Study Notes
Multiple Choice Questions
- The two major divisions of the nervous system are the PNS and CNS.
- The CNS consists of the brain and brain stem.
- The ANS is part of the PNS.
- The somatic nervous system is part of the PNS.
- Afferent nerves carry sensory information to the CNS.
Additional Questions
- Neurons in the sympathetic nervous system are part of the peripheral nervous system.
- The parasympathetic nervous system projects from only cranial and sacral portions of the CNS.
- The sympathetic nervous system's first-stage neurons synapse at a substantial distance from the target organ, whilst the parasympathetic nervous system's first-stage neurons synapse close to the target.
- The parasympathetic nervous system generally conserves the body's energy.
- The first two cranial nerves are sensory.
- The vagus nerve is part of the parasympathetic nervous system and is the tenth cranial nerve. It is also the longest cranial nerve.
- Dura mater, arachnoid membrane, and pia mater are meninges.
- In order, the three meninges are dura, arachnoid, and pia.
- CSF adheres to the surface of the brain called the pia mater.
- There are four ventricles in the brain.
- CSF circulates through the central canal and subarachnoid space.
- The blood brain barrier impedes the passage of large molecules into cerebral neurons.
- Neurons are specialized to receive, conduct, and transmit electrochemical signals.
- The cone-shaped structure at the boundary between the cell body and axon of a multipolar neuron is called the axon hillock.
- The soma of a neuron is the cell body.
- The part of a neuron that is sometimes myelinated is the axon.
- Communication among neurons frequently occurs at points where axons contact each other or across synapses.
- Neurons predominantly have DNA within their nucleus.
- Synaptic vesicles are commonly found in postsynaptic membranes.
- The neuron membrane contains a lipid bilayer, and channel and signal proteins.
- Multipolar neurons have one axon and several dendrites coming off of the cell body.
- Interneurons primarily integrate activity within a single brain structure.
- Clusters of neural cell bodies in the CNS are called nuclei.
###Additional Information
- The dura mater, arachnoid membrane, and pia mater are meninges.
- The spinal cord has gray matter with four arms or horns.
- There are 31 pairs of dorsal roots in the human body.
- Neurons in the dorsal roots are sensory neurons, and neurons in the ventral roots are motor neurons.
- "Encephalon" refers to structures within the head.
- The cerebral hemispheres are connected by tracts called commissures.
- The longitudinal fissure separates the two hemispheres of the brain.
- The temporal lobe is separated from the frontal lobe by the lateral fissure.
- Pyramidal, stellate, and fusiform cells are neurons.
