Anatomy of the brain Flashcards
(9 cards)
Grey matter
Receives information and regulates outgoing information; outer layer known as the cerebral cortex (cortex latin for “bark”)– where the conscious mind is found
White matter
Allows for communication between gray matter, the spinal cord, and the central nervous system.
Cerebellum
coordinates voluntary movements, maintains balance, posture, equilibrium, unconscious motor learning (i.e. riding a bike while thinking about what you want for lunch) . New studies show it is also used in planning, remembering, and using emotions
Cerebrum
Consists of two hemispheres (left/right); 85% of the brain– made up of grey matter and white matter. Responsible for temperature regulation, speech, judgement, thinking, problem solving, learning, emotions, functions related to your 5 senses
Brainstem
Connects the cerebrum to the spinal cord; comprised of the midbrain, pons, and medulla
Midbrain: complex neuron structures; area that targeted by Parkinson’s Disease
Pons: tear production, chewing, blinking, facial expression
Medulla: regulates heart rhythm, breathing, blood flow; reflexes like sneezing, vomiting, swallowing
Frontal Lobe
Front of the head; personality, decision-making, planning, maintaining attention, movement, rational activity, sense of self and empathy, smell identification, Broca’s area (speech ability)
Parietal Lobe
Middle of the brain; identify objects, spatial awareness, interpret pain, Wernicke’s area (understand spoken language)
Temporal Lobe
Side of the brain; short-term memory, speech, musical rhythm, hearing, recognizing faces
Occipital Lobe
Back of the brain; responsible for vision (colours, forms, motion)– information relayed for the eyes and sent here
