Unit 2 Notes:
The Brain
(1) Frontal Lobe• Speech Production (from Broca’s Area)
• Concentration, Problem Solving, Planning
• Voluntary Muscle Contractions
(2) Parietal Lobe• Interpretation of speech, sounds,
surroundings
• Pick up on skin sensations
(3) Temporal Lobe• Interpret sensations
• Visual & Auditory Memory• Basic Hearing function• Ability to learn + connect concepts
• Includes:– Thalamus– Hypothalamus– Pituitary Gland– Corpus Callosum– Limbic System
(4) Stuff In Your Temporal• Thalamus = Sensory reception
• Hypothalamus = Control Body Temperature, Maintain fluid + ion levels, Regulates Metabolism, Sleep
• Limbic System = Emotions
• Pituitary = Regulate hormone secretion
• Corpus Callosum = Connective tissue between left and right hemispheres
(5) Occipital Lobe• Vision
• Combines images to make complete picture
(6) Cerebellum• Coordinates muscle movement
• Maintains normal muscle tone
• DOES NOT MAKE MUSCLES MOVE!–Makes them move smoothly!
(7) Brain Stem• Passes info between spinal cord + brain
• Includes:–Midbrain– Pons–Medulla Oblongata
(8) Stuff in Brain Stem• Midbrain:– Fight or Flight responses (based of past)– Helps with vision + auditory senses
• Pons:– Respiratory Reflexes– General Breathing Rate
• Medulla Oblongata:– Maintains Homeostasis– Heartbeat, Blood pressure, Digestive reflexes– Also assists pons in respiration
