Subdivisions
The 2 main functional subdivisions of the nervous system
What are the central and peripheral nervous systems?
The primary skeletal protection for the brain and spinal cord
What are the skull and vertebral column?
The 4 major regions of the brain
What are the brain stem, cerebrum, cerebellum, and diencephalon?
The name for the projection of gray matter on the dorsal side of the spinal cord
What is the dorsal horn?
Support cells of the Nervous System collectively
What are neuroglia?
The brain and spinal cord
What is the central nervous system
The plasma-like fluid produced by the choroid plexus of the ventricles.
What is cerebrospinal fluid?
The midbrain, pons, and medulla oblongata
The number of pairs of spinal nerves that emerge from the spinal cord
What is 31 pairs?
Form the myelin sheath of neurons in the PNS
What are oligodendrocytes?
What are Schwann cells?
What is the sympathetic nervous system?
The correct sequence of connective tissue sheaths around nerve fibers and nerves from outermost to innermost.
What are epineurium, perineurium, and endoneurium?
The thalamus, hypothalamus, and epithalamus collectively
The gray matter surrounds this medial chamber which contains the CSF for the spinal cord
What is central canal?
Type of neuroglia that filter the blood from capillaries and provide structure for neurons
What are astrocytes?
The divisions sympathetic and parasympathetic are the arms
What is the Autonomic Nervous System?
The tight capillary junctions that protect against the passage of water soluble substances/chemicals, excluding glucose, essential amino acids, and water.
The large fiber tract of connective tissue that allows communication between the cerebral hemispheres
What is the corpus callosum (*gummy worm)?
What the ventral roots and dorsal roots fuse to form
What is a spinal nerve?
Type of neuron that connects sensory and motor neurons (acts in reflexes)
The subdivision of the PNS that controls skeletal muscles
What is the somatic nervous system?
The correct sequence of protective connective tissue in the CNS from outermost to innermost
The general term given to the protective layers of connective tissue
What is dura mater, arachnoid mater, and pia mater?
What are meninges?
What is the thalamus?
The collection of nerves at the inferior end of the vertebral canal (looks much like a horse's tail)
What is a cauda equina?
The gaps in between Schwann cells in peripheral nervous system neurons.
The part of the neuron that typically conducts nerve impulses away from the body.
What are nodes of Ranvier?
What is the axon?
