Chapter 2-Second Half Flashcards
Medulla
The base of the brainstem, controls heart beat and breathing
Brainstem
Oldest part; central core of the brain, responsible for automatic survival functions
Reticular Formation
A nerve network in the brainstem that plays an important role in controlling arousal
Thalamus
Sensory switch board, found at the top of the brainstem, directs messages to sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
Hippocampus
Processes memory
Pons
Sits above the medulla, helps coordinate movement
Cerebellum
“Little brain” rear of the brain stem, processes sensory input and coordinating movement output and balance
Limbic System
Deals with emotions, like fear, and aggression, drives for food and sex, includes: hippocampus, amygdala, and hypothalamus
Amygdala
Two Lima bean sized neural clusters that are components of the limbic system and are linked to emotion
Hypothalamus
A neural structure below the thalamus, directs several maintenance activities(eating, drinking, body temp), helps govern endocrine system via pituitary gland, linked to emotion
Cerebral cortex
Intricate fabric of interconnected neural cells that covers the cerebral hemispheres; the body’s ultimate control and processing center
Glial Cells
Cells in the nervous system that support, nourish, and protect neurons
Frontal Lobe
Portion of cerebral cortex lying just behind the forehead, used for speaking, muscles movements, making plans, and judgements
Occipital Lobe
Portion of the cerebral cortex, at the back of the head, visual areas, receives visual info from the opposite visual fields
Parietal Lobes
Portion of the cerebral cortex, top of the head towards the rear, recovers sensory input for touch and body position
Temporal Lobes
Part of the cerebral cortex, lies roughly above the ears, receives auditory info from opposites sides
Motor cortex
Rear of the frontal lobes, controls voluntary movement
Sensory cortex
Area in the front of the parietal lobes registers and processes body touch and movement sensations
Association Areas
Areas of the cerebral cortex that involve higher mental functions such as learning, remembering, thinking and speaking
Aphasia
Impairment of language; caused by damage to the left hemisphere in the Broca’s area (impairing speaking) or to Wernick’s area impairing understandingly
Broca’s Area
Controls language expressions, frontal lobe left hemispheres directs muscles movement involved in speech
Wernicke’s Area
Controls language reception comprehension and expression left temporal lobe
Plasticity
Brains ability for modification after some form of damage
Corpus Callosum
The large band of neural fibers connecting the two brain hemispheres and carrying messages between them
Split Brain
A condition km which the fibers connecting the two hemispheres are split
Phineus Gage
Building railroads, had a metal rod pierce his skull pierce his frontal lobe, he lost his ability to plan and make judgements, and his personality changed, he became mean
