Divisions of the nervous system
The two major divisions of the nervous system
What is the CNS (central) and the PNS (peripheral)
This nerves function is the sensory for vision
What is optic nerve
Most numerous neuroglia in the CNS. Star-shaped and produce cerebrospinal fluid.
What are astrocytes
This is located in the cranial cavity, anterior to the cerebellum.
What is the brainstem
This is any language deficit resulting from damage to either Wernicke's or broca's area.
What is aphasia
This system conducts impulses from the CNS to cardiac muscles, smooth muscles and glands.
What is ANS (autonomic nervous system)
This nerve is the sensory for taste and the motor for facial expression
What is facial nerve (CN VII)
Small phagocytes that constantly wonder through the CNS. Important for defense. Smallest glial cells.
What are microglia
This are area interprets the messages by comparing it to what has come before.
What is association area
What is a nerve conduction study (NCS)
What system is composed of nerves carrying messages in two directions
This nerve is the motor for the tongue
What is hypoglossal nerve (CN XIII)
These neuroglia surround neuron cell bodies in the ganglia of the PNS. They regulate the chemical environment of ganglia in the PNS.
What are satellite cells
What is the cerebellum
This conduction results in the buildup of excess cerebrospinal fluid in the brain. It can result in mental retardation and abnormal physical development.
What is hydrocephalus
This system conducts impulses from the CNS to skeletal muscles
What is the somatic nervous system
This nerve is the motor for the trapezius, sternocleidomastoid and muscles of the larynx.
These neuroglia form myelin around the axons in the CNS
What are oligodendrocytes
These are groups of cell bodies located throughout the brainstem
What is reticular formation
The electrical potential difference across a cell membrane when the cell is at rest. This potential is usually around -70 millivolts
What is resting membrane potential
This system is composed of the brain and spinal cord and serves as a processing center.
What is the CNS (central nervous system)
The nerve that is the sensory for pain, touch, and temperature for the eye and lower and upper jaws.
This neuroglia form myelin in the PNS and help damaged myelinated axons regenerate
What are schwann cells
The largest subdivision, divided into 2 hemispheres. It controls the contralateral side of the brain.
This type of neuron with one dendrite and one axon. It is found in the nasal cavity, the retina of the eye, and the inner ear.
What is bipolar
