ANATOMY Unit 2 Notes: The Brain

(1) Frontal Lobe Speech Production (from Broca’s Area) Concentration, Problem Solving, Planning Voluntary Muscle Contractions Broca = produces speech

(2) Parietal Lobe Interpretation of speech, sounds, surroundings Pick up on skin sensations Wernicke = speech interpretation

(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
