Psych Unit 2

Psychology, Unit 2: Nervous System and Brain

QuestionAnswer
Nervous System Brain, nerve cells, spinal cord; involved in everything we do.
Central Nervous System Brain and spinal cord
Peripheral Nervous System The sensory and motor neurons that connect the central nervous system to the rest of the body
Neuron Nerve cell
Dendrite Branchlike parts of a neuron that are specialized to receive information.
Axon Long fiber that carries impulses away from the cell body of a neuron
Myelin Sheath A layer of fatty, electrical insulation that surrounds the axon.
Axon Terminal The endpoint of a neuron where neurotransmitters are stored
Synapse Gap between neurons
Neurotransmitter Chemical messengers that cross the synaptic gaps between neurons.
Sensory Nerves The nerves that carry sensations of touch, taste, heat, cold, pain, and other modalities from the body to the central nervous system.
Motor Nerves Nerves that carry information from the central nervous system to the muscles of the body.
Somatic System Part of the nervous system that controls voluntary muscles.
Autonomic System This controls involuntary muscles; includes sympathetic and parasympathetic systems
Sympathetic System Autonomic system that is activated during stress; 'fight or flight' response
Parasympathetic System Part of the autonomic system; operates under normal, peaceful conditions; helps restore & slow down activity, thus keeping the balance in the body
Frontal Lobe A lobe of the cerebral cortex that has specialized areas for movement, abstract thinking, planning, memory, and judgment
Parietal Lobe Lobe of the brain that processes tactile information, contains the somatosensory cortex.
Temporal Lobe A lobe on each hemisphere of the cerebral cortex near the temples that is the primary receiving area for auditory information
Occipital Lobe A lobe of the cerebral cortex that processes visual information
Left Hemisphere This side of the brain controls logic, problem solving, computation, recall
Right Hemisphere This side of the brain controls imagination, art, feelings, spatial relations
