NEURON TYPES $500 Name this specific red neuron. microtubules Motor neuron
DIVISIONS OF THE NERVOUS SYSTEM $100 Name the 2 main divisions of the Nervous System. Central NS & Peripheral NS
DIVISIONS OF THE NERVOUS SYSTEM $200 The Central Nervous System is comprised of the _______ and ______. Brain and spinal cord
DIVISIONS OF THE NERVOUS SYSTEM $300 The efferent peripheral nervous system is divided into what 2 sub- systems? Autonomic and Somatic
DIVISIONS OF THE NERVOUS SYSTEM $400 The autonomic division of the PNS is divided into what 2 subdivisions? Sypathetic and parasympathetic
DIVISIONS OF THE NERVOUS SYSTEM $500 You find yourself in a frightful situation. In terms of the sympathetic & parasympathetic nervous system, explain 3 body functions under smooth muscle, cardiac muscle and glands that are altered by EACH system.. DAILY DOUBLE Gland release norepinephrine releases adrenaline also called epinephrine
KNOW YOUR NEUROTRANSMITTERS $100 Choose from list! acetylcholine This NT is found in both the CNS and the PNS. It is involved in the control of skeletal muscle contractions. It stimulates skeletal muscle contraction at the neuromuscular junction.
KNOW YOUR NEUROTRANSMITTERS $200 Choose from list! dopamine This NT has its greatest effect in the CNS. It creates a sense of feeling good. Many “entertainment” drugs work by increasing this NT. Lack of it causes Parkinson’s disease.
KNOW YOUR NEUROTRANSMITTERS $300 Choose from list! Histamine This NT is released by the CNS and promotes alertness.
ACTION POTENTIAL $200 A normal resting neuron has a _______ on the outside. Negative Neutral Positive positive
KNOW YOUR NEUROTRANSMITTERS $400 Choose from list! serotonin This NT is only found in the CNS and is an inhibitory NT. It leads to sleepiness. The drug LSD blocks this action. On the other hand, certain reuptake drugs can enhance this NT.
KNOW YOUR NEUROTRANSMITTERS $500 Choose from list! Substance P Endorphins (enkephalins) This neuropeptide _______ is excitatory in the CNS leading to pain perception. However, in the PNS this neuropeptide ______ reduces pain by inhibiting the previously mentioned NT.
ACTION POTENTIAL $400 The sodium potassium pump moves # of these ions to the outside of the cell and moves # of these ions to the inside of the cell. Fill in the specific number and ion name. 3 Na out 2 K in
ACTION POTENTIAL $600 Name the 3 main ions involved in an action potential. Calcium, sodium, potassium
ACTION POTENTIAL $800 What is the SPECIFIC role of calcium in an action potential? It causes the neurotransmitter vesicles to move to the cell edge and undergo exocytosis.
ACTION POTENTIAL $1000 Discuss the relationship between these 3 parts of an ACTION POTENTIAL. Ligand Acetylcholine Sodium Voltage gate Acetylcholine acts as a ligand on the sodium voltage gate. The ligand causes the gate to open and allows Na to flow into the cell beginning the action potential. DAILY DOUBLE
VOCABULARY CH. 10 $200 biological messengers produced by neurons. neurotransmitter
VOCABULARY $400 Axon hillock the initial portion of an axon closest to the cell body where the action potential is started
VOCABULARY $600 White matter versus gray matter Myelinated versus unmyelinated
VOCABULARY $800. _____________ potential is a type of membrane change in which the receiving cell membrane is depolarized. excitatory postsynaptic
VOCABULARY $1000 Explain All-or- None Response. DAILY DOUBLE A nerve impulse is an all-or-nothing response, meaning if a neuron responds at all to a nerve impulse, it responds completely.
