Anatomy of the Nervous System
| Question | Answer |
|---|---|
| The central nervous system (CNS) contains the brain and the | spinal cord |
| The peripheral nervous system (PNS) contains the cranial nerves and the | spinal nerves |
| The largest part of the CNS is the | brain |
| The brain is located within the | cranium |
| The brain is surrounded by three layers of membranes called the | meninges |
| The largest and most obvious part of the brain is the | cerebrum |
| The "gray matter" of the brain is called the | cerebral cortex |
| The brain is divided into right and left halves. Each half is called a | hemisphere |
| The only connection between the right and left halves of the brain is the | corpus callosum |
| Each hemisphere of the brain is divied into | lobes |
| The speech center of the brain is in the | frontal lobe |
| The lobe that analyzes information about touch, temperature, vibration, and pain is the | parietal lobe |
| The lobe of the brain that analyzes sensory information about hearing is the | temporal lobe |
| The lobe of the brain that analyzes information about vision is the | occipital lobe |
| The object that is located near the center of the cerebrum and acts as a relay station for the brain is the | thalamus |
| The object that is located directly beneath the thalamus and coordinates the heart rate, blood pressure, and respiration is the | hypothalamus |
| The four interconneced cavities within the brain are known as | ventricles |
| The clear, colorless fluid that cushions and protects the brain and spinal cavity is the | cerebrospinal fluid |
| The column of tissue that begins in the center of the brain and coninues inferiorly until it meets the spinal cord is the | brain stem |
| The brainstem is composed of the midbrain, the pons, and the | medulla oblongata |
| The most superior part of the brainstem that keeps the brain conscious is the | midbrain |
| The separate rounded section of the brain that lies inferior and posterior to the cerebrum that helps the body to maintain balance and coordination is the | cerebellum |
| The outermost layer of the meninges is the | dura mater |
| The second weblike layer of the meninges is the | arachnoid |
| The innermost layer of the meninges is the | pia mater |
| The long narrow column of neural tissue within the spinal cavity is called the | spinal cord |
| The PNS contains 12 pairs of | cranial nerves |
| A rapid, involuntary muscle reaction that is controlled by the spinal cord is called a | reflex |
| An individual nerve cell is called a | neuron |
| The neural tissue that performs specialized tasks to help neurons do their work and whose name literally means "nerve glue" are called | neuroglia |
| The system that controls voluntary movements of the skeletal muscles is the and whose abbreviation is SNS is the | somatic nervous system |
| The system that control the involuntary contractions of cardiac muscle in the heart as well as the smooth muscle of organs is the | autonomic nervous system |
| The part of the system that is active when the body is resting, sleeping or eating is the | parasympathetic division |
| The part of the system that is active when the body is active or exercising is called the | sympathetic division |
| The multiple branching structures at the beginning of a neuron are called | dendrites |
| The chemical messenger that travels across a synapse to bind with a receptor in the neuron is called a | neurotransmitter |
| The space between two neurons is called a | synapse |
