The Basics of the Not Basic Nervous System
The part of the nervous system that is protected by bone.
What is the central nervous system?
Tumors that are often benign that occur on nerves and tracts
What is neuroma?
The type of axons the term "nerve" refers to.
What are axons present in the peripheral nervous system?
Part of the neuron that contains the nucleus, vital organelles, and where information received by the neuron is processed.
What is the soma?
The three basic functions of the nervous system.
What is sensation, response, and integration?
The term that refers to a group of neuron cell bodies that are present in the central nervous system.
What are nuclei?
Disease associated with the degradation of the myelin sheath
What is multiple schlerosis?
The layers of structures of a nerve, from the most superficial layer to the deepest layer.
What are the epineurium, nerve, perineurium, nerve fascicle, endoneurium, neurilemma, myelin sheath, axon, axolemma, and axoplasm?
Neurons that receive a signal from the periphery system and transmit the signal to the central nervous system?
What are sensory neurons?
Part of the nervous system that regulates involuntary control for the purpose of homeostasis, such as sweating when hot.
What is the visceral motor subdivision or automatic nervous system?
Cells that protect and support neurons in the central and peripheral nervous systems.
What are glial cells?
The cause of most nervous system cancers and tumors?
What is the excessive division of glial or connective cells?
Irregular, dense tissue that protects the top of the nerve from injury.
What is the epineurium?
Responsible for transmitting signals between the two different types of neurons. Found only in the central nervous system.
Interneurons
Responsible for perception and contraction of the skeletal system.
What is the somatic nervous system?
Special properties that all neurons in the body exhibit?
What is excitability, conductivity, and secretion?
The three parts of a nerve that are required for regeneration?
What are schwann cells, the neurilemma, and the endoneurium?
Connective tissue that allows for nutrients to permeate the glial-axon unit contained within it.
What is the endoneurium?
Phospholipid layers around the outside of the axon that insulate the electrical signal being sent between neurons.
What is the myelin sheath?
Controls the smooth muscle of the digestive system.
What is the enteric nervous system?
Cells that are exclusively sensory cells that have only one process.
What are unipolar neurons?
The step of nerve regeneration that occurs after an injury.
What is the enlargement of the soma and the growth of new processes at the location of the damage?
Cells that insulate and are closest to the axon.
What are Schwann cells?
Type of cell that increases the speed of the electrical signal between tracts.
What is an oligodendrocyte?
The part of the nervous system that is functioning when an individual notices that their stomach is hungry.
What is the visceral sensory subdivision?
