Chapter 10 –Nervous System I 1) Define the following word parts.
Ax-, axle: axon – cylindrical nerve process that carries impulses away from a neuron cell body.
Dendr-, tree: dendrite – branched nerve process that serves as the receptor surface of a neuron.
Funi-, cord, rope: funilicus – funiculi of spinal cord or bundle of nerve fibers.
Gangli-, knot: ganglia – deliver information to the body
-lemm, rind or peel: neurilemma – sheath that surrounds the myelin of a nerve cell process.
Mening-, meninges - The three fibrous membranes that surround the brain and spinal cord to protect the central nervous system.
Moto-, moving: motor neuron – neuron that stimulates a muscle to contract or a gland to release a secretion.
Peri-, all around: peripheral nervous system – portion of the nervous system that consists of the nerves branching from the brain and spinal cord.
Plex-, plexus; network of nerves. sens-, feeling: sensory neuron – neuron that can be stimulated by a sensory receptor and conducts impulses into the brain or spinal cord.
Syn-, together: synapse – junction between two neurons.
Ventr-, belly side of the body
2) What are the two types of cells that make up nervous tissue? nerve cells, or neurons, and neuroglial cells, or neuroglia.
3) What are the two major groups of nervous system organs?
Central Nervous System – brain and spinal cord
Peripheral Nervous System – cranial and spinal nerves that connect the CNS to other body parts
4) Define the following:
Dendrites – Small cellular processes that receive input
Axon – A long process that carries information away from the cell by nerve impulses; also called a nerve fiber
Nerve impulse – bioelectric signals
Nerves – bundles of axons
Synapse – the small space between a neuron and the cell with which it communicates
Neurotransmitters – biological messenger molecules that carry information
