Chapter 48, Problem 13TYU
Summary Introduction
To explain: The distinct role of the gated ion channels in initiation of a signal and its passage along the nerve from the head of a rattlesnake till its tail and, then from that nerve to the muscle that moves the rattle.
Introduction:
Gated ion channels are necessary for the generation and propagation of impulses. The flow of ions induces many changes in the body. The gated ion channels work in response to stimuli and accordingly alters the membrane potential. The function of the gated ion channels present in the various organs is to cause conduction.

For you to see the words on your compute, quite a few different types of neurons are required. what types of neurons are involved in signal transmission for you to see the words? Describe all the neural structures fro required for seeing.
The action potential generated in the squid giant axon requires voltage-gated
potassium channels. Describe the shape of the action potential if these
channels are blocked using TEA (Tetraethylammonium).
Consider the circuit from Q5 (above). We want to add another inhibitory neuron to this circuit to increase the likelihood that neuron D will have an action potential. With which cell (A, B, C or D) should our new inhibitory neuron make a synapse to make it more likely that the post - synaptic neuron will have anaction potential?The diagram below shows a simple neural circuit with three pre - synaptic cells labelled 'A', 'B' and 'C', and a post - synaptic cell labelled 'D ' (see image below). Assume neurons A and B each have outputs of +2 and neuron C has output of -1.

- Conduction velocity refers to the [a] at which an action potential travels along a neuron's axon. In invertebrates, conduction velocity can only be increased by [b]. However in vertebrates (exclusively), such as humans, conduction velocity can also be increased by [c]. This enables vertebrates to conserve [d] while still increasing conduction velocity.

- Which of the following would you NOT expect with respect to variation in neural conduction velocity? Neural conduction speed increases over developmental time as Schwann cells synthesize myelin sheaths, insulating neurons Neural conduction velocity is higher in invertebrate species with insulating sheaths functionally equivalent to vertebrate myelin Neurons and species with larger axon diameters should have greater conduction velocities Neural networks with greater serial processing (i.e., lines of connecting neurons) should have greater neural conduction velocities. The thyroid hormones (triiodothyronine and thyroxine) have a range of roles in regulating growth and metabolism. Thyroid hormones act throughout the body to regulate protein synthesis, long bone growth, and neural maturation. This represents an ______ effect of thyroid hormones.

The action potential reaches the end of the axon, called the axon terminal, and a chemical signal is released to tell the target cell to do something, either initiate a new action potential, or to suppress that activity. In a very short space, the electrical signal of the action potential is changed into the chemical signal of a neurotransmitter, and then back to electrical changes in the target cell membrane. What is the importance of voltage-gated calcium channels in the release of neurotransmitters?arrow_forwardEvents in Synaptic Signal Transmission 1. Neurotransmitters are released into the synaptic cleft. 2. Neurotransmitters bind to ion channels. 3. Sodium ions enter into the dendrites. 4. Neurotransmitters are returned to the axon terminal, broken down by the enzymes or diffused away from the synapse. 5. Action potential arrives in axon terminal. 6. Synaptic vesicles containing the neurotransmitters fuse with the presynaptic membrane. 7. lon channels open.
