Brain Areas & Their Function Flashcards
Central Nervous System
consists of the brain and spinal cord
Cingulate Glands
Belt bridge that covers the corpus callosum that plays an important role in attention and cognitive awareness
Medulla
Responsible for digestion, respiration, heart rate, breathing, and blood pressure
Pons
Sleep
Brain Stem
Includes; Medulla, Midbrain, and pons
Cerebellum
Motor coordination, balance
Midbrain
Coordinates movement with sensory input
Reticular activating system (RAS)
Process of arousal and tension
Limbic System
Emotional experiences/BASIC DRIVES of sex, aggression, hunger, and thirst
Caudate Nucleus
Controls motor behavior
Cerebral Cortex
Contains over 80% of neurons in the central nervous system
Left Hemisphere
Verbal and other cognitive processes
Right Hemisphere
Perceiving surrounding events and creating images
Temporal Lobe
Recognizing various sights and sounds
Parietal Lobe
Recognizing various sensations of touch
Occipital Lobe
Integrates various visual input
Frontal Lobe
Thinking and reasoning abilities
Peripheral Nervous System
Coordination with brain stem to ensure body is working properly (voluntary)
Somatic Nervous System
Controls our muscles
Autonomic Nervous System
Regulates the cardiovascular system and the endocrine system (involuntary)
Endocrine System
Releases hormones into the bloodstream. Regulates 4 glands; adrenal, gonads, pituitary, and thyroid.
Sympathetic Nervous System
Mobilizes body during times of stress (activating)
Parasympathetic Nervous System
Renormalizes body after arousal states
Pituitary Gland
Master or coordinator of endocrine system
