from all senses except smell. Organizes all information and relays it to higher brain areas.
Lower forebrain. Regulates many processes. It controls hunger, thirst, sexual arousal, emotional responses, bodies' internal temperature.
Midbrain, includes amygdala, and hippocampus. collectively involved in emotional expression, memory, and motivation.
Forebrain. Triggers aggressive and fear responses. Connection of sensations and emotions. Limbic system.
Transfer of information between the two cerebral hemispheres. Bundle of nerves.
Two lobes at the front of the cortex. One on each side of the brain. Mostly plan actions and show normal social and emotional behavior. Gives one self-awareness.
Two lobes at the upper middle of the cortex. One on each side of brain. They contain the somatosensory area where feeling sensations are processed.
Two lobes at the side of the cortex. One on each hemisphere. They contain areas important to hearing and understanding speech.
Two lobes at the back of the cortex on each side of the brain. They contain areas important to vision.
Hindbrain. Produces chemicals, regulates sleep.
Hindbrain. Controls vital reflexes. Regulation of breathing, heart rate and blood pressure.
Hindbrain. Control of finely coordinated movements. Coordination center, voluntary movement and balance. "Small brain."
Somatic Nervous System
voluntary system, controls skeletal muscles; interacts with external environment.
Autonomic Nervous System
Involuntary system, regulates body's internal environment, including organs, glands, blood vessels.
Sympathetic Nervous System
Prepares body for action; mobilizes energy resources.
Parasympathetic Nervous System
Conserves body's energy; returns body to normal, quiet state after an emergency.
located in brain, releases growth hormone, regulate glands
neck, releases throxin, effects metabolism
releases adrenaline, epinephrine, norepinephrine, corticoids
releases insulin into blood regulate sugar
