[2]
- how many pounds if your brain?
- how many neurons in the brain?
- how many synaptic connections for an average neuron to other neurons?
- what percent of body oxygen and glucose is used by the brain?
- Your brain uses up ten times more energy when you're thinking hard - (answers)- 3 lbs
- 86 billion
- 1000 and up to 200,000 Purkinje cells
- 20%
- False
[2] What is the level of organization of the nervous system? - (answers)Cells: individual neurons
Tissue: nerves, ganglia
Organ: brain and spinal cord
,System: nervous system
[2] soma - (answers)cell body of a neuron
[2] dendrite - (answers)branched, treelike extensions attached to the soma of a neuron; receives
information from neurotransmitters released from terminal button
[2] axon - (answers)extension of a neuron, ending with branching terminal fibers which send
messages to other neurons or muscles or glands
[2] terminal button - (answers)bud at the end of a branch of an axon; forms synapses with other
neurons; sends information to those neurons via neurotransmitters
[2] neurotransmitter - (answers)chemical released by a terminal button; has an excitatory or
inhibitory effect on other neurons
[2] myelin sheath - (answers)- covers the axon with a layer and prevents messages from traveling
between each sheath
- composed of glial cells (support cells of CNS)
, - increases speed of neural impulses (jumps from each node of Ranvier to another)
- decreases amount of energy needed for neural conduction
[2] action potential - (answers)all or none phenomenon; propagates a firing from one end of the
axon to the other
[2] synapse - (answers)junction between terminal button of a neuron and membrane or dendrite
of another
[2] synaptic gap - (answers)area where neurotransmitters are released into after an action
potential makes it to the terminal button, triggering the release of presynaptic membrane (holding
the neurotransmitters)
- released into synaptic cleft
[2] neurotransmitter - (answers)chemical released to bind to receptor sites; may cause inhibitory
or excitatory effects
[2] reuptake - (answers)transporters return neurotransmitters to the terminal button and the
postsynaptic effects are stopped (back into cytoplasm)
