1.Cell Bodies housing a nucleus: Is the part of the
|| || || || | || || || || ||
neuron that controls cell function
|| || || ||
2.What is the junction between a neuron and any other cell?:
|| || || || || || || || || || |
Synapse
3.Gray matter consists of: Collections of nerve cell bodies in
|| || || || || || || || || ||
the CNS
||
4.White matter consists of: Bundles of myelinated axons
|| || || || || || ||
5.The part of the neuron that recieves information: dendrites
|| || || || || || || |
6.What is the blood barrier created by?: astrocytes
|| || || || || || ||
7.What ion is needed to release a neurotransmitter from the
|| || || || || || || | || ||
synaptic vesicle- ||
: calcium
||
8.During the absolute refractory period, the cell: cannot be
|| || || || | || || || ||
stimulated
1 || / || 45
,9.what creates the myelin in the central nervous system:
|| || || || || || || || |
ogligodendrocytes
10.during the refractory period, the cell: responds only to
|| || || | || | || || ||
excessively strong stimuli || ||
11.an example of a circuit that involves two or more neurons
|| || || || || || || || || || ||
synapsing with a single post-synaptic neuron is a:
|| || || || || || || ||
convergent circuit ||
12.The myelin in the peripheral nervous system is created
|| || || || || || || || ||
by: neurolemmo- cytes
|| ||
13.Neurotransmitters are found stored in vesicles where: pre- || || | | | | ||
synaptic terminal ||
14.What ion causes depolarization in neurons: sodium
|| || || || || ||
15.What makes up the central nervous system: Spinal cord and
|| || || || || || || || ||
|| brain
16.Two main types of cells in the nervous tissue: neurons and
|| || || || || || || || | || ||
glial cells ||
17.Cranial nerves: originate from the brain; 12 pairs
|| || || || || || ||
2 || / || 45
,18.Spinal nerves: originate from the spinal cord; 31 pairs
|| || || || || || || ||
19.Ganglion: collection of neuron cell bodies outside the
|| || || || || || || ||
brain and spinal cord
|| || ||
20.Plexus: extensive network of axons, and sometimes
|| || || || || || ||
neuron cell bodies, located outside of the CNS
|| || || || || || ||
21.glial cells: supportive cells with many functions
|| || || || || ||
22.Functions of the nervous system: 1. Maintaining || || || || || || ||
homeostasis
2.Receiving sensory input || ||
3.Integrating information ||
4.Controlling muscles and glands || || ||
5.Establishing and maintaining mental activity || || || ||
23.Motor division of the PNS: somatic and autonomic nervous
|| || || || || || || ||
|| system
24.Sensory receptors: detect stimuli; send input along nerves
|| || || || || || ||
25.sensory (afferent): transmits action potentials from
|| || || || || ||
receptors to CNS || ||
3 || / || 45
, 26.Motor (efferent): transmits action potentials from CNS
|| || || || || || ||
to effectors (muscles, glands)
|| || ||
27.Somatic nervous system: from CNS to skeletal muscles.
|| || | || || || || ||
Is voluntary; single neuron system
