Chapter 2c Flashcards
The intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body’s ultimate control and information-processing center.
Cerebral Cortex
The portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgements.
Frontal Lobes
The portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position.
Parietal Lobes
The portion of the cerebral cortex lying at the back of the head; includes areas that receive information from the visual fields.
Occipital Lobes
The portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear.
Temporal Lobes
An area at the rear of the frontal lobes that controls voluntary movements.
Motor Cortex
An area at the front of the parietal lobes that registers and processes body touch and movement sensations.
Somatosensory Cortex
Areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking.
Association Areas
The brain’s ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience is referred to as:
Plasticity
A condition resulting from surgery that isolates the brain’s two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them.
Split Brain
We refer to a neurotransmitter’s reabsorption by the sending neuron as:
Reuptake
_______________ are part of the neuron that receive and integrate messages, conducting impulses toward the cell body.
Dendrites
The neuron extension that passes messages through its branches to other neurons or to muscles or glands is known as a(n):
Axon
The _______________ nervous system enables voluntary control of our skeletal muscles, while the _______________ nervous system controls our glands and internal organ muscles.
Somatic; autonomic
The division of the autonomic nervous system that arouses and expends energy is the:
Sympathetic Nervous System
This division of the autonomic nervous system calms the body and conserves its energy.
Parasympathetic Nervous System
The part of the brainstem that controls your heartbeat and breathing is the:
Medulla
The body’s ultimate control and information processing center is the:
Cerebral Cortex
Judging and planning are enabled by the _______________ lobes.
Frontal
