Hey so I am new to this and am running very late on this assignment bc of 2 online tests I am having to take OUT OF NOWHERE tonight! Long story short idk what I am doing on here or how it works. But I really need a good grade on this. Heck I'd even pay something for it to be done. So I am hoping someone out there has these answers to the CD worksheets bc I just don't have the time. It would be greatly helpful. I know it is a good bit so................. ....


The Nervous System II: Anatomy Review
1.         The somatic nervous system stimulates ____________ muscle.
The autonomic nervous system stimulates ___________ muscle, ____________ muscle, and ___________.
2.         The autonomic nervous system (ANS) consists two divisions, each innervating the effector organs.  The sympathetic nervous system (SNS) generally speeds up everything except digestion.  The parasympathetic nervous system (PNS) generally slows down everything but digestion.
Signals from the SNS cause the heart rate to _________, while signals from the PNS cause the heart rate to ___________.
Signals from the SNS cause smooth muscles of the intestine to _________ contractions, while signals from the PNS cause these muscles to _________ contractions.
Signals from the SNS also cause the adrenal gland to _________ epinephrine and norepinephrine.
3.         Neurons can excite or inhibit another neuron.
Exciting another neuron will increase the chances of a/an ___________________ in the second neuron.
Inhibiting another neuron will make the chances of a/an __________________ less likely.
4.         Axons from one neuron can synapse with the dendrites or soma of another axon. 
These synapses are called ___________________ ___ (on dendrites) and ___________________ ______ (on soma).  They carry input signals to the other neuron.
Axons from one neuron can synapse with the axon terminal of another neuron.  These synapses are called ___________________ _____, and they regulate the amount of ___________________ _____ released by the other neuron.
5.         The electrical synapse:
Electrical current flows from one neuron to another through _________________.
These synapses are always (excitatory or inhibitory).
Advantages of the electrical synapses:
1. _______ signal conduction
2. _____________ activity for a group of neurons.
6.         The chemical synapse:
Chemical synapses are not as fast as electrical but are the most common type of synapse.
A chemical, called a ___________________ ___, is released from the sending neuron and travels across the ___________________(a gap between the neurons) to the receiving neuron.
Advantages of the chemical synapse:
1. The signal can be either ____________ or ____________.
2. The signal can be ______________ as it passes from one neuron to the next.
7.         The neuron conducting the impulse toward the synapse is called the __________________ neuron.  The axon terminal contains ___________ ____________ filled with ___________________ ___.
An action potential in the axon terminal of the _____________neuron causes the chemical transmitter ___________________ _ to be released.  It diffuses across the synaptic cleft and binds to receptors on the ________________ membrane.
These receptors open __________________.  The movement of the charged particles causes an electrical signal called a ___________________ ____.
